A good pairing is based on the complementary role of wine on the four important factors of food: components, textures, flavors and colors. Common wine and food examples of food preparation with wine or vine products, such as grapes or vine leaves, exemplify numerous similarities and contrasting characteristics in those four parameters, which we can find in an enjoyable meal. The knowledge of the internal anatomy and composition of both grape berries, which includes the skin, the mesocarp and the endocarp, and vine leaf, which includes the vascular system, parenchymatous mesophyll and epidermis, is essential to know how to develop new, tastier and healthier dishes. An understanding of these ideas is important when defining gastronomic tourism strategies and even local restaurant concepts and ideas. The aim of this review is to provide some insights about the sensory experiences offered by culinary dishes cooked with grapes, vine leaves and wines and other alcoholic beverages like distilled spirits and liqueurs, bearing in mind that wine will be the drink of elation for accompanying such dishes.

Despite the increased sales of wine in Korea, fewer Koreans consume wine with Korean food, although many Koreans believe that Western food pairs well with wine. This could reduce wine consumption in Korea and critically influence the future growth of the Korean wine market. Therefore, this study aims to develop Korean food and wine pairing criteria by examining the adaptability of food and wine pairing guidelines to the Korean palate. This exploratory study uses sequential mixed methods. The qualitative study was done by performing 12 one-on-one interviews and one focus group interview. The characteristics influencing Korean food and wine pairing were identified from the qualitative study. The quantitative study was followed by a survey of Korean wine consumers. Of the 151 questionnaires distributed, 138 valid responses were received. The qualitative results were tested and showed the following outcomes: spiciness, strong flavors, and hot food temperature were identified as three specific characteristics that hinder wine pairing. Although wine-friendly Korean dishes did not commonly include those features. Koreans’ daily diet has influenced their different wine preference. A segment of Korean wine consumers enjoy the burning sensation in the mouth and prefer to match tannic red wine to spicy dishes. As a result, nine criteria of Korean food and wine pairing were developed. Among them, two criteria were newly identified from this research, and are the main focus of this study: wine with an oak flavor pairs well with food that has a soy sauce flavor; and dry, tannic wine can be paired with spicy dishes.

The organic food market is considerably expanding all over the world, and the related dairy market represents its third most important sector. The reason lies in the fact that consumers tend to associate organic dairy products with positive perceptions: organic milk is eco- and animal-friendly, is not produced with antibiotics or hormones, and according to general opinion, provides additional nutrients and beneficial properties. These factors justify its higher cost. These are the reasons that explain extensive research into the comparison of the differences in the amount of chemical compounds between organic and conventional milk. However, it is not simple to ascertain the potential advantage of organic food from the nutritional point of view, because this aspect should be determined within the context of the total diet. Thus, considering all the factors described above, the purpose of this work is to compare the amount of selected nutrients (i.e., iodine and the fat-soluble vitamins such as alfa-tocopherol and beta-carotene) in organic and conventional milk, expressed as the percentage of recommended daily intakes in one serving. In detail, in order to establish the real share of these biologically active compounds to the total diet, their percent contribution was calculated using the Dietary Reference Values for adults (both men and women) adopted by the European Food Safety Authority. According to these preliminary considerations, the higher cost of organic milk can mainly be explained by the high costs of the management of specific farms and no remarkable or substantial benefits in human health can be ascribed to the consumption of organic milk. In this respect, this paper wants to make a small contribution to the estimation of the potential value and nutritional health benefits of organic food, even though further studies are needed.

High-fat diets (HFD) increase lipopolysaccharide (LPS) activity in the blood and may contribute to systemic inflammation with obesity. We hypothesized that dietary milk sphingomyelin (SM), which reduces lipid absorption and colitis in mice, would reduce inflammation and be mediated through effects on gut health and LPS activity. C57BL/6J mice were fed high-fat, high-cholesterol diets (HFD, n = 14) or the same diets with milk SM (HFD-MSM, 0.1% by weight, n = 14) for 10 weeks. HFD-MSM significantly reduced serum inflammatory markers and tended to lower serum LPS (p = 0.08) compared to HFD. Gene expression related to gut barrier function and macrophage inflammation were largely unchanged in colon and mesenteric adipose tissues. Cecal gut microbiota composition showed greater abundance of Acetatifactor genus in mice fed milk SM, but minimal changes in other taxa. Milk SM significantly attenuated the effect of LPS on pro-inflammatory gene expression in RAW264.7 macrophages. Milk SM lost its effects when hydrolysis was blocked, while long-chain ceramides and sphingosine, but not dihydroceramides, were anti-inflammatory. Our data suggest that dietary milk SM may be effective in reducing systemic inflammation through inhibition of LPS activity and that hydrolytic products of milk SM are important for these effects.

