Special Issue Information

Dear Colleagues,

The first edition (https://www.mdpi.com/journal/foods/special_issues/Food_Bioactives) of this Special Issue was incredibly successful. We would like to express our gratitude to everyone involved, and especially to numerous high-profile scientists for their support. The topic of the “Application of Emerging Nonthermal Technologies in the Food Industry” continues to play a pivotal role today, and it is for this reason that we are launching a second edition, which we hope will be equally as successful.

In the past, thermal processing technologies were widely used to sterilize and enhance the flavor of food. However, some toxic substances such as acrylamide and furan are easily released during thermal processing, and these are considered to be carcinogens by the WHO. Recently, emerging nonthermal processing technologies, such as high-pressure processing, radiation, pulsed electric fields, pulsed light, and cold plasma, have been found to ensure the quality and freshness of foods and avoid the generation of carcinogens. In addition, nonthermal technologies have been used to extract active substances from fruit, vegetables, and industrial crop residues, which facilitate the utilization of food and its byproducts. Current studies focus on combination treatment which may be a more effective processing technique for the food industry. Clarifying the mechanisms, optimizing the processes, producing industrial-scale equipment, analyzing potential risks, and designing safety rules will be essential in promoting future nonthermal processing technologies.

A novel storage technique that combines the low-frequency electric field (LFEF) and ice temperature was used to extend the shelf life of Pacific white shrimp (Penaeus vannamei). The study investigated the effect of LFEF treatment on the quality and microbial composition of Penaeus vannamei during storage at ice temperature. The results showed that the LFEF treatment significantly extended the shelf life of shrimp during storage at ice temperature. The total volatile base nitrogen (TVB-N) and pH of samples increased over time, while the total viable count (TVC) showed a trend of first decreasing and then increasing. Obviously, shrimp samples treated with LFEF had a lower pH, TVB-N and TVC values than the untreated samples (p < 0.05) at the middle and late stages of storage. LFEF treatment increased the diversity and altered the composition of the microbial communities in Penaeus vannamei. Additionally, the treatment led to a decrease in the relative abundance of dominant spoilage bacteria, including Aliivibrio, Photobacterium and Moritella, in Penaeus vannamei stored at ice temperature for 11 days. Furthermore, correlation analysis indicated that TVB-N and pH had a significant and positive correlation with Pseudoalteromonas, suggesting that Pseudoalteromonas had a greater impact on shrimp quality. This study supports the practical application of accelerated low-frequency electric field-assisted shrimp preservation as an effective means of maintaining shrimp meat quality. Full article
