Oyster Extract introduction

Oyster extract is the abbreviation of a mixture separated and extracted by a special method from the whole oyster. It is rich in glycogen, taurine, 18 kinds of amino acids, B vitamins, polysaccharides, low molecular active peptides, Fe, Zn, Se and other minerals and trace elements. At present, oyster alcohol extract and oyster water extract are commonly used. It has a variety of biological activities, such as improving immunity, anti-tumor, liver protection, etc. It has been widely used in functional food, nutritional food, medicine and other fields.

The oyster shell can be used to prepare oyster shell lime with dyeing function, and the mixture of oyster shell and clay can be used to prepare cement, which is widely used in construction, decoration and other fields. The oyster shell powder is not only high in calcium, but also rich in various trace elements. In addition, oyster shells can also be used to prepare various feed additives, fertilizer additives, cement additives, paint additives and soil conditioners.

Oyster Extract application

1. Development and utilization of health functional products and medicine

In recent years, the United States, Europe, Japan and other countries have adopted modern biotechnology, high-tech food processing, new chemical and other technical means to research and develop functional active ingredients in oysters. There are many kinds of health care therapeutic products, food additives, condiments and other products that have been developed. Japan has the most fully developed oyster health products. More than 50 kinds of functional food and therapeutic products are produced from oyster soft extract. The dosage forms include powder, granule, paste, capsule, liquid, etc. In the United States, oyster functional food and therapeutic products and other nutritional auxiliary foods have become a major industry, while in Europe, functional food fortified with taurine, glutathione and other substances in oysters has also emerged.

In the field of health functional products and medicine in China, oysters have also been used to prepare many health products and medicines. The oyster extract obtained by modern enzymolysis, fermentation and other technical means contains a large number of functional oligopeptides, polypeptides, amino acids and other nutrients, which has been widely used in functional food, nutritional food, medicine and other fields. Using oyster shell as raw material, a calcium additive with good solubility and dispersibility was prepared by ultrafine grinding technology. In addition, the active (ionized) calcium processed from oyster shells has anti-cancer effects, can prevent and treat diabetes, rickets, skin allergic diseases, and can treat a variety of other diseases. This is the basis of product development with oyster shell as the main raw material.

2. Development and utilization in the food industry

In the field of food industry, there are oyster primary processing products and deep processing products. The primary processing mainly adopts the methods of fresh processing, dry processing, salting, and pot storage, such as steamed oysters, fresh fried oysters, raw and burned oysters, oyster soup, oyster dried products, frozen products, oyster soy sauce, and oyster sauce refining. Oyster sauce is the most popular product processed with oysters as raw materials, which is deeply loved by many consumers at home and abroad. The convenience of food is the trend of food development today. With the acceleration of people's life rhythm, convenient food is more and more popular with the public. As a kind of highly nutritious aquatic product, oyster has the disadvantage that it will die soon after being naturally placed after water leaving, and it is easy to be contaminated by microorganisms and corrupt. Therefore, oysters can be made into various oyster cans to meet the needs of consumers. Oyster intensive processing is mainly the product development by using modern enzyme technology, fermentation technology, ultra-fine grinding technology, etc. Two kinds of condiments rich in amino acids, oyster sauce and soup, can also be prepared by enzymatic hydrolysis of oyster meat. After oyster enzymolysis, the utilization rate of protein is improved, which is more conducive to human absorption. At the same time, the product tastes more delicious and has higher nutritional value.

3. Development and utilization of oysters in other fields

The oyster shell can be used to prepare oyster shell lime with dyeing function, and the mixture of oyster shell and clay can be used to prepare cement, which is widely used in construction, decoration and other fields. The oyster shell powder is not only high in calcium, but also rich in various trace elements. In addition, oyster shells can also be used to prepare various feed additives, fertilizer additives, cement additives, paint additives and soil conditioners.
