Description

A kind of Korean pine nut blended oil and its preparation process

technical field

The invention relates to a blended oil and a preparation process, in particular to a Korean pine nut blended oil and a preparation process.

Background technique

Blended oil is a fashionable edible oil variety formed to meet the needs of modern people for a healthy diet. Fat is one of the three main components of human food. It not only has the characteristics of supplying heat, forming body cells, dissolving nutrients, and regulating physiological functions, but also is the main source of essential fatty acids that cannot be synthesized by the human body and must be ingested to maintain health. Sources (such as linoleic acid, linolenic acid, etc.). With the advancement of science and technology and the improvement of people's living standards, dietary nutrition has gradually attracted people's attention. At present, in addition to advocating the consumption of more vegetable oil, people are also required to change the long-term habit of only eating one kind of oil, and mix more than two kinds of oil to learn from each other. Reconcile and eat, so as to obtain a kind of oil with more balanced fatty acid composition and higher nutritional value.

Since the 1990s, scholars at home and abroad have done a lot of research on the physiological metabolism of various fatty acids in the human body. Western developed countries, the Food and Agriculture Organization of the United Nations and the World Health Organization have all proposed the proportion of various fatty acids in the human body. corresponding standard. Although vegetables, eggs, milk and other foods in people's daily diet also contain a small amount of fatty acids, the proportion is still very low compared to the total amount of various fatty acids ingested by the human body. The consumption of animal food by the vast majority of residents in my country is mainly pork, beef and mutton, accounting for about 30% of the total body fat intake. Animal fat contains more saturated fatty acids, and the daily intake of residents varies greatly, so it is difficult to control and balance the intake. Therefore, to develop and develop a blended oil with a reasonable ratio of fatty acids suitable for human metabolism, the key is to solve the problems of monounsaturated fatty acids (MUFAs) in unsaturated fatty acids (UFAs) in the deployment of vegetable oils that account for about 70% of the total body fat intake. ) to polyunsaturated fatty acids (PUFA) in a ratio of 1:1 and PUFA in a ratio of omega-6 fatty acids to omega-3 fatty acids of 4-6:1. It is of great significance to study new blended oils that meet the fatty acid ratio standards proposed by the Chinese Nutrition Society and are suitable for human metabolism.

The fatty acids in the natural diet are divided into SFA, MUFA and PUFA, and because of their different chemical structures and physical properties, they also have different effects on health. Different fatty acids have different nutritional functions. Excessive or insufficient intake of a certain type of fatty acid will lead to metabolic disorders in the human body and cause diseases. A reasonable proportion of fatty acids in blended oil is crucial to human growth, development and disease prevention, especially for reducing plasma cholesterol and blood sugar levels, preventing hyperlipidemia, atherosclerosis, cardiovascular diseases and tumors, and enhancing immunity, etc. is of great significance.

Contents of the invention

The purpose of the present invention is to provide a kind of Korean pine nut blended oil and its preparation process in order to solve the problem that the current single oil has a single component and cannot meet people's nutritional needs.

The Korean pine nut blend oil provided by the invention comprises 10-20 parts of Korean pine nut oil, 10-30 parts of corn oil, 50-80 parts of peanut oil, 0.04-0.05 parts of vitamin E, tert-butyl Hydroquinone (TBHQ) 0.01-0.02 parts.

The preparation technology of the Korean pine nut deployment oil provided by the invention, its concrete technology is as follows:

The first step, preparation of main raw materials: take 10-20 parts of Korean pine nut oil, 10-30 parts of corn oil, and 50-80 parts of peanut oil by weight, and the quality of raw materials will meet the requirements of GB2716-2005 standard;

The second step, deployment: deploy the Korean pine nut oil, corn oil and peanut oil in the first step, the deployment standard by weight in the deployment oil is: saturated fatty acid (SFA) content is 10-20 parts, monounsaturated The fatty acid (MUFA) content is 25-45 parts, the polyunsaturated fatty acid (PUFA) content is 40-55 parts, and the weight ratio of monounsaturated fatty acid (MUFA) and polyunsaturated fatty acid (PUFA) is 1:(1-1.5 ), the weight ratio of ω-6 polyunsaturated fatty acid to ω-3 polyunsaturated fatty acid is (4.5-5.2): 1;

In the third step, add 0.04-0.05 parts of vitamin E and 0.01-0.02 parts of tertiary butyl hydroquinone (TBHQ) to the blended oil prepared in the second step by weight, at a temperature of 40-45°C , set the speed of the blending tank at 100-150rpm and stir for 20-30min, after stirring evenly and fully dissolving, pack to obtain the finished product.

Beneficial effects of the present invention:

The present invention is based on the recommended intake and ratio of fats and fatty acids for Chinese residents by the Chinese Nutrition Society, and in consideration of the balance of other nutritional components in plants, chooses Korean pine seed oil as the main ingredient, and adds other vegetable oils for blending. Control saturated fatty acid (SFA) content to 9-15 parts, monounsaturated fatty acid (MUFA) content to 25-45 parts, polyunsaturated fatty acid (PUFA) content to 40-50 parts, polyunsaturated fatty acid (PUFA) and monounsaturated fatty acid (PUFA) The ratio of unsaturated fatty acid (MUFA) is 1:(1-1.5), and the weight ratio of omega-6 polyunsaturated fatty acid to omega-3 polyunsaturated fatty acid is (4.7-5.2):1. The oil composed of such fatty acids can not only adjust the various fatty acids in the dietary fat to achieve an ideal ratio, which is beneficial to the digestion and absorption of the human body. Long-term consumption can prevent nutritional deficiencies, and at the same time, it can effectively inhibit cardiovascular diseases such as cholesterol and high blood pressure. .
