Currently around one billion people in the world do not have access to a diet which provides enough protein and energy. However, the production of one of the main sources of protein, animal meat, causes severe impacts on the environment. The present study investigates the production of a vegan-mycoprotein concentrate from pea-industry byproduct (PpB), using edible filamentous fungi, with potential application in human nutrition. Edible fungal strains of Ascomycota (, , , ) and Zygomycota () phyla were screened and selected for their protein production yield.
had the best performance among the tested fungi, with a protein yield of 0.26 g per g of pea-processing byproduct from the bench scale airlift bioreactor cultivation. It is estimated that by integrating the novel fungal process at an existing pea-processing industry, about 680 kg of fungal biomass attributing to about 38% of extra protein could be produced for each 1 metric ton of pea-processing byproduct. This study is the first of its kind to demonstrate the potential of the pea-processing byproduct to be used by filamentous fungi to produce vegan-mycoprotein for human food applications.
The pea-processing byproduct (PpB) was proved to be an efficient medium for the growth of filamentous fungi to produce a vegan-protein concentrate. Moreover, an industrial scenario for the production of vegan-mycoprotein concentrate for human nutrition is proposed as an integrated process to the existing PPI production facilities.
目前全球约有10亿人无法获得富含足够蛋白质和能量的饮食。然而，蛋白质的主要来源之一——动物肉类的生产对环境造成了严重影响。本研究利用可食用丝状真菌，研究从豌豆产业副产品（PpB）中生产纯素真菌蛋白浓缩物，并探讨其在人类营养中的潜在应用。对子囊菌门（ 、 、 、 ）和接合菌门（ ）的可食用真菌菌株进行了筛选，并根据其蛋白质产量进行了选择。
在所测试的真菌中， 在性能方面表现最佳，在实验室规模的气升式生物反应器培养中，每克豌豆加工副产品的蛋白质产量为0.26克。据估计，通过将这种新型真菌工艺整合到现有的豌豆加工行业中，每1公吨豌豆加工副产品可生产约680千克真菌生物量，约占额外蛋白质的38%。本研究首次证明了豌豆加工副产品被丝状真菌用于生产供人类食用的纯素真菌蛋白的潜力。
豌豆加工副产品（PpB）被证明是丝状真菌生长以生产纯素蛋白浓缩物的有效培养基。此外，还提出了一种为人类营养生产纯素真菌蛋白浓缩物的工业方案，作为现有豌豆加工产业生产设施的整合工艺。