The objective of this study was to mix beet juice and orange juice in two proportions (1:1 and 1:2 v/v), evaluate their physicochemical stability and antioxidant activity during storage (4 °C for 30 days), and evaluate their acceptance by consumers. Beet juice (with or without pasteurization) and pasteurized orange juice were used as controls. The presence of orange juice contributed to the pH, betacyanin, betaxanthin, and antioxidant capacity stabilities during storage, whereas the presence of beet improved the color stability. The mixed juices showed high total phenolic compounds (484–485 µg gallic acid/mL), DPPH scavenging capacity (2083–1930 µg Trolox/mL), and ABTS (1854–1840 µg Trolox/mL), as well as better sensory acceptance than the pasteurized beet juice. However, the mixed juices had a more significant reduction in the ascorbic acid content (completely lost at 15 days of storage) than the pasteurized orange juice (25% reduction at 30 days). The beet and orange mixed juice is an alternative functional beverage that can contribute to an increase in the consumption of beet and orange. Full article

Lactose is the major disaccharide found in milk, and is catabolized into glucose and galactose by the enzyme lactase. Lactose is an important energy source and ssometimes it is referred to simply as milk sugar, as it is present in high percentages in dairy products. Lactose is the primary source of carbohydrates during mammal development, and represents 40% of the energy consumed during the nursing period. Lactose-intolerance individuals have a lactase deficiency; therefore, lactose is not completely catabolized. Lactose intolerance is a significant factor in the choice of diet for many sick people, therefore its content in foods must be monitored to avoid disorders and illnesses. This has created the need to develop simple methods, such as polarimetry, gravimetric, middle infrared, differential pH and enzymatic monitoring, but all these methods are time-consuming, because they required extensive sample preparation and cannot differentiate individual sugars. In order to quantify low levels of lactose, new and more accurate analytical methods have been developed. Generally, they require equipment such as HPLC or High Performance Anion Exchange with Pulsed Amperometric Detection (HPAE-PAD). Full article

Donkey milk could be considered a good and safer alternative, compared to other types of milk, for infants affected by cow’s milk protein allergy, when breastfeeding is not possible. Interestingly, donkey milk has low allergenicity, mainly due to the low total casein amount, and the content of some whey proteins that act as bioactive peptides. The amount of lysozyme, an antibacterial agent, is 1.0 g/L, similar to human milk. Lactoferrin content is 0.08 g/L, with this protein being involved in the regulation of iron homoeostasis, anti-microbial and anti-viral functions, and protection against cancer development. Lactoperoxidase, another protein with antibacterial function, is present in donkey milk, but in very low quantities (0.11 mg/L). β-lactoglobulin content in donkey milk is 3.75 g/L—this protein is able to bind and transport several hydrophobic molecules. Donkey milk’s α-lactalbumin concentration is 1.8 g/L, very close to that of human milk. α-lactalbumin shows antiviral, antitumor, and anti-stress properties. Therefore, donkey milk can be considered as a set of nutraceuticals properties and a beverage suitable, not only for the growing infants, but for all ages, especially for convalescents and for the elderly.

In this review, we summarize the latest evidence demonstrating that the shape and feel of the glassware (and other receptacles) that we drink from can influence our perception of the taste/flavour of the contents. Such results, traditionally obtained in the world of wine, have often been interpreted in terms of changes in physico-chemical properties (resulting from the retention, or release, of specific volatile aromatic molecules), or the differing ways in which the shape of the glassware funnels the flow of the liquid across the tongue. It is, however, not always clear that any such physico-chemical differences do, in fact, lead to perceptible differences. Others, meanwhile, have stressed the importance of cultural factors, and the perceived appropriateness, or congruency, of the receptacle to the drink, based on prior experience. Here, though, we argue that there is also a much more fundamental association at work between shape properties and taste/flavour. In particular, the suggestion is made that the shape properties of the drinking receptacle (e.g., whether it be more rounded or angular)—regardless of whether the receptacle is seen, felt, or both—can prime certain expectations in the mind of the drinker. And, based on the theory of crossmodal correspondence, this priming is thought to accentuate certain aspects of the tasting experience, likely as a result of a taster’s attention being focused on the attributes that have been subtly primed.

