High-Snf and/or Low-Fat Fermented Milk Excellent in Savor and Process for Production Thereof
The invention aims at broadly dividing the deteriorations in the savor and palatability of low-fat and high-SNF (solids-not-fat) food produced by adding skim milk powder to low-fat fermented milk into (a) one due to lowered milk fat content and (b) one due to the addition of skim milk powder in a high concentration and inhibiting each deterioration without any additive by a more natural method to improve the savor and palatability. The invention relates to a process for the production of fermented milk having an SNF content of 11% by weight or above and/or a milk fat content of 0.1 to 2.0% by weight which comprises adjusting the dissolved oxygen content of a raw material mixture for fermented milk at the initiation of fermentation to 5 ppm or below, adding a starter to the raw material mixture, and conducting the fermentation of the obtained mixture at 30 to 46° C.; and fermented milk produced by the process.
1 . A process for producing fermented milk with a milk solids-not-fat (SNF) content of 11 wt % or more and/or a milk fat content of 0.1 wt %-2.0 wt %, comprising
adjusting dissolved oxygen concentration in a fermented-milk material mixture to 5 ppm or less at the start of the fermentation;
adding an amount of a starter to the fermented-milk material mixture; and
fermenting the fermented-milk material mixture at a fermentation temperature between 30° C.-46° C., inclusive.
2 . The process according to claim 1 , wherein the fermentation temperature is between 30° C.-40° C., inclusive.
3 . The process according to claim 1 , wherein the amount of the starter added to the fermented-milk material mixture is 50%-25% of a standard amount of addition.
4 . The process according to claim 3 , wherein the fermentation temperature is between 38° C.-46° C., inclusive.
5 . Fermented milk with a SNF content of 11 wt % or more and/or a milk fat content of 0.1 wt %-2.0 wt % produced by the process according to any one of claims 1 to 4 .
6 . The fermented milk according to claim 5 , characterized in that it has milk fat taste with a level similar to that of fermented milk produced by a standard process having a milk fat content at least 1 wt % higher than that of the fermented milk according to claim 5 , without addition of a milk-fat alternative or a milk-flavoring agent.
