Clarificación del jugo de chamburo (vasconcellea pubescens) mediante la utilización de 3 tipos de clarificantes

Abstract

In the present investigation the clarification of the chamburo juice obtained of the Guazazo Community from Chimborazo Province and Guaranda Town from Bolivar Province. It was developed with different clarifying agents. Being a poorly cultivated fruit, but with rich nutritional properties, especially vitamins and antioxidants, giving added value, we worked with 12 experimental units that were subjected to the following statistical analyzes: Analysis of Variance (ADEVA), separation of means by Tukey (P<0.05) and sensory analysis by the rating test method. The control treatment (T0) was the juice without any clarifying agent, the second treatment was (0.25 g/l) quitosano (T1), the third was (0.04 g/l) albumin (T2) and the fourth was (0.2 g/l) of gelatin (T3) which were analyzed at day 1,10 and 21. Chemical physical analyzes reported highly significant differences, the one with chitosan (T1) whose value at 21 was 303 being the best for turbidity, 33 NTU, in terms of color the best treatment with gelatin (T3) 3008.25 Pt/Co. The brix and pH degrees values showed a slight decrease in all treatments. Microbiological analyzes of clarified chamburo juice showed no pathogenic microorganisms, observing that the parameters required by the standard are being met (INEN 2337:2008). Finally, the sensory analysis treatment with gelatin (T2) had a good acceptance. We conclude that the best results were obtained for turbidity in the quitosano treatment, however, the best treatment considering all the parameters was the gelatin treatment that presented 3008.25 Pt/Co, 8.73 brix degrees, 4.0 pH, a color rating 4.14, smell 4.21, flavor 4.5 and acceptability 3.86 points out of 5. In addition, a greater profitability was established in the elaboration of juice clarified with gelatin obtaining a cost benefit of $ 1.42; that is, for every dollar invested a profit of $ 0.42 is obtained, being the most viable and profitable of the treatments.
