Cultivars Effect on the Physical Characteristics of Pumpkin (Cucurbita moschata Duch.) Seeds and Kernels
This study aimed to evaluate the physical properties of pumpkin seeds and kernels of five different cultivars, namely Pusa Vishwas (PV), Narendra Upkar (NU), Narendra Agrim (NA), Kashi Harit (KH) and Azad pumpkin 1 (AP1), commonly grown in subtropical regions of India. The dimensions of seeds and kernels were determined by image processing setup, and their frequency distribution curve showed normal distribution pattern for all cultivars. Seeds of KH cultivar scored maximum values for width, thickness, geometric mean diameter, sphericity, volume and surface area, whereas maximum length and arithmetic mean diameter were found in the seeds of NA cultivar. NU cultivar showed the highest bulk density for both seeds and kernels, and therefore less space is required for its storage. Seeds of all the cultivars scored higher values for 1000 seed mass (M1000) and hardness than their kernels. Seeds and kernels of KH cultivar showed the least value of porosity and angle of repose, which indicates shallow bins are suitable for their storage. Coefficient of static friction of kernels was lesser than its seeds in all the tested surfaces with aluminum showing the maximum and fiberglass showing the least resistance. It indicates that kernel can be easily passed in hoppers and other loading and unloading devices. Principal component analysis revealed that length, width and M1000 were the major parameters that affect the physical properties of pumpkin seeds. Results of this study provide rudimental knowledge essential for designing storage and processing machines for conversion of seeds and kernels into their value-added products.
