Problems solved by technology

[0006] The methods in the prior art mainly obtain a fat composition suitable for cooking and frying by adding other types of antioxidants or synergists except biologically active substances, However, the types of effective antioxidants are very rare, and the existing technology still needs to develop an oil composition that does not rely on antioxidants and can effectively maintain the stability of biologically active substances

[0089] Preparation method of oil composition

[0090] The preparation method of the oil composition of the present invention comprises the step of mixing the base oil and the fractionated transesterified oil containing behenic acid.

[0091] In the preparation method of the oil composition of the present invention, based on the total amount of the oil composition, the added amount of the transesterified oil containing behenic acid is 0.1-10 wt%, preferably 0.2-9 wt%, more preferably 0.5 ~8wt%, more preferably 1~7wt%, more preferably 3~7wt%, especially preferably 3~5wt%. In a specific embodiment of the present invention, based on the total oil composition, the added amount of the fractionated transesterified oil containing behenic acid is 1wt%, 3wt%, 5wt%, 7wt%, 10wt%.

[0092] In the preparation method of the oil composition of the present invention, the oil composition is an oil composition that can be used for high temperature treatment. In some specific embodiments of the...

Embodiment

[0126]Among the following materials used in the present invention, behenic acid and ethyl behenate were purchased from Sichuan Tianyu Oleochemical Co., Ltd.; oleic acid, fully hydrogenated high erucic acid rapeseed oil, high oleic sunflower oil, rice oil, 24 degrees Palm olein, corn oil and soybean oil were all from Yihai Kerry Group; sodium methoxide was purchased from Sinopharm Group; immobilized fatty acids Lipozyme RM IM and NS40086 were purchased from Novozymes; tocopherol and squalene were from Fengyi Spring Valley Biotechnology (Jiangsu) Co., Ltd., β-carotene was purchased from Xi'an Haisifu Biotechnology Co., Ltd.; tea polyphenols were purchased from Henan Jinrun Food Additives Co., Ltd.; rosemary extract, tertiary butyl hydroquinone ( TBHQ), butylated hydroxyanisole (BHA), 2,6-di-tert-butyl-4-methylphenol (BHT) and ascorbyl palmitate (AP) were purchased from Tianjin Rongxin Blue Ocean Biotechnology Co., Ltd.

[0127] In the following invention examples, the compositio...

preparation example 1

[0130] Weigh 100 parts by weight of high oleic sunflower oil and 120 parts by weight of ethyl behenate in a reaction flask, stir at 75°C until completely dissolved, then add 10 parts by weight of immobilized lipase NS40086, and react for 6 hours. After the reaction is over, the immobilized enzyme is separated from the oil phase by suction filtration while it is hot, and the oil phase enters a short-range molecular distillation device to separate the light phase fatty acid ethyl ester (distillation conditions: distillation temperature 240°C, flow rate 2-3 drops / s , scraper speed 300rpm, vacuum degree -3 mbar), to collect the heavy phase oil. Add 4 times the volume of n-hexane to the heavy phase oil to dissolve at 60°C, and then crystallize at 30°C for 24 hours. When the crystallization time is reached, remove the crystalline solid by filtration, remove the n-hexane by rotary evaporation, and then carry out decolorization and deodorization steps to obtain the fractionated transe...

Abstract

The invention relates to a fat composition and a preparation method thereof. The fat composition contains fractionated and transesterified fat containing docosanoic acid. The fat composition providedby the invention can enable endogenous and exogenous biological active substances to maintain good stability under high-temperature conditions such as pan-frying, baking and cooking.

Description

technical field [0001] The invention relates to an oil composition and a preparation method thereof, as well as the use of fractionated transesterified oil containing behenic acid. Background technique [0002] In addition to providing energy and essential fatty acids, oils and fats also contain some active ingredients that have special physiological effects on the human body, such as phytosterols (esters), vitamin E, oryzanol, squalene, carotenoids, flavonoids and more Phenolic substances, etc., they play an important role in enhancing body function, improving immunity, delaying aging, lowering cholesterol, reducing the incidence of cardiovascular and cerebrovascular diseases and other physiological functions. In order to strengthen the physiological effects of the above-mentioned physiologically active substances in oils, people can often achieve this by increasing the content of the active substances in oils. For example, the loss of biologically active substances in the...
