PRODUCTOS ELABORADOS CON VERDOLAGA (PORTULACA OLERACEA L.): VALORACIÓN NUTRICIONAL, CONOCIMIENTO, CARACTERÍSTICAS ORGANOLÉPTICAS, ACEPTABILIDAD Y SATISFACCIÓN
Introduction: portulaca oleracea, known as purslane (verdolaga), culturally considered an undergrowth, has multiple beneficial properties allowing to be used as a food, due to its easy access and low cost. There are not many studies on the subject. Objectives: the objective of present work was to prepare food products using purslane as raw material, with adequate organoleptic characteristics. To calculate their nutritional value and to determine the recommended dietary allowance (RDA) percentage they cover. Also, to identify the level of knowledge that a certain population has about purslane and its nutritional properties, and to define the organoleptic characteristics of the foods elaborated, evaluating the degree of acceptability and satisfaction in the population under study. Materials and methods: the study was descriptive, nonexperimental and experimental (pre-experiment), cross-sectional. Three preparations with purslane were elaborated and subjected to tasting: soup (S), omelette (O) and salad (E). Results: tthe caloric value per serving of the preparations was S: 24.2 kcal/200 g; O: 129.2 Kcal/200 g, and E: 116.16 kcal/150 g. The percentages of RDA covered by a serving of each food were: S: 1.21% kcal, 1.31% carbohydrates, 1.96% proteins, 0.54% fats; T: 6.43% kcal, 3.48% carbohydrates, 9.54% proteins, 11.81% fats, and E: 5.8% kcal, 5.06% carbohydrates, 4.28% proteins and 8.6% fats. The values were calculated on referred to the recommended daily intake (RDI), which are: 2,000 kcal, 300 g carbohydrates, 75 g proteins y 55 g fats, defined to a group of adult women and men between 18 and 60 years old. The sample included 50 people with 42 years average age, 58% female and 42%male, 40% with secondary studies, 34% university (N=17), 18% tertiary (N=9) and 8% primary. 76% of the participants presented a low knowledge about purslane and its nutritional properties. The preparations were satisfactory for 82% of the participants and accepted by 90%. Conclusions: due to the suggested nutritional properties and its versatility for its incorporation in various recipes, purslane can be indicated as an excellent alternative for human consumption.
