Problems solved by technology

[0004] There are many methods about the feed additive technology for increasing fish meat quality. The prior art, such as the Chinese invention patent application public number CN102845647 B, discloses a Chinese herbal medicine feed additive for improving carp meat quality and a preparation method thereof. The inventive method combines Eucommia, Dandelion The Chinese herbal medicine feed additive is obtained by mixing the concentrated solution of , Angelica dahurica, Chinese yam, and chrysanthemum with the volatile oil collected by distillation of chrysanthemum. It can only improve the disease resistance and antibacterial properties of carp, improve its immunity, but cannot improve its digestion and absorption, and cannot change the quality of its fat and protein. Therefore, the degree of improving carp meat quality is relatively limited

Embodiment 1

[0018] The preparation method of the shallow sea fish feed additive that increases meat tenderness comprises the following steps:

[0019] 1) Homogenize fresh bighead carp viscera into a container, add an equal amount of distilled water, stir in a water bath and heat up to 33°C, adjust the pH to 8, continue stirring and heat up to 55°C, keep warm for 35 minutes, add fish viscera weighing 8% The potassium chloride was stirred and dissolved, salted out for 30 minutes, and then centrifuged while it was hot to separate crude fish oil; the fish viscera oil was extracted by potassium method to remove impurities and prepare for further modification;

[0020] 2) Weigh 150 parts of crude fish oil and 0.05 parts of vitamin E, mix them evenly in a closed container, place the reaction container in an ultrasonic instrument, heat it to 68°C and keep it, continue to supply oxygen for 10 minutes, and then add desaturase 0.5 parts, 0.1 parts of reduced coenzyme II, 0.06-parts of functional pol...

Embodiment 2

[0024] The preparation method of the shallow sea fish feed additive that increases meat tenderness comprises the following steps:

[0025] 1) Extract fish viscera oil: Take fresh bighead carp viscera and homogenate it into a container, add an equal amount of distilled water, stir in a water bath and raise the temperature to 36°C, adjust the pH to 9, continue to stir and heat up to 57°C, keep warm for 45 minutes, add Potassium chloride with a weight of 10% of fish viscera was stirred and dissolved, salted out for 40 minutes, and then centrifuged while it was hot to separate crude fish oil; this method has a high yield of fish oil and is easy to operate. Waste water and waste residue can be made into green and efficient fertilizers for complete comprehensive utilization. It can be used as a raw material for nucleic acid extraction to further increase the value, achieving the purpose of comprehensive utilization of waste;

[0026] 2) Fish oil modification: Weigh 180 parts of crud...

Embodiment 3

[0030] The preparation method of the shallow sea fish feed additive for increasing the tenderness of the meat comprises: extracting fish visceral oil, modifying the fish oil, preparing traditional Chinese medicine preparations, and compounding additives, specifically including the following steps:

[0031] Extract fish viscera oil: take fresh bighead carp viscera, remove the digestive residues in the viscera, wash and drain, homogenize in a homogenizer, weigh the fish viscera and homogenate it into a container, add an equal amount of distilled water, and stir Put in a water bath and raise the temperature to 35°C, adjust the pH to 8.5, continue to stir and raise the temperature to 56°C, keep it warm for 40 minutes, add potassium chloride with a weight of 8% of the fish viscera, stir to dissolve, salt out for 35 minutes, then centrifuge while it is hot, and separate the crude fish oil; Potassium method extracts fish visceral oil to remove impurities and prepare for further modifi...

Abstract

The invention discloses a preparation method of a feed additive of shallow sea fish for increasing the meat tenderness. The preparation method comprises the following steps: extracting fish visceral oil, modifying the fish oil, preparing traditional Chinese medicine preparations and compounding an additive. The method has the beneficial effects that the hydrogen of a carbon-carbon double bond at the middle position of saturated fatty acid can be abstracted by oxygen for generating water through an enzymatic reaction, so that a long-chain saturated fatty acid loses hydrogen and is converted into a corresponding unsaturated fatty acid, and thus the fish visceral oil is rich in polyunsaturated fatty acids such as DHA, EPA and the like, and is especially rich in homeopathic unsaturated fatty acid. The fat structure in the shallow sea fish body can be effectively improved, and the elasticity and tenderness of the fish meat are enhanced. The additive is rich in nutrients such as traditionalChinese medicine components, phospholipid, vitamin, nucleotide, complex enzyme and the like, and is suitable for being used as a feed additive of the shallow sea fish in cooperation with the phagostimulant and antioxidant components. When the additive is taken with the feed, the stress resistance, the immunity, the disease resistance and the anti-bacterial capability of the fishes can be enhanced,digestion and absorption of nutrient substances are promoted, and growth and development are accelerated.

Description

technical field [0001] The invention belongs to the field of fish feed additives, and in particular relates to a preparation method of shallow sea fish feed additives for increasing meat tenderness. technical background [0002] Shallow sea fish generally refers to fish that live within a depth of 200 meters close to the sea surface. There are many kinds of shallow sea fish, such as pomfret, yellow croaker, hairtail, grouper and so on. In recent years, due to the sharp decline in the number of wild shallow sea fishes, many former shallow sea fishes have been successfully farmed. Therefore, many common shallow sea fish currently on the market are actually derived from farming. The representatives are yellow croaker, turbot, grouper, golden pomfret and so on. Every time the depth in the sea exceeds 10 meters, there will be a kilogram of pressure per square centimeter. In conversion, at a water depth of 1,000 meters, the pressure per square centimeter will be as high as 100 ...
