Enhancement of γ-aminobutyric acid in fermented cucumbers.

The effects of brine acidification, glutamate addition, and starter culture on γ-aminobutyric acid (GABA) content of fermented cucumber were investigated. GABA is a nonprotein amino acid with antihypertensive, antianxiety, and immunomodulatory properties. It is produced during cucumber fermentation but is limited by the low intrinsic concentration of free glutamate.

Biomarkers of Metabolic Adaptation to High Dietary Fats in a Mouse Model of Obesity Resistance.

Obesity-resistant (non-responder, NR) phenotypes that exhibit reduced susceptibility to developing obesity despite being exposed to high dietary fat are crucial in exploring the metabolic responses that protect against obesity. Although several efforts have been made to study them in mice and humans, the individual protective mechanisms are poorly understood. In this exploratory study, we used a polygenic C57BL/6J mouse model of diet-induced obesity to show that NR mice developed healthier fat/lean body mass ratios (0.

Baked sweetpotato textures and sweetness: An investigation into relationships between physicochemical and cooked attributes.

Sweetpotato varieties vary greatly in perceived textures and sweetness. This study identified physicochemical factors that influence these attributes in cooked sweetpotatoes. Fifteen genotypes grown on three plots were baked and evaluated by a trained descriptive sensory analysis panel for sweetness and 13 texture attributes.

A sensory lexicon to characterize the quality of fresh and preserved peppers.

Pepper fruits (Capsicum annuum) are economically important commodities worldwide due to their unique sensory profiles and rich antioxidant properties. With ongoing research efforts in optimizing the production and processing of peppers, there is a need for a standardized tool to evaluate the quality of peppers and pepper products. The objective of this work was to develop a sensory lexicon to characterize fresh and preserved peppers.

, autochthonous to cucumber fermentation, is unable to utilize citric acid and encodes for a putative 1,2-propanediol utilization microcompartment.

The metabolic versatility of , a heterofermentative lactic acid bacterium, could benefit environmentally compatible and low salt cucumber fermentation. The biodiversity of autochthonous to cucumber fermentation was studied using genotypic and phenotypic analyses to identify unique adjunct cultures. A group of 131 isolates autochthonous to industrial fermentations was screened using rep-PCR-(GTG) and a fermentation ability assay under varied combinations of salt (0 or 6%), initial pH (4.
