BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a low-calorie fat and oil which prevents the phenomenon of anal leakage.

2. Description of the Related Art Obesity is considered to be an unfavorable health phenomenon, and the cause of obesity is that more calories are ingested than consumed. For this reason, it is believed that adjusting the calorie intake of foods to an appropriate value is effective in preventing obesity.

On the other hand, fat greatly contributes to the flavor of foods, but since it has a calorie density more than twice that of carbohydrates and proteins, reducing its intake is effective in optimizing calorie intake. . Many studies have been conducted to solve the two problems of reducing the calories ingested from fat without sacrificing the flavor of this food.

Specifically, in US Pat. No. 3,600,186, Mattson et al. took advantage of the fact that polyesters of sugars such as sucrose and fatty acids such as oleic acid are not digested and absorbed, and used them as low-calorie fats and oils for this purpose. It states what to do. However, liquid sucrose polyester has had the undesirable side effect of anal leakage.

[0005] A method for preventing this side effect is Janda
Cek, filed as US Pat. No. 4,005,195. This is a method of preventing side effects by adding free saturated fatty acids or polyhydric alcohol esters containing saturated fatty acids to liquid sucrose polyester as an anal leakage preventive agent.

[0006] Furthermore, many patents have been filed regarding methods for preventing anal leakage by using saturated fatty acids as fatty acids in sucrose polyester (Japanese Patent Application Laid-Open No. 1983-1999).
222671, 64-2533, 64-6288,
64-34244, 64-34245, 64-3
4918). Furthermore, it is also known to be used in fibers as an anal leakage prevention agent (Japanese Patent Application Laid-Open No. 2-227051).

[0007] Anal leakage has also been observed in low-calorie fats and oils made of polyorganosiloxane fluid, and an application has been filed to use silica particles, triglycerides containing saturated fatty acids, fibers, etc. to prevent this (Japanese Patent Laid-Open No. 2-2195).

Furthermore, it has been reported that anal leakage was observed when jojoba oil and polycarboxylic acid esters, which are other low-calorie oils, were administered to rats (Hamm et al.
,D. J. (1984) J. Food Sci. 49
:419).

[0009]

[Problems to be Solved by the Invention] However, among conventional anal leakage prevention agents, free saturated fatty acids and triglycerides containing saturated fatty acids are digested and absorbed, so they contain calories, and saturated fatty acids increase serum cholesterol. It is undesirable because it has an adverse effect on heart disease.

An object of the present invention is to solve the problems of conventional low-calorie fats and oils by means that do not have the above-mentioned drawbacks, and thereby provide a low-calorie fat and oil that does not cause anal leakage.

That is, the present invention is a low-calorie fat and oil containing a wax having a melting point of 40° C. or higher as an anal leakage prevention agent.

[0012] The wax used in the present invention must have a melting point of 40°C or higher, and if it does not meet this requirement, it will not substantially be effective in preventing anal leakage. Examples of the wax used in the present invention include sunflower wax, rapeseed wax, sesame wax, rice wax, sugarcane wax, carnauba wax, candelilla wax, montan wax, spermaceti wax, shellac wax, and beeswax.

Among these, sunflower wax is separated in the dewaxing step during sunflower oil refining, and the separated crude wax can be used as it is, but it is preferable to use purified wax with increased wax content by fractionation with hexane or the like. Use wax. The wax content in crude wax is about 20%, but in refined wax it is 90% or more.

[0014] Also, rapeseed wax, sesame wax, rice bran wax, etc. are almost the same as sunflower wax.

[0015] Since these waxes are not decomposed by lipase, they do not provide calories even when ingested, and when added to low-calorie fats and oils, they do not inhibit the original functions of low-calorie fats and oils.

The appropriate amount of these waxes to be added is 2 to 50% by weight based on the low calorie fat or oil.

[0017] The low-calorie fats and oils referred to in the present invention include various known substances that cause anal leakage when left alone, such as sucrose polyester, polyorganosiloxane fluid,
Examples include polycarboxylic acid esters and jojoba oil.

[0018]

[Example] Example 1 (1) Purification of sunflower wax 2 kg of crude wax (18% wax, 81% sunflower oil, 1% other) obtained in the dewaxing process of sunflower oil was
Dissolve in 50 liters of hexane while heating at 50°C. Next, when this hexane solution was cooled to 10°C, sunflower wax crystallized, and was separated by filtration.
g of purified wax was obtained. When the wax content in purified wax was analyzed by gas chromatography, it was found to be 9.
It was 1%.

(2) Lipase Decomposition Experiment A sample oil was prepared by dissolving 0.5 g of purified wax in 500 g of soybean oil while heating at 70°C. 1 g of sample oil at pH 8 (1M
) Enzymatic decomposition was performed at 40°C in an aqueous solution containing 20 ml of Tris buffer, 5 ml of 0.1% sodium cholate, and 2 ml of 2M-CaCl2 while stirring while changing the amount of lipase (pancreatin manufactured by Wako Pure Chemical Industries, Ltd.). .

The reaction was stopped by adding 5 ml of 6N-HC1, and the mixture was extracted with ether and subjected to gas chromatography to measure the residual rate of soybean oil. In addition, this ether extract was subjected to a silica gel column to remove soybean oil decomposition products, further concentrated by thin layer chromatography, and then subjected to gas chromatography to measure the residual rate of wax. As a result, it was confirmed that wax was hardly decomposed even under conditions where soybean oil (triglyceride) is decomposed (Table 1).

