Summary In a study of tempe made by fermenting quinoa ( Chenopodium quinoa Willd.) with Rhizopus oligosporus Saito, the interaction between the substrate and the fungus varied according to the raw material used. Low‐temperature scanning electron microscopy confirmed that hyphal infiltration in quinoa was normally limited by the seed coat, but a massive penetration was found in fragments of quinoa where the testa was broken. This finding has implications for the texture and quality of tempe fermentation of grains and pulses.
