Description
Technical Field
The invention relates to the technical field of cream processing, in particular to a preparation device and a preparation method of selenium-rich cream.
Background
Cream (Cream) is a milk product prepared by subjecting milk to centrifugal separation to obtain dilute Cream, ripening, stirring, and refining. Cream is one of favorite foods, is rich in nutrition by taking milk fat as a main component, but the cream with high fat content is prohibitive to many people. At present, the demand of low-fat cream in European and American market and international market is continuously rising, and the traditional cream is more and more not suitable for the requirements of consumers in the current society on health, green and health care. The formula is improved and the production process is innovated on the basis of the traditional margarine, so that the method conforms to the consumption psychology of consumers in the current society, develops healthy low-fat cream by taking low fat and high nutrition as the points of penetration, and has wide market prospect.
Selenium is a trace element necessary for human body, and has biological properties of resisting cancer, resisting oxidation (aging), improving human immunity, antagonizing heavy metals, etc. At present, five thousand scientific papers report that selenium has a protective effect on the liver. The Chinese Nutrition society recommends a daily intake of 50-250 micrograms. However, the daily selenium intake of adults in China is only about 40 mu g, so that the situation of selenium malnutrition generally exists in China. In China, 72% of county (city) soil is low in selenium or is lack of selenium, and naturally, cancers, cardiovascular diseases and eye diseases in low-selenium areas are higher than those in selenium normal areas. The data published by the WHO indicates that over 40 countries around the world belong to areas with low or no selenium. The food and drink are effective ways for supplementing selenium element for human body, but the selenium content in the food and various drinks depends on the selenium-containing level of the raw materials for processing the food and various drinks. A lack of selenium content in the soil will eventually lead to a relative lack of selenium in the food chain. There are two ways to ensure that food contains sufficient selenium: firstly, selenium nutrition is strengthened in the planting and production processes of processing raw materials; secondly, the selenium is added in the form of selenium additive in the production process.
The cream processed in the market at present is not added with selenium, so that the selenium-rich cream product is prepared, and the selenium-rich cream product has a wide market prospect.
