Abstract  Studies were conducted to investigate the effects of pH value, extraction time, extraction temperature, ratio of material to extraction medium and salt concentration on the solubility of yellow mealworm larvae protein, Tne results showed that pH value greatly influenced the solubility, minimum solubility was found at pH 5.8 and a maximum at pH 10 - 12. Salt ion could increase the solubility at the iso-electric point pH and slightly decreased the solubility at the pH value higher than that of the iso-electric point. Other factors did not significantly affect the solubility of the protein.

Key words： yellow mealworm      protein      solubility
