DocumentFish and their by-products 2016
Also available in:
No results found.Fish is a unique source of micro-nutrients. However, many parts of larger fish, such as the head and the bones, are discarded during fish processing despite the high levels of nutrients, and particularly micro- nutrients found in these parts. Thus the promotion and use of fish byproducts to create low-cost, high-quality food could help reduce malnutrition. This practice illustrates the nutritional benefits of incorporating fish byproducts in the diet and suggests recipes to guide their preparation. -
Book (series)Production of high-value products from the by-products of aquatic food processing 2024
Also available in:
No results found.The processing of aquatic food generates substantial by-products, including animal heads, skins, bones, scales, visceral organs and shells, etc., which can constitute between 30 percent and 70 percent of the whole body of aquatic organisms. These by-products retain numerous bioactive molecules suitable for extraction and application in the nutraceutical, functional food, pharmaceutical, biomedical, cosmetic and material industries, and have the potential to yield high-value products. The transition from aquatic food waste to high-value products presents multiple benefits, including: (i) enhanced human nutrition and health through nutrient and bioactive component provision; (ii) mitigation of environmental pollution by reducing waste; and (iii) improved economic returns because aquatic food waste is transformed into high-value products rather than low-value animal feeds or fertilizers. This guide presents strategic and technical insights by outlining key principles for producing high-value items, including collagen, gelatine, bioactive peptides, chitin, chitosan, chondroitin sulphate, fish leather and fish oil, from the by-products of aquatic food processing. -
BookletEthiopia | Availability and utilization of agroindustrial by-products as animal feed | 2018 2019
Also available in:
No results found.One of the major constraints for the very low production and productivity of livestock in Ethiopia is the poor quality and inadequate quantity of available feed. Agro-industrial by-products (AIBPs) can play an important role in meeting the widely prevalent feed shortage in the country. The AIBPs are usually less fibrous, rich in energy and/or protein contents. They have high digestibility and energy values compared with other classes of feed resources. The major AIBPs produced in Ethiopia include by-products from flour millings, sugar factories, edible oil processing factories, breweries, and abattoirs. These by-products play a vital role in the feeding of livestock mainly in urban and peri-urban livestock systems. The spatial and temporal availability of AIBPs in different parts of Ethiopia has not been quantified. Information on the utilization of such resources is also scanty. Data on availability of these resources is important for developing and using appropriate feeding strategies, improving livestock production and productivity, enhancing the efficiency of AIBPs utilization, decreasing burden on the environment and promoting technologies that further circular economy. This study was aimed at assessing the spatial and temporal availability of major AIBPs and their use as livestock feed. Information on storage and transport of these by-products has also been recorded with the aim to identify ‘hotspots’ at which the wastage takes place, and to suggest ways to reduce it.
