(With over 12 years of professional experience in the agricultural industry) Food research explains the basics of food processing techniques in food processing industries. Carbon dioxide is included for its inhibitory effect, nitrogen is non-inhibitory but has low water solubility and can therefore prevent pack collapse when ,high concentrations of CO2 are used. Although skim milk is often included in the formulation, it is possible to make the aqueous phase in margarine even more deficient nutritionally than in butter, thus increasing the microbiological stability further. Nature provided early humans with an object lesson in the preservative value of high solute concentrations in the form of honey produced by bees from the nectar of plants. SECONDARY PROCESSING. Thank you so much for sharing! It is also lowered by the addition of solutes such as salt and sugar. The composition of the gas atmosphere changes during storage as a result of product and microbial respiration, dissolution of CO2 into the aqueous phase, and the different rates of gas exchange across the packing membrane. Where pasteurization is introduced to improve safety, its effect can be doubly beneficial. This means that they are less temperature sensitive so that higher temperatures will increase the microbial death rate more than they increase the loss of food quality associated with thermal reactions. Soaked cereal grains may also be ground into meals which are mixed with water to form dough whole cereal meals produced by grinding are not passed through a sieve to remove any part of the cereal. Butter spoilage is most often due to the development of chemical rancidity but microbiological problems do also occur in the form of cheesy, putrid or fruity odours or the rancid flavour of butyric acid produced by butterfat hydrolysis. These were based on the cooling produced by the vaporization of refrigerant liquids, originally ether but later liquid ammonia. Content Guidelines 2. Apart from their poor nutritional qualities, traditional African cereal-based gruels used as complementary foods have high hot paste viscosity and require considerable dilution before feeding; a factor that further reduces energy and nutrient density.
