A comparative study of the use of radiation, lemon juice, and vinegar for the preparation and preservation of African giant snails (Achatina and Archachatina)

African giant snail is a popular alternative source of animal protein in Ghana and many other countries. The meat is high in lean protein and mineral elements. Ready-to-use meat obtained from snails can compete with animal proteins found on the market. After shelling, snails produced some slime that interfered with preparation and processing of the meat. This study aimed to provide consumers with ready-to-use fresh...
