Abstract

The invention discloses a high-efficiency composite clarifying agent used for clarification and decolorization of a sugar liquid. The high-efficiency composite clarifying agent is composed of the following components in parts by weight: 100 to 200 parts of modified calcium phosphate, 2 to 5 parts of polyphenol oxidase and 2 to 5 parts of pectinase. The preparation method for the composite clarifying agent comprises the following steps: weighing the polyphenol oxidase and the pectinase according to the amounts described in the formula, dissolving the weighed polyphenol oxidase and pectinase into a phosphate buffer solution so as to obtain an enzyme mixed solution, then weighing the modified calcium phosphate according to the amount described in the formula, adding the modified calcium phosphate into the enzyme mixed solution under the condition of stirring, carrying out oscillating adsorption at 10 to 20 DEG C for 2 to 6 hours, and carrying out drying under a vacuum condition so as to obtain the high-efficiency composite clarifying agent used for clarification and decolorization of the sugar liquid. The high-efficiency composite clarifying agent provided by the invention is used forclarification and decolorization of the sugar liquid, can improve the efficiency of a decolorization procedure in sugar preparation, and reduces the production cost of sugar preparation.

Description

technical field [0001] The invention belongs to the technical field of sugar decolorization technology, and in particular relates to a high-efficiency composite clarifying agent for clarifying and decolorizing sugar liquid. Background technique [0002] Sugar is an indispensable sweetener and nutrient in human life. The annual consumption of sugar per capita in the world is about 20kg. Sugars such as white sugar and brown sugar that we often see in our lives are extracted from plants and fruits with high sugar content. , produced through a complex process. At present, there are two main sugar production processes at home and abroad: one is to directly produce white sugar from sugarcane or sugar beet, that is, farmland white sugar, and the other is to make raw sugar first, and then dissolve and refine it to make white sugar. With the increase of sugar consumption in my country, the domestic direct production of farmland white sugar can no longer meet the consumption demand. ...
