The invention discloses a method for regulating and controlling the strength of casein gel based on tripolyphosphate concentration gradient, belongs to the technical field of food processing and colloidal materials, and is particularly suitable for precise texture regulation and control of high-protein gel in dairy products. In order to solve the problems of poor strength adjustment flexibility and insufficient network structure compactness of casein gel in the prior art, the concentration gradient (0-60mEq / L, and adjacent concentration difference greater than or equal to 5mEq / L) of tripolyphosphate is designed, and the dissociation degree of casein micelles is regulated, so that the integral number of micelle suspension and the proportion of hydrophobic groups are synchronously increased, and the stability of the casein micelle is improved. Finally, directional enhancement of the gel strength and the network compactness is realized. The method specifically comprises the following steps: mixing tripolyphosphate solutions with at least three concentration gradients with casein micelle powder, fully dispersing, adjusting the pH value to be neutral, adding 0.5-3% of an acidifying agent (such as gluconic acid-delta-lactone), and carrying out constant-temperature treatment at 35-40 DEG C to form gel. Dynamic rheology and texture analysis show that the maximum storage modulus of the gel can reach 2596-28000 Pa, the hardness reaches 179.88-2349.19 N, and the performance parameters are in positive correlation with the concentration gradient of tripolyphosphate. The method has the innovativeness that 1) the micelle dissociation degree is controlled through concentration gradient design, and the limitation of single concentration regulation and control is broken through; and 2) the crosslinking density of the gel network is enhanced through double improvement of the volume fraction of dissociated micelles and the proportion of hydrophobic groups.

The application provides a method for removing acetaminophen by using molybdenum powder to strengthen trivalent iron / tripolyphosphate activated molecular oxygen, in particular, molybdenum powder is used to reduce trivalent iron into divalent iron, and the divalent iron and the tripolyphosphate are used to activate molecular oxygen to remove acetaminophen. The addition of molybdenum powder has obvious advantages for trivalent iron / tripolyphosphate activated molecular oxygen, and the removal rate is greatly improved compared with the case without molybdenum powder, and the treatment efficiency of pollutants is improved. The presence of tripolyphosphate can avoid the precipitation of trivalent iron and divalent iron, and can also strengthen the activation of molecular oxygen. Under the condition of medium alkalinity, the system has strong removal capacity for acetaminophen. The morphology of molybdenum powder before and after the reaction and the cycle experiment show that the molybdenum powder has strong stability in the trivalent iron / tripolyphosphate system and can be reused.

The invention discloses application of polyphosphate kinase BsPPK in synthesis of ATP (adenosine triphosphate). The amino acid sequence of the polyphosphate kinase BsPPK is as shown in SEQ ID NO. 1. In specific application, adenosine diphosphate or adenosine monophosphate is used as a phosphate receptor, polyphosphate is used as a phosphoric acid donor, and ATP is synthesized under the action of polyphosphate kinase BsPPK. The polyphosphate is selected from tripolyphosphate or hexametaphosphate. The invention also discloses an application of the polyphosphate kinase BsPPK in the synthesis of uridine diphosphate-galactose, and an application of the polyphosphate kinase BsPPK in the synthesis of lactosyl-N-tetrasaccharide. According to the method, the ATP is synthesized and regenerated by utilizing the polyphosphate kinase BsPPK, so that the reaction cost of UDP-Gal and LNT in-vitro synthesis routes is greatly reduced. The method has important significance on ATP regeneration and synthesis of UDP-Gal and galactosyl lactose derivatives, and has a wide application prospect.
