Safe nutritious original-bottle freshly-stewed instant dried swimming bladder and preparation technology thereof

Abstract

The present invention relates to a safe nutritious original-bottle freshly-stewed instant dried swimming bladder and a preparation technology thereof. The technology processes comprise ice water soaking, washing and stewing in original bottles under high temperature and high pressure. The preparation technology avoids problems of partial nutrient loss and easy deterioration of dried swimming bladders in a process of high-temperature rapid soaking swelling or long-time soaking swelling for 18 hours or more, and also shortens process time. The technology conducts original-bottle fresh stewing under high temperature and high pressure, specifically, conducts soaking swelling, stewing and sterilizing in a same bottle, can better lock nutrients, and is safer. The dried swimming bladder product is directly subjected to the soaking swelling, stewing and sterilizing in the original bottle, so that the preparation technology avoids that transferring of the dried swimming bladders to other containers causes loss of nutrients and avoids mixing with bacteria or impurities; and the prepared dried swimming bladder product retains relatively high nutritional value, also has a suitable mouthfeel and is more in line with consumer edible preferences.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a safe and nutritious preparation process of freshly stewed and ready-to-eat fish maws in original bottles. Background technique [0002] Isinglass is a dry product of fish maw, rich in gelatin, so it is called isinglass, also known as fish maw and fish maw. Isinglass is as famous as bird's nest and shark's fin, and is one of the "eight treasures". Its main components are collagen, multivitamins, calcium, zinc, iron, selenium and other trace elements. Its protein content is as high as 84.0%, and its fat is 0.2%, which is an ideal high-protein and low-fat food. It is the raw material for the human body to supplement protein, and it is also the food that the human body can easily absorb and utilize. [0003] At present, the production process of isinglass is made by washing, decontaminating and drying the swim bladder; the cooking method of isinglass is usuall...

AI Technical Summary

Problems solved by technology

The existing isinglass is quickly soaked in hot water or soaked in cold water for a long time of more than 18 hours, and then stewed. The long-term soaking process of more than one hour will cause some nutrient loss and the problem that the gelatin is easy to deteriorate; sub-packaging after stewing is likely to cause secondary pollution, which is unsafe; secondary high-temperature sterilization is easy to destroy or lose nutrients

Therefore, there are technical deficiencies and defects in the foaming, steaming and packaging processes of the prior art, which cause nutrients such as vitamins and collagen in food to easily lose and are unsafe. With rapid economic development and improved living standards, people Have a deeper understanding of food culture. From the perspective of nutrition and food safety, this method is not scientific and needs to be improved

Therefore, the instant isinglass made by the prior art production process can not meet people's needs, and there is not yet a safe and nutritious stewing method
