PROXIMATE ANALYSIS, MICROBIOLOGICAL ANALYSIS AND SENSORY EVALUATION OF GOOD MORNING OAT, POUNDO YAM, TOLLEX CUSTARD, PEAK MILK POWDER AND GINO TOMATO PASTE


ABSTRACT
The samples i.e. Good morning oat, Poundo yam, Tollex Custard, Peak milk powder and Gino Tomato paste were analyzed for crude protein, fat, moisture contents, crude fibre, ash content and carbohydrate content, Microbial analysis was done as well using Eosin methylene blue agar and Nutrient agar. The sensory evaluation of the samples were also carried out. The result of the proximate analysis of these samples showed that they contain essential nutrients needed by the body for normal growth. The high moisture content in Gino tomato paste (61.10%) is an indication that the product cannot be stored for a long period of time. The result of microbial analysis revealed that Gino tomato paste has the highest microbial viable count of 5.2 x 103cfu/gm and 5.8 x103cfu/gm on the media used after incubation. Sensory evaluation result showed that the samples was acceptable with respect to colour, taste and appearance.

CHAPTER ONE
INTRODUCTION
            Food is any substance or materials eaten or drink to provide nutritional support for the body or for pleasure. It usually consist of plant and animal origin, that contains essential nutrients such as carbohydrate, fats, protein, vitamins or mineral and is ingested and assimilated by an organism to produce energy, stimulate growth and maintain life. Historically, people obtained food from hunting, farming known as Agriculture – Today most of the food energy consumed by the world population is supplied by the food industry operated by multinational cooperation using industrial agricultural method (Aguilera, et al., 1999)
