Ultra-low starch micropterus salmoides expanded feed and preparation method thereof

Abstract

The invention relates to ultra-low starch micropterus salmoides expanded feed which comprises, by weight, 25-28 parts of Japanese-grade fish meal, 18-30 parts of tilapia meal, 5-15 parts of krill meal, 5-9 parts of fermented soybean meal, 3-7 parts of dried porcine soluble, 5-9 parts of strong flour, 1-2 parts of monocalcium phosphate, 5-8 parts of soybean phospholipid oil, 2-5 parts of soybean oil, 2-3 parts of squid visceral ointment extracts, 1-4 parts of fish dissolved pulp, 1.5-2.5 parts of micropterus salmoides vitamin premixed materials, 2.5-3.5 parts of micropterus salmoides mineral substance and other premixed materials and 0.2-0.3 part of emulsifying agents. Starch content of the micropterus salmoides expanded feed is ultra-low (starch is only from materials such as the soybean meal and flour, additional adding is omitted, and the content of the starch is ultra-low), harm to micropterus salmoides health is low, the feed can completely replace iced fresh trash fishes, so thatenvironmental pollution caused by iced fresh materials is reduced, and micropterus salmoides food safety risks are reduced.

Description

technical field [0001] The invention relates to a California perch feed, in particular to an ultra-low starch California perch extruded feed and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the demand for fresh aquatic products is increasing. California sea bass has delicious meat, no intermuscular thorns, and affordable prices. It is favored by consumers and has a huge consumer market. Breeding California perch in the Pearl River Delta region has unique geographical and climate advantages, and it also has obvious advantages in the industrial chain of seedlings, feed, and distribution. In recent years, with the maturity of the whole recipe and process of California perch, there has been an upsurge of California perch farming across the country. Since 2015, the total amount of California sea bass farming in the country has increased from the initial 300,000 tons to 500,000 tons in 2018, and it is expected tha...