[0021]

[Table 1]

(3) Experiment on Digestion and Absorption by Animals 9 parts of soybean oil and 1 part of the purified wax described above were added to 90 parts of a compound feed for animals (fat-free, hereinafter the same) and administered to rats for one week. Three days after administration, feces were collected, lipids were extracted, and the amount of wax excreted was determined. As a result, 95% of the administered wax
% was excreted in feces, confirming that the wax was not digested and absorbed (Table 2).

[0023]

[Table 2]

Example 2 85 kg of jojoba oil was heated to 60° C. or higher, and purified sunflower wax 15 obtained in Example 1 was used as an anal leakage prevention agent.
kg was added little by little while stirring, and the mixture was completely dissolved by heating. The sunflower wax is then turned into fine crystals by cooling while stirring using an onlator.
A low-calorie shortening with good taste and excellent shelf life was produced.

[0025] The effects of this low-calorie shortening were confirmed in animal experiments. A control diet containing 85 parts of compound feed for laboratory animals, 10 parts of lard, and 5 parts of soybean oil, and an experimental diet in which part or all of the lard was replaced with low-calorie shortening were administered to rats for 3 weeks to determine lipid excretion. The amount was measured to determine the lipid absorption rate, and the amount of weight gain was determined. As a result, the lipid absorption rate of the rats fed the experimental diet decreased, and their weight gain decreased, but no anal leakage was observed, and the survival rate of the rats was 100%, and all of them were actively active. . On the other hand, anal leakage occurred in the comparative example (when only jojoba oil was given), and it was confirmed that sunflower wax is effective as an anal leakage prevention agent (Table 3).

[0026]

[Table 3]

Example 3 After mixing 200 kg of jojoba oil and 140 kg of olive oil, the mixture was heated to 60°C or higher, and 160 kg of the crude sunflower wax of Example 1 was added little by little while stirring as an anal leakage prevention agent, and the mixture was heated completely. It was dissolved to produce a low calorie fat. 380kg of this low calorie oil and fat with 5 emulsifiers
oil phase mixed with 3 kg of flavor, 20 g of coloring, 7 kg of salt and 5 kg of skim milk powder in 100 liters of water.
and the aqueous phase in which it was dissolved were placed in a tank and uniformly emulsified at 60°C. Low calorie margarine was then produced by rapidly cooling the mixture while stirring using an onlator.

Example 4 280 kg of jojoba oil and 120 kg of rapeseed oil were heated at 60°C.
After heating to the above temperature, 100 kg of commercially available rice wax as an anal leakage preventive agent was added little by little while stirring and completely dissolved by heating to produce a low-calorie fat or oil. When low-calorie margarine was produced in the same manner as in Example 3 using this low-calorie fat and oil, a product with a slightly darker color than the low-calorie margarine of Example 3 was obtained. This one did not cause anal leakage.

Example 5 Carnauba wax produced in Canada was deoxidized and deodorized to obtain a purified wax that complied with the standards for food-grade hydrogenated oil. 300 kg of jojoba oil and 170 kg of corn oil were heated to 60°C or higher, and 30 kg of purified wax was used as an anal leakage prevention agent.
Add g little by little while stirring and completely dissolve by heating.
Produced low calorie fats and oils. Using this low-calorie fat and oil, low-calorie margarine was produced in the same manner as in Example 3. This one did not cause anal leakage.

Example 6 400 kg of oleyl alcohol triester of propanetricarboxylic acid was heated to 60° C. or higher, and purified Himawari wax 100 obtained in Example 1 was used as an anal leakage prevention agent.
kg was added little by little while stirring and completely dissolved by heating to produce a low calorie fat. When low-calorie margarine was produced in the same manner as in Example 3 using this low-calorie fat and oil, a product with a slightly lighter color than the low-calorie margarine of Example 3 was obtained.

The effects of this low calorie margarine were confirmed through animal experiments. Rats were given an experimental diet containing 85 parts of compound feed for laboratory animals and 15 parts of low-calorie margarine for 3 weeks, and a control diet in which margarine was similarly prepared using only oleyl alcohol triester of propanetricarboxylic acid. The presence or absence of anal leakage was determined, and the amount of weight gain was measured (Table 4).

Example 7 Margarine with the formulation shown in Table 5 containing sucrose octaoleate as the main component, hydrogenated soybean oil, and purified sunflower wax obtained in Example as an anal leakage preventive agent was turned on. Manufactured using a rotor. As comparative examples, we also produced samples in which sucrose octaoleate was replaced with soybean oil and in which no anti-anal leakage agent was added.

[0034]

[Table 5]

[0035] 80 parts of a compounded feed for experimental animals and 20 parts of margarine of Examples or Comparative Examples were mixed and administered to obese rats for 5 weeks. As a result, Comparative Example A was found to be obese.
In Comparative Example B, anal leakage was observed and activity was inactive. In contrast, in the products of the present invention, there was no anal leakage, obesity was not observed, and the animals were active.

[0036]

[Effects of the Invention] According to the present invention, the problem of low-calorie fats and oils that conventionally caused anal leakage is effectively solved.
An improved low calorie fat without anal leakage is obtained.
