Description

  The present invention relates to an edible cream and a method for producing the same.

  Natural cream produced by separating milk fat from raw milk is very excellent in terms of flavor, but in the state before whipping, the product temperature during storage is likely to increase and solidify, At the time of whipping, roughness and fluttering easily occur, and there were difficulties in handling. In addition, fresh cream has a problem that it is expensive in price. In addition, pure milk cream has less physical properties than whipped, but is less expensive than compound cream and pure vegetative cream, which will be described later, and is more expensive in price. There wasn't. Furthermore, in recent years, it is also known that there are nutritional problems such as cholesterol in addition to the problem of price. (For example, refer nonpatent literature 1, p238-239.)

  For this reason, there is an increasing demand for compound creams and pure vegetative creams as oil-in-water emulsions that are readily available at relatively low prices and have relatively stable quality. In addition, these compound creams and pure vegetative creams are favored by lightening preferences and healthy thinking.

  In general, however, compound creams and pure vegetative creams have a light feeling because they contain little or no milk fat. There was nothing satisfying.

  So far, means for adding a flavor such as milk flavor and vanilla flavor in order to impart a milk feeling or the like to a compound cream or pure vegetative cream has been widely known. (For example, see Patent Document 1, [0059])

  However, such a cream artificially imparted with a milky feeling has a problem that its flavor such as milky feeling and richness is considerably inferior to fresh cream.

  Therefore, an object of the present invention is to provide a new technique capable of imparting a flavor such as a milky feeling or a rich feeling to a compound cream or pure vegetative cream.

  As a result of earnest research to solve the above problems, the present inventors have focused on nonfat concentrated milk as a material for imparting a flavor such as a milky feeling or a rich feeling, and this has been applied to a compound cream or a pure vegetative cream. I tried to add it, but when simply producing a compound cream or pure fat cream, if the non-fat concentrated milk is mixed together with vegetable oils and additives, the physical properties of the resulting cream are not good, It did not become practical.

  Therefore, the present inventors prepared a compound cream or pure fat cream, and then added defatted concentrated milk to it and mixed it to blend with other creams such as fresh cream and compound cream. It has been found that it has excellent flavor and emulsification stability such as milk feeling of raw milk, thick cream, etc., and excellent physical properties such as whipped cream properties, and further has itself excellent flavor and physical properties. Completed the invention.

  That is, the present invention provides an edible cream obtained by emulsifying an oil and fat composition containing at least a vegetable oil and water to obtain an emulsion, and then adding and mixing nonfat concentrated milk to the emulsion. It is.

  Further, the present invention provides an edible cream manufacturing method comprising emulsifying an oil and fat composition containing at least a vegetable oil and water to obtain an emulsion, and then adding and mixing defatted concentrated milk to the emulsion. It is.

  Although the edible cream of the present invention contains vegetable oils and fats, it has excellent flavor and emulsification stability (gel test) such as milk feeling of raw milk, thick feeling of fresh cream, and whipped cream (overrun, artificial flower properties, preservatives). It has excellent physical properties such as moldability and water separation.

  The edible cream of the present invention can impart excellent flavor and physical properties even when blended with other creams such as fresh cream and compound cream.

  Therefore, the edible cream of the present invention can be used as it is or blended with other creams such as fresh creams and compound creams to replace conventional fresh creams and used for confectionery or cooking, or added to beverages. .

  In the present specification, in the "Ministerial Ordinance on Component Standards of Milk and Dairy Products" (hereinafter referred to as "Milk Ordinance"), ingredients other than milk fat are removed from raw milk, milk or special milk. A cream according to type defined as having a milk fat content of 18% by mass (hereinafter simply referred to as “%”) or more is referred to as “fresh cream”. In addition, in the Ordinance of Milk, etc., among the foods whose main ingredients are the name milk etc., only milk fat is used as the fat and further additives such as emulsifiers and stabilizers are used. “A compound cream” is obtained by replacing part of milk fat with vegetable oil, and “pure fat cream” is obtained by replacing all of the fat with vegetable oil. In addition, the edible cream of this invention is classify | categorized into a compound cream or a pure fat cream in the above.

  The edible cream of the present invention is obtained by emulsifying an oil and fat composition containing at least a vegetable oil and water to obtain an emulsion, and then adding and mixing nonfat concentrated milk to the emulsion.
