ABSTRACT
This project was aimed at investigating the effect of drying on Vitamin C content of moringa powder and to also determine the amount of vitamin C in both fresh and powdered moringa leaves. The unit operation included washing, weighing, drying, milling, sorting and cleaning. The fresh and dried products were subjected to Vitamin C analysis, the analysis was done to obtain the initial and final reading, two different analysis was carried out.

The result of the analysis showed that the dried products contains a higher Vitamin C value than fresh products in all the days of the analysis. 210Mg/100ml in dried product while 90mg/100ml in fresh products.
CHAPTER ONE
Introduction
Moringa oleifera belongs to the family moringaleae which is a single genus family of shrubs and trees cultivated across the whole of the tropical belt and used for a variety of purposes (Jahn, 1986). The dry seed suspension is known to be natural coagulant and coagulant aid (Folkard, et al., 1989).
In the Sudan, dry moringa oleifera seed are used in place of alum by women to treat highly turbid Nile water. In Northern Nigeria, the fresh leaves are used as a vegetable, roots for medicinal purposes and branches for demarcation of property boundaries and fencing. Studies by (Eilert et al., 1981) identified the presence of an active antimicrobial agent in moringa oleifera seeds.
The active agent isolated was found to be 4a L-rhamnosyloxy-benzyl isolhiocyanate at present the only known glycosidic mustard oil (Madsen et al., 18987) carried out coagulation and bacterial reduction studies on turbid Nile water in the Sudan using moringa oleifera seeds and observed turbidity reduction of 80 – 99.5% paralleled by a bacterial reduction of 1 – 4 u log units (90 – 99.9%) within the first one to two hours of treatment, the bacteria being concentrated in the coagulated sediment.
Sani, (1990) carried out jar tests with moringa oleiifera as the primary coagulant using water from different sources (vix two surface and two shallow wells) with turbidities from 100 to 800 ntu and 80 to 150ntu respectively and hardness from 180 to 300mg/as CaCo3.
It was observed that in addition to turbidity reduction of 92 – 99% the hardness was also reduced to between 60 – 70% after coagulation and two hours setting. The softening property of moringa oleifera which was accidentally discovered in that study is the only one documented to date. The present study was therefore carried out to explore further the potential of this multipurpose tropical plant as a new method for use in the softening of hard ground water.
Each tree can produce approximately 15000 – 25000 seeds and 400 – 1000pod/year. The average of weight of non shelled ced is 0.3gm (300mg). The kernel to hull ratio is 75.25% (Jahn, 1988). About 75% of the presence world population lives in the developing countries of the world.
About 1.2 billion people still lack safe drinking water and more than 6 million children die from diarrhea in developing countries every year. However, it is untenable and unbelievable under all situations that water borne diseases still kill on the average 25,000 people every day in developing countries while millions suffer the debilitating effects of these diseases (Gassenschmidt, et al., 1995; Kalbamatten, et al.,. 1983)
Safe drinking water is essential to the health and welfare of a community, and water from all sources must have some form of purification before consumption. Various methods are used to make water safe and attractive to the consumer. The method employed depends on the character of the raw water. One of the problems with treatment of surface water is the large seasonal variation in turbidity (McConnachie et al., 1999).
Moringa oleifera is one of the most wide spread plant species that grows quickly at low altitudes in the whole tropical belt, ioncluding arid zones. It can grow on medium soils having relatively low humidity (Ndabigengesere et al., 1998). Moringa oleifera seeds are an organic natural polymer. Anhwange Frose (2004) moringa the tree of life.
Nutritive value of moringa oleifera, Retrieved 13 August 2006. He has presented moringa oleifera as a coagulant after her studies in the Sudan when she noticed that Sudanese village women used it at home to clear the turbid Nile water. Later, many researchers have reported on the various uses of moringa oleifera seeds as coagulant and coagulant aid in the last 20 years.
Moringa oleifera coagulant has been found to have high coagulation activity only for high turbidity water. The activity is low for low turbid water. Therefore, it is important to improve this characteristics of this plant by identifying its bioactive constituents, which has high coagulation activity. This is one of the objectives of the study.
