Fermentation technology PPT, part 2 content: theme exploration

Explore theme one

Fermentation technology around you

1. Fermented foods (yoghurt, rice wine, vinegar, sauce...)

2. Biogas fermentation

yogurt

It is a milk product that uses fresh milk as raw material, is fermented by lactic acid bacteria, and then cooled and filled.

Yogurt not only retains all the advantages of milk, but also uses its strengths and avoids its weaknesses through processing in some aspects, making it a nutritional and health product more suitable for humans.

rice wine

There are two types of microorganisms in distiller's yeast: molds such as Rhizopus and Mucor and yeasts. Mold converts starch into sugar, which is the process of saccharification; yeast converts sugar into ethanol, which is the process of alcoholization.

Explore theme two

Industrial fermentation products

antibiotic

amino acids

sweetener

edible organic acids

Enzyme
