Abstract

PURPOSE:To obtain an oil and fat food free from the back-flow of ill-smelling belch from the stomach to the mouth after taking a highly unsaturated fatty acid, by compounding a triglyceride containing a highly unsaturated fatty acid with a vegetable sterol. CONSTITUTION:A triglyceride containing highly unsaturated fatty acids such as eicosapentaenoic acid, docosahexaenoic acid, gamma-linoleic acid, etc. is compounded with a vegetable sterol such as beta-sitosterol, stigmasterol, etc. at a weight ratio of 95:5-5:95, preferably 70:30-30:70.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an oil and fat food containing highly unsaturated fatty acid-containing triglycerides and plant sterols, and the oil and fat food can be encapsulated, tableted, granulated, etc. It is consumed as nutritional food.

[Conventional technology]

Since Guilherg announced that eicosaben citric acid has antithrombotic and cholesterol-lowering effects, polyunsaturated fatty acids, especially eicosaben citric acid,
Because docosahexaenoic acid is effective in preventing and treating adult diseases, it is widely used as a nutritional food, as shown in Japanese Patent Application Laid-Open No. 5.7-86254 and Japanese Patent Application Laid-Open No. 58-849. Consumers are now ingesting it. In addition, T-lylunic acid, as a prostaglandin precursor, is effective in the prevention and treatment of adult diseases, so it has come to be ingested by general consumers as a nutritional food.

Further, Japanese Patent Application Laid-Open No. 59-82070 describes a method of mixing lecithin with eicosapentaenoic acid and docosahexaenoic acid as a method for preventing unpleasant taste when ingesting highly unsaturated fatty acids.

[Problem that the invention seeks to solve]

However, the above-mentioned highly unsaturated fatty acids have a unique unpleasant odor, and even if they are ingested in capsule form, the odor will flow back into the mouth as burps after ingestion, and even though they are good for health, they will continue to be ingested. It wasn't easy.

In addition, the above-mentioned Japanese Patent Application Laid-Open No. 59-82070 does not mention the unpleasant odor caused by burping after ingestion, and lecithin itself has a unique odor unless it is of extremely high purity. Although it may be good for those who like lecithin, it is not appropriate for those who dislike it.

An object of the present invention is to provide an oil and fat food that prevents odor from flowing back into the oral cavity as genop from behind the intake of highly unsaturated fatty acids.

[Means for solving problems]

The fat and oil food of the present invention is characterized by containing highly unsaturated fatty acid-containing triglycerides and plant sterols.

The highly unsaturated fatty acid-containing triglycerides used in the present invention are oils and fats containing eicosapentaenoic acid or docosahexaenoic acid obtained from fish oil, whale oil, krill oil, etc., or oils and fats containing T-linolenic acid obtained from evening primrose seeds, etc. etc., and this highly unsaturated fatty acid-containing triglyceride may contain saturated fatty acids, monounsaturated fatty acids, and diunsaturated fatty acids in addition to highly unsaturated fatty acids. The highly unsaturated fatty acids may exist in the form of triglycerides, diglycerides, monoglycerides, alcohol esters with ethanol, etc., or as free acids.

Examples of highly unsaturated fatty acids include eicosapentaenoic acid, docosahexaenoic acid, and T-linolenic acid, and one or more of these may be contained.

The content of highly unsaturated fatty acids is preferably about 5 to 70% by weight of the fat and oil components.

The plant sterols used in the present invention include β-ntosterol, stigmasterol, campesterol, and ergosterol obtained from plant seeds that are usually used as raw materials for oils and fats, such as soybean, cottonseed, rapeseed, rice bran, and corn. etc., and one type of these may be used, or two or more types may be used in combination.

The above-mentioned plant sterols may be highly purified ones, or may contain components derived from raw plant seeds, such as phospholipids, carbohydrates, tocopherols, glycerides, and catyloids within the scope of the present invention. do not have.

The blending ratio of the above-mentioned highly unsaturated fatty acid-containing triglyceride and the above-mentioned plant sterol is preferably about 95=5 to 5:95, particularly about 70,230 to 30,000 by weight.

Triglycerides containing highly unsaturated fatty acids and plant sterols are both lipids, and can be easily mixed in any ratio by heating above their melting point. It is possible to obtain the effect of

In addition to the above two ingredients, the fat and oil food of the present invention also contains vitamin E,
It may further contain synthetic antioxidants such as vitamin C1, carbohydrates such as starch, proteins such as skim milk powder, fragrances, spices, and the like.

The oil and fat food of the present invention, which is a mixture of highly unsaturated fatty acid-containing triglycerides and plant sterols, can be taken in the form of soft capsules, tablets, granules, etc., and can also be taken as margarine, shortening, kutsky, biscuits, chocolate, bread. It can be ingested by adding it to foods such as

〔Example〕

Examples of the present invention are shown below, but the present invention is not limited thereto. In addition, "parts" in the examples are "parts by weight"
shows.

Example 1 10 parts of fish oil containing 12% by weight of eicosapentaenoic acid, 8 parts of soybean-derived phytosterol, and natural vitamin E
0.1 part was heated and dissolved while stirring in a nitrogen stream,
After homogenization, this was filled into 300 mg soft gelatin capsules to obtain encapsulated oil and fat foods.

Example 2 After homogenization in the same manner as in Example 1 using 1 part of fat and oil containing 25% by weight of eicosapentaenoic acid and 13% by weight of docosahexaenoic acid and 8 parts of a plant sterol mixture derived from soybeans and cottonseeds as raw materials, was filled into 400 mg soft gelatin capsules to obtain encapsulated oil and fat foods.

Example 3 10 parts of evening primrose oil containing 8% by weight of T-linolenic acid, 0.7 parts of rapeseed-derived plant sterol, and natural vitamin E
An encapsulated fat/oil food was obtained in the same manner as in Example 1 using 0.05 part as a raw material.

When the encapsulated oil and fat foods obtained in Examples 1 to 3 were sampled at 3 tablets at a time, 3 times a day for 7 days, they all reduced burping accompanied by the unpleasant odor characteristic of highly unsaturated fatty acids.
Or, it did not occur and continued intake was possible.

Example 4 5 kg of the homogenized product obtained in the same manner as in Example 2 was mixed with 971 kg of β-cyclodext and granulated using a pelletizer to obtain a granulated fat and oil food.

When this granulated oil and fat food was taken at 3 g at a time, three times a day for 7 days, no burping accompanied by the unpleasant odor characteristic of highly unsaturated fatty acids occurred.

Example 5 150 g of the granulated oil and fat food obtained in Example 4 was added to 500 g of vegetable margarine mainly composed of soybean oil, and then homogenized in a small kneader to produce margarine containing eicosapentaenoic acid and docosahexaenoic acid. did.

When 10 g of this margarine was spread on bread and tasted once a day for 7 days, no burping accompanied by the unpleasant odor characteristic of highly unsaturated fatty acids occurred.

〔Effect of the invention〕

The effect of the present invention is that triglycerides containing polyunsaturated fatty acids, which are said to be effective in the prevention and treatment of adult diseases, but which are difficult to ingest continuously because they tend to cause unpleasant symptoms after ingestion. , it is possible to suppress the burping and stop taking it continuously.
