Abstract

This study aims to investigate the difference in the quality of rice wine fermented with different yeasts (Saccharomyces cerevisiae FBKL2.8022 (Sc) and Wickerhamomyces anomalus FBKL2.8023 (Wa)) by adding Dendrobium officinale (D. officinale). The results showed that the addition of D. officinale improved the physicochemical indices and sensory scores in rice wine and promoted the release of active substances from D. officinale. The addition of D. officinale increased the types and contents of flavor substances in Wa-fermented rice wine and inhibited the generation of flavor substances in Sc-fermented rice wine. Untargeted metabolomics analysis showed that the number of differential metabolites was higher before and after fermentation with D. officinale. The main pathways causing the differences were phenylalanine metabolism and alanine, aspartate and glutamate metabolism (which belong to the amino acid metabolism pathways). This study provides a reference to explore the application value of D. officinale in the fermentation and food industry. [ABSTRACT FROM AUTHOR]

Abstract

Rice, supplemented with Dendrobium officinale, was subjected to cofermentation using Saccharomyces cerevisiae FBKL2.8022 (Sc) and Wickerhamomyces anomalus FBKL2.8023 (Wa). The alcohol content was determined with a biosensor, total sugars with the phenol–sulfuric acid method, reducing sugars with the DNS method, total acids and total phenols with the colorimetric method, and metabolites were analyzed using LC-MS/MS combined with multivariate statistics, while metabolic pathways were constructed using metaboAnalyst 5.0. It was found that the quality of rice wine was higher with the addition of D. officinale. A total of 127 major active substances, mainly phenols, flavonoids, terpenoids, alkaloids, and phenylpropanoids, were identified. Among them, 26 substances might have been mainly metabolized by the mixed-yeasts fermentation itself, and 10 substances might have originated either from D. officinale itself or from microbial metabolism on the newly supplemented substrate. In addition, significant differences in metabolite could be attributed to amino acid metabolic pathways, such as phenylalanine metabolism and alanine, aspartate, and glutamate metabolism. The characteristic microbial metabolism of D. officinale produces metabolites, which are α-dihydroartemisinin, alantolactone, neohesperidin dihydrochalcone, and occidentoside. This study showed that mixed-yeasts cofermentation and fermentation with D. officinale both could increase the content of active substances in rice wine and significantly improve the quality of rice wine. The results of this study provide a reference for the mixed fermentation of brewer's yeast and non-yeast yeasts in rice wine brewing. [ABSTRACT FROM AUTHOR]

Abstract

Fermentation is an effective method for enhancing the biological activity of polysaccharides, but research on its effect on Dendrobium officinal polysaccharides is rare. In this study, the effects of mono-fermentation (Saccharomyces cerevisiae FBKL2.8022, Sc; Wickerhamomyces anomalous FBKL2.8023, Wa) and co-fermentation (Sc+Wa) on the physicochemical properties and bioactivity of Dendrobium officinal polysaccharides were investigated. Meanwhile, the polysaccharide (DOP) obtained from Dendrobium officinale was used as a control. Four homogeneous polysaccharides were obtained by isolation and purification and named DOSCP, DOWAP, DOSWP, and DOP. The results showed that DOSCP, DOWAP, DOSWP, and DOP consisted of mannose and glucose with ratios of 3.31:1, 5.56:1, 2.40:1, and 3.29:1, respectively. The molecular weights (Mws) of the four polysaccharides were 25.73 kDa, 15.01 kDa, 17.67 kDa, and 1268.21 kDa. The antioxidant activity of DOSCP, DOWAP, and DOSWP was better than that of DOP. Additionally, all four polysaccharides were able to reduce the inflammatory response of LPS-induced RAW 264.7 macrophages in the mice without a significant difference. Yeast fermentation significantly reduced the molecular weight and improved the antioxidant activity of Dendrobium officinale polysaccharides, indicating a potential way to improve its antioxidant activity.

148. On the Niho Type Locally-APN Power Functions and Their Boomerang Spectrum

Author

Xie, Xi, Mesnager, Sihem, Li, Nian, He, Debiao, and Zeng, Xiangyong

Abstract

This article focuses on the so-called locally-APN power functions introduced by Blondeau, Canteaut and Charpin, which generalize the well-known notion of APN functions and possibly more suitable candidates against differential attacks. Specifically, given two coprime positive integers $m$ and $k$ such that $\gcd (2^{m}+1,2^{k}+1)=1$ , we investigate the locally-APN-ness property of the Niho type power function $F(x)=x^{s(2^{m}-1)+1}$ over the finite field $\mathbb {F}_{2^{2m}}$ for $s=(2^{k}+1)^{-1}$ , where $(2^{k}+1)^{-1}$ denotes the multiplicative inverse modulo $2^{m}+1$ . By employing finer studies of the number of solutions of certain equations over finite fields, we prove that $F(x)$ is locally-APN and determine its differential spectrum. We emphasize that computer experiments show that this class of locally-APN power functions covers all Niho type locally-APN power functions for $2\leq m\leq 10$ . In addition, we also determine the boomerang spectrum of $F(x)$ by using its differential spectrum, which particularly generalizes a recent result by Yan, Zhang and Li.
