Problems solved by technology

However, in the current preparation method of trehalose, the particle size of the selected seed crystals is not uniform, and during the crystallization process, the cooling rate of cooling crystallization is set unreasonably, resulting in small and uneven particles of trehalose, and the particle size is generally 90% below 20 mesh. More than 50% under 40 mesh, more than 30% under 60 mesh; it is inconvenient to use when mixing with salt and sugar, and it is easy to cause uneven proportioning, and the usage amount cannot be accurately grasped, resulting in unstable product quality

Abstract

The invention discloses a method for preparing large-particle trehalose, which specifically includes the following steps: (1) preparation of starch milk, (2) liquefaction, (3) double enzymatic hydrolysis, (4) filtering to remove protein, (5) decolorization, (6) ) desalination, (7) purification, (8) concentrated crystallization, (9) separation and drying to obtain finished products; the advantages of the present invention are that the prepared product particles are large and uniform, with a particle size of 40 mesh or more than 35%, and 40 mesh or less of 65% or more. %, easy to use, when compounding with salt or sugar, the proportion can be accurately controlled, so that the saltiness of salt compound products is more uniform, and the sweetness and Maillard reaction of sugar compound products are reduced. It can improve the quality of compound products.

Description

Technical field: [0001] The invention relates to a method for preparing trehalose, in particular to a method for preparing large-particle trehalose. Background technique: [0002] Trehalose, also known as sucrose, mushroom sugar, etc., is a safe and reliable natural sugar. Trehalose has a magical protective effect on organisms. Trehalose can form a unique protective film on the cell surface under harsh environmental conditions such as high temperature, high cold, high osmotic pressure, and dehydration, effectively protecting protein molecules from denaturation and inactivation. , so as to maintain the life process and biological characteristics of living organisms. However, other sugars such as sucrose and glucose in nature do not have this function. This unique functional property makes trehalose not only an excellent active protectant for protein drugs, enzymes, vaccines and other biological products, but also an important ingredient for maintaining cell activity and moi...
