Special Issue Information

Dear Colleagues,

This Special Issue will explore the intersection between tradition and innovation in food science, focusing on the microbiological, technological, and functional aspects of traditional and innovative foods. Topics for submission include, but are not limited to, the microbial ecology of foods and the role of lactic acid bacteria, non-Saccharomyces yeasts, moulds, and Saccharomyces cerevisiae in shaping the sensory profile and safety of fermented products. The convergence of artisanal knowledge and modern biotechnology will  be examined across a range of products, including fermented vegetables, dairy, wine, beer, mead, and table olives. We welcome contributions in the fields of food microbiology, food safety, and dairy science, especially studies on microbial dynamics, fermentation processes, and functional food development. Research on traditional foods and beverages is also encouraged, with emphasis on their cultural relevance and potential for innovation. This Special Issue aims to bridge traditional practices and scientific progress, highlighting how microbial communities and fermentation technologies can enhance food quality, safety, and nutritional value.

Donkey Milk Quality and Safety: Challenges of Using the ISO 11816-1 ALP Method for Pasteurization Verification

Abstract
Donkey milk is valued for its similarity to human milk, low allergenicity, and high nutraceutical content, particularly lysozyme. As for milk from other species, donkey milk requires pasteurization for commercial sale. The ISO 11816-1 alkaline phosphatase (ALP) method, developed for cow’s milk, is [...] Read more.
Donkey milk is valued for its similarity to human milk, low allergenicity, and high nutraceutical content, particularly lysozyme. As for milk from other species, donkey milk requires pasteurization for commercial sale. The ISO 11816-1 alkaline phosphatase (ALP) method, developed for cow’s milk, is currently used to verify pasteurization in donkey milk. This study evaluated whether the method distinguishes compliant from non-compliant treatments and investigated associations of native and residual ALP with chemical and physiological parameters. Milk from 14 Ragusano donkeys was sampled three times at three-month intervals (42 samples) and analyzed for chemical and physiological composition, lysozyme, and total antioxidant capacity. Samples underwent compliant and non-compliant heat treatments, and ALP was determined. All residual ALP values, even for non-compliant treatments, were well below the bovine ISO threshold, and non-compliant treatments were not fully distinguished, precluding this method as a suitable approach. Pasteurization at 76 °C × 15 s is suggested, with an explorative and provisional threshold of 61 mU/L to achieve 100% specificity while preserving nutraceutical components. Considering a 9% analysis uncertainty at 95% confidence, ALP values below 50 mU/L are fully negative, with 97% of compliant samples below this value. Native ALP was highly variable (1758–6086 mU/L) and depended on physiological parameters and lactose, but not fat. Validation on larger datasets and across other breeds is required. Full article

Due to the allergenicity of soy protein, this study aimed to develop a hypoallergenic, dysphagia-friendly matrix using pea protein isolate. We investigated the effects of three hydrocolloid thickeners—xanthan gum (XG), guar gum (G), and carrageenan (C)—at various concentrations on the matrices’ rheological properties, textural characteristics, and dysphagia diet classification. The unthickened pea protein base was unstable, exhibiting rapid phase separation and low viscosity, unsuitable for dysphagia diets. The addition of XG (0.4–0.6 g), G (0.5–1.0 g), and C (0.8–1.2 g) successfully produced food matrices meeting the slightly, mildly, and moderately thick levels of the Japanese Society of Dysphagia Rehabilitation (JSDR) framework. However, discrepancies were noted between instrumental viscosity and syringe flow test classifications. Rheological analysis revealed that XG samples were in elastic (G′ > G″) domain in the linear viscoelastic region (LVR) and exhibited shear-thinning behavior. In contrast, G and C samples were in viscous (G″ > G′) domain. Frequency sweeps characterize XG samples as weak gels, G samples as dilute polymer solutions, and C samples as gel-like structures. Texture profile analysis further showed that xanthan gum imparted the highest firmness and thickness, whereas guar gum provided the best flowability. Full article

This study provides a comprehensive characterization of the microbiological, chemical, and sensory profiles of Sicilian Canestrato Fresco (SCF) cheese, a traditional agri-food product (TAP) made from raw cow’s milk using artisanal methods and typically consumed after 20 d of ripening. Plate count analyses confirmed high levels of mesophilic lactic acid bacteria (LAB) exceeding 108 CFU/g. Both rod- and coccus-shaped LAB populations were present at these elevated levels. Pathogens such as Listeria monocytogenes and Salmonella spp. were not detected, although potential contaminants including Enterobacteriaceae, total coliforms, and Escherichia coli were detected at levels of 1.0–3.5 log CFU/g. High-throughput sequencing confirmed LAB as the dominant taxa, comprising the majority of the bacterial community, which accounted for 78.12% to 99.63% of the total relative abundance (RA) across all cheese samples. The fatty acid profile was typical of cow’s milk cheeses, with long-chain fatty acids (C15–C18) representing ~75% of the total, followed by medium- (~17%) and short-chain (<8%) fatty acids. Volatile organic compound analysis showed free fatty acids as the most abundant class, followed by esters, alcohols, ketones, and aldehydes. These findings highlight the role of traditional practices in preserving the sensory and chemical identity of SCF cheese. However, the presence of hygiene indicators suggests a need for improving sanitary measures along the production chain. Future research should explore the impact of targeted microbial management and packaging conditions to enhance both safety and product standardization without compromising artisanal traits.
