Hygyenic-sanitary evaluation of flaxseed flour of the Metropolitan Region of Recife (RMR)/ Avaliação higiênico-sanitária de farinha de linhaça da Região Metropolitana do Recife

Abstract

Flaxseed (Linum usitatissimun L.) is increasingly present in grain and cereal stalls in public markets, fairs and in the healthy food section in supermarkets. This is due to the growing demand for natural products, and a healthier nutrition appeal. These so-called healthier foods induce the expectation of reducing the risk of chronic non-communicable diseases, such as cancer, heart disease and those related to carbohydrate restriction. Given the importance that flaxseed is acquiring in the Brazilian market, with greater incorporation in the diet, it is necessary to carry out a study on the hygienic-sanitary quality of flaxseed flour. Ten samples of brown flaxseed flour sold in supermarkets in the Metropolitan Region of Recife (RMR) were collected, with the aim of evaluating the mandatory microbiological parameters, as well as the count of molds and yeasts, to check the sanitary quality and search for foreign material (dirt). It was observed that despite being in microbiological compliance with the legislation in force, the fungal concentration found is higher than the limit allowed by health standards. In the search for foreign material, cotton fibers were found. It is suggested that an identity and quality standard be created for flaxseed flour, and greater sanitary control during processing, to protect against the possibility of cross contamination.
