    Optimización del proceso de troceado de carnaza residual de una curtiembre en la ciudad de Ambato para la elaborar una harina para consumo animal

    Tanneries generate tons of solid and liquid waste during the production of leather, which causes environmental and health problems, in addition to being a waste of money for the companies to dispose of. The solid waste that is normally sent to the landfill consists of massive quantities of meat, skin, and fat, especially the fleshing from the deboning process, which makes it a perfect raw material to produce flour or protein bases. The following work is intended to optimize the process of cutting the meat obtained from tanneries in the city of Ambato, to produce greaves, which will serve as the basis for obtaining some flour for animal consumption. To obtain the greaves, 4 kilograms of meat was cooked at 60 degrees Celsius with contrasting times and sizes of pieces, using at the end pieces of 3x3 centimeters and 90 minutes, which were dried at 90 degrees Celsius for 10 hours in an oven to eliminate most of the humidity. The flour resulting from the grinding and sieving of the crackling was analyzed by physicochemical analysis obtaining data on moisture, ash, protein, pH, acidity index, and saponification index within the parameters of the INEN 1829:2014 standard, on the other hand, the percentage of fat is higher than allowed; therefore, it is possible to use this flour as a protein base, and further, improve it by mixing it with other products to obtain a more nutritious balanced.

    Optimización de hidrólisis básica para la obtención de gelatina a partir de virutas cromadas provenientes de una curtiembre de la ciudad de Ambato

    The leather industry generates various environmental concerns due to the amount of highly polluting waste. Among them are solid wastes, which are deposited in landfills or around tanneries. Because these residues contain Chromium (III), there are high possibilities that this element oxidizes into Chromium (VI). Chromium (VI) is considered a toxic and carcinogenic element. It is for this reason that alternatives are required that seek to take advantage of such waste to generate a value-added product. In the present study, the basic hydrolysis process with MgO was optimized to obtain gelatin from chromium shavings. For this, a factorial design was carried out whose factors were the concentration of MgO and time, each one with three levels. In addition, the amount of chromium was quantified and the strength of the gel was determined, with some parameters related to the mechanical properties of the gelatin. The results of the analysis of variance showed that both the reaction time and the MgO concentration are factors that affect the gelatin yield as well as its hardness. Finally, a surface design was carried out whose results showed that under conditions of 6 percent MgO during a reaction time of 5.7 hours, an estimated maximum yield of 34.41percent was achieved.
