Substrate composition effect on the nutritional quality of Pleurotus ostreatus (MK751847) fruiting body

Summary

Researchers studied how different growing materials affect the nutritional value of oyster mushrooms. They found that mushrooms grown on palm oil waste mixed with wheat or rice bran had better nutritional quality than those grown on single materials. The best mushrooms for protein came from materials containing wheat bran, while fermented materials produced the most vitamins. This research shows how agricultural waste can be recycled into nutritious food.

Background

Malnutrition and protein shortage remain serious concerns in developing countries. Mushroom cultivation offers a promising alternative for improving food production with high protein and nutritional content to meet growing population demands.

Objective

To evaluate the effect of different substrate compositions supplemented with wheat bran and rice bran on the nutritional and medicinal properties of Pleurotus ostreatus fruiting bodies cultivated on palm oil waste materials.

Results

Shaft supplemented with wheat bran produced highest protein content (19.14%), bunch alone gave highest fat (1.70%), and fermented bunch produced highest vitamins A, E, and D. Supplemented substrates produced mushrooms with better nutritional values than non-supplemented substrates, with wheat and rice bran supplements showing superior results.

Conclusion

Palm oil bunch and shaft supplemented with wheat bran and rice bran are ideal substrates for cultivating P. ostreatus with enhanced nutritional quality. Substrate composition significantly impacts the nutritional profile of mushrooms, and agricultural waste can be effectively diverted into mushroom production for economic and nutritional benefits.
