Product, dried shelf life determinants

According to current PDA guidelines, an acceptable pharmaceutical product should exhibit less than 10% deterioration after 2 years.5 Protein biopharmaceuticals usually have to be stored under refrigerated conditions or freeze dried to achieve an acceptable shelf life. EL IS As for aggregates and product variants as discussed previously would be applicable for determining shelf life. 

Each step in the processing and packaging of dry milk products can influence the properties of the finished product. The total heat treatment (i.e., time x temperature) for each step during the manufacture of milk powder is important in determining its properties. The method of heating and the total heat exposure influence protein denaturation, oxidation of the fat and the subsequent shelf-life of the powder. 

Frying is defined as a process of cooking and drying through contact with hot oil. It is intended to make food more palatable and tasteful, but at the same time makes food safer and provides a preservative effect that results from thermal destruction of microorganisms and enzymes, and a reduction in water activity at the surface or throughout the food. The shelf life of fried products is mostly determined by the moisture content after frying. Products that retain a moist...
