In those that do contain micro-organisms, the nutrient supply will be severely limited by the size of the droplet. The crushed grain is then ground on large grinding stones to produce a dry flour.

The fresh tuber is peeled, washed and grated to produce pulp. When properly done, drying can preserve taste, concentrate flavors and protect nutritive values. Food processing/preparation methods help preserve the nutritional integrity of food products and enhance the bioavailability of dietary nutrients. Chilled rather than frozen meat had however already been successfully shipped the shorter distance from North America to Europe and by the end of the Century techniques had been refined to the extent that shipping chilled and frozen meat from North and South America and Australia to Europe was a large and profitable enterprise.

F0 values for UHT processes can be estimated from the holding temperature (T) and the residence time of the fastest moving stream of product, t. Initially UHT processing and aseptic packaging were confined to liquid products such as milk, fruit juices and some soups which would heat up very quickly due to convective heat transfer. Product is spread in a thin layer in the open (roadside, rooftop, packed earth etc.). Nevertheless to obtain commercial sterility it is given a bactericidal treatment, usually with hydrogen peroxide, sometimes coupled with UV irradiation. 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. Food added substances are added for specific purposes, regardless of whether to guarantee sanitation or to keep up food quality during the timeframe of realistic usability of an item. During drying a proportion of the microbial population will be killed and sub-lethally injured to an extent which depends on the drying technique and the temperature regime used. The expression handled food ordinarily alludes to food items produced through tertiary food preparing during new food industries. Peanuts are roasted by stirring in hot sand in a flat-bottom frying pot over a hot flame. Milling is an example of primary processing.

Polyvinylidene chloride, PVDC, is a material commonly used as a gas barrier; the oxygen permeability of a 25/m thick film is 10 cm3 m-2(24h)-1 atm-1 compared with values of 8500 and 1840 for low density and high density polythene respectively. Carried out by pounding in a mortar with pestle or grinding with stone. Its antimicrobial effect is a result of drying and the activity of wood smoke components such as phenols and formaldehyde which would probably not be allowed were they to be proposed as chemical preservatives in their own right. Using a blend quality prediction procedure based on the amino acid scores of mixtures of cereals and legumes, the relative performance of maize, millet and sorghum supplemented with cowpea, groundnut, pigeon pea, soybean and winged bean in various weaning formulations has been estimated. The pulp is then collected and packed in a hessian bag.

Food Microbiology, Food Preservation, Methods, Methods of Food Preservation. The capacity to preserve food is directly related to the level of technological development and the slow progress in upgrading traditional food processing and preservation techniques in West Africa contributes to food and nutrition insecurity in the sub-region.
