Description

Natural yellow oil embedding powder and preparation method thereof

Technical Field

The application relates to the field of food processing, in particular to natural yellow oil embedding powder and a preparation method thereof.

Background

The natural butter is semi-solid grease which is separated from milk and is formed after pasteurization and freezing, has rich milk fragrance and butter fragrance, is natural animal grease with rich nutritive value, and is widely applied to baked food, solid beverage, various drinks and seasonings, but because the natural butter needs to be frozen for storage and cold chain transportation, the natural butter needs to be thawed and the like in the using process, and is more complicated.

Therefore, instead of butter, butter powder is a white to creamy powder product obtained by mixing high-purity butter and high-quality maltodextrin materials and spray-drying, and in most cases, butter powder is prepared by removing water from standard portions of butter. This process does not affect the butter fat content, since the fat is naturally not melted in water. The dehydrated final product is a multipurpose powder which can be used in different food preparations. It is difficult to mix the butter with other dry materials such as flour, soda ash, baking powder and salt. The butter powder is easy to be fully mixed with flour and the like, and has higher nutrition.

At present, in the production engineering of butter powder, antioxidants such as tea polyphenol are usually added, or butter essence is added into vegetable oil or hydrogenated vegetable oil for blending, and then maltodextrin raw materials are used for mixing and spray drying are carried out to form the butter powder. The butter powder obtained by the method has a flavor and nutrition far different from those of natural butter, and the taste is affected by adding antioxidant of tea polyphenols. Further research is therefore required.
