Estudo do valor alimentar de algumas plantas silvestres

Abstract

The work constitutes one of the first steps in the investigation of the nutritional value of wild plants used in food and aims to guide the development of agricultural production programs in different areas and the provision of data for nutritional education in order to reduce malnutrition. The work consists of 3 parts: - The first part of an informative character aims to present the 11 plants as spontaneous, emphasizing the specific characteristics of these plants. In this part, the different nutrients are also referred to, highlighting their importance for the human body and the various methods of analysis applicable to their determination. - The second part is to carry out various chemical analyzes of various nutrients on the parts of the plant that are used for consumption. - The third part is the presentation of the results calculated on the absolutely dry sample, where the following aspects stand out: 1- The high fat content (12.3%) and the soluble sugar content (37.3%) give the macuacua fruit an excellent nutritional value. 2- 0 content of proteins (25%) and essential amino acids (37 – 50%) the high content of essential fatty acids (34 - 43%), starch (40%), phosphorus (0.6 - 1.5 ), in beans, places it among the products with the highest food value. 3 -The high protein content (23 - 26 %), the percentage of essential amino acids (37 - 48%) over proteins and phosphorus (1.4 - 1.9%) of plants such as cacana, tseque, guche in good large and medium leaves, give them a satisfactory food value despite the existence of the limiting factor (cellulose) in high contents (60 - 64%).
