Mango Waste Case Study

Introduction
Mango, Mangifera indica belong to the family Anacardiaceae. It is one of the choicest fruit crops of tropical and sub-tropical regions. Mango is a very popular fruit, it is often referred to as ‘king of fruits’ in the tropical world (Singh et al. 2002), but after consumed or used by the mango processing industry, mango seeds are generally only disposed of as waste (Puravankara et al. 2000; Kittiphoom 2012). On the other hand, enough scientific information is available regarding the nutritional importance of mango waste. From environmental and food insecurity perspectives, it is extremely important to efficiently utilize of mango waste, for safer environment and feeding of ever increasing human population. The issue of food insecurity in Asia and Africa in the coming 35-50 years may lead to hunger and starvation (FAO 2006).
Mango seed account for 35%-55% of the fruit, depending on the variety (Bhalerao et al. 1989), and 75% of the stone (Ahmed et al. 2007). The kernel inside the seed represents from 45% to 75% of
MSKO was included in protein based diet at 10 and 20% concentrations, compared with a control group that was fed on groundnut oil. Feed efficiency-ratio, digestibility and growth performance of rats fed on MSKO were not significantly different from the control group. Toxicological studies evidenced no difference in reproductive performance, serum, liver, total cholesterol, total lipids, triglycerides and organ weight from the control. Histopathological evaluation of organs did not reveal any abnormality. These results suggested that MSKO no toxic effects (Rukmini & Vijayaraghavan 1984). Analysis of cholesterol content in MSKO showed that it is cholesterol free (Mostafa 2013). Previous, study in livestock feeds by Agunbiade & Olanlokun (2006) showed that MSK is not toxic and can be safely introduced as a supplement into livestock
