Abstract
According to WHO, in 2016 around 13% of the world's adult population (11% of men and 15% of women) were obese. The global prevalence of obesity almost
tripled between 1975 and 2016. In this context, it is important to note that the continuous increase in life expectancy, the desire for a better quality of life, and the
high cost of medical care have led to a growing demand for functional foods in the market. People have started to realize that their food choices and their unhealthy
lifestyles have consequences for their health. An important role in this scenario is associated with functional foods containing probiotic strains, reported to benefit
human health. Here we report the development of natural yogurts based on native probiotic starter cultures of Enterococcus sp. strain BB3 (MK681869) and
Lactobacillus sp. strain BB6 (MK681868), isolated from raw cow milk of La Araucanía region of Chile. The odor and taste were the main parameters criticized by
the consumer, the analysis of CG-MS elucidated that the yogurt produced by the strain Enterococcus sp. strain BB3 (MK681869) produced a higher amount of heptan2-one, associated with a cheesy type odor, with less acceptance by the consumers. The acceptability of 6 types of yogurt was evaluated with a randomized analysis of
60 participants. The development of a functional dairy product based on probiotics is of interest because of its relation with positive changes in gut microbiota, and
at the same time with a possible decrease in body weight
