MICROBIOLOGICAL ANALYSIS OF DRY CASSAVA PEEL USED IN THE PREPARATION OF PIG FEEDS

MICROBIOLOGICAL ANALYSIS OF DRY CASSAVA PEEL USED IN THE PREPARATION OF PIG FEEDS

CHAPITRE ONE

1.0 General Introduction

Manihot esculenta, sometimes known as ”cassava,” is a woody shrub of the Euphorbiaceae spurge family native to South America. It is widely grown as an annual crop in tropical and subtropical areas for its edible starchy tuberous root, which is a good source of carbohydrates. Cassava is further divided into species such as M. aesculifolia (AES), M. Brachyloba (BLO), M. Carthaginensis (CTH), M. Esulenta subsp. Tristis (TST). However, it includes cynogens (1.3%) depending on cultivar (Stupak et al., 2006) and a high concentration of cyanogenic glucosiders in cassava flour (Cumbane et al., 2007), which may limit cassava root consumption and livestock feeding. Cassava thought to have originated in Brazil and Paraguay, but it spread throughout tropical South and Central America long before Columbus arrived. Cassava is now one of the world’s most important food crops in many countries.

Despite being poorly known or used in Western countries, it is the world’s sixth most important food crop. Cassava tubers, or ”Yuca,” as the plant is known in South America, are exceptionally high in starch; in fact, it is one of the richest sources of starch of any food plant (it contains up to ten times as much as corn and twice as much as potatoes). The starch content of big tubers, which can weigh up to 5kg, is 30% of their dry weight. However, due to the presence of linamarin, a precursor of cyanode glycosides, the entire plant is hazardous if taken uncooked. Nigeria is the world’s largest cassava producer, whereas Thailand is the world’s top dried cassava exporter.

1.1 The Study’s Objective

The study’s goals are as follows:

To count the microbiological content of dried cassava peel, as well as to isolate and identify the probable spoiling organism of this product.

To give recommendations on how to preserve the peels before they are consumed by livestock.

1.2 Scope And Restriction

The limitations of this study were the inadequacy of current literature tone and funding constraints.
