Embodiment 1

[0020] A kind of preparation method of fish gelatin that the present invention proposes, comprises the following steps:

[0021] S1. Take out the swim bladder from fresh and healthy fish, first clean the blood stains on the outer surface of the swim bladder with clean water, soak in clean water for 20 minutes, then cut open at the joint of the swim bladder to release the gas in the swim bladder, and then rinse with clean water Knead and wash the inner surface of the swim bladder to obtain the cleaned swim bladder;

[0022] S2. Remove the dirty film on the surface of the swim bladder after internal and external cleaning to obtain the treated swim bladder. Wash the treated swim bladder with coarse salt for 5 minutes, then remove the coarse salt on the surface of the swim bladder, and then soak in chlorination at 40°C The mass concentration of sodium is 3% in brine for 10 minutes, and the quality of brine added is based on the fact that the brine interface is 2 cm above the level...

Embodiment 2

[0026] A kind of preparation method of fish gelatin that the present invention proposes, comprises the following steps:

[0027] S1. Take out the swim bladder from fresh and healthy fish, first clean the blood stains on the outer surface of the swim bladder with clean water, soak in clean water for 40 minutes, then cut open the swim bladder junction to release the gas in the swim bladder, and then rinse with clean water Knead and wash the inner surface of the swim bladder to obtain the cleaned swim bladder;

[0028] S2. Remove the dirty film on the surface of the swim bladder after internal and external cleaning to obtain the treated swim bladder. Wash the treated swim bladder with coarse salt for 3 minutes, then remove the coarse salt on the surface of the swim bladder, and then soak in chlorination at 50°C The mass concentration of sodium is 1% in brine for 20 minutes, and the quality of brine added is based on the fact that the brine interface is 5 cm above the level of the...

Abstract

The invention discloses a preparation method of fish gelatin sheets. The method comprises the following steps: S1, taking swimming bladders, cleaning the outer surface of the swimming bladders with clear water, soaking the swimming bladders in clear water, cutting open the swimming bladders at the junction, and kneading and cleaning the inner surface of the swimming bladders with clear water; S2,stripping visceral peritoneum, rubbing the swimming bladders with coarse salt, soaking the swimming bladders in salt water, removing fishy smell in fishy smell-removing juice, turning over the swimming bladders once every 1-3min, taking out the swimming bladders after removing fishy smell, washing the swimming bladders with clear water, and performing draining to obtain fishy smell-removed swimming bladders; and S3, placing the fishy smell-removed swimming bladders in a vacuum freeze dryer for vacuum freezing operation, placing the frozen swimming bladders in a pot, heating and melting the frozen swimming bladders to obtain a swimming bladder gelatin liquid, placing the swimming bladder gelatin liquid in a mould, obtaining a semi-finished fish gelatin product after the swimming bladder gelatin liquid is solidified, and then drying the semi-finished fish gelatin product in an oven so as to obtain the fish gelatin sheets and to finish the manufacturing of the fish gelatin sheets. The preparation method provided by the invention is simple to operate and low in cost, and the prepared fish gelatin sheets are good in taste and free from fishy smell and stink, and have wide application range.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a method for preparing fish gelatin sheets. Background technique [0002] Fish maw is the dry product of fish maw, which is rich in colloid, also known as fish maw and fish maw. Isinglass is as famous as bird's nest and shark's fin. It is one of the "Eight Treasures" and is known as "Marine Ginseng". The main components of isinglass are high-grade collagen, multivitamins, calcium, zinc, iron, selenium and other trace elements. Its protein content is as high as 84.2%, and its fat is only 0.2%. It is an ideal high-protein and low-fat food, a raw material for human body to supplement and synthesize protein, and is easy to absorb and utilize. Therefore, it is often used as a food additive to improve the nutritional value of food. Currently, isinglass sold in the market mainly includes isinglass powder and isinglass flakes, but the quality of isinglass flakes on the market ...
