The authors Nguyen Duc Tien - Institute for Agricultural Engineering and Post Harvest Technology studied the production technology Oryzanol from rice bran, as raw material for the production of pharmaceuticals, cosmetics, food supplements anti-aging for women.
Taking you back hundreds of micronutrients from rice bran

With the amount of rice bran accounts for approximately 10% of the rice, the rice bran annual waste processing facility in the country's estimated 45 million tons of rice bran, rice bran is used primarily for food livestock, rice bran and often unpleasant rancid mold damage during storage, untapped potential inherent value of rice bran.

In fact apart from the valuable components such as protein nutrition. Lipids, glucocide, vitamins, ... rice bran contain compounds that are particularly important Oryzanol. Gamma Oryzanol as an important antioxidant in plants to combat ulcers, particularly stomach ulcers, lowering cholesterol, potentially increasing the blood circulation, reduce body fat and prevent the penetration of ultraviolet rays, preventing skin pigmentation, ...

Currently Gamma Oryzanol from rice bran is used as a raw material in the production of pharmaceuticals, cosmetics, food production adds support for women's anti-aging, reduce the symptoms of hot flashes and stress vagaries of menopausal women and postmenopausal period, as a dietary supplement to help develop muscles in the body, increasing strength, ...

Despite such effects, but at present Oryzanol preparations for production of cosmetics, pharmaceuticals and food products contain Gamma Oryzanol in our country are imported. In countries where no research basis Oryzanol products produced, raw materials are mostly imported from Japan, China and other countries.

Realizing the benefits of Gamma Oryzanol necessary development and production technology suitable Oryzanol, the authors Nguyen Duc Tien Institute of Agricultural Engineering and Post Harvest Technology undertook to implement the project "Research production technology research Oryzanol from rice bran ", from the results of the research, conducted group has built a production process technologies Oryzanol from rice bran.

Exploitation of byproducts left open

Process manufacturing technology Oryzanol from rice bran products is done through 12 steps, including: Selecting raw rice bran; Material handling; Extraction; Soap goods; Drying soaps; Extraction soap; Fee income extraction; Separation of wax; Filtrate, she; Gamma Oryzanol crystallization; Filter collection crystallization and drying Oryzanol Gamma Oryzanol crystalline powder.

From the technological process is built and based on the specifications of the technology process manufacturing Oryzanol from rice bran products are identified, the authors have carried out trial production Oryzanol from rice bran products rice at pilot scale.

Results from 120 kg of raw rice bran, produced 568 grams of Gamma Oryzanol preparations purity reaching 68.5%. Production Efficiency Gamma Oryzanol from rice bran reached 70.62% obtained 5,8kg soap embryos as raw material for soap processing.

Soap after Oryzanol extraction -0.8 atm vacuum drying at 70 ° C / 2 hours, embryos collected rice bran oil soap with moisture content of about 3.3, which is then brought to processed soap herbs. Results from 2kg soap billet production is 10 liters try herbal soap.

With the technological processes respectively, Oryzanol also be applied to produce functional foods and cosmetics as: Application for creating compositions Oryzanol Gamma Oryzanol food employees; Gamma Oryzanol application preparations produced for distribution formula made lotion; Gamma Oryzanol application preparations produced for distribution formula made hair cream; ...

Talking about the economic efficiency of production technology products Oryzanol from rice bran, author Nguyen Duc Tien said, the cost to produce 1kg of about 1.900.000đ Oryzanol, Gamma Oryzanol with quality equivalent to currently selling price of approximately 7.000.000d / kg. The results show that the technological processes for the production Oryzanol potential economic effects.

Such technology shows promise in the extraction of active ingredients from bio-products bran Gao now left open. In order to enhance the value of rice, creating domestic products Oryzanol is currently in great demand in the food processing industry, pharmaceutical and cosmetic products, contributing to developing mining industry active living from agricultural school ... need time to continue the development Oryzanol production in industrial scale production.
