| | Production of sterile yoghurt - Patent 4235934 |
 | | However, irrespective of whether or how the yoghurt product is adjusted for aesthetic improvement, the outstanding shelf stability and sterility of the yoghurt product of the present invention is achieved only by appropriate modification of the milk prior to culturing and by adherence to the essential processing steps and parameters described herein. |
 | | The shelf stable, sterilized yoghurt of the present invention may be prepared from milk having a fat content ranging anywhere between full cream and skim with or without added dry milk products, although generally full cream and milk standardized to a content of 3.5% fat by weight is used. |
 | | The sterilized yoghurt product should be cooled to increase its firmness and, to that end, the sterilized containers may be refrigerated at about 4°-6° C. for at least 24 hours or for as many as a few days, e.g., 2 to 4 days, depending upon just how firm a product is desired. |
