$\small\mathbf\orange{{yeast }}$

Yeasts are eukaryotic, single-celled microorganisms classified as members of the fungus kingdom. The first yeast originated hundreds of millions of years ago, and at least 1,500 species are currently recognized. They are estimated to constitute 1% of all described fungal species.

$\small\mathbf\red{{ role \: in \: food \: preservation}}$

Yeasts play essential role due to their important functions in dairy based products such as contributing to the ripening of cheese, speeding up the maturation, improving texture and aroma characteristics of certain milk products, increasing pH of cheese, manufacturing of some metabolites like ethanol, acetaldehyde, CO2.

$\small\mathbf\purple{{role \: of \: yeast \: in \: food \: spoilage }}$

Spoilage is a consequence of yeast growth in the product. Food components are utilized as growth substrates by the yeasts and are transformed into a vast array of metabolic end products. In this way, the chemical, physical, and sensory properties of the food are changed.
