Summary: | Cocoghurt is a novel fermentation product with coconut milk as the main raw
ingredient. In this study, the starter concentration and fermentation time on the viability of
lactic acid bacteria (LAB) and the fatty acid profile and quality of the cocoghurt were
examined. Lactobacillus casei sub sp. casei R-68 and Streptococcus thermophilus were used as
starter cultures. The results showed that 3.0% of the L. casei subsp. casei R-68 and S.
thermophilus starters resulted in the optimal growth of LAB. Fermentation time significantly
affected pH, total lactic acid, total LAB, and protein content but did not significantly influence
ash, moisture, fat, and total solid content. The duration of fermentation also did not
significantly affect the fatty acid profile. The probiotic cocoghurt fatty acid profiles consisted
mainly of medium-chain saturated fatty acids followed by long-chain saturated fatty acids and
finally unsaturated fatty acids. Cocoghurt produced using skim milk 3.0% starter and
fermentation time for 10 hours had the characteristic of being slightly white, tasting sour and
sweet, with an aroma of coconut milk; the texture was relatively thick and preferred by the
panelists. |
