    The use of waste of plant origin as raw materials plays a fundamental role in the economic and social well-being of Ecuador. The research was developed with the objective of determining the presence of secondary metabolites and their potential phytotoxic activity from balsa leaves (Ochoroma pyrdamile) for the production of bioherbicides. Extracts were obtained by means of maceration and placed in a rotary evaporator at a temperature of 45 °C with an atmospheric pressure of 175 mbars for the respective phytochemical screening and analysis of the phenolic content. The allelopathic effect of balsa extracts on lettuce seeds (Lactuca sativa) was evaluated. The aqueous and ethanolic fractions of teak leaves were used as part of the treatments to contrast the allelopathic effects of the bolla leaf extracts. A completely randomized design was used with the inclusion of 3 concentrations of the extracts in their two aqueous and ethanolic fractions (500, 1500 and 2500 mg-L-1), in each treatment the variables number of germinated seeds, percentage of germination, allelopathic response index, length of the radicle, hypocotyl and cotyledons. A flowchart and diagram for pilot plant production were developed according to each of the processes applied to obtain the extracts. The results show a high presence (+++) of saponins, tannins, reducing sugars in the aqueous and ethanolic phases in the extracts of balsa leaves. The greatest allelopathic effect occurred at concentrations of 2500 mg/l of the ethanolic fractions of both plant species, being less than 44%. The material balance of the extracts from the leaves of both shrub species show a yield of 6.08% (teak) and 5.94% (raft). The fractions of the ethanolic extracts of the balsa leaves showed an allelopathic effect on the lettuce seeds.Keywords: Balsa, bioherbicide, allelopathic effect, metabolites, screening, teak.

    Pseudo-cereals in recent years have gained great commercial and consumer interest, as well as their use in the food industry for their properties, in turn, aromatic herbs cover an important demand in the national market of Ecuador. The objective of this research was to evaluate the effect of quinoa (Chenopodium quinoa), with two types of aromatic herbs, lemon verbena (Cymbopogon citratus) and mint (Mentha piperita L.), in the production of Ale-type craft beer. A completely randomized experimental design with a bifactorial AxB arrangement was used. The physical-chemical variables (ºbrix, density, pH and OH) and sensory variables (color, odor, vivacity, transparency and bitterness) were evaluated, for the sensory analysis, the participation of thirty semi-trained tasters was provided to them. Structured descriptive test in which the tasters gave quantitative values proportional to the intensity they perceived in each of the attributes evaluated in the descriptive analysis, later for the analysis of the results, a non-parametric analysis of variance was applied and comparison of averages according to the cases using the Kruskal Wallis contrast test. The results showed that the physical-chemical variables degrees Brix and pH presented a p <0.05 while the variable density and OH were not statistically different between the treatments, on the other hand, the results of the sensory analysis demonstrated in the attributes color and smell a p> 0.05 on the contrary the other attributes if they were statistically different from each other. The treatment that presented the best acceptance was T6, which in its proximal composition showed a pH value of 3.76; acidity 0.3; and alcoholic degree 1.31 ºGL. It was possible to determine that the inclusion of brewing adjuncts (quinoa, lemon verbena and mint) influenced the physicochemical and sensory parameters, while the best T6 treatment (30 % quinoa + 2 % mint) reported microbiological quality with values of 42 CFU / ml in mesophilic aerobes and 0 UP / ml for molds and yeasts, which are within the Ecuadorian technical standard INEN 2262.

    CALIDAD FISICO-QUÍMICA Y SENSORIAL DE UN NÉCTAR DE MANGO ( Mangifera indica L ) ELABORADO CON GEL DE SÁBILA ( Aloe Vera )
    (INGENIERO INDUSTRIAS AGROPECUARIAS, 2021) ANDRADE MACÍAS TITO GUILLERMO ; YUNEZ RODRIGUEZ ALEXANDRA CAROLINA
    The purpose of this research was to evaluate the use of proportions of aloe vera gel (Aloe vera), on the physical-chemical, sensory and microbiological quality of a mango nectar (Mangifera indica L.), which was carried out in the Laboratory of Agroindustrial Processes of the Faculty of Zootechnical Sciences, Chone extension; A mango nectar was made using the Tomy atkins variety where the pulp was used, adding 5, 10 and 15% aloe vera gel. A completely randomized design was applied where four treatments were studied including a control with three replications. The results of the physical-chemical parameters were 14.20 ° Brix, pH values that vary between 4.13 and 4.57, acidity in citric acid with values between 0.62 and 0.72 g / 100 mL of citric acid and viscosity with values between 364 to 471 mPas; parameters that meet the requirements stipulated in the INEN 2337: 2008 standard for nectars, juices and fruit and vegetable beverages. The percentages of aloe gel used helped to obtain excellent stability in the mango nectar. The T3 that had 15% aloe vera gel in its formulation resulted in lower solids separation with a value of 0.9%, and at the sensory level it also resulted in greater acceptance by the panelists. The microbiological analyzes performed on the most widely accepted nectar were acceptable, with the absence of microorganisms

    CALIDAD FÍSICO-QUÍMICA DE LA HARINA DERIVADA DE TRES VARIEDADES DE ZAPALLO PRODUCIDAS EN EL CANTÓN ROCAFUERTE, PROVINCIA DE MANABÍ
    (INDUSTRIAS AGROPECUARIAS, 2022) LOOR SOLÓRZANO MAYRA JOSSENKA ; PALACIO INTRIAGO JOSSELYN GEMA
    This research consisted of obtaining flour from the three varieties of pumpkin that are most produced in the Rocafuerte canton (common pumpkin, pepo and macre), to which the yield of the flours, the physical-chemical composition, antioxidant capacity and total carotenoids, instrumental sensory evaluation (colorimetry and hardness by methods), in addition, the different food uses that can be given to pumpkin flour are considered. For the development of the research, the pumpkin samples were subjected to a process of selection, classification, sectioning, dehydration at 60°C for 12 hours), and grinding at 210mm. The results showed that the flour extracted from the macre squash reached better averages in terms of fat 8.35%; ash 13.45%; moisture 24.39% and protein 17.70%; the common pumpkin flour reached better results in terms of NDF 19.76% and FDA 8.16%, the best carbohydrate content was for the flour obtained from the pepo pumpkin with a value of 33.85%. The three varieties of flour presented antioxidant capacity, reaching a higher average for common pumpkin flour with a value of 8327 mg/L with an inhibition of 58.90%; the highest content of carotenoids was obtained by the flour extracted from the macre squash with a value of 3387.68 g/100g of sample.
