SMALL - SCALE MEAT MEAL MANUFACTURE

• It is rarely possible to make immediate use of boiled offal or condemned material.
• The direct conversion of raw, uncooked material into meat meal by sun drying often attempted in very dry countries, is inadvisable because of the risk of spreading disease.
• Such raw meat meal, is virtually impossible to mill since, the dried material contains a substantial amount of fat, which will cause rancidity.
• Hence, the small, home production of meat meal may be, (it must) comply with three general principles viz.
• Sterilizing and making the product safe for use as stock feed.
• Reducing the moisture to a minimum creates a condition unfavourable for bacterial growth and therefore, prevents decomposition and economizing on transport.
• Recovering the fat from the sterilized and dried meal, this would otherwise cause rancidity.
• The above-mentioned requirements can be met by simple methods using simple equipments.
• If carefully prepared, the final products should have a low fat and moisture content a high protein percentage good keeping qualities and a pleasant odour.
• The steps in production are
  • Boiling
  • Draining
  • Pressing
  • Drying and
  • Milling
