    The mocaccino-type beverage was made from breadfruit (Artocarpus altilis (Park.) Fosb.) seeds with oat milk (Avena sativa L.) as an alternative to commercial mocaccino, aiming to contribute to the health of its consumers. Sensory, physicochemical, bromatological, and microbiological analyses were conducted, along with the determination of caffeine content and antioxidant activity in the formulation of the mocaccino-type beverage to assess the product's potential. Three roasting treatments were proposed for the breadfruit seeds, which were then evaluated sensorially. The infusion with the highest preference was made from seeds roasted at 200 degrees Celsius for 10 minutes, achieving an acceptability of 85 percent. Using the best infusion, three formulations of the mocaccino-type beverage were made, varying the proportion of infusion and oat milk, and these were evaluated alongside a control made with commercial espresso coffee. The formulation with 60 percent infusion and 40 percent oat milk had the highest acceptability, with 90 percent. This formulation underwent physicochemical, bromatological, and microbiological analyses, including counts of molds and yeasts, total coliforms, and Salmonella, confirming that the mocaccino-type beverage has good sanitary quality under proper storage conditions. Additionally, the caffeine content and antioxidant capacity were determined, which were 3.45 milligrams per-100 grams of sample and 2114.91 micromoles TE per liter of sample, respectively.

    Elaboración y evaluación de un snack nutritivo a partir de lenteja roja (Lens culinaris subsp. culinaris) y harina de avena (Avena sativa L.)

    Today's society, fast-paced lifestyles, stress and unhealthy eating habits affect human well-being, prompting the food industry to develop new products based on legumes and cereals that, despite their high nutritional value, are not used in food development. Snacks are widely appreciated and consumed between main meals, representing one third of the daily energy intake. However, many of these products are high in calories and low in nutrients, which contributes negatively to health, increasing the risk of diseases such as cardiovascular disease, hypertension, obesity and diabetes, among others.In the present work, a "nutritious snack" was prepared and evaluated with a mixture of red lentil (Lens culinaris subsp. Culinaris) and oat flour (Avena sativa L.), using appropriate technology, a yield of 74.89 percent was obtained. Four formulations were proposed and by means of a sensory analysis, the best treatment was determined, containing 65 percent red lentil and 35 percent oat flour. The snack complies with current regulations for this type of product and has attractive sensory characteristics and stands out for its high protein, fiber and low-fat content, which contributes to a healthier lipid profile. In conclusion, its consumption can bring more benefits than commercial products on the market.

    Elaboración de una barra energética a base de quinua (Chenopodium quinoa), amaranto (Amaranthus caudatus L), chocho (Lupinus mutabilis sweet) y avena (Avena sativa) endulzado con jarabe de jícama (Smallanthus sonchifolius) para deportistas de alto rendimiento

    The health of the Ecuadorian population is compromised by the excessive consumption of fast food and unhealthy snacks, resulting from the adoption of unbalanced diets and poor dietary quality. High-performance athletes, when engaging in these behaviors, do not obtain quality nutrients and good digestibility necessary for their training, therefore, Andean products represent an excellent alternative for the elaboration of energy bars due to their high nutritional value. Chocho, quinoa, amaranth, oats and jicama were the selected raw materials. Three energy bars were formulated by adjusting the macronutrients of each raw material to the requirements of high-performance athletes, by balancing equations using the Gauss-Jordan method. After sensory evaluation, the formulation with the highest acceptability was subjected to texture, proximate composition and amino acid profile analysis. Formulation I, sensory outstanding, showed values of 45.10 newtons for both hardness and fracturability, 5.36 millijoules for elasticity and 0.55 millijoules for adhesiveness indicating good support and structure for the bar. In addition, it met the nutritional requirements for athletes, with percentages of 58.53, 10.18 and 15.89 for carbohydrates, lipids and proteins, respectively. Its caloric content of 389.42 in kilocalories covers approximately 12 percent of the recommended daily calories for athletes. The amino acids identified were 17, with glutamate being the most abundant with 61.42 milligrams of amino acid per gram of protein. Essential amino acids totaled 89.55 grams of amino acid per gram of protein, surpassing other formulations based on andean crops.

    Elaboración de galletas a base de harina de higo (Ficus carica) y harina de avena (Avena sativa) utilizando tres tipos de edulcorantes (panela, azúcar blanca y eritritol) para jóvenes adultos de 18-25 años

    Cookies are one of the most desired snacks for both children, youth, and adults. However, a large part of the biscuit industries makes their products from refined wheat flour, butter, highly caloric sweeteners and ingredients whose nutritional contribution is low. In this study, the elaboration of cookies from fig flour (Ficus carica) and oat flour (Avena sativa) using three types of sweeteners (panela, white sugar and erythritol) was proposed for young adults aged 18-25; with the purpose of providing a food with a sensory, physical, and nutritional composition that adapts to the requirements of consumers. For the development of the investigation, different formulations were used in relation to the proportions of fig flour (HH) and oat flour (HA) (30:70, 50:50 and 70:30), in addition to the type of sweetener (panela, sugar and erythritol). To determine the best treatment, sensory parameters (color, odor, taste, texture, and acceptability) were evaluated using an incomplete block design, and textural properties using a Brookfield texturometer. The best formulation obtained was a1b1 (30 percent HH, 70 percent HA and sweeteners). The proximal analysis of the best treatment was obtained: 2.90 percent moisture, 8.23 percent protein, 16.22 percent fiber, 20.77 percent fat, and an energy content of 419 kilocalories per-100 grams of product. The cookie could be an alternative to complement the diet of people between 18 and 25 years of age.

    This project focuses on Andean crops and their influence on the formulation of an energy bar, considering within this group cereals such as Oats (Avena sativa) and the pseudocereals Quinoa (Chenopodium quinoa) and Amaranth (Amaranthus Caudatus L.). The Solver add-in for the Excel spreadsheet was used. Through an adjustment of values within the objective and restriction cells, they manage to give the desired value, finding an optimal value while minimizing costs. Once the formulation was defined, the product was elaborated. The physicochemical analyzes performed were presented in percentage: 5.02 moisture, 1.85 ash, 28.3 fat, 15.9 protein, 13.8 fiber, 35.13 carbohydrate and 458.82 kilocalories of energy. The same ones that met the established standards and norms, except for fat, which had a high value attributed mainly to butter and the presence of nuts within the formulation. The elaborated product presented a very low value of mesophilic aerobes, it is acceptable within the microbiological part, representing a good food safety. The texture analysis was performed in terms of hardness obtaining a value of 1757 grams. The sensory analysis was carried out to obtain a sensory profile and to know which of the parameters the consumer prefers. Through the calculation of the economic feasibility, a net value of 0.75 cents per 75 grams of bar was obtained, through the financial indicators, a viability was obtained since there are positive values.
