Nutrition balanced mixed oil containing fish-oil or polyenoid fish-oil and its production method

Abstract

The invention provides nutritional blend oil containing fish oil or polyene fish oil. The blend oil adopts refined peanut oil, double-low rapeseed oil and other plant oil as raw material, fish oil and polyene fish oil is taken as mixing oil, and antioxidant agent consists of lipo-soluble tea polyphenol and vitamin E. Addition is calculated according to physical and nutritional requirement of various population and the content of various fatty acid in raw oil and mixing oil. Every 100g of product blend oil contains SFA 12-18g, MUFA 39-46g, omega-6 PUFA 31-38g and omega-3 PUFA 5-9g, wherein, total amount of omega-3 LCPUFA DHA+DPA+EPA is 0.1-5.0g, the ratio of DHA and (DPA+EPA) is 0.25-10:1, and the ratio of DHA and EPA is 4:1-25:1. The blend oil has the effect of promoting brain development, preventing myopia and early-aged dementia and reducing the occurrence of cardiovascular and cerebrovascular diseases, etc.

Description

technical field [0001] The invention relates to an edible blending oil containing additives, in particular to a nutritional blending oil and a preparation method thereof. Background technique [0002] For a long time, the health care function of vegetable oils in my country has not received enough attention, and various fatty acid components have not been rationally deployed. Regarding dietary intake of fatty acids, the World Health Organization and the Food and Agriculture Organization of the United Nations recommend that the daily intake of fatty acids in the human body should be based on the ratio of three fatty acids: saturated fatty acid (SFA): monounsaturated fatty acid (MUFA): polyunsaturated fatty acid ( PUFA) = 1:1:1 is suitable. At present, the supply of the first two fatty acids in edible oils in my country is sufficient and the supply of the latter is insufficient, but polyunsaturated fatty acids still play an important role in the human body, such as omega-6 se...

Problems solved by technology

Chinese patent CN1483336A discloses "balanced nutrition blending oil", which stipulates that the content ratio of monounsaturated fatty acid (MUFA) and polyunsaturated fatty acid (PUFA) is 1:1, and the content ratio of linoleic acid and α-linolenic acid The ratio is 4 to 6:1, but the ratio of saturated fatty acids is not considered, nor is ω-3 long-chain polyunsaturated fatty acid (ω-3 LCPUFA) directly added; The production method, although it considers the ratio of saturated fatty acid (SFA), monounsaturated fatty acid (MUFA) and polyunsaturated fatty acid (PUFA), also considers the omega-6 series fatty acid linoleic acid and the omega-3 series fatty acid α-linseed The proportion of acid content, but it has the following defects: 1. No direct addition of ω-3 long-chain polyunsaturated fatty acid (ω-3 LCPUFA), the long-chain ω-3 polyunsaturated fatty acid (ω-3 LCPUFA) required by the human body LCPUFA) is only obtained from the conversion of omega-3 linolenic acid in the human body, which cannot meet the needs of the human body

2. Oils with different ingredients and ratios are not provided according to the needs of people of different ages and health conditions

[0005] Chinese patent application CN1398532A discloses "a preparation method of functional olive oil concentrate", Chinese patent application CN1398533A discloses "a functional olive high-grade cooking oil and its preparation method", Chinese patent application CN1191677A "a pure natural Although deep-sea fish oil is added to the formula of "functional edible oil", the above-mentioned patent application has the following problems: 1. Whether the total amount and composition of fatty acids meet the requirements of human nutrition balance is not considered, and the daily intake of fatty acids by the human body is not divided into three types of fatty acids. The ratio of saturated fatty acid (SFA): monounsaturated fatty acid (MUFA): polyunsaturated fatty acid (PUFA) = 1:1:1 is the premise of adding deep-sea fish oil; 2. The main active ingredients in deep-sea fish oil are not mentioned or explained The physiological and health effects of DHA and EPA, not to mention the lack of analysis of the content of DHA and EPA in deep sea fish oil, will inevitably lead to unclear supplement purposes and inaccurate supplement dosage

In practical application, due to different manufacturers and specifications, the content and ratio of omega-3 long-chain polyunsaturated fatty acids DHA and EPA in fish oil are also different. Adding deep-sea fish oil without accurately calculating the content of DHA and EPA will inevitably cause The amount of supplementation is inaccurate, and there is a phenomenon of low or high levels; low levels cannot meet the physiological needs of the human body, and excessive intake will cause peroxidation reactions due to the unsaturated double bonds in the structure, resulting in lipid peroxides. This kind of free radical is one of the risk factors for promoting aging and cancer, and produces various chronic harms to the body. For example, if this lipid peroxide appears in the skin, it will form lipofuscin and appear senile plaques; if it appears in the cell, It will weaken the cell function; excessive intake of unsaturated fatty acids in obese patients can easily cause cholelithiasis; studies have shown that the rise of lipid peroxide in the blood is more harmful to the formation of atherosclerosis than the rise of cholesterol

3. The weight ratio of added DHA to EPA is unscientific and cannot meet the physiological needs of different food objects

Therefore, the content ratio of DHA and EPA is unscientific, which may also affect the health of certain groups of people.

4. Although deep-sea fish oil containing ω-3 long-chain polyunsaturated fatty acids (ω-3 LCPUFA) has been added to the edible oils of the above three formulas, no heating stability test has been carried out, and how many components can be retained after cooking and heating is also unknown
