The OpenIT PS culture series effectively provides the typical distinctive mild sweetness to propionic cheeses, according to the company. In addition, there is a powerful gas release, allowing for perfect eye formation. The key properties of the new culture are said to be its capabilities of controlling and standardizing the fermentation process. The benefits are both a high and fast gas formation—and thus a short ripening time—and a well balanced sweet, nutty flavor with low pungency due to its low lipolytic activity. The PS-60 Direct Vat Set culture is available in frozen format in carton sizes fitted to the average vat sizes of the target dairies.
