Embodiment 1

[0017] 1. Preparation of swim bladder slurry. Take 0.5kg of small, low-value dry eel maw without pests and mildew, and perform routine cleaning and crushing; soak in drinking water 10 times the weight of the swim bladder for 60 minutes; add 20kg of drinking water according to the solid-to-liquid ratio of 1:50, and stir , Homogenizing to obtain swim bladder slurry;

[0018] 2. Enzymatic hydrolysis of swim bladder. Add 0.5% flavor protease (3.0×10 4 u / g, Novo Company), under the conditions of pH 6.8 and temperature 55°C, enzymolysis was performed for 3 hours; the temperature was raised to 90°C, and the enzyme was inactivated for 9 minutes; centrifuged at 4000 rpm for 20 minutes to obtain the supernatant;

[0019] 3. Debittering and deodorization of enzymatic hydrolyzate. Add 1.0% white sugar, 0.2% citric acid, and 1.5% yeast to the supernatant, and incubate at pH 6.0 and 34°C for 45 minutes; then, add 1.0% β-cyclodextrin, Incubate for 55 minutes; centrifuge at 8000rpm for 6 ...

Embodiment 2

[0023] 1. Preparation of swim bladder slurry. Take 0.3kg of sharp fish maw without pests and mildew, and carry out routine cleaning and crushing; soak in drinking water 12 times the weight of fish maw for 80 minutes; add 12.9kg of drinking water according to the solid-liquid ratio of 1:55, stir and homogenize fish maw slurry;

[0024] 2. Enzymatic hydrolysis of swim bladder. Add 0.75% flavor protease (3.0×10 4 u / g, Novo Company), at a pH value of 6.8 and a temperature of 55°C, enzymolysis was performed for 4 hours; the temperature was raised to 90°C, and the enzyme was inactivated for 9 minutes; centrifuged at a speed of 4500rpm for 15 minutes to obtain a supernatant;

Abstract

The invention discloses a preparing method of a swim bladder protein beverage, belonging to the technical field of aquatic product processing. The swim bladder protein beverage uses dry swim bladder as raw material and is produced after the preparation, the enzymatic hydrolysis, the debiting and deodourizing, the blending, the can filling and the sterilizing of swim bladder slurry. Enzyme is adopted for the controllable degradation of the swim bladders. The reaction conditions are mild. Few nutritional components are lost. A compound method is adopted for debiting and deodourizing enzyme solution. And the special masking function of natural products is also adopted. After the flavoring, the swim bladder protein beverage with perfect taste and flavor and both nutritional and healthy values is obtained. The preparing method of the swim bladder protein beverage improves the processing level and added value of the swim bladders, eliminates poor flavors of swim bladder protein degradation products of fishy smell, bit, and the like and can be applied to the industrialized production. The beverage has the advantages that the product nutritional value is high, the digestion and absorption are easy and the drinking is convenient.

Description

technical field [0001] A method for preparing a swim bladder protein drink belongs to the technical field of aquatic product processing and relates to a preparation method for a swim bladder protein drink. Background technique [0002] Swim bladder, commonly known as fish maw, is an ideal high-protein, low-fat food. In our country, eating swim bladder has a long history. In the Northern Wei Dynasty Jia Sixie's "Qi Min Yao Shu" there is a record of processing and eating totoaba swim bladder. In the Tang Dynasty, fish maw became a tribute. "New Book of Tang Geography" records: Wu Jun (now Suzhou City) pays "swim bladder (swim bladder) seven catties" every year. By the Qing Dynasty, fish maw was listed as a tonic. Fish maw is not only a famous dish at rice dumplings, but also has considerable nourishing effect and medicinal value, such as nourishing yin and nourishing blood, stopping bleeding and nourishing blood, nourishing kidney and nourishing essence. In terms of medici...
