fermentation test

fermentation test

An obsolete term for a crude test that distinguishes glucose from other reducing sugars by virtue of the fact that glucose can serve as a substrate for yeast fermentation, while other reducing sugars (e.g., lactose, galactose) do not.

Carbonhydrate fermentation tests were carried out with the Analytical Profile Index (API 50 CH) strips (bioMerieux, Tokyo, Japan) of 49 different compounds and one control, according to the manufacturer's instructions, and reactions were determined after incubation at 30AdegC for 48 h (Lopez-Diaz et al.
The juices stored at 0, 8, 24 and 48 hours at 30[degrees]C were considered for the fermentation tests, which were carried out in sterilized 250mL Erlenmeyer flasks with 100mL of final juice volume, in duplicate, 8-10% w/v of commercial baking yeast, at 30[degrees]C, without shaking.
