| Research Abstract |
Traditional fermented foods are potential resources for isolation of micro-organisms, of which functions are expected to have a high potential for development of new biotechnological utilization. In this program we focused on the basic investigation of the traditional fermented foods in Vietnam which are faced on their loss in the process of rapid industrialization and rapid modernization of life.
The preliminary investigation was done during September 6 to 15,1997, and the main investigation was carried out under the cooperation by Thai and Vietnamese' experts.
According to the study of marketed products and information proved by Vietnamese's scientists, we could group traditional fermented foods into four categories : fermented foods from rice, from soy bean, from fish or shrimp and from vegetables. In the fermented foods from rice such as Com Ruou, Ruou Nep (distillled rice alcohol) and Ruou Can (rice wine), a starter cake (yeast cake) are commonly used. Micro flora in the starter cake consists of fungi of the genus Mucor and Rhizopus and yeast of the genus Endomycopsis, Saccharomyces, Hansenulla and Candida, but the microbes is very variable depending on the products. In fermented products from soy bean, Such as Chao (fermented Tofu), Tuong (Miso) and Noo Tuong (Shoyu), fungi belonging to the genus Aspergillus are main microbes, but species of fungi could not be identified during this investigation, expecting the contribution of many kind of species. The traditional fermented fish/shrimp paste, Mam, are fermented by holophilic microorganism.
Generally, it is expected that many kinds of microorganism may contribute the fermentation and are widely diversified because the fermented foods are produced independently from family-size factory. Conclusively, we propose a preparation of an scientific article on the traditional fermented foods in Vietnam comparing those produced in Southeast Asia.
