Embodiment 1
[0090] Example 1: Monitoring acidification of culture medium after thawing using a microwave device
[0091] Enzymes YF-L901 (composed of Streptococcus thermophilus and Lactobacillus bulgaricus), CHN-19, Flora Tradi 01 (composed of Lactococcus lactis subsp. Keto var. and Leuconostoc cremoris) and SSC-100 (Streptococcus thermophilus) are packaged in 5-liter sterile sachets, i.e. in the form of frozen granules stored at -40°C or -20°C 2.5kg of enzyme.
[0092] The pouch was placed in a microwave (Sairem, France) set at 600W.
[0093] Enzymes previously stored at -40°C were subjected to microwaves for 30 minutes to achieve complete thawing. Enzymes previously stored at -20°C require 25 minutes to completely thaw.
[0094] Place the pouch on the blender throughout the thawing process to ensure even thawing of the enzyme concentrate.
[0095] The test for medium acidification was performed on milk reconstituted from skim milk powder at 9.5% solids content heated at 99°C for 3...
Embodiment 2
[0101] Example 2: Monitoring Acidification of Medium After Thawing Using a Water Bath
[0102] Thaw multiple bacterial cultures using a water bath whose temperature is adjusted for each bacterium.
[0103] These bacteria are as follows:
[0104] - FMD-0046 containing a mixture of Lactococcus lactis subsp. lactis and Lactococcus lactis subsp. cremoris
[0105] - R604 containing a mixture of Lactococcus lactis subsp. lactis, Lactococcus lactis subsp. cremoris and Lactococcus lactis subsp. lactis diacetyl var.
[0106] - SSC-1 containing a mixture of Streptococcus thermophilus
[0107] - YF-L703 comprising a mixture of Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus.
[0108] For mesophilic enzymes such as FMD-0046 and R-604, the water bath temperature was 30°C for a thaw duration of 45 minutes. For thermophilic enzymes such as SSC-1 and YF-L703, the water bath temperature was 40°C for a thaw duration of 30 minutes.
[0109] Stir the fermentation...
