Description |
Pesticide is any substance or mixture of substances intended for preventing, destroying, repelling or mitigating any pest. It is also used as substances applied to crops either before or after harvest to protect the commodity from deterioration during storage and transport (FAO, 2002). Increased realization in the recent years regarding the presence of harmful pesticide residues in the food consumed had a negative impact on an individual’s health. Food safety is an area which has concern on the account of food on human health. Therefore, the present study was undertaken to assess the pesticide residue of the selected whole and processed food grains grown in Southern zone of Andhrapradesh. The selected samples rice, redgram, blackgram and bengalgram were collected randomly from the farmers of 3 districts (Chittoor, Nellore and Kadapa) and homogenised. The study had two aspects as field work and lab analysis. Field work included the procurement of samples from the farmers and to know the awareness of the farmers regarding the pesticide package of practices. The lab work included the analysis of nutritional quality and pesticide residue content. The nutritional quality of the selected samples included moisture, fat, protein, ash, fibre and carbohydrate analysis according to AOAC 1981, 1990 and 2005 methods. The pesticide residue content included monochrotophos, chloripyriphos, quinalphos, endosulphan, carbofuran and acephate by multiresidue analysis method (1983). The values of the proximates i.e., moisture, protein, fat, fibre, ash and carbohydrates were tabulated and the results obtained showed that there exists significant difference between whole and processed food grains with respect to all the 6 parameters of the four selected crops except for protein of blackgram, fibre and fat of rice, ash and carbohydrate of redgram and bengalgram. The pesticide residual content of the selected whole and processed grains showed that average percent recoveries at the spiking levels were not detected (BDL) for any of the pesticides in all the samples. As the samples selected had enough safety limiting period the pesticide metabolites were degraded. Prolonged storage and exposure to pre-processing techniques also contributed for the declinement of pesticide residues. So, the pesticide residues of samples were declined. Therefore, cereals and pulses are safe for consumption. |
