PRODUCTION OF ASSORTED SNACKS FROM COMPOSITE FLOUR WITH SPECIAL REFERENCES TO SWEET POTATO

ABSTRACT

This research was carried out to know the usefulness of our local root and tuber crops as composite flour in bakery industry.

Also, to put the readers mind off on the use of imported wheat flour and allow varied menu in Nigeria diet. It is also to minimize government expenditure and eradicate difficulties in importing wheat flour.

1. INTRODUCTION

DEFINITION

Flour can be defined as white powder-like substance made from tuber crops e.g. sweet potatoes, cassava, yam and cocoyam. Among tuber crops, potato is by far the most efficient tuber crops in Nigeria in terms of tuber yield and days to mature. It matures in about 80-90 days as compared to 9-12 months respectively.

Okonkwo, et al, 1984 states that tubers yield 15-30 tones under Nigeria condition. Because of the short maturity period, two or more consequences planting of potato is possible in a year making. It is the highest yielding tuber crop in the country. The total production in 2007 was estimated at 800, 000 tones and at the present price of N12, 000 per tone; this is equivalent to foreign exchange saving about N3.5 billion in the country. However, because of increase in population growth and economic depression of the country, the government now comes up with SAP (structural Adjustment Programme) staling that Nigeria will henceforth maximize the utilization of foreign resources and raw materials so that importation of foreign food and items will be reduced to the nearest minimize.

Because of this, the importation of wheat has been reduced, which could not meet the demand of people. So in order to solve this problem, we now look at possibility of doing much research on the use of locally available tuber crops, such as sweet potato on the production of bakery products, they may serve the same purpose as wheat flour.

This project is therefore aimed at throwing light into composite flour as close substitute of wheat flour.

These flour mixtures are referred to as composite flour whether or not they contain wheat flour

These are usually two major types of composite flour.

1. Mixture of wheat flour with local crop flour: the purpose is to substitute wheat flour with local crop flour to increase the nutritive value of the wheat flour.
2. Pure mixture of potato flour: This is to known how good potato is in baking and in snacks.
   1. BACKGROUND INFORMATION

About 85% of the potato grown in Nigeria comes from Jos Plateau. The dry season production constitutes about 30% of the total production and the dry season crop is grown by those who have facilities for irrigation (Ene et al 2007). Potato is grown in both rainy and dry season. In Jos Plateau (14000m), Manbilla (18000m) and Bill (800m) Plateau.

Most Northern states such as Kano, Kaduna, Borno, Kwara, Yobe, Sokoto, Taraba Adamawa and Bauchi also grows potato during the harmattan months (November to February) when temperature is sufficiently low for potato production.

Introducing local tuber such as potatoes as substitute of wheat flour is the main objectives of this research work.
