Résumé
Garri is a popular food in Nigeria derived from the fermentation of the mash obtained from the enlarged root of the cassava plant, Manihot esculenta Crantz. As currently produced, the mash used for garri production is spontaneously fermented; on account of this, there is great variability in the organoleptic properties and the quantities of residual cyanide in the garri from Nigeria. The use of starter cultures can help ensure uniformity in these properties if dry carriers can be found on which the fermentative organisms can survive for extended periods so as to facilitate the transportation of their carriers to the many small and scattered garri producers. We therefore studied the survival, singly or mixed, on dry starchy substrates derived from locally available crops, of Lactobacillus co-ryneformis, Lact. delbruckii, and Saccharomyces sp., which are associated with garri production, as carriers for these organisms. After 16 weeks of storage, between 75% and 85% of the organisms survived on yam, coco-yam, cassava in that order, whereas between 40 and 65% survived on rice and garri. Refrigeration at 4 °C did not improve the survival of the organisms, when compared to room temperature (30 °C) for the organisms stores on yam, coco-yam, and cassava. However where the organisms were stored on rice and garri, refrigeration improved the survivability of the organisms by between 10 and 20%.
