Technical design - As with any process Thermaflo are designing, we spend time to understand the client's needs and expectations then translate this into the technical design for their UHT milk plant. (UHT) processed milk powder (10² to 103 spores / g) and cheeses such as Cheddar (10² - 103 cfu/ g). The indirect system for an UHT milk production line typically comprises following types. When samples are tested organoleptically after this storage, the flavour shall be normal, and all signs of spoilage shall be absent. Many of these producers seek to improve the quality of milk products, for home consumption and especially for sale. 1. Greenfields Indonesia Malang. are highly regulated, thermal processes that revolve around sterilizing liquid products (typi- cally food) prior to packaging. Foods with subsequently cause spoilage in the processed milk [14]. The goal of the process is to sterilize foods and beverages like milk, juice, dressing and yogurt, while ensuring that they keep their sensory appeal and . The emetics syndrome is caused by the emetic toxin or cereulid, which is highly resistant to temperature (90 min at 126 °C) and highly stable (at least two months at 4° C), pH resistant (2 ≤ pH ≤ 11) and resistant to proteolytic enzymes.

Thus in UHT milk processing, very high temperatures for very short times (e.g., 140oC for 1-2 s) are favoured compared to a lower temperature longer time processes since it results in bacterial spore elimination with a lower loss of vitamins and better sensory quality. Some milk may not be appropriate for UHT, but may be appropriate for other uses. H. Burton. Bacteriology of the Heat Sterilization of Milk . Ira Nugerahani, M.Si.
