Abstract

The invention relates to a crystallization technical method for industrially producing trehalose. According to the crystallization technical method for industrially producing the trehalose, in industrial production, by utilizing the characteristics of trehalose mixed sugar liquid, crystalline trehalose is produced quickly and largely by adopting the following four steps of (1), performing high-temperature low-pressure sugar boiling: quickly concentrating the trehalose mixed sugar liquid until a highest critical concentration at which a crystal is separated out is reached; (2), quickly cooling and crystallizing: putting the trehalose mixed sugar liquid into a crystallization tank, and carrying out the quick cooling and crystallization in a natural condition without adding any eluting agent and crystal seed; (3), replenishing an appropriate amount of water for dissolving heterogeneous sugar: when the trehalose mixed sugar liquid is cooled to be at a room temperature and the crystal is completely separated out, adding cold pure water in a certain proportion into the trehalose mixed sugar liquid, so as to dissolve most of the heterogeneous sugar on the surface of the crystal; (4), centrifuging an obtained mixture at a low speed, and naturally air-drying an obtained product, so as to obtain high-purity crystalline trehalose, and completely recycling and reusing centrifuged mother liquid. The method provided by the invention has the advantages of being short in period, high in efficiency, low in energy consumption, free from pollution and zero in release; the product made by the crystallization technical method is safe and a user can be unworried.

Description

technical field [0001] The invention relates to the technical field of trehalose, in particular to a crystallization process for industrial production of trehalose. Background technique [0002] Trehalose is a natural disaccharide composed of two molecules of glucose connected by α-1,1 glycosidic bonds. It has excellent water retention, antifreeze, non-reducing and thermal stability. It is widely used in cosmetics, food and medicine. It is widely used in health care products. Trehalose has been recognized all over the world as a natural and safe food or food additive, and has a large demand in bakery products and frozen seafood products. Trehalose is added to more than half of the moisturizing skin care cosmetics on the market; especially for new skin care cosmetics, trehalose is gradually replacing traditional glycerin as the main ingredient. In medicine and health care products, trehalose can effectively protect biological cells under ultra-low temperature freezing; ...
