摘要:

The flavour and nutritional quality of UHT processed milk is discussed and suggestions are made for ways of minimizing undesirable changes during heat treatment. UHT treatment of milk using an infusion heater is described, and it is concluded that whole milk processed in this way is a typical directly heated UHT milk.

摘要:

Different industries set different standards for their aseptic operations. A standard for low acid foods k suggested. Cans and glass containers are discussed and some alternatives are mentioned. The suitability of plastics and plastics laminates for aseptic packaging k highlighted. The efficacy of the form‐filled‐seal technique k compared to that of the preformed system for aseptic operations. The main features of equipment for aseptic packaging in bulk are mentioned. Some possible future developments are predicted and novel applications for large bulk packs are suggested. Bulk aseptic packaging is in its in fancy and the current high cost of bulk packs may, in the short term, restrict their application to specialist dut

摘要:

The development of plastics materials is traced through their use as simple replacements for other packaging materials to their increasing sophistication in specialist applications. The development of improved barriers and conversion processes has increasing opened new areas of penetration for plastics in food packaging. The role of plastics in aseptics together with conversion processes commonly used is discussed, and it is considered that as filling technology develops, plastics materials will be available to package the products.

摘要:

The paper shows the possible influences of environmental factors and legislation on the dairy industry, particularly in relation to UHT processing dairies. Problems of air, noise and odour pollution, effluent disposal, and the disposal of solids wastes are considered. Pressure to reduce the effects of these consequences of processing is likely to continue.

摘要:

The addition of commercial lipolytic enzymes to experimental Cheddar cheese accelerated the liberation of free fatty acids during ripening. The substrate specificity of the added enzymes generally governed the chain lengths of the free fatty acids in the cheeses. None of the enzymes accelerated the formation of typical flavour in either the presence or the absence of a flavour‐enhancing proteinase, but higher addition levels produced lipolytic rancidit

摘要:

The preparation and properties of sterile concentrates, based on milk concentrated by ultrafiltration with added carbohydrate, are discussed. Methods are given for optimization of initial heat stability and shelf life. The new products are sweet but suffer from no apparent technical obstructions to their commercial exploitation.
