The addition of JA resulted in an initial pH of 7.14, which decreased to 3.59 after 36 h of fermentation, compared to a decrease from 7.51 to 5.28 in the control sample. Similarly, the titratable acidity increased to 0.89 g/L in the JA-based sample versus 0.62 g/L in the control, with no statistically significant difference observed in the acidification rate (p > 0.05). The JA-based water kefir exhibited significantly higher LAB populations, with <em>Lactobacillus</em> sp. and <em>Lactococcus</em> sp. counts reaching 8.52 log CFU/mL and 7.14 log CFU/mL, respectively, compared to 5.65 log CFU/mL and 5.57 log CFU/mL in the control. DGGE analysis confirmed this trend by revealing a more diverse LAB community in the JA-based sample at the end of fermentation. Notably, <em>Leuconostoc mesenteroides</em> emerged as the dominant LAB species in JA-based water kefir, representing approximately 65% of the LAB population at the end of fermentation, with its count reaching 5.54 log CFU/mL out of the total 8.52 log CFU/mL for <em>Lactobacillus</em> sp. Regarding chemical constituents, the principal volatile compounds identified in JA-based water kefir included ethyl acetate, 3-Methyl-1-butanol, Phenethyl alcohol, nonanoic acid, capric acid, and myristic acid. Furthermore, the addition of JA to water kefir significantly increased the presence of prebiotic compounds such as inulin and fructooligosaccharides (FOS), as evidenced by the fructan content, which reached 0.546 g/100 mL during fermentation. A strong positive correlation was observed between the fructan content and LAB growth during fermentation (Pearson's r = 0.92 for Lactobacillus sp. and r = 0.89 for total LAB counts), demonstrating the impact of JA on the fermentation process and microbial proliferation. Principal Component Analysis (PCA) revealed a significant correlation between the utilization of JA as a substrate and the duration of fermentation. In conclusion, Jerusalem artichoke, with its fructan content reaching 0.546 g/100 mL, serves as a significant substrate for water kefir fermentation, enriching the beverage with inulin-type fructans and, combined with enhanced LAB proliferation, establishing its symbiotic nature.</div></div>","PeriodicalId":48594,"journal":{"name":"International Journal of Gastronomy and Food Science","volume":"39 ","pages":"Article 101104"},"PeriodicalIF":3.2,"publicationDate":"2025-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143153030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The liquid fermentation method for making fermented large yellow croaker sauce (LYCS) is a new attempt to obtain a unique fermented flavor more efficiently based on the traditional fermentation method. Hongqu lees impart unique flavors to fermentation, and different amounts of Hongqu lees added lead to fermentation systems with different initial physicochemical and microbiological properties. Microwave pretreatment before fermentation (MWP) was introduced as a key innovation technique aimed at reducing undesirable microorganisms in the fermentation raw material and enhancing the release of flavors in the fermentation. This study investigated the effects of MWP and different levels of Hongqu lees addition on the physicochemical characteristics and microbial composition of LYCS. MWP increased the total acid (TA), total nitrogen (TN), and trichloroacetic acid (TCA) - soluble peptides contents. Histamine content was significantly reduced by increasing the Hongqu lees addition to L2 (1:0.2 ratio of fish pulp to Hongqu lees). In terms of taste profile, MWP effectively reduces bitterness but also leads to a loss of umami. The main volatiles detected in LYCS were esters and alcohols. Without MWP, LYCS emitted unpleasant volatile odors in the L1 and L2 experimental conditions (1:0.1 and 1:0.2), and MWP effectively reduced these undesirable effects. The dominant bacteria identified in LYCS were <em>Lactobacillus</em>. MWP eliminated <em>Lactococcus</em>, which was derived from large yellow croaker and had a negative effect on LYCS. Moreover, an increase in Hongqu lees additions led to a reduction in the relative abundance of <em>Clostridium</em>. The comprehensive results showed that MWP improved the quality of LYCS, and the optimal addition of Hongqu lees was observed at the L2 level (1:0.2) following MWP.
