Abstract

The invention relates to a preparation method for a solid decolorizer for decolorizing flavored fat, and belongs to the technical field of edible fat processing. The preparation method for the solid decolorizer for the flavored fat is characterized by comprising the following steps: (1) alkalization of floridin: taking 100 parts by weight of floridin, putting the floridin in a container with a stirring device and a heating device, adding 300 parts by weight of water for suspension and dispersal under the circumstance of stirring the floridin and the water, heating the mixture of the floridin and the water to be 40-70 DEG C, dripping strong alkali dilute solutions for alkalization, controlling floridin suspension liquid to reach a specified pH value, and continuing stirring the floridin suspension liquid for 30-60 minutes; (2) solid-liquid separation / drying: separating the suspension liquid, drying and dehydrating obtained solids so as to obtain the solid decolorizer for the flavored fat. The solid decolorizer which is obtained by the method is used for decolorizing the fat, the purposes of decolorizing the fat and greatly improving the flavor of refined fat are achieved at the same time, the method is simple, convenient and effective, and the method is convenient for implementation and popularization.

Description

technical field

[0001] The invention relates to a preparation method of a solid decolorizing agent used for decolorizing flavor oils, and belongs to the technical field of edible oil processing. Background technique

[0002] Decolorization is an essential and important process for refining dark oils, not only to meet the good appearance requirements of market products, but also to ensure the internal requirements of food safety. At present, for the decolorization of dark oil, the main method is to use activated clay and oil to mix adsorption reaction under the condition of vacuum degree above 8KPa and temperature at 90-110°C. From long-term production practice experience, activated clay is used to decolorize dark oil with good flavor. Although dark oil can be refined into light-colored oil, it will seriously damage the flavor of oil and produce a strong earthy smell. Therefore After decolorization, no matter whether the oil peroxide value exceeds the standard, vacuum deodor...
