With the development of fish culture and feed industry, it is very necessary to add attractants to bait. Food attractants, also known as palatable additives, belong to non-nutritional additives, including umami, sour, salty, fragrant, sweetening and spicy.
Adding attractant to feed cultured fish can effectively promote fish to eat and increase food intake, thus improving the utilization efficiency of feed; Promote fish's preference for bait, reduce bait coefficient, reduce water pollution, shorten production cycle and improve fish farming efficiency;
Using attractants can make fish make better use of raw materials such as plant protein that they don't like, which is conducive to developing new feed resources and reducing feed costs.
Extended data:
The object of feeding attractants is animals. Different domestic animals and poultry not only have different taste preferences, but also have different physiological thresholds for sensory sensitivity to a certain taste. Therefore, when configuring and selecting applications, we must follow the effectiveness standards, physical and chemical standards and security standards.
Compared with other additives, food attractants are unique in that they need certain physical and chemical stability, namely:
1, the feed flavoring agent should withstand the high temperature damage in the preparation process, so as to avoid unpleasant fragrance and smell in the feed.
2. Compatibility: Its physical and chemical compatibility with feed ingredients has a great influence on its efficacy. Copper, potassium, urea, choline oxide, fish meal, granular adhesive, preservatives and drugs have adverse effects on the efficacy and quality of attractants.
