The rapid development in the food supply chain has led to increased interest for quality in the food sector. In the last two decades, the human health and food safety have become essential. Health problems are highly related to diet and nutritional habits. The connection between nutrition and the development of various health problems is even more noticeable when close attention is given to every age group. Regarding the chemical composition of foods, a large number of bioactive compounds present in plants, fruits, vegetables, dairy products, meat, and fish are currently known. Bioactive compounds from food play an important role in prevention of illnesses. Covering essential aspects of health benefits of foods, the present chapter underlies without being exhaustive, the potential of valuable compounds such as soy isoflavones, phytochemicals, polysaccharides, probiotics, prebiotics, lipids, and marine proteins to be used as an effective prevention strategy for developing various human cancers, cardiovascular diseases, diabetes, and metabolic disorders.

“…Fish muscle and tissues are composed of structures like myofibrillar (Hayes & Flower, 2013) and collagen proteins (Xu et al, 2015). Myofibrillar proteins occupy the main components which are crucial for maintaining the integrity of texture and mechanical properties of the muscle (Wang, Wartinez, & Olsen, 2009).…”

We examined the influence of blood deposition on flesh quality of ordinary muscle in yellowtail. This study compared the flesh quality changes in upper and under‐sides of yellowtails killed by two different methods: spinal‐cord destruction (SCD) with blood removal and suffocation in air without blood removal (SA). The under‐sides of the SA group showed the highest values for a*, cathepsin B and B + L activities, the lowest value in breaking strength and the greatest degradation of myosin heavy chain (MHC) among the four groups. However, the values of the SCD‐upper group indicated the best flesh quality. In addition, the white blood cells presented the highest cathepsin B and B + L activities among the blood components. These results indicate that blood has the tendency to deposit downward in accordance with the direction of placement. This phenomenon influences the distribution of white blood cells which contain enzymes that accelerate the deterioration of flesh quality. The texture of fish muscle is an important part of the flesh quality. In captured fishery (purse‐seine fishery and dragnet fishery), it is impossible to immediately and completely remove blood. Therefore, suffocation in air is the common method after the fish is caught. The commercial value of fish is decreased and the price varies greatly when these fish enter market circulation. In our study, we examined the influence of blood deposition on the flesh quality of yellowtail during storage. The degradation of structural proteins accelerated in the deposited blood which contain proteases. The movement and deposition of blood caused the difference of quality on both sides, which seriously affected the quality of fish during preservation. Our study has some theoretical guidance for muscle softening and give a better understanding of the adverse effect of blood during preservation.

“…As alternatives, other low‐cost protein sources (e.g. whey, fish and shellfish by‐products) and marine microalgae have been tested to produce bioactive peptides (Hayes & Flower, ; Wu et al ., ). Among these substitutes, microalgae offer higher advantages of sustainability due to the non‐reliance on wild and easily depleted populations stocks (Barsanti & Gualtieri, ).…”

Several bioactive compounds from microalgae have demonstrated diverse biological activities with positive effects on human health. However, the potential of bioactive peptides as functional foods is still undervalued. Therefore, the exploration of microalgae strains as sources of bioactive peptides could reveal strong and unique bioactivities, especially when these marine sources have never been explored before. For this aim, protein extracts from six indigenous marine diatoms were subjected to enzymatic hydrolysis using four proteases (flavourzyme, pepsin, papain and trypsin). The hydrolysates were then tested for angiotensin converting enzyme (ACE)-inhibitory, antioxidant and antihypertensive properties. Results showed that papain hydrolysates from all microalgae strains exhibited strong ACE-inhibitory activities and antioxidant properties. In particular, protein hydrolysates from Bellerochea malleus were found to reduce blood pressure properties of 17 mmHg after 5 days of oral administration to SHR animals. These results revealed the potential of bioactive peptides from indigenous marine diatoms for use as functional foods or nutraceuticals.
