The invention discloses a separation method of oleic acid and linoleic acid in tea seed oil, which includes the steps of: saponifying and acidifying the tea seed oil to obtain mixed fatty acid; pre-removing saturated fatty acid through a freezing crystallization method; and finally purifying the oleic acid and the linoleic acid through a urea inclusion method. In the method, the saturated fatty acid is separated in a certain degree by means of difference of melting point of the saturated fatty acid and unsaturated fatty acid for the first time, and then saturated and monounsaturated fatty acids are separated from polyunsaturated fatty acids through the urea inclusion to further prepare the oleic acid and the linoleic acid at high purity. Compared with the prior art, synchronous separation of the oleic acid and the linoleic acid in the tea seed oil is achieved. The method not only enriches the oleic acid in the tea seed oil but also separates the linoleic acid, and meanwhile increases the purities of the oleic acid and the linoleic acid. The method solves the problem that only is the oleic acid or the linoleic acid can be separated individually in the prior art and increases the additional value of products and raw material utilization rate.

The present invention improves biodiesel production in several ways. Unique combinations of unit operations and flow configurations are disclosed in mobile processing units that are feedstock-flexible and can be dynamically deployed in a distributed way. In some embodiments, a process includes introducing a waste oil and an alcohol into a reactor with an esterification-transesterification enzymatic catalyst. Free fatty acids are reacted with alcohol to produce fatty acid alkyl esters, and glycerides are reacted with alcohol to produce fatty acid alkyl esters and glycerin. A membrane separator removes glycerin, water, and alcohol. Unreacted free fatty acids are then separated and recycled, to generate a product stream with fatty acid alkyl esters. A genset may be provided for combusting glycerin to produce electrical power and thermal heat as co-products. This biodiesel process may be energy self-sufficient, require no external utilities, and avoid direct discharge of wastewater.

The invention relates to the field of health food, specifically to rice bran oil with lung-moistening and stomach-harmonizing health-care effects The rice bran oil is prepared from the following raw materials by weight: 1350 to 1500 parts of rice bran, 38 to 40 parts of hickory nut kernel, 55 to 58 parts of pine nut, 20 to 25 parts of camellia seed, 15 to 18 parts of mint, 14 to 16 parts of Indian trumpetflower seed, 12 to 16 parts of coriander seed, 13 to 16 parts of dried orange peel, 12 to 15 parts of perilla leaf and 10 to 12 parts of barley malt According to the invention, the rice oil is prepared by using carbon dioxide subcritical extraction technology, production process is environment friendly and highly efficient, extraction temperature is low, and a plurality of beneficial biologically-active components in the raw materials are not destroyed; a compound of rice bran and oil plants with a great edible value like the hickory nut kernel, the pine nut and the camellia seed is used as a carrier, active substances in Chinese herbal medicines are extracted into oil, so the rice bran oil provided by the invention has comprehensive nutrients and rich and unique fragrance, greatly whets the appetite of people smelling the fragrance of the rice bran oil, can moisten the lung, calm panting, soothe the liver, harmonize the stomach, invigorate the spleen, promote digestion, etc, and is a good health preserving and health-care product

The present invention is concerned with an edible plant oils from which saturated fatty acids were removed and manufacturing process thereof. In order to remove saturated fatty acids from the edible plant oils; 1) Saturated and unsaturated fatty acids bound on same triglyceride molecules of edible plant oils were segregated each other as alkylesters of fatty acids by conventional transesterification reaction in which edible plant oils were treated with large excess of absolute C 1 ˜C 8 alkanol under the presence of catalytic amount of alkali- or alkali-earth metal-C 1 ˜C 8 alkoxide. 2) The alkyl-esters of mixed fatty acids were treated with C 1 ˜C 8 alkanol solution of urea to remove the alkylester of saturated fatty acids by conventional fractional crystallization as urea complexes of saturated fatty acid-alkylesters. 3) Finally the resulting alkylesters of unsaturated fatty acids, obtained by removal of saturated fatty acids by urea complexation procedure, was converted to reconstructed triglyceride oil to give edible plant oils completely devoid of saturated fatty acids. This new manufacturing process could be successfully applied to following 22 kinds of edible plant; 1) corn oil, 2) soybean oil, 3) rapeseed oil, 4) grape seed oil, 5) flaxseed oil, 6) sesame oil, 7) olive oil, 8) perilla oil 9) wall nut oil, 10) pine-nut oil, 11) peanuts oil, 12) sunflower oil, 13) safflower oil, 14) cotton seed oil, 15) palm oil, 16) hot pepper oil, 17) rice bran oil, 18) pumpkin oil, 19) green tea seed oil, 20) almond oil, 21) evening primrose oil and 22) hazelnut oil.

Disclosed is a denatured spirulina of being removed the unpleasant smell of spirulina, of maintaining its nutrients undestroyed, of being changed the unpleasant deep blue color from light blue to rose pink, and of showing higher suspensible nature to cold water, characterized in that spirulina is suspended in distilled or purified water to destroy its cell membranes by osmolytic treatment, so the chromoprotein phycocyanin leaks out of the cell membranes; chromoprotein in the spirulina is partially denatured by heating the resulting mixture; condensing, condensing under reduced pressure or finally freeze-dried the resulting mixture.

Flaxseed or its oil rich in α-linolenic acid attracts public attention due to its improving activity for plasma lipid profiles including plasma cholesterol and neutral lipids. However, fatty acids therein will reduce such beneficial effects of a-linolenic acid. In addition, it contains also neurotoxic cyanogen glycosides and immuno-suppressive cyclic nonapeptides. Therefore, in order for flaxseeds oil to be used as edible food for reducing the plasma level of cholesterol and hyperlimidemia, it is preferable to remove these toxic components and saturated fatty acids from flaxseed or its oil before using as edible food. The present invention concerned with novel reconstructed triglyceride from flaxseed oil composed of unsaturated fatty acids in which saturated fatty acids and toxic components were completely removed and manufacturing process for preparing the reconstructed triglyceride by procedures comprising: flaxseed oil is saponified with alkali solution and at the same time cyclic nonapeptides are completely destroyed contained in the flaxseed oil; after saponification, the reaction mixture is acidified and heated sufficiently with excess amount of mineral acid to destroy cyanogen glycosides ; mixture of fatty acids was obtained by routine process and dissolved in alcoholic solvent, and treated with alcoholic solution of urea to separate out saturated fatty acids as crystalline urea complex; from the filtrate unsaturated fatty acid fraction was obtained by routine process as acidification, hexane extraction and concentration and treated with oxalyl chloride to produce acyl chloride of unsaturated fatty acid; and the acyl chloride of unsaturated fatty acid is reacted with glycerine to produce reconstructed triglyceride composed of unsaturated fatty acids.
