Análises bromatológicas de missô artesanal

Resumo (EN)

Objective – To carry out bromatological analyzes of moisture, proteins, pH and ash in artisanal miso. Fermentation is a biotechnological process that has been used to modify and produce food since ancient times. In the last two decades, interest in the beneficial effects of fermented foods on human health has increased and made this food category increasingly popular, especially in the East. In the market there is a wide variety of soybean-based pastes fermented by microorganisms, popularly known as miso. Methods – The analyzes carried out were direct drying in an oven at 105°C degrees to determine the humidity (%) and calcination in a muffle for ash (%), determination of pH by means of the pH meter and analysis of proteins through the Biuret test. Results – In the present study, the samples obtained a moisture content between 52.71% and 60.48%, ash content ranging from 1.12% to 22.7%, pH between 5.35 and 8.68, and a content of proteins ranging from 11.1% to 13.2%. Discussion – The results obtained with the analyzes of other studies were interpreted and compared, in addition, some questions of the bromatological field of the researches of the compared studies and the limitations of the present work were pointed out. Conclusion – The fermentative process of food with microorganisms results in a differentiated product that can be beneficial to health with different organoleptic characteristics. Our results were partially similar to other researches and more studies are needed to investigate the microbiome and other physicochemical characteristics in fermented soy products.