Milk whey—commonly known as cheese whey—is a by-product of cheese or casein in the dairy industry and contains usually high levels of lactose, low levels of nitrogenous compounds, protein, salts, lactic acid and small amounts of vitamins and minerals. Milk whey contains several unique components like immunoglobulins (Igs), lactoferrin (Lf), lactoperoxidase (Lp), glycomacropeptide (GMP) and sphingolipids that possess some important antimicrobial and antiviral properties. Some whey components possess anticancer properties such as sphingomyelin, which have the potential to inhibit colon cancer. Immunoglobulin-G (IgGs), Lp and Lf concentrated from whey participates in host immunity. IgGs binds with bacterial toxins and lowers the bacterial load in the large bowel. There are some whey-derived carbohydrate components that possess prebiotic activity. Lactose support lactic acid bacteria (such as Bifidobacteria and Lactobacilli). Stallic acids, an oligosaccharide in whey, are typically attached to proteins, and possess prebiotic properties. The uniqueness of whey proteins is due to their ability to boost the level of glutathione (GSH) in various tissues and also to optimize various processes of the immune system. The role of GSH is very critical as it protects the cells against free radical damage, infections, toxins, pollution and UV exposure. Overall GSH acts as a centerpiece of the body’s antioxidant defense system. It has been widely observed that individuals suffering from cancer, HIV, chronic fatigue syndrome and many other immune-compromising conditions have very poor levels of glutathione. The sulphur-containing amino-acids (cysteine and methionine) are also found in high levels in whey protein. Thus, the present review will focus on the therapeutic potential of milk whey such as antibiotic, anti-cancer, anti-toxin, immune-enhancer, prebiotic property etc. Full article

This work provides an updated picture of communication strategies developed to improve healthy dietary habits in schoolchildren, with a focus on the importance of milk consumption. The paper has investigated two main areas: the definition of the main orientations and key points of research approach relative to the communication methods, with special attention to multiple strategies and the identification of their peculiarities to increase daily milk consumption. The school environment is considered as a unique environment to help increase the adoption of a correct dietary habit and lifestyle; it increases physical activity by facilitating the flow of health-related information. In this regard, several studies have highlighted the importance and effectiveness of school-based interventions on a large-scale, also considering multiple contexts, early interventions as well as the involvement of teachers, students and families. The effective actions range from interventions on prices and the availability of desirable and undesirable foods to educational programmes that improve food knowledge and the choices of students and/or their parents. From the nutritional point of view, milk is an important component of a well-balanced diet—especially for children—because it contains essential nutrients. It is a substantial contributor to the daily energy intake; however, its consumption often declines with aging and becomes insufficient. Therefore, developing strategies to increase its consumption is an important objective to reach. Full article

Pomegranate Juice (PJ) and Green Tea (GT) products have increased in popularity because of their beneficial health properties. Consumers look for healthier beverages, and rely on labels, claims, and product packaging when choosing a product. The objectives of this study were to determine (1) the sensory profiles and acceptance of PJ and GT blends; (2) whether additional information would have an effect on consumer acceptance; and (3) the total phenolic content (TPC) of the samples. Six PJ and GT blends were evaluated by a descriptive panel in order to explore sensory differences in flavor characteristics. A consumer panel (n = 100) evaluated the samples before and after beneficial health information about the samples was provided to them. The blends that were higher in tea concentration were higher in Green and GT-like flavors, and lower in berry, beet, floral, sweetness, and cherry flavors. The overall liking scores of all of the samples increased after the information was provided to the consumers. The sample highest in PJ and lowest in GT blend was liked the most. In addition, as the samples increased in PJ, the TPC content increased. These results may be of interest to the beverage industry, providing information of consumer liking of beverage blends, and how information on health related claims affects consumer acceptance.

Microorganisms play an important role in the conversion of grape juice into wine. Yeasts belonging the genus Saccharomyces are mainly responsible for the production of ethanol, but members of other genera are known as producers of off-flavors, e.g., volatile phenols. Lactic acid and acetic acid bacteria also occur regularly in must and wine. They are mostly undesirable due to their capacity to produce wine-spoiling compounds (acetic acid, biogenic amines, N-heterocycles, diacetyl, etc.). In conventional winemaking, additions of sulfite or lysozyme are used to inhibit growth of spoilage microorganisms. However, there is increasing concern about the health risks connected with these enological additives and high interest in finding alternatives. Phenols are naturally occurring compounds in grapes and wine and are well known for their antimicrobial and health-promoting activities. In this study, we tested a selection of phenolic compounds for their effect on growth and viability of wine-associated yeasts and bacteria. Our investigations confirmed the antimicrobial activities of ferulic acid and resveratrol described in previous studies. In addition, we found syringaldehyde highly efficient against wine-spoiling bacteria at concentrations of 250–1000 µg/mL. The promising bioactive activities of this aromatic aldehyde and its potential for winemaking deserves further research. Full article

The conducting polymer PEDOT (poly-3,4-ethylenedioxythiophene) has been polymerized onto 3 mm and 10 µm electrodes from a propylene carbonate solution. The electrodes have then been tested in a Chardonnay wine, including dilutions in a model wine solution, with comparisons made to scans with a glassy carbon electrode. A well-defined oxidation peak was obtained for the white wine at PEDOT in the 400 to 450 mV (Ag/AgCl) range, where peaks were also obtained for the representative phenolics caffeic acid and catechin. The voltammetry at PEDOT was typical of a surface-confined process. Significant preconcentration, leading to an increased current response, was noted over a period of 20 min of holding time. Extensive PEDOT growth was observed in the microelectrode case, leading to current densities for the oxidation of caffeic acid over 1000 times greater than those observed at the macroelectrode, matching the high surface area and fractal-type growth observed in SEM images.

