Mango Rainforest In Thailand

1.1 Background

Since the fruits export is increasing, mango is the most fruit cultivated areas in Thailand. The production areas increased steadily from 2,019,980 in 2011 to 2,046,280 acres in 2012 and 2,087,680 acres in 2013 respectively (Office of agricultural economics. Ministry of agriculture and cooperatives, 2013). 90% of mango production is consumed in the country and used only parts of mango pulp in consumption and another mango processed. Another parts of mango such as peels and seeds about 40-60% becomes the waste without utilization. The wastes ratio is peels 12-15%, fraction of mango flesh 5-10% and mango seeds 15-20%. These resulted in tremendous wastes in agriculture and lead to the environmental problems (Inthaprakon, 2009).

In addition, many studies indicated that antioxidant can be reduced risks of many diseases. Normally, the body can eliminate free radicals before the harm is done but if there created free radicals faster more than exceeded to eliminated from the body in timely, free radicals will damage cells and tissues which affected the health (Songjitsomboon, 2007). Therefore, the study of the extracts of agricultural residues, in this place is mango seed kernels to increase wastes value and generate income for the villagers, especially can reduce agricultural wastes arising from the mango seed.

In the present, antioxidant compounds are commonly used as a supplement. The most widely known was the grape seed extracts that quite expensive. The compounds in grape seeds extract were rich in various kinds of phenolic compounds as reported that the phenolic compounds can inhibit several activities such as anti-oxidation, inhibit inflammation, inhibit cancer, anti-microbial and so on (Lee, 2004; Evans, 1997). The comparison of quantity and quality of grape seed and mango seed kernel extracts indicate that how difference they are, for the useful to be interchangeably applied in the
