The milk of goats and sheep is similar in composition to that of cows. 2. Milk protein consists mainly of casein, and it exists in several classes: α, β, etc. If milk pH falls below 4.6, the casein precipitates. Although casein represents 80–85% of total milk protein, when precipitation occurs, the liquid portion is referred to as whey. 3.

    Premature spoilage and varying product quality due to microbial contamination still constitute major problems in the production of microfiltered and pasteurized extended shelf life (ESL) milk. Spoilage-associated bacteria may enter the product either as part of the raw milk microbiota or as recontaminants in the dairy plant.

    Pasteurized milk usually is spoiled by psychrotolerant bacteria, typically nonsporeforming Gram-negative rods or Gram-positive sporeforming bacteria. Spoilage of pasteurized milk by Gram-negative rods, such as Pseudomonas spp., often involves inadequate heating of milk or more frequently, postprocessing contamination.

    The process of heating wine for preservation purposes has been known in China since AD 1117, and was documented in Japan in the diary Tamonin-nikki, written by a series of monks between 1478 and 1618. Much later, in 1768, research performed by Italian priest and scientist Lazzaro Spallanzaniproved a product could be made "sterile" after thermal processing. Spallanzani boiled meat broth for one hour, sealed the container immediately after boiling, and noticed that the broth did not spoil and was free fro
