Comparative analysis of nutrients in fruiting bodies between wild and cultivated Morchella in different cultivation models

Abstract

Objective: This study aimed to estimate the nutritive value of wild and cultivated Morchella in Northern Shaanxi. Methods: Morchella fruiting bodies wildly growing in Northern Shaanxi and cultivated in three models (greenhouse, plastic shed and understory) were used to analyze the difference in the main nutrition components. Results: In terms of crude protein, crude fat, crude fiber and water content, all cultivated Morchella were slightly higher than those in the wild. Moreover, the amino acid content of cultivated Morchella was also higher and the amino acid ratio of understory was the most reasonable. Both the wild and the cultivated were rich in unsaturated fatty acids, and the content of unsaturated fatty acids was significantly higher than that of saturated fatty acids. Unsaturated fatty acids were mainly oleic acid and linoleic acid. Both the wild and the cultivated were rich in mineral elements, but the content of mineral elements in the wild Morchella was more abundant. Conclusion: The nutritional value of the cultivated Morchella was not lower than that of the wild Morchella in Northern Shaanxi, but had slightly difference due to cultivation models.
