Special Issue Information

Dear Colleagues,

In recent years, the demand for specialty products based on new ingredients, functional foods, alternative protein sources, gut health, and bioactive formulations have continuously increased. The production of these products requires the application of advanced and innovative processes and technologies. 

This Special Issue is focused on the advancements and applications of various processes used in the food industry and preservation technologies. It concerns new research and information on the use of innovative and non-traditional processing and preservation technologies during food production, processing, and transportation.

Therefore, this Special Issue will include original scientific developments and new perspectives in the following areas: (i) applications of various processes and preservation technologies in food production, (ii) novel and non-traditional methods for the transformation of food products, (iii) innovation for the production of functional foods and their storage, and (iiii) new methods and knowledge for shelf life extension, food safety, and the valorization of food processing by-products as well as energy efficiency. These topics are indicative and research is not strictly limited to them.

We invite you to contribute review articles, short communications, and full-size research papers to this Special Issue.

Dr. Nikolay D. Menkov
Guest Editor

The process of rose oil distillation generates a huge amount of waste byproducts, which often remain unused, and poses serious environmental challenges; at the same time, they contain polyphenols with antioxidant, antimicrobial, and therapeutic properties. The purpose of this work is to investigate the possible application of ultrafiltration using three polyacrylonitrile membranes (molecular weight cut-off 1 kDa, 10 kDa, and 25 kDa) to recover the total polyphenolic compounds, phenolic acids, and flavonoids from rose wastewater. The permeate flux, energy demand, contents of total polyphenolic compounds, phenolic acids, and flavonoid phenolic compounds were determined during ultrafiltration at a volume reduction ratio of 2, 4, 6 and 8, and the rejections and concentration factors were established. The optimal operation conditions for permeate flux, energy demand, rejection, concentration factor, and antioxidant activity were established at a volume reduction ratio of 8, transmembrane pressure of 0.5 MPa, and 1 kDa membrane. These working conditions will be used in our future investigations to obtain extrudates from rice semolina enriched with ultrafiltered rose wastewater. Protocatechuic and vanillic acid, determined by HPLC, increased in the retentate when the 1 kDa membrane was used, while gallic acid, catechin, p-coumaric acid, rutin, hesperidin, and rosmarinic acid decreased.

In the present study, the content of selected micro- and macrominerals in conventional and specialist infant formulas (IFs) available on the Polish market was assessed and compared with breast milk from different periods of lactation. The content of minerals was assessed against established standards, compared to label guidelines, and the estimated coverage of daily requirements for selected minerals among infants. The study material consisted of fourteen types of initial, follow-on, and specialist IFs. Minerals—Na, K, Ca, Mg, Fe, Zn, Cu, and Mn were determined by the atomic absorption spectroscopy (AAS) method and P—by colorimetric method. The specialist formula S1 stood out in terms of Ca, Mg, and Mn, and S6 in terms of Na and K compared to other IFs (p < 0.05). Human milk contained lower contents of each element relative to all infant formulas. Regarding the European Commission’s recommendations, most types of IFs met standards for mineral content. In 12 IFs, the marked Fe content was lower than that declared by the manufacturer, and the difference ranged from 5 to more than 50%. All of the initial and five specialist IFs covered the need for all minerals among infants, while follow-on reported coverage lower than standards for Mg, Na, K, Fe, and Mn. Infant foods should be strictly controlled, and periodic checks on the determination of levels of selected ingredients in IFs are recommended to obtain products that resemble human food to the highest possible degree.

The food industry mostly utilises thermal processing technologies to enhance the food safety and shelf life by inactivating enzymes, pathogens, and spores. However, there is a shift towards consumer preference for minimally processed foods due to health concerns and the limitations of the conventional thermal processing methods. Thus, the food industry has recently increased the utilisation of non-thermal technologies for food processing and preservation in the production of foods while maintaining the nutritional and sensory qualities of the food. Non-thermal approaches including a Pulsed Electric Field (PEF), High-Pressure Processing (HPP), Ionising Radiation (IOR), Ultraviolet (UV) light, Pulsed Light (PL), and Cold plasma (CP) are increasingly being employed for food preservation, especially for heat-sensitive foods, as they enable microbial inactivation with minimal or no thermal application and less degradation of bioactive constituents of foods. As opposed to conventional thermal technologies that may compromise the food quality, non-thermal preservation processes retain the texture, taste, and rheological properties, therefore presenting an invaluable option in the food chain system. Moreover, non-thermal food processing approaches are becoming well-established within the food sector as they can be utilised for a wide range of food items. This paper provides a critical review of the industrial applications, mechanisms of action, and efficiency of major non-thermal food processing technologies. In addition, it also addresses their impact on the food quality, microstructure, and rheology, while exploring their limitations. Although these technologies are of great value in preserving the shelf life and food integrity, high upfront investment costs continue to discourage large-scale adoption. However, with the growing demand for fresh and minimally processed foods, the operational costs for these technologies are expected to become more accessible, promoting their widespread adoption in the industry.
