Title : Interactions of carotenoids with different nutrients in aquatic oranisms
Abstract:
Carotenoids play key role in colouration, growth, metabolism, health and reproduction, other than having provitamin A and antioxidant activity in different animals including aquatic organisms. Although some bacteria, algae, fungi and plants can biosynthesize them, animals cannot synthesize denovo. Consequently, they must obtain them from their dietary sources. However, carotenoids bioavailability from food is modulated by several factors like food matrix, interactions with different nutrients, composition of carotenoids, food preparation procedures, metabolic activity of different organisms etc.In this review,the interactions of carotenoids with various factors in respect of aquatic organisms’ health, and physiology have been discussed.
Audience Take Away Notes:
- Health and physiology and colouration of Aquatic Organism: Carotenoids have beneficial effects on growth and physiology of Aquatic organisms. Through aquatic food chain, different organisms specifically ornamental fish can obtain them for vibrant skin colouration, food fish and prawn for flesh colouration. Again through aquatic food chain of edible fish and prawn and other aquatic organisms, the consumers can get various beneficial effects of natural carotenoids on physiology and good health. Because carotenoids not only have advantageous effect as antioxidant, anticancer and provitaminA mediator, it lowers the risk of cardiovascular and degenerative disease, perk up cognitive and neuromotor health.
- Bioavailability of Carotenoids and increasing the efficiency of carotenoid activity: However, their bioavailability differs and modulated by several factors which are discussed in this review.
- This will help the faculty members, researcher and fish culturist during farm made feed preparation for aquatic organisms giving due attention to the factors interfere with bioavailability of carotenoids. It will help to explore different carotenoid resources and do work on application of different carotenoids as food additive and neutraceuticals.
