We produce maltodextrin using a continuous and stable system in which cyclodextrin is passed through the immobilized enzyme reactor. Maltodextrin(G6, G7, G8), which is produced according to the type of substrate, is purified to a high purity of 98% or more, and is dried and processed as a powder product. The maltodextrin produced through the immobilized enzyme system is used to synthesize high purity linear maltodextrin which is the core product of our company. We synthesize linear maltodextrins of various lengths using specific enzymes, and sell the pure long-chain linear maltodextrins with a maximum degree of polymerization(DP) of 24 through our outstanding technology that only isolates linear maltodextrins of a certain length.
This high-purity, long-chain maltodextrin is a product that has not been found in the carbohydrate materials market until now and is developed and produced by CarboExpert Inc. based on our solid technology.
Our research team has a long experience in the pathway of carbohydrate synthesis of microorganisms. BAPS, which is synthesized in the self-developed strain, is generally composed of shorter lengths of branches than polysaccharides or amylopectin. This results affects the digestion efficiency, and BAPS can be utilized as a slow digestible material. In order to prove the low digestion efficiency of BAPS, the hydrolysis kinetics using amyloglucosidase derived from Aspergillus niger, human pancreatic α-amylase, and pig pancreatic α-amylase was carried out. This experiment showed that the kcat / Km value of BAPS was 2 times lower than that of amylopectin. We also confirmed the immunostimulating activity of BAPS.
We also produce slowly digestible starch using several kinds of microbial enzymes. As a verification test for our technology of slowly digestible starch production, amylopectin, a constituent of starch, is reacted with each of the enzymes to modify as a new type of amylopectin. The digestion efficiency of the modified amylopectin was analyzed based on the hydrolysis kinetics using pig’s pancreatic α-amylase. As a result, it was confirmed that kcat/Km value decreased by 1/4 as compared with amylopectin. This means that the modified amylopectin shows about 4 times lower digestion efficiency than general amylopectin. Based on this study, we have secured our own production technology of the slowly digestible starch as a food material.
