Abstract

Aims: To investigate the fermentation parameters physico-chemical characteristics and to conduct sensory evaluation to assess the acceptability of the fermented chia seeds. Study Design: Experimental study involving the fermentation of chia seeds with varying combinations of water, curd, and honey. Assessment of fermentation parameters and physico-chemical characteristics. Microbiological analysis, LAB isolation, and measurement of TSS, acidity, and pH. Sensory evaluation to determine the acceptability of the fermented chia seeds. Place and Duration of Study: The study undertaken during 2020-23 in the Department of Food Science and Nutrition, University of Agricultural Sciences, GKVK, Bangalore, Karnataka. Methodology: Chia seeds subjected to different fermentation treatments involving combinations of water, curd, and honey. Microbiological analysis conducted to assess microbial populations. Isolation of lactic acid bacteria (LAB) to study their presence. Measurement of total soluble solids (TSS), acidity, and pH to evaluate physico-chemical changes during fermentation. Sensory evaluation performed to determine consumer acceptability. Results: Fermentation treatments showed significant differences in soluble solids ranged (1.63 to 8.10), pH (1.87 to 3.87), and acidity, showcasing organic acid content, notably lactic acid (0.04 to 0.23), oxalic acids (0.04 to 0.23), citric acid (0.09 to 0.50), maleic acid (0.06 to 0.35) and succinic acid (0.05 to 0.30. Fermented white chia with distilled water + curd+ honey (FWC3) and Fermented black chia with distilled water + curd+ honey (FBC3) had the statistically higher mean sensory scores.
