QUALITY ASSESSMENT, CHARACTERISTICS, PREFERENCE AND ACCEPTABILITY OF PROCESSED MEAT PRODUCTS; TSIRE (SUYA), KILICHI & BALANGU USING IKOLE EKITI, EKITI STATE, NIGERIA AS A CASE STUDY

 ABSTRACT

Reduction of protein malnutrition in many areas requires evaluation of simple, affordable, cheap but effective processing and preservation methods that ensure protein requirements are met. There is increase in the consumption of meat in the modern world. There is need to process raw meat to other forms to serve as alternatives to the consumers. The study is aimed at checking the acceptability of the processed meat product alternatives to boiled meat within the community.This paper is aimed at evaluating the consumption pattern of different meat products within a community and the levels of their preference and acceptability within the environment. Meat from ruminant cow is processed into different meat product suya, kilichi, balangu and was subjected to sensory evaluation to check which one the individuals within the community and why it is the most preferred. The study location is Ikole in Ikole local government in Ekiti state. The result showed that factors affecting meat purchase majorly were quality with about 21.5% of the population choosing the factor, then taste with about 19.75 and freshness with about 18.9%.The result also showed that factors determining the type of meat product purchased are taste and flavour with about 23.4%, affordability 20.7% and availability 15.3%.
