The present study aims to investigate the nutritional profile of non-mulberry silk worm Philosamia ricini, an edible insect consumed in Assam, India. This research focuses on exploring the proximate composition, mineral and trace element contents. Both the larval and pupal stages were studied. The moisture, crude protein, fat, fibre, total ash and carbohydrates/ Nitrogen Free Extract were determined using standard methods of AOAC while minerals and trace elements were analysed using ICP-OES. Crude protein and crude fat were found to be higher in larval and pupal stages, respectively. Both the larval and pupal stages showed high levels of potassium (K). Findings reveal that P. ricini is highly nutritious, with significant levels of crude protein and crude fat. The silkworm also contains considerable amounts of key minerals such as calcium, iron and magnesium, as well as trace elements like zinc and copper. These results highlight the potential of P. ricini as a sustainable and nutrient-rich food source.
