Substrate Composition Effect on the Nutritional Quality of Pleurotus ostreatus (MK751847) Fruiting Body

Summary

This research shows how agricultural waste products like palm oil residues can be used to grow nutritious mushrooms. The study found that adding supplements like wheat bran and rice bran to palm oil waste produces mushrooms with enhanced protein and vitamin content. This has important implications for addressing food security and nutrition challenges. Impacts on everyday life: – Provides a sustainable way to convert agricultural waste into nutritious food – Offers an affordable protein source to help combat malnutrition – Creates economic opportunities through mushroom cultivation – Reduces environmental waste by recycling palm oil byproducts – Demonstrates how to optimize mushroom nutrition through growing conditions

Background

Cases of malnutrition and protein shortages have become serious concerns in many developing countries including Nigeria. Food insecurity remains one of the greatest global challenges with growing world population, especially in under-developed countries. This necessitates finding alternative ways to improve food production with high protein and nutritional content to meet increasing population demands. Mushroom cultivation and production offers a promising alternative to meet growing global protein demands and combat malnutrition.

Objective

This study aimed to evaluate the effect of different substrate compositions with supplements on the nutritional and medicinal properties of Pleurotus ostreatus (MK751847) fruiting body. The research examined how underutilized palm oil waste (shaft and bunch) and sawdust supplemented with wheat and rice bran affected the nutritional quality of cultivated mushrooms.

Results

The highest protein content (19.14%) was found in shaft supplemented with wheat bran, while the highest fat content (1.70%) was in bunch alone. Ash content was highest (10.10%) in fermented bunch. Bunch combined with sawdust gave the highest carbohydrate content (6.19%). Fermented bunch produced mushrooms with the highest vitamin A (2.21 UI/100g), vitamin E (5.71 UI/100g), and vitamin D (5.90 UI/100g) levels. Overall, substrates supplemented with wheat bran and rice bran produced mushrooms with better nutritional profiles compared to non-supplemented substrates.

Conclusion

Palm oil bunch and shaft supplemented with wheat bran and rice bran are ideal substrates for growing P. ostreatus, with substrate variations significantly impacting the nutritional composition. Substrate supplementation with wheat bran and rice bran produced mushrooms with enhanced nutritional value, particularly protein content. The findings demonstrate that substrate composition can be modified to achieve desired mushroom nutrient profiles for optimal nutrition.
