Description

TECHNICAL FIELD The present invention relates to an aerated oily and fat food that is difficult to remove air bubbles even after time has elapsed after production and that has a soft texture.

In recent years, spread foods such as peanut cream, which are spread and applied to bread and confectionery, have been favored products that have a soft texture by including bubbles.

As such food, for example, JP-A-11-164671 (Patent Document 1) discloses a peanut butter processed food that is whipped and has a soft texture.

However, in order to have a soft texture, a large amount of air bubbles must be contained. In this case, the air bubbles are easily removed during storage, and the soft texture is impaired, resulting in a sticky texture. There was a problem. In addition, in aerated food containing starchy aqueous solution such as flour paste, for example, JP 2004-254611 (Patent Document 2) improves the foaming property by blending a high HLB emulsifier. Although technology has been disclosed, it has not been so much studied to keep a soft texture by making it difficult for air bubbles to escape from oil and fat foods.

Japanese Patent Laid-Open No. 11-164671 JP 2004-254611 A

Accordingly, an object of the present invention is to provide an aerated oily and fat food that is difficult to remove air bubbles even after time has elapsed after production and that has a soft texture.

As a result of intensive studies on various conditions such as raw materials used to achieve the above object, the present inventors have blended a specific emulsifier and eggshell calcium, and a specific amount of eggshell calcium with respect to the specific emulsifier. When blended, it was surprisingly found that an air-containing oily and fat food that hardly causes bubbles to escape and retains a soft texture was obtained, and finally the present invention was completed.

That is, the present invention
(1) The hardness of the product is 3.0 × 10 ^{4 to} 1.5 × 10 ⁵ N / m ² , and 10 to 40% by volume of inert gas is contained with respect to the non-aerated product volume. In the aerated oil and fat food, a decaglycerin behenic acid ester of HLB 5 or less and eggshell calcium are blended, and an aerated fat and oil food in which 0.1 to 10 parts of eggshell calcium is blended with respect to 1 part of the decaglycerin behenic acid ester,
It is.

According to the present invention, it is difficult to remove bubbles even after the time has elapsed after production, and it is possible to provide an aerated fat and oil food having a bubble stability that retains a soft texture. Can contribute.

Hereinafter, the aerated fat and oil food of the present invention will be described in detail. In the present invention, “part” means “part by mass”.

The aerated fat and oil food of the present invention is a food containing an inert gas by blowing an inert gas into a food mainly made of fat or fat such as shortening, butter, margarine, lard, or peanut butter. is there. The use of the aerated fat and oil food is not particularly limited, and examples thereof include bread spreads used by spreading on bread and the like, toppings for various dishes, and fillings. In addition, the moisture content of the aerated oil-fat food is preferably 3% by mass or less, more preferably 2% by mass or less, from the viewpoint that the deterioration of flavor during storage and changes in physical properties such as oil separation can be suppressed. The water content of the composition is a value measured according to the reduced pressure heating drying method described in the third column of Appendix 2 of the Nutrition Labeling Standard (April 24, 2003, Ministry of Health, Labor and Welfare Notification No. 176).

The air content of the inert gas in the aerated fat and oil food of the present invention is 10 to 40% by volume, preferably 20 to 40% by volume, based on the unaerated product volume. Examples of the inert gas include tasteless and odorless gases such as nitrogen, argon gas, and carbon dioxide gas. When the air content is within the above range, a soft texture can be obtained.

Further, aerated fat food of the present invention, hardness of the product ^{3.0 × 10 4 ~1.5 × 10 5} N / m 2, more preferably 5.0 × ¹⁰ 4 ~1.0 × ^{10 5} N / m ² , thereby making it possible to obtain an aerated oily and fat food product in which bubbles are difficult to escape and a soft texture is maintained. Here, the above-mentioned hardness is a value measured at a product temperature of 20 ° C. using a creep meter (RE-3305, manufactured by Yamaden Co., Ltd.). Specifically, the product is put into a stainless steel petri dish having a diameter of 40 mm and a depth of 15 mm until it is fully cut, placed on a measurement table, a 20 mm diameter cylindrical plunger is used, and the product is 10 mm at a table moving speed of 10 mm / sec. It is the value which measured the hardness at the time of moving.

