Determinação de parâmetros físico-químicos do Açúcar nacional e Sul-africano

Abstract

The present report was carried out at the National Laboratory of Water and Food Hygiene and Food Hygiene, in the Chemistry Department, it lasted 11 months and had two distinct phases which are: learning the techniques used in the laboratory the determination of physicochemical and nutritional parameters and the realization of the work. Taking into account that the professional internship is the first contact with the technical and instrumental reality which must be reconciled with the theory obtained during the learning process. The elaboration of the work consisted of bibliographical research, practical learning experiments, discussion of the results and finally the conclusions. conclusions. The research consisted of collecting information in books, articles and internet related to the theme, the learning phase corresponds to the period the learning phase corresponds to the period in which the quality analysis/tests on the different and finally the work accomplishment phase which consisted in the application of the the knowledge acquired previously. Sugar is consumed every day in our country and in the world, however, the inadequate use has negative effects on the human body. Mozambique, despite to produce sugar is still not enough to meet the demand for that reason we still import, mainly the South African sugar, being the most consumed in relation to national sugar, a fact that motivated the realization of the present work in physical-chemical and nutritional analysis of this food in order to in order to compare the parameters in the analysis made in national and South African samples according to the standards in force in Mozambique. To this end, the following parameters were analyzed the following parameters in accordance with the various methods used at LNHAA, brix degree, ashes, humidity, polarization, vitamin A, colour. According to the results obtained, it is concluded that the national and South African samples are suitable for South African samples are suitable for human consumption since the parameters analysed are within the range required by INNOQ.
