Fermentação do tipo chucrute

: uma abordagem com sabores tradicionais portugueses

Abstract

The origin of fermented products is diffused in time, and after drying, it is the oldest food preservation process. Fermentation is a process by which foods can be produced that varies depending on the type of fermentation used. Nowadays, fermented vegetables are the result of an industry that controls parameters such as the ingredients, the temperature, salt addition and concentration. To the final product condiments can be added to make it more palatable and assist in the fermentation process. Although fermented vegetables are appreciated and regularly consumed in countries such as the United States, Germany or Asian countries, in Portugal these products are not as popular, and there isn’t any fermented vegetable product based on foods and typically national flavorings. From a nutritional point of view fermented foods can be interesting. Its digestibility can be improved, the bioavailability of certain nutrients can be increased and it is a potential source of probiotics. In the course of the present study, based on pointed cabbage, several fermentation processes were elaborated creating a protocol of valid fermentation using as base traditional flavorings of Portuguese cuisine. Afterwards, validation studies of the created product were carried out, with the elaboration of a focus group and an interview with an acknowledged chef. The results achieved in the fermentations were satisfactory. The organoleptic characteristics of the final product were in line with what was expected. The results obtained from both the focus group and the chef interview demonstrated that the final product is potentially pleasing to consumers and has culinary applicability. There were also a number of open questions that could be addressed in further work to improve the product. Overall, all objectives were met.
