Impact of Cooking Methods on Sensory Evaluation and Nutritional Properties of Caterpillar Medicinal Mushroom Cordyceps militaris (Ascomycetes).

This study addresses the alterations in nutrients [calcium, iron, and vitamins C and E (VC and VE, respectively)] and cordycepin content, alongside its sensory appeal in Cordyceps militaris, subjected to five distinct cooking methods: boiling, steaming, roasting, microwaving, and deep-frying. A comparative analysis showed the notable decline in nutrient content across most cooking methods excluding deep-frying. In notable contrast, the content of VE was substantially amplified during deep-frying, thereby emphasizing its value in preserving nutrients. However, an exception was noted wherein VE content remained essentially unchanged in the microwaved samples. Notably, the cordycepin content in boiled C. militaris reduced significantly, contrastingly, an elevation in this content was recorded for steamed, microwaved, or deep-fried samples, with roasting producing a stable content comparable to raw samples. The principal component analysis further discerned the iron, VC, and cordycepin as primary influencers on raw and roasted C. militaris, signifying superior retention during roasting, whereas deep-fried samples were predominantly affected by the calcium and VE content. Observation on nutrient losses revealed that boiling, steaming, and microwaving were less efficacious, compared with roasting and deep-frying. Sensory evaluations inductively favored steaming as synonymous with the finest culinary attribute, whereas deep-frying ranked least favorably on the sensory scale. Consequently, the present study offers refined dietary advice for the consumption of C. militaris catered to specific demographic groups, deepening understanding of the effects of various culinary practices on its overall nutrient profile and organoleptic properties.
