This paper evaluates the effects of microwave heating (450 W for 2, 4, 6, and 8 min) on compositional characteristics of underutilized and undervalued plum kernels. Compared to the raw sample, microwave-treated samples showed a significant improvement in oil content (4.03%), crude fiber (3.62%), total ash (3.01%), and carbohydrates content (14.92%) at 450W for 6 min. On the contrary, a statistically significant (p < 0.05) decrease of 7.61% was observed in crude protein values at the same processing conditions. Microwave heating at 540 W for 6 min showed a considerable reduction of 37.81% in cyanogenic glycosides of plum kernel samples, while the prolonged heating (450 W for 8 min) showed damaging effect (burning spots) on the quality characteristics. The overall findings suggest that the optimum degree and duration of microwave heating from the standpoint of nutritional levels and degradation of cyanogenic glycosides was 450 W for 6 minutes. This novel technological strategy can potentially expand the usage of plum kernels in various diversified food preparations.
