Special Issue Information

Dear Colleagues,

The marine environment is a relative storehouse holding a largely untapped source of functional ingredients that can be applied to explore functional food. Numerous marine-based compounds with diverse biological activities have been considered significant parts of a balanced diet. For example, bioactive peptides isolated from marine fish protein hydrolysates as well as algal fucans, galactans and alginates, have been shown to possess anticoagulant, anticancer and hypocholesterolemic activities. Marine fish oils and bacteria are excellent sources of omega-3 fatty acids, while crustaceans and seaweed contain abundant and powerful antioxidants and bacteriostats. Additionally, some studies have demonstrated that these functional ingredients could adjust intestinal flora and affect human health. However, the relationship between marine food nutrition and health still causes lots of interest from researchers and consumers. It still requires numerous research works to promote the development of new marine functional food and a deep investigation into the relationship between the functional properties and structural characteristics of ingredients. Exploring the potential use of marine-derived compounds as functional food ingredients for health maintenance and the prevention of chronic diseases can help better understand the marine functional food industry. Therefore, we are launching this Special Issue where all studies related to these topics are welcome.

Aging is characterized by a decline in social behavior and cognitive functions leading to a decrease in life quality. In a previous study, we show that a fish hydrolysate supplementation prevents age-related decline in spatial short-term memory and long-term memory and anxiety-like behavior and improves the stress response in aged mice. The aim of this study was to determine the effects of a fish hydrolysate enriched with EPA/DHA or not on the cognitive ability and social interaction during aging and the biological mechanisms involved. We showed for the first time that a fish hydrolysate enriched with EPA/DHA or not improved memory performance and preference for social novelty that were diminished by aging. These changes were associated with the modulation of the gut microbiota, normalization of corticosterone, and modulation of the expression of genes involved in the mitochondrial respiratory chain, circadian clock, neuroprotection, and antioxidant activity. Thus, these changes may contribute to the observed improvements in social behavior and memory and reinforced the innovative character of fish hydrolysate in the prevention of age-related impairments.

Abstract
Phosphorylated fish gelatin (PFG) exhibited preferable physical and chemical properties than fish gelatin (FG) in our previous study. To investigate the application values of PFG, the effects of different ratios (2:1, 1:1 and 1:2) of FG(PFG)/κ carrageenan (κC) on the quality of jelly [...] Read more.
Phosphorylated fish gelatin (PFG) exhibited preferable physical and chemical properties than fish gelatin (FG) in our previous study. To investigate the application values of PFG, the effects of different ratios (2:1, 1:1 and 1:2) of FG(PFG)/κ carrageenan (κC) on the quality of jelly gels (JGs) were investigated. The sensory quality of PFG:κC (1:2)/FG:κC (1:2) was found to be superior based on sensory evaluations, which was also verified with the results for texture, rheology, etc. Moreover, the structural changes in JGs were related to the introduction of phosphoric acid groups into the molecular chain of gelatin and the protein–polysaccharide interactions. According to the storage results, PFG jelly had better storage quality, higher hardness and chewiness values than those of FG jelly. High-throughput sequencing of JG microbial analysis showed that the addition of PFG changed the amount of microorganisms, microbial species abundance and the microbial composition of JGs, which were also closely related to the storage quality of JGs. In conclusion, the applications of PFG have promising potential to improve the quality of confectionery. Full article
