Description

A kind of production method of nutrition and health care roxburghii powder

technical field

The invention relates to a production method of nutritional and health-care Rosa roxburghii powder, specifically referring to transforming Rosa roxburghii into a nutritional and health-care Rosa roxburghii rich in vitamin C and various active ingredients with powerful anti-oxidation, free radical removal and anti-aging functions Powder production method.

Background technique

Prickly pear (Rosa roxburghii Tratt) belongs to the Rosaceae plant. It is a perennial shrub. The fruit body is covered with soft thorns. The fruit shape is like a pear. When the fruit is fresh, it is light green in color, sweet and sour, slightly astringent, and has a special and strong aroma. Rosa roxburghii originates in Southwest China, with Guizhou being the best. It is a new generation of nutritional and health-care fruit treasures with high nutritional value. Rosa roxburghii fruit contains a large amount of vitamin C (V _C ), superoxide dismutase (SOD), Every 100 grams of fresh fruit contains an average of 1800-2500 mg of vitamin C, 54000 U of SOD, 3000 mg of vitamin P, 4 grams of fructose and trace elements, among which the average content of V _C is 10 times that of kiwi fruit, 50 times that of sweet orange, and apple 455 times that of prickly pear, rich in the reputation of "Queen of Fruit V _C ", plus all the fruits of SOD and V _P Xiongguan, known as "Fruit of the Three Kings". (Cities) Except for the three counties of Congjiang, Rongjiang and Weining, there are more distributions in other counties and cities.

In recent years, it has been proved by scientific and medical research that Rosa roxburghii can inhibit the synthesis of strong carcinogen NN-nitrosourea or NN-nitrosoproline in organisms, and can effectively prevent the potential carcinogenic danger of such substances. Superoxide dismutase, also known as SOD, is an effective substance that can effectively remove superoxide free radicals in the human body, thereby improving the body's immunity and delaying aging. The United States calls it "fading factor" and is widely used in medicine and health care Food and cosmetic products. At present, domestic SOD is mainly extracted from animals and plants. However, due to extraction from animal blood, it is difficult to eliminate various viruses and external pollution. European countries have issued an order in 1999 to prohibit the use of animal blood to extract SOD for humans. The output of SOD extracted from the medium is small, and it is difficult to realize industrial production. Experiments have proved that Rosa roxburghii has very good functions of detoxification, detoxification, and heavy metal lead removal. It has a strong effect on detoxification and removal of various chemical drug toxins accumulated in the human body for a long time, and the effect of preventing colon cancer is particularly prominent. In addition, it has been clinically proven that Rosa roxburghii has good anti-disease and fatigue effects, and can enhance the body's resistance to hypoxia and fatigue. Rosa roxburghii contains a large amount of functional oxygen substances such as V _C and SOD, which can significantly enhance the body's immunity. In recent years, Rosa roxburghii has been widely used in health food and medicine, and its reputation has spread far and wide.

Most of the thorn pear products currently on the market are juice liquid products, which have short shelf life, poor circulation, and single dosage forms, which are difficult to promote in large quantities, which restricts the planting and production of thorn pears. Rosa roxburghii is mainly wild, with low utilization value. The price per ton of fruit is less than 2,000 yuan/ton. The enthusiasm of farmers is not high, and the income is low, which has not brought good benefits to local farmers.

Vitamin C is a water-derived vitamin, which is the most unstable of all vitamins. It is easily destroyed, oxidized and decomposed during storage, processing and cooking. Rosa roxburghii fruit is easy to decompose and lose VC _and SOD during processing, and the final product has low _VC and SOD content and is not easy to process into powder, especially Rosa roxburghii powder with high content of _VC , which has not been found in the market yet.

Deep processing of prickly pear produces high-content V _C powder, which can increase the value several times to dozens of times. For the prosperity of the mountainous economy, the pace of poverty alleviation of mountain farmers, the construction of a new socialist countryside, the deep processing of prickly pear characteristic resources, and the improvement of its utilization value , are all significant.

Contents of the invention

The purpose of the present invention is to provide a kind of Rosa roxburghii processed into the nutritious and health-care Rosa roxburghii powder rich in V _C and multiple active ingredients aiming at the shortcomings of the single product and the shortage of high-content V _C product dosage forms that exist in the deep processing of thorn pears at present. production method.

The purpose of the present invention is achieved through the following technical solutions:
