Tropaeolum majus L. is a native plant to South and Central America, used since ancient times by our ancestors to combat different diseases. Glucotropaeolonin is one of its main components, which when hydrolyzed forms benzyl isothiocyanate (BIT) that promotes cellular apoptosis (programmed cell death in cancer cells). Therefore, the present research aims to evaluate the effect of the pressure and temperature of benzyl isothiocyanate extraction by supercritical CO2 from Tropaeolum majus L. The extraction was carried out in a supercritical fluid extractor equipment Speed SFE BASIC Brand: Poly science, the leaves of Tropaeolum majus L. were ground for one hour and lyophilized until obtaining a humidity of 6%. The extraction with supercritical CO2 was carried out with pressures of 200 and 300 bar, temperatures of 50 °C, 60 °C and 70 C, obtaining by the conjugation of these six treatmen...

The content of phenolic compounds and antioxidant capacity in three colors of petals cress(Tropaeolum majus L.) was evaluated. Petals colors red cress, orange and yellow were driedat room temperature; then they were conditioned for extracting its bioactive components,which were quantified showing significant difference (p<0.05) between colors. The highestconcentration of total phenols is in the orange color, followed by red and yellow (917.05;799.35 and 442.02 mg AGE/g sample). For quantification of total flavonoids, the highestcontent is in the red, followed by orange and yellow (2.184; 1.185 and 0.867 mg QE /gsample). As for the total tannins, the highest content is in the red followed by orange andyellow (342.92; 333.77 and 291.53 mg ATE/g sample). With respect to the antioxidantcapacity by DPPH and ABTS methods, the highest content is in the orange color, followed by red and yello...

Carotenoids were extracted from the petals of yellow nasturtium flowers (Tropaeolum majus L.) with hexane, chloroform and petroleum ether at 12, 24 and 48 hours; The highest yield was obtained with chloroform at 24 hours, which was purified to be solubilized with olive oil. It was then microencapsulated with maltodextrin and gum arabic. The dispersion was carried to a Mini Spray Dried B-290 at drying temperatures of 130 °C, 150°C and 170 °C; In the microencapsulation the % recovery of total carotenoids was evaluated (p<0.05) due to the interaction of the encapsulating agent and the drying temperature, the highest recovery rates were 74.10 % and 83.76 % At 130 °C and 150 °C respectively, with gum arabic; No difference (p>0.05) was found in antioxidant activity ranging from 393.00 to 470.97 μmol TE/g. shows. With regard to % humidity, % hygroscopicity, bulk density (g/cm3) and ...

The research aimed to develop a children's pumpkin compote, functional, inexpensive, preservative-free and of considerable shelf life. The effect of incorporating xanthan gum (XG) was evaluated at three concentrations (0.10%, 0.15% and 0.20%) on its rheological properties. Sensory characteristics were applied to 60 panelists (30 undergraduate students and 30 children between 2 and 3 years). Its physical, physicochemical, and microbiological characteristics were determined. With the pH values was estimated the shelf life of pumpkin compote using accelerated testing method. The product was stored at 20 °C, 30 °C and 40 °C for 0, 10, 20, and 30 days. The results show the pumpkin compote presented non-Newtonian behavior, pseudoplastic, and was adjusted to the Ostwald Waele model (R2 > 0.98). Compote formulated with 0.15% of XG was conceived as the best treatment, with a "Like" scale fo...

Background. Artichoke (Cynara scolymus L.) residues are a rich source of phenolic compounds, but these compounds are susceptible to external factors. Therefore, nanoencapsulation by ionic and ultrasound-assisted gelation techniques can be used as an alternative to preservation. This work aimed to determine the effects of the interaction of the following variables: chitosan (Ch) concentration, sodium tripolyphosphate (TPP), Ch/TPP ratio, pH, and sonication time to ensure high encapsulation efficiency (%EE). Materials and methods. Optimal nanoencapsulation conditions were evaluated using a 25–1 fractional factorial design to maximize nanoencapsulation efficiency (%EE) using multivariate regression analysis. Results. The model was adequate with R2 = 0.998. The optimum conditions for nanoencapsulation were Ch (0.28%), TPP (0.29%), Ch/TPP (5/1), pH (4.9) and sonication time (4.79 min). Unde...

Business sustainability has become a global imperative in response to the environmental, social, and economic challenges facing our world. In this context, the measurement and evaluation of business sustainability have become crucial to guide the actions of organizations towards more responsible and sustainable practices. However, the lack of specific measurement instruments for specific regional contexts may limit the ability of companies to evaluate and improve their sustainability performance. In this paper, we present the design of a business sustainability measurement method adapted to the context of Tarma, Peru. Tarma, a region located in the heart of the Peruvian Andes, is characterized by its cultural, environmental, and economic diversity, making it a unique context to address business sustainability. This article proposes a method for measuring business sustainability based on ...

The Mantaro Valley in Peru is an inter-Andean River valley, through which the Mantaro River passes. Approximately a population of one million inhabitants live here. Currently, the damage caused by the use of non-renewable energy sources is very evident, both to the environment and to the local economy, which will become unsustainable in the future. That is why we want to critically study the implementation of renewable energy projects that support the generation of electricity and other types of energy in this area. However, this has some positive and negative elements. In this paper, we apply a PEST-SWOT analysis to evaluate the balance of each of these aspects. Furthermore, we use an evaluation in the form of single-valued neutrosophic numbers, which allow us to capture the uncertainty and indeterminacy in this decision-making problem.

The main purpose of this evaluation is to analyze the economic viability of the implementation of circular models in agriculture in Tarma, Peru. This involves examining the costs and benefits associated with the adoption of circular practices, as well as identifying possible barriers and opportunities for their implementation at the local level. By better understanding the economic landscape, it will be possible to inform decision-making both at the government level and at the level of individual farmers. For the analysis, we have a committee of 30 experts who will evaluate the relationship between variables that positively or negatively affect the implementation of these models in the town. The tool selected for the analysis is Neutrosophic Cognitive Maps, which includes an indeterminacy component within the calculations. This allows greater accuracy in the results since indeterminacy i...