A product of easy preparation and high added value, soluble/instant coffee is obtained by drying the aqueous extract of roasted coffee and presents a high amount of bioactive compounds. The aim of the study was to evaluate the antioxidant activity of 33 Brazilian commercial soluble coffees considering the radical scavenging activity (via the ABTS method) and the reducing capacity (via the Folin–Ciocalteu method). Soluble coffees of several brands and types (regular, gourmet, and decaffeinated), subjected to different drying processes (agglomeration, atomization, and freeze-drying) (n = 85), were evaluated. In general, regular and decaffeinated soluble coffees presented high antioxidant activity. The reducing capacity ranged from 9.9 to 15.4 g of gallic acid per 100 g, while the radical scavenging activity ranged from 20.4 to 37.0 g of Trolox per 100 g. Good repeatability—with coefficients of variation of 2.4% for Folin–Ciocalteu and of 5.2% for ABTS—and high correlations between the values of antioxidant activity obtained by both methods (r = 0.66) were observed. Gourmet coffees presented less antioxidant activity compared to the regular samples. No correlation was verified between drying processes and antioxidant activity. Full article

In recent years, a number of commentators have suggested that the use of finings to clarify beer can impair the flavour, because of the removal of key volatile aromatic molecules from the drink. However, are such claims necessarily correct? Unaware of any previous attempt to address this question empirically, we conducted both a blind and a sighted taste test. The test made use of two beers from the same batch, one made using finings and the other made without. In neither experiment did the use of finings affect flavour or liking ratings amongst the social drinkers (N = 235) tested. Thus, the present results clearly suggest that the use of finings does not necessarily impact either the sensory-discriminative or hedonic ratings of beer, despite its influence on the clarity of the finished product.

There is a wide range of information available on by-product disposal methods used by large national breweries. However, little information is available on the methods of by-product disposal used by craft breweries. An investigation was carried out in which 200+ British craft brewers were contacted, of which 90 craft brewers provided basic information about their brewery operations and by-product disposal. Representatives of eleven breweries were interviewed to provide an in-depth case study of their by-product disposal methods. The research found that urban craft brewers use a wider range of disposal methods compared to rural craft brewers; urban brewers dispose of more waste through sewage and landfill, as well as using external companies, such as bio-recycling and anaerobic digester plants, whereas rural brewers have relationships with farmers who dispose of the by-products in various ways. Craft brewers tend to have a direct relationship with the by-product users. Even though they do not have all disposal options available to them which the large industrial breweries have, due to their small scale of by-product production, craft brewers appear to find alternative means of sustainability.

Beer lovers all over the world like to get their drink with a certain volume of stabile foam, which mainly depends on the beer style. However, sometimes this foam comes in form of a sudden, eruptive, and uncontrolled over-foaming (gushing) of beer. Gushing occurs after the bottle has been opened, without previously being treated inappropriately (exposure to high temperatures, shaking, or any other kind of agitation). According to recent scientific and professional literature, gushing may be induced by many factors, but fungal proteins are directly connected to this phenomenon. Gushing caused by fungal proteins—hydrophobins—is called primary gushing, and depends solely on raw material quality. Other reasons for extensive foaming after the bottle has been opened can be of chemical or technological nature in the course of the brewing process. This is called secondary gushing, which can be influenced and reduced by applying good manufacturing practice protocols. Full article

In this study, an innovative emulsion made from soybean and navy bean blends of different proportionalities was developed. In addition, two processing methods were used: traditional cooking and jet-cooking. The physical attributes and storage stability were measured and compared. This study found that the high content of starch and fiber in navy bean flour contributes to the increase in viscosity of the emulsions, at both room and refrigeration temperatures, as the proportion of navy bean flour in the blends increased. The steam jet-cooked emulsions with higher soybean content has better shelf life stability, smaller particle size, higher fat, lower starch, and lower viscosity, whereas the traditional kettle cooking method is better in reducing anti-nutritional components. No significant difference was found between the two cooking methods in terms of nutritional contents in the emulsions, such as protein, crude fat, and total starch. The traditional kettle cooking, with its longer cooking time, seems to reduce more trypsin inhibitor in the emulsions than those prepared with the steam jet-cooking. This exploratory study is the first to report soybean–navy bean beverage prototypes having desirable nutritional value and the potential for functional beverage market. Full article
