    Modelado matemático de la cinética de degradación térmica del color de la cereza china (Dovyalis abyssinica (A. Rich.) Warb.) en la elaboración de mermelada

    Currently, color is considered a measurable quality criterion in foods such as nutritional quality, sanitary condition, colorant concentration, degree of maturity, quality control and process automation. The development of mathematical models to determine the loss of color of foods in enzymatic or non-enzymatic reactions was also carried out, since it allows predicting their behavior as a function of time and temperature. The process included the determination of the ripening index of Chinese cherry (Dovyalis abyssinica (A. Rich.) Warb.) as well as its nutritional composition, physicochemical characteristics and antioxidant activity. From the best prospectus, pulp was converted to analyze its color change in CIELab space by Luminosity, Chroma and Hue during jam making at four different temperatures, 120, 130, 140 and 150 Celsius degrees. The study indicated a higher luminosity at ripening stage three, which after the thermal process suggests a line regression for the loss of luminosity, chroma, hue angle and overall color variation values. As the thermal process progresses from intense orange and red colors to darker, paler and less intense colors, using an Arrhenius model, the changes in the values of these factors conform to a first order reaction. The results revealed that the Chinese cherry has a valuable nutritional composition, antioxidant activity, as well as physicochemical characteristics that technologically influence the production of jam.
