preparation example Construction

[0026] A method for preparing plateau rapeseed oil suitable for children, comprising the steps of:

[0027] 1) Taking plateau rapeseed oil as the base oil, selecting plateau rapeseed oil of 40-80% by weight, and adding 10-40% by weight of linseed oil to it for mixing to ensure the linoleic acid and The ratio of α-linolenic acid is less than 3:1;

[0028] 2) Pump the mixed oil prepared in step 1) into the enzyme reaction tank, and add lipase, phospholipase and water in sequence, wherein the lipase is Lipozyme RM liquid enzyme, and the phospholipase is phospholipase A1 and phospholipase A2. Press down and heat to 40-80 degrees, react for 2-8 hours, and perform centrifugal dehydration and enzyme after the reaction;

[0029] 3) The material after step 2) centrifugal dehydration is then distilled by molecular distillation equipment, and low-component substances such as glycerin, fatty acid and monoglyceride are removed by three-stage molecular distillation, and the remaining is th...

specific Embodiment 1

[0043]Specific Example 1: Rapeseeds in the western Sichuan plateau area are used as raw materials, cleaned and removed by vibrating sieves, dried at 100 degrees for 30 minutes, and passed through a peeling machine after cooling to ensure that the skin rate in the rapeseed kernels does not exceed 5%. , the skin contains no more than 4% kernels, and the peeled rapeseed is sent to a screw press for oil extraction. By controlling the amount of feed, the temperature of the press is controlled at 85-88 degrees, and the rapeseed oil is placed in a settling tank on the plateau. 25 minutes, the pressure is 0.3MPa nitrogen, and then under the condition of nitrogen seal, stand still for 20 days.

[0044] According to the fatty acid detection results of highland rapeseed oil and linseed oil, the weight ratio of highland rapeseed oil and linseed is obtained by measuring the ratio of linoleic acid and α-linolenic acid at 3:1: highland rapeseed oil 64%, linseed oil 36%; and deploy highland r...

Abstract

The invention discloses a preparation method of plateau rapeseed oil suitable for children to eat. The preparation method comprises the following steps of taking the plateau rapeseed oil as a raw material, and adding 10-40% by weight of linseed oil; adding mixed oil into composite lipase and water, carrying out an enzymolysis reaction, and then carrying out three-stage molecular distillation for purification and separation; and then adding 0.5-5% by weight of lysophospholipid-type DHA and 0.01-1% of rosemary as a natural anti-oxidant, and stirring the components uniformly. The rapeseed oil prepared with the method is added with the linseed oil to adjust the fat ratio for enabling fatty acid of the rapeseed oil to be more balanced; grease is partially hydrolyzed through the lipase, so thatpart of triglyceride is converted into diglycerides, in-vivo accumulation of the grease is not caused when a child eats the rapeseed oil excessively, and the obesity problem of the children due to thegrease problem is avoided; and meanwhile, the added lysophospholipid-type DHA is easier to absorb and utilize by the human body than ethyl ester and triglyceride type DHA.

Description

technical field [0001] The invention belongs to the technical field of edible oil processing, and in particular relates to a preparation method of plateau rapeseed oil which is suitable for eating by children and has health care functions such as balancing fatty acids and strengthening brain development for children. Background technique [0002] Rapeseed oil, referred to as "vegetable oil", is mainly obtained from the seeds of Brassica oleracea and Chinese cabbage-type rapeseed. The unsaturated fatty acid content of rapeseed oil is as high as 85%, and it is rich in oleic acid, linoleic acid, linolenic acid and phospholipids. The human body digests and absorbs it as high as 99%. Rapeseed oil is rich in vitamin E and polyphenols , squalene, sterols and other bioactive ingredients. Unsaturated fatty acids can regulate blood lipids, clear blood clots, regulate immunity, maintain the retina, nourish the brain, improve arthritis symptoms and relieve pain. [0003] Trans fatty a...
