The R&D team of Seawit upgraded its patented technology of moderate oil refining jointly developed with Bohai Industry and Jiangnan University, and successfully applied it to the refining of microbial oils and applied for invention patents.
On the basis of the original vegetable oil moderate refining technology, Seawit adopts the updated anhydrous coagulation low-temperature degumming technology, silicon gel adsorption low-temperature decolorization technology, steam jet pump film flash evaporation deodorization technology and other moderate refining technology, which not only reduces The production cost also fully retains the antioxidant active ingredients and stabilization system of the microbial oil itself, which can produce refined oils with zero trans fatty acids. The application of these new technologies can increase the refining yield of Haizhiyuan DHA/ARA oil by more than 2%, make the content of trans fatty acids in DHA/ARA essential oil less than 0.3%, and fundamentally solve the problem of product flavor and quality stability. , Greatly expand the application range of microbial oil DHA and ARA in the food field.
The research and development team of Seawit Company analyzed the effects of traditional processes on the quality and safety of DHA/ARA in response to many problems such as nutrient loss caused by excessive processing of DHA/ARA oil, high trans fatty acid content, DHA/ARA quality and flavor instability, etc. By changing the production process and technical parameters, according to the influence of each production process on the content of trace components in DHA/ARA grease, equipment transformation, process improvement and technical parameter adjustment are carried out step by step, and finally a moderate processing is achieved and the amount of trans fatty acids is reduced. Produced, fully retaining the natural active nutrients such as vitamin E and carotenoids in the oil. The refining process of DHA/ARA is carried out completely in a closed environment. By using core technologies such as moderate refining technology, natural nutrient recovery and capture technology, low temperature and short-term treatment technology, full nitrogen filling and fresh-keeping and anti-oxidation technology, avoid damage to DHA/ARA grease Its own anti-oxidation system solves the problem that many companies' DHA/ARA oils in the market have good initial quality, but after a while, the product quality and flavor deteriorate sharply. Coupled with the preservation of nitrogen filling to avoid air infiltration into the oil, the oil can maintain the stability of quality and flavor without adding any antioxidants.
Moderate refining technology has formed a complete set of production technology regulations, management regulations and product standard systems, which have been appraised by the Chinese Institute of Cereals and Oils and conform to the international advanced level.