The aerated fat and oil food of the present invention contains HLB5 or less decaglycerin behenate and eggshell calcium, and eggshell calcium is 0.1 to 10 parts, preferably 0.5 to 5 parts per 1 part of the decaglycerin behenate. 8 parts is blended. Thereby, even if time passes after manufacture, air bubbles are hard to escape and the aeration oily fat food by which the soft texture was kept is obtained. On the other hand, unless both the decaglycerin behenate and eggshell calcium are blended, it is difficult to keep bubbles in the fat and oil food for a long time. Moreover, even if these are blended, if the blending ratio of eggshell calcium to decaglycerin behenate is less than the above ratio, it is difficult to keep air bubbles in the fat and oil food for a long period of time, whereas if more than the above ratio, the flavor unique to eggshell Strongly undesirable.

The decaglycerin behenic acid ester used in the present invention is obtained by esterifying behenic acid to polyglycerin having an average degree of polymerization of 10. In the present invention, a decaglycerin behenic acid ester having an HLB (hydrophilic / lipophilic balance) of 5 or less is used, and an HLB of 4 or less is preferable because air bubbles can be maintained for a long time. In addition, the minimum of HLB is 1 or more by industrial productivity.

In addition, the eggshell calcium used in the present invention is a product obtained by dividing a general eggshell of birds, taking out egg yolk and egg white, washing and drying, and processing into a powder or granule, and is usually used in foods. If it is, The main component of eggshell is calcium carbonate, which contains about 2% by mass of protein. Although the mechanism of keeping bubbles in fat and oil foods is not clear, it is speculated that this protein may have some influence on the retention of bubbles.

The blending amount of decaglycerin behenate having an HLB of 5 or less of the present invention is preferably 0.01 to 1% by mass, more preferably 0.05 to 1% by mass, based on the product. If the blending amount is less than the above amount, the bubbles cannot be kept in the oily food for a long time. On the other hand, if the blending amount is larger than the above amount, the bubbles can be kept in the fats and oils food, but the whole product becomes hard, which is not preferable. is there.

The aerated fat and oil food of the present invention may contain an emulsifier other than the HLB5 or lower decaglycerin behenate within the range that does not impair the effects of the present invention for the purpose of various quality improvements. In addition, if a large amount of hydrophilic emulsifier is blended, it may be difficult to obtain the effect of the present invention that retains air bubbles. Therefore, the average HLB of all emulsifiers blended in the product is preferably 1 to 10, 8 is more preferable.

In addition, the fat and oil raw material blended in the fat and oil food of the present invention is not particularly limited as long as it is a fat and oil raw material blended in a general fat and oil food. For example, rapeseed oil, corn oil, olive oil, safflower oil, cottonseed oil, soybean oil , Rice oil, corn oil, vegetable oil such as refined salad oil, animal oil such as butter, lard, beef tallow, egg yolk oil, or oil seed paste such as peanut paste, almond paste, sesame paste Etc., and one or more of these can be blended. In the present invention, among these oil / fat raw materials, the vegetable oil / fat having a rising melting point of 30 ° C. or higher is particularly preferably 10 to 95% by mass, and more preferably 20 to 70% by mass, with respect to the product. In particular, it is preferable because it has an appropriate shape retaining property and an effect of retaining bubbles is easily obtained. Specific examples of vegetable oils and fats having an ascending melting point of 30 ° C. or more include, for example, palm oil and fat, fractionated oils and oils collected from high melting points, and rapeseed oil, corn oil, safflower oil, cottonseed oil and soybean oil. And hardened oils and fats obtained by hydrogenating vegetable oils such as sunflower oil. In addition, the said rising melting point in this invention is the value measured by the measuring method of the rising melting | fusing point of edible vegetable oil described in Japanese agricultural and forestry standard 2467 pages.

In addition to the above-mentioned emulsifier, eggshell calcium and oil and fat raw materials, the aerated oil and fat food of the present invention includes, for example, isomerized liquid sugar, fructose, glucose, maltose, starch syrup, honey, lactose, syrup, oligosaccharide, and sugar alcohol. , Sweeteners such as dextrin, cyclodextrin, sucralose, stevia, aspartame or sugar, salt, dried egg yolk, dried egg white, powdered milk, cocoa, chocolate and other seasoning ingredients, vegetables such as parsley, spinach, peppers, basil, oregano, Herbs such as rosemary, mineral iron, heme iron, calcium, potassium, magnesium, zinc, copper, selenium, manganese, cobalt, iodine and other minerals, ascorbic acid or salts thereof, antioxidants such as vitamin E, difficulty Digestible dextrin, crystalline cellulose, dietary fiber such as apple fiber, fruit Ba, fragrances such as vanilla flavor, can be appropriately selected blended colorant such as within a range that does not impair the effects of Honmyo.
