Problems solved by technology

However, when it replaces fish meal in a high proportion, it will have a certain impact on the physiological health of aquatic animals, such as reduced feed digestibility and reduced appetite.
[0004] Cinnamaldehyde is the main active ingredient of traditional Chinese medicine cinnamon, which has anti-inflammatory and antibacterial effects. It is reported that it also has a certain food-attracting and growth-promoting effect on aquatic animals. However, due to its insoluble and easily oxidized characteristics, it has not Too much attention by feed workers in the aquaculture industry

Embodiment 1

[0026] The preparation method of cinnamaldehyde derivative shown in formula I:

[0027]

[0028] Cinnamyl alcohol (1.34 g, 10 mmol) was added to 100 mL of DMF, the compound of formula II (1.69 g, 12 mmol) was added dropwise, 10 mmol of triethylamine was added, and the reaction was heated to 40 °C. After the reaction is complete, the DMF is distilled off under reduced pressure, the mixture obtained by the reaction is poured into water, and then extracted with dry dichloromethane. The aqueous layer is extracted with dichloromethane, and the organic phases are combined, dried in vacuo to obtain a solid, and rinsed with ethanol to obtain the formula I compound 2.57 g (pale yellow liquid, yield 98.0%, purity 98.3%).

[0029] 1 H-NMR (CDCl 3 -d 6 ,500MHz)δ:2.11-2.13(t,1H),4.42-4.44(d,2H),4.82-4.84(d,2H),6.21(s,1H),6.54(s,1H),7.15-7.28( m,6H).

Embodiment 2

[0031] Preparation of the yeast extract:

[0032] Each 10L of high-quality brewer's yeast is filtered, impurity-removed, and debittered, and centrifuged in a high-speed centrifuge at a speed of 4000 r / min for 30 minutes. The reaction was incubated for 24 hours under the condition of degrees Celsius, the temperature was raised to 90 degrees Celsius and the reaction was incubated for 2.5 hours, and the soluble components were separated and concentrated, and spray-dried to obtain the Saccharomyces cerevisiae extract.

Embodiment 3

[0034] Preparation of the fish meal substitute containing yeast extract:

[0035] 8 g of yeast extract is mixed with 2 g of cinnamaldehyde or cinnamaldehyde derivative (as shown in formula I) and stirred evenly to obtain a fish meal substitute containing yeast extract.

Abstract

The invention discloses a fish meal substitute containing a yeast extract. The fish meal substitute containing the yeast extract has better protein content and absorption conversion rate than fish meal, has a food promoting effect, and can significantly reduce the irritability of aquatic animals. The invention further discloses a premix composition for the aquatic animals, wherein the premix composition is suitable for being applied to aquaculture of the aquatic animals, especially fishes and shrimps.

Description

technical field [0001] The invention belongs to the field of aquatic animal feed, in particular to a fish meal substitute containing yeast extract and an aquatic animal premix composition. Background technique [0002] my country is a big consumer of aquatic products. In recent years, my country's aquaculture model is gradually changing from the traditional natural stocking type to the large-scale and intensive farming method, which is followed by a large demand for aquatic animal feed. Aquatic animal feeds have very high requirements for high-quality protein sources. Protein sources are divided into animal protein and vegetable protein. Fish meal has always been one of the most popular in aquaculture due to its high protein content, comprehensive amino acid types, and easy digestion and absorption by aquatic animals. important source of protein. However, with the rapid development of the world aquaculture industry, the price of fish meal in the world continues to rise, whi...
