Objectives: To obtain a stable Rhodotorula mucilaginosa with excellent aroma production for enhancing the flavor quality of Huangjiu fermentation. Methods: The optimal fermentation strains were selected from nine isolates by analyzing tolerance， β-glucosidase activity and aroma production characteristics， and co-fermented with Saccharomyces cerevisiae to investigate the effect of co-fermentation on the flavor quality of Huangjiu. This study further used headspace solid-phase microextraction (SPME) and gas chromatography-mass spectrometry (GC-MS) in combination with sensory evaluation and physicochemical indexes to investigate the effect of co-fermentation on the flavor quality of Huangjiu. Results: Nine strains of R. mucilaginosa were identified and screened. All strains grew well under the conditions of 10-35 ℃ and pH 5.0-6.5， with good low temperature and acid tolerance and high β-glucosidase enzyme activity (253.7-492.2 U/mL)， and the ethanol tolerance of different strains varied greatly. The content of alcohol， aldehyde， acid and ester in the fermentation broth of JH-6 strain was significantly higher than that of other strains， and it had good aroma-producing performance. The co-fermentation of R. mucilaginosa JH-6 and S. cerevisiae with Huangjiu conformed to the national standard GB/T 13662—2018 of Huangjiu， and compared with the Huangjiu produced without inoculation of JH-6， the alcoholic strength was lowered， the content of ester was increased， the texture was soft and harmonious， the aroma of flowers and fruits was prominent， and the flavor quality was obviously improved. The flavor quality of the wine was significantly improved with the prominent aroma. Conclusion: In this study， R. mucilaginosa was systematically screened and evaluated， and a strain JH-6 with good tolerance and optimal aroma production characteristics was obtained， and the flavor quality of Huangjiu was improved by co-fermentation of this bacterium with S. cerevisiae， and the study provides technological support for the application of R. mucilaginosa in the fermentation of Huangjiu.

Objectives: The efficient release of bioactive peptides (BPs) from bovine milk proteins is of great significance. This study aimed to explore the potential of using the soluble proteinase of lactic acid bacteria (LAB) for production of BPs. Methods: A LAB strain exhibiting high proteolytic activity was screened and identified. The gene encoding the proteinase in the selected LAB was amplified via PCR and then modified by removing the sequence encoding the cell-wall-associated region， enabling it to be a soluble protein. Subsequently， the modified gene prtB3 was cloned and expressed in the food-grade expression strain Lactococcus lactis NZ9000. After purification， a comprehensive evaluation was conducted on the enzymatic properties of the recombinant proteinase PrtB3 and the biological activities of the hydrolysates resulting from casein degradation. Results: The screened LAB strain was identified as Lactobacillus delbrueckii subsp. lactis. A soluble， secreted， C-terminally Myc and His-tagged derivative PrtB3 was constructed and expressed in Lactococcus lactis via the NICE■ Expression System. Compared with the wild-type proteinase， PrtB3 demonstrated a significant expansion in substrate specificity. It was proteolytically active in the hydrolysis of α-， β-， and κ-casein. Regarding biological activity， the casein hydrolysate produced by PrtB3 showed remarkable angiotensin-converting enzyme (ACE) inhibitory activity. The maximum ACE inhibition rate reached 78%， which was twice that of the hydrolysate produced by the wild-type proteinase. The half-maximal inhibitory concentration (IC50) was 1.69 mg/mL， and the ACE inhibitory activity remained stable over an 8-week period. Furthermore， the enzymatically produced hydrolysate showed antimicrobial activity against Staphylococcus aureus and Escherichia coli. Conclusions: In this study， the soluble proteinase PrtB3 was successfully cloned and expressed. It effectively enhanced the degradation of casein and significantly improved the biological activity and stability of the casein hydrolysate. PrtB3 demonstrated great potential in producing BPs by degrading casein， providing a novel approach for the preparation of bioactive peptides.

