Abstract
As food trends evolve towards sustainable, healthy, and mildly processed products, it is essential to consider new food sources, which contribute to positive changes in the food industry and originate interesting new products. For the tomato industry, where only completely red tomatoes are used, unripe and non-red tomatoes constitute an important by-product, with important losses in the field of a perfectly edible vegetable food source. To give value to this unripe tomato, a fermentation with a consortium of lactic acid bacteria and yeast was previously optimized, originating an acidic pulp with optimized nutritional characteristics and great potential for salad dressing development. Pulp's texture was improved with two hydrocolloid systems: 0.5 g/100 g of xanthan gum; and a mixed system of xanthan gum and kappa-carrageenan (0.1 g/100 g each). After rheology optimization, spices and condiments were added to the thickened fermented pulp, and promising tasty sauces were obtained. These sauces were presented to a consumers' panel, with good acceptance. The production of these new healthy sauces aims to mitigate unripe tomato waste, adding value to the tomato industry by using a major industrial by-product.

Wang LH, Qu WH, Xu YN, Xia SG, Xue QQ, Jiang XM, Liu HY, Xue CH, Wen YQ. Developing a High-Umami, Low-Salt Soy Sauce through Accelerated Moromi Fermentation with Corynebacterium and Lactiplantibacillus Strains. Foods 2024; 13:1386. [PMID: 38731757 PMCID: PMC11083161 DOI: 10.3390/foods13091386] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2024] [Revised: 04/09/2024] [Accepted: 04/14/2024] [Indexed: 05/13/2024] Open
Abstract
The traditional fermentation process of soy sauce employs a hyperhaline model and has a long fermentation period. A hyperhaline model can improve fermentation speed, but easily leads to the contamination of miscellaneous bacteria and fermentation failure. In this study, after the conventional koji and moromi fermentation, the fermentation broth was pasteurized and diluted, and then inoculated with three selected microorganisms including Corynebacterium glutamicum, Corynebacterium ammoniagenes, and Lactiplantibacillus plantarum for secondary fermentation. During this ten-day fermentation, the pH, free amino acids, organic acids, nucleotide acids, fatty acids, and volatile compounds were analyzed. The fermentation group inoculated with C. glutamicum accumulated the high content of amino acid nitrogen of 0.92 g/100 mL and glutamic acid of 509.4 mg/100 mL. The C. ammoniagenes group and L. plantarum group were rich in nucleotide and organic acid, respectively. The fermentation group inoculated with three microorganisms exhibited the best sensory attributes, showing the potential to develop a suitable fermentation method. The brewing speed of the proposed process in this study was faster than that of the traditional method, and the umami substances could be significantly accumulated in this low-salt fermented model (7% w/v NaCl). This study provides a reference for the low-salt and rapid fermentation of seasoning.

Abstract
The inoculation of S. cerevisiae can address the excessive acidity in Suanyu, but its influence on the microbial community structure has not been documented. In this study, the microbiota succession, and metabolites of Suanyu with the inoculation of acid-reducing S. cerevisiae L7 were explored. The findings revealed that the addition of S. cerevisiae L7 elevated the pH, and decreased the microbial α-diversity. In Suanyu, the dominant bacterial genera were Lactiplantibacillus and Bacillus, while the dominant fungal genera were Meyerozyma and Saccharomyces. Following the inoculation of S. cerevisiae L7, the relative abundance of Lactiplantibacillus decreased from 21 % to 13 %. Meanwhile, the growth of fungi such as Meyerozyma and Candida was suppressed. The rise in Saccharomyces had a significant impact on various pathways related to amino acid and carbohydrate metabolism, causing the accumulation of flavor compounds. This study sheds more lights on the methods for manipulating microbial community structure in fermented food.

Abstract
Abstract
Probiotic fermented fruit juice could improve intestinal health with better sensory attributes. The effects of fermentation conditions on flavor quality of fermented bayberry juice were compared through microbial viability and sensory evaluation. Fermentation by combined Streptococcus thermophilus (ST) and Lactobacillus acidophilus (LA) resulted in higher microbial viability and sensory evaluation scores. The fermentation conditions were optimized by orthogonal experimental design and TOPSIS analysis (ST and LA in a 3:1 ratio; 0.6% w/v inoculation; fermentation time, 48 h, at 37℃; 10% w/v added sucrose). Fermentation under these conditions decreased the anthocyanin content of the juice, maintained the total phenolic content and slightly decreased the antioxidant capacity. Fermentation reduced aroma volatiles from 42 in fresh juice, to 33, determined by GC-MS-O, the aldehyde content decreased and the alcohol content increased. Lactic acid fermented bayberry juice by ST and LA produced a beverage with desirable consumer attributes, combining the health benefits of fresh juice and probiotics.

Selection of Autochthonous LAB Strains of Unripe Green Tomato towards the Production of Highly Nutritious Lacto-Fermented Ingredients. Foods 2021; 10:foods10122916. [PMID: 34945467 PMCID: PMC8700740 DOI: 10.3390/foods10122916] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2021] [Revised: 11/09/2021] [Accepted: 11/18/2021] [Indexed: 12/15/2022] Open
Abstract
Lactic fermentation of unripe green tomatoes as a tool to produce food ingredients is a viable alternative for adding value to industrial tomatoes unsuitable for processing and left in large quantities in the fields. Fermentation using starter cultures isolated from the fruit (plant-matrix adapted) can have advantages over allochthonous strains in obtaining fermented products with sensory acceptability and potentially probiotic characteristics. This paper details the characterisation of the unripe green tomato lactic microbiota to screen LAB strains for use as starter cultures in fermentation processes, along with LAB strains available from INIAV's collection. Morphological, biochemical (API system), and genomic (16S rDNA gene sequencing) identification showed that the dominant LAB genera in unripe green tomato are Lactiplantibacillus, Leuconostoc, and Weissella. Among nine tested strains, autochthonous Lactiplantibacillus plantarum and allochthonous Weissella paramesenteroides showed tolerance to added solanine (200 ppm) and the best in vitro probiotic potential. The results indicate that the two LAB strains are promising candidates for manufacturing probiotic fermented foods from unripe green tomatoes.
