Elemental analysis of mango ripened by different postharvest treatments using laser induced breakdown spectroscopic

Laser induced breakdown spectroscopy (LIBS) provides sample information on elemental scale. Current result depicts both qualitative and quantitative detection of most prominent organic elements like hydrogen (H), nitrogen (N), oxygen (O) and carbon (C) from mango pulp ripened under different post- harvest treatments. Similarly, it also indicates variable concentration of minerals such as calcium (Ca), magnesium (Mg) and potassium (K) under these treatments. The concentration of Ca, Mg and K detected under different postharvest ripening techniques are 0.163−0.257 mg\100 gm, 0.212−0.431 mg\100 gm and 0.675−1.802 mg\100 gm respectively. Moreover, the respective concentration H, N, O and C are 41.56−46.51 gm/100 gm, 41.28−44.91 gm\100 gm, 12.11−14.49 gm\100 gm and 53.1−100.1 mg\100 gm. Traces of arsenic (As) or phosphorous (P) were not found in samples treated with calcium carbide. Further studies on commercial grade fruits ripened with these agents are required to differentiate among nutritional elements of mango fruits treated under different ripening agents as well as to confirm the presence/absence of health hazardous elements.
