Summary
The proposed technology is used for the production of high functional ingredients from fish by-products. It can be applied to a) underutilized fish, b) fish processing wastes such as frames, deboning waste, etc.), c) toxic mussels d) fish discards and e) other fish species. The resulting press juice powder can be used as a strong antioxidant, natural additive to various food formulations and/or supplements. The Protein isolates can be used as additives in food technology applications to improve functionality of the final product. They can also be used to produce surimi like products. Both products have potential in functional food industry and in nutraceuticals, since they possess health beneficiary components from natural sources.
Technology Description
|
The proposed process used for the production of high functional ingredients from fish by-products, consists of the following steps: Step 1. Centrifugation of comminuted fish discards and/or non-marketable fish. The obtained press juice is then filtered, and can be either spray dried or freeze dried |
Step 2. Apply acid or alkali aided solubilization to fish processing wastes and/or marine discards to recover functional proteins.
Main advantages
Utilization of fish processing wastes, low lipid products, functional proteins, press juice, antioxidants, easy set up
Stage of development
The proposed technology has been validated in the lab (TRL4)
Challenge and needs
|
a) evaluate and enhance if necessary storage stability of the antioxidative press juice powder and protein isolates b) improve color of protein isolates and enhance their oxidative stability |
c) complete compositional analysis of the two products to point out their health beneficiary components and determine bioavailability of these components
Intellectual property
A prior art research is under development
Potential markets and targets
The proposed technology can be adopted by the fish processing industry, ingredients manufacturers, the food industry and nutraceutical companies as well. Speaking of nutraceuticals the respective global market is projected to reach USD 578.23 billion by 2025, according to a new report by Grand View Research, Inc. Growing awareness regarding the consumption of healthy foods has resulted in increased demand for nutraceuticals. An increased focus on the ingredients used for manufacturing nutraceuticals has been weatnessed specifically. The demand for natural products is expected to grow at a rapid pace over the next eight years as consumers perceive these products to be healthier and more effective as compared to synthetic products.
