In the preparation of a series of Ce_(0.8)Zr_(0.2)O_(y)catalysts catalyzing the removal of formaldehyde,BET,H2-TPR,IR,sEM,XPs,and XRD were used to characterize the catalyst,and the influence of humidity on the catalyst activity was studied by adjusting the humidity during the *** experimental results showed that the formaldehyde removal rate increased with the increase of *** the humidity was higher than 50%,the formaldehyde removal rate decreased by 3%over that when the humidity was 50%.The characterization results showed that humidity facilitated the activation of oxygen and the formation of hydroxyl groups,which both promoted the formation and oxidative decomposition of intermediates and prevented the deposition of intermediates that clogged the pores,allowing more formaldehyde to be adsorbed and oxidized,which increased the activity of the *** provides new mechanistic evidence for the oxidation of formaldehyde and helps in the development of relatively low-cost materials for formaldehyde purification.

Adaptability of two cellulase producing strains Bacillus sp. sH and Aspergillus oryzae y21 in whole wheat dough and impact on the quality of whole wheat bread

Compared to refined wheat flour， whole wheat flour contains higher nutrients， but its high content of dietary fiber can have a significant impact on the quality of the final product. Therefore， how to enable consumers to obtain health benefits from whole wheat flour and improve the processing performance of whole wheat products has become a concern. The purpose of this study is to apply two strains Bacillus sp. sH and Aspergillus oryzae y21 with cellulase production capacity and study their adaptability in whole wheat dough. The results indicate that the addition of cellulase-producing strains enhanced the acid production ability of whole wheat dough， rapidly reduced its pH value and insoluble dietary fiber content， and significantly increased the water-soluble arabinoxylan and water-soluble dietary fiber content. During the fermentation process， the viscoelasticity of the dough decreased， free sulfhydryl content increased， wet gluten content decreased， and the degree of reduction was consistent with the degree of acidification. Moreover， the proteolytic activity of the dough was increased， and the hydrolysis of gliadin was the most extensive. Bacillus sp. sH showed a higher advantage and has been used in whole wheat bread making. Increasing the proportion of strain sH in whole wheat bread can improve the structural characteristics and texture of the bread. When sH (5 × 107CFU/g) is added to whole wheat bread， its hardness， elasticity， chewiness， and resilience can be similar to those of bread made from control group wheat flour， far exceeding that of whole wheat bread without adding sH. The addition of cellulase producing strains has obvious advantages in the development of whole-wheat dough， and also promote the development of whole wheat fermented foods as staple foods.
