AbstractThe purpose of this research is to provide an in-depth analysis of the commodification, authenticity, and sustainability of culinary legacy as an instance of intangible cultural legacy, as well as how to subsequently compete with excellence and sustainability in the midst of a modern, global era of business without the loss of authenticity value. Herein is revealed the application of true local culture amid commercialization and modernization, differentiating between the authenticity and that which is out-of-sorts with local identity. The controversy of contextualization, the discussion of what is necessary, and the commodification of traditional food, namely the traditional foods of Riau Malay, to respond to the demand of a global market, are areas of interest in this study, as well as how the traditional foods of Riau Malay may compete with excellence and sustainability in a global market while retaining its authenticity values. The methodology used in this research is qualitative phenomenological; the interviews were carried out from the informants who were cultural figures of Riau Malay, social figures, and business actors in the traditional Riau Malay food industry with resulting evidence that confirms the necessity of heritage value of traditional Riau Malay foods, commodification in the area of globalization, without necessitating any loss of authenticity elements. The cultural heritage of traditional Riau Malay foods is introduced in two different types, cake pastry and main course savory dishes, and divided into two categories, everyday cuisine and cuisine for ceremonies or rituals. Riau Malay natives have customs and culture involved in the preparation and processing; presentation and consumption of the food may also be seen in the efforts in preparing such a traditional menu. The findings of this study are expected to contribute to the literature and research interest in food culture.