Objective: Correlation between alkali treatment process and carrageenan gel quality and prediction model were studied. Method: Carrageenan was extracted from Eucheuma muricatum by alkali extraction method， and a reliable and measurable model was established to predict the gel properties and molecular characteristic structure of carrageenan under different alkali treatment process conditions using artificial neural network (ANN) model. Results: Artificial neural network model fit the total set with R2 = 0.991 better than the multivariate linear model (MLR)， with mean absolute percentage errors (MAPEgel strength = 1.71%， MAPEmolecule = 18.84%， and MAPEsulphate group = 1.91%， MAPE3，6-endoethergalactose = 3.68%) are lower than the MLR model. In addition， in actual production， when the key process parameters of alkali treatment (temperature， time， and concentration) were 65 ℃， 6 h， and 10%， the gel strength of carrageenan was measured to be 614.32 g/cm2， and the gel strength of carrageenan was predicted to be 617.13 g/cm2 by the constructed prediction model of the correlation between carrageenan processing alkali treatment and its gel quality. The results show that the predicted value of the model is close to that of the actual production. Conclusion: The prediction performance of ANN model is better than that of multivariate linear model， and ANN model is more accurate than MLR model in predicting carrageenan gel properties and molecular characteristic structure. This study provides a technical reference for the intelligent and precise manufacturing of carrageenan high-quality products， so as to expand the application of carrageenan in biomedicine and other fields.

Objective: To explore the effect of Na+/K+ in the intestinal environment on the interaction between soy hull polysaccharide (SHP) and intestinal mucus， and its effect on the diversity of intestinal flora. Methods: Molecular docking and molecular dynamics simulation were used to analyze the main binding force and complex stability of the target protein and soybean seed coat polysaccharide after Na+/K+ treatment. The effects of SHP and mucin on the changes of OTU and species abundance of intestinal flora after Na+ treatment was detected by 16S rDNA genomics. Results: The main force of SHP binding to mucin after Na+/K+ treatment was hydrogen bond. Within 100 ns， the RMSD value， RSMF value， Rg value and the number of hydrogen bonds of the complex structure fluctuated slightly. The secondary structure β-sheet of mucin mainly existed in anti-parallel mode after Na+ treatment， while the secondary structure β-sheet of mucinmainly existed in parallel mode after K+ treatment. The binding free energy [(196.7±26.7) kJ/mol] and the contribution of amino acid residues (18.18 kJ/mol) of SHP to mucin after Na+ treatment were greater than those after K+ treatment [(158.5±26.7) kJ/mol and 10.63 kJ/mol， respectively]. In the presence of Na+， the diversity of intestinal flora was up to 284 OTUs when SHP was used as a substrate for 8 h， and the abundance of various dietary fiber degrading bacteria was increased， and the abundance of Escherichia coli-Shigella was decreased. At the same time， the abundance of Bifidobacterium and Lactobacillus was also decreased. Conclusion: After Na+ treatment， the binding ability and stability of SHP and mucin are higher， and the diversity and abundance of intestinal flora are affected. Na+ treatment has a potential effect on the whole intestinal function of dietary fiber.

In recent years， probiotic products have been widely applied in the food， medical， and healthcare industries. However， maintaining strain viability during industrial production， transportation， and storage remains a challenge. Currently， enterprises and research institutions primarily employ dehydration to maintain probiotic activity. Among these methods， vacuum freeze-drying has become the mainstream choice as it can maintain strain viability to the greatest extent with low energy consumption and a simple process. Nevertheless， vacuum freeze-drying still causes damage to the cell membranes， enzymes， and DNA of probiotics， reducing their activity during application. This paper summarizes the latest research progress in methods to resist freeze-drying damage in probiotics， namely by regulating media components and cultivation conditions， stress pre-treatment， optimizing centrifugation conditions， adding cryoprotectants， and optimizing freeze-drying processes to enhance the freeze-drying resistance of strains and reduce freeze-drying damage. This work aims to provide a theoretical reference for the preparation of high-viability probiotic products.

This study aimed to enhance the quality of pineapple pomace wine and achieve high-value utilization of agricultural byproducts. Through plate separation combined with morphological identification for strain isolation and purification， a stepwise screening strategy integrating sensory evaluation with electronic nose analysis for preliminary screening and tolerance assays for secondary screening was implemented. A superior strain (No.50) with both exceptional environmental tolerance and aroma-producing properties was successfully isolated. This strain exhibited robust growth under extreme conditions (glucose 350 g/L， SO₂ 300 mg/L， pH 2.0， ethanol 9%). Molecular identification via ITS sequencing confirmed it as Saccharomyces cerevisiae， designated as Saccharomyces cerevisiae FOSU-QQT. Comparative fermentation experiments demonstrated that pineapple pomace wine inoculated with FOSU-QQT showed a 27.07% increase in total ester content compared to natural fermentation， with significant enrichment in characteristic aroma compounds including ethyl octanoate， ethyl decanoate， ethyl hexanoate， isoamyl acetate， and ethyl laurate (P＜0.05). The study verifies that this strain effectively enhances the aromatic profile of fruit wines， providing a theoretical foundation for developing novel aroma-enhancing fermentation agents. These findings offer practical implications for the resource utilization of agricultural processing byproducts.
