This study was designed to determine the contents of total polyphenols, flavonoids, flavonols, flavanols, and anthocyanins purple corn (Zea mays L.) extracts obtained with different methanol:water concentrations, acidified 1% HCl (1 N). Another objective antioxidant activity by 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), ferric reducing power (FRAP), deoxyribose assay, individual phenolic compounds high-performance liquid chromatography...
Abstract Many epidemiological studies have shown the benefits of a diet rich in fruit and vegetables to human health for prevention various diseases associated with oxidative stress, such as cancer cardiovascular diseases. Anthocyanins, natural pigments belonging group flavonoids, are common components diet, they present many foods, fruits, vegetables, especially berries. Their use colorants has considerable interest because their coloring properties. Moreover, an antioxidant activity....
Plant-based beverages, commonly referred to as functional have the potential improve health since they contain bioactive components. A study was conducted analyze nutritional and profiles of beverages marketed in United States Peru, based on different ingredients utilized. The determination content compounds carried out according validated methods. antioxidant activity assessed DPPH FRAP assays. results showed that a low caloric contribution, while were characterized by high such...
This study aimed to evaluate the daily use safety and instrumental efficacy for sebum control of a cosmetic elastomer-type formulation containing vegetable seed oils Plukenetia huayllabambana, Physalis peruviana L., Bertholletia excelsa. Assessments were conducted using skin irritation index Sebumeter® SM 815 from Courage + Khazaka Electronics GmbH, Cologne, Germany. Sebum was determined in three groups volunteers seated room at temperature 26 ± 1 °C. The forehead area divided into two...
The objective of this study was to optimize different vacuum drying conditions for cocoa pod husk and bean shell in order enhance these by-products commercial applications. To carry out the optimization, response surface methodology applied using a Box-Behnken experimental design with 15 experiments which temperature (X1), time (X2) pressure (X3) were established. variables content total polyphenols, flavanols radical scavenging activity evaluated extracts experiments. Temperature (50-70...
Sinami (Oenocarpus mapora H. karst) is the fruit of a native palm from Amazon region. source bioactive compounds and, mainly, vegetable oil rich in unsaturated fatty acids and phenolic compounds. In present study, supercritical-CO2 (SC–CO2) extraction was applied to obtain oil. Parameters such as pressure (P) temperature (T) were optimized determine conditions allow highest yield Also, quality values oils peroxide value index (POV), free (FFA), dienes, trienes assessed, acid profiles...
Sacha inchi seed oil is a food matrix rich in bioactive constituents, mainly polyunsaturated fatty acids. In this study, the characteristics of color, carotenoid content, tocopherols, and volatile aroma compounds eight sacha (Plukenetia volubilis L.) accessions were evaluated. Results showed that obtained from presented lightness chroma 91 to 98 units 6 10 respectively, while hue angle ranged between 93 97 units. The total content different 0.6 1.5 mg/kg, γ- δ-tocopherol 861.6 1142 mg/kg 587...
The chemical composition and CIELAB color parameters of oil from three aguaje morphotypes ( Mauritia flexuosa L.f.) extracted by supercritical carbon dioxide was investigated. By chromatography (HPLC GC), spectrometry (UV/vis), digital image colorimetry (digital camera), carotenoids, tocopherols, tocotrienols, fatty acids, total polyphenols, space were analyzed. These findings showed that the obtained morphotype 3 superior in several analytes (carotenoids, oleic acid, β-sitosterol,...
Mauritia flexuosa L.f. is a palm tree which presents great morphological variability (morphotypes), represented mainly by the mesocarp color of its fruits. The objective study was to characterize physicochemical and antioxidant properties three morphotypes ("Yellow", "Colour" "Shambo") greater economic importance in Peruvian Amazon. "Shambo" showed significantly high content bioactive compounds (total phenolics, flavonoids carotenoids) DPPH radical scavenging activity compared "Yellow" (p ≤...
The sinami palm (Oenocarpus mapora H. Karst) is a plant from the South American Amazonia that has great potential for industrial applications in development of functional foods, nutraceuticals and cosmeceuticals. In this manuscript, physicochemical properties, total polyphenol content antioxidant activity oil was obtained using four extraction systems, namely expeller press (EPE), cold (CPE), ultrasound-assisted (UAE) supercritical fluid (SFE), were studied compared. oxidative stability...
Context: In the Valley of Ica-Peru, seeds fruit Vitis vinifera L. (grape) are residues from Pisco Industry, and due to their bioactive compounds, they can represent a new economic sustainable activity for population mentioned Valley. Aims: To characterize polyunsaturated fatty acids Ica Valley, Peru determine antioxidant in vitro. Methods: The oil five grape varieties (Quebranta, Moscatel, Torontel, Mollar, Italia) was obtained by ethereal extraction with ultrasound. profile characterized...
Introducción. El citocromo CYP2C9 metaboliza, aproximadamente, el 15 % de los fármacos prescritos. Su gen presenta alelos cuyas frecuencias difieren entre grupos étnicos y poblaciones. Los CYP2C9*2 CYP2C9*3 dan cuenta una enzima con actividad disminuida cuya frecuencia no ha sido determinada en la población mestiza peruana.Objetivo. Caracterizar las variantes *2 (rs1799853) *3 (rs1057910) del muestras peruana provenientes Lima, Tacna Junín.Materiales métodos. Se hizo un estudio descriptivo,...
Cañihua (Chenopodium pallidicaule Aellen) es un grano andino que está ganando interés como alternativas nutritivas sin gluten frente a los cereales convencionales de cara las personas con trastornos relacionados al gluten. El objetivo la presente investigación fue elaborar pan libre base harina cañihua y evaluar su aceptabilidad sensorial. Se propusieron elaboraron tres formulaciones en se variaron porcentajes (7,6% 9,5% 8,3%), almidón yuca, (19%, 21% 15,4%), suero leche (3,8%) goma xantán...
The polymorphic variants of CYP1A1 and the deletion GSTM1 are present in Peruvian mestizo population. Wild type mutated genotypes (WT/*2A *2A/ *2A) were identified, whose allele frequencies 0.31 (T allele) 0.69 (C allele), respectively; 53% with wild (+) 47% null . frequency Iquiteño emigrants was 0.72 CYP1A1*2A 25% (-); from Lima 0.67 33% (-). Hardy-Weinberg equilibrium test for studied population showed that both out balance, p > .05. presence risk polymorphism gene high, which...
In Peru, wheat (Triticum aestivum L.) is one of the main resources in food industry; however, due to its low harvested area, it second most imported cereal. The quality flour was studied verify that has desirable characteristics for preparation bakery products. commercial and monovarietal flours assessed by measuring their physicochemical rheological parameters, as well gluten content protein fractions. Eight four (Barba negra, Candeal, Espelta, Duro) from Peru were evaluated. Commercial...
Sinami (Oenocarpus mapora H. Karst), a native fruit found in the Amazon region of South America, has high nutritional value and is rich lipids. However, processing sinami generates large volume agro-industrial waste, mainly composed seeds. Our research comprises proximal analysis seed its phenolic compounds their antioxidant activity. The chemical revealed moisture but low protein, fiber, lipid content. Furthermore, extracts showed vitro activity against 1,1-diphenyl-2-picrylhydrazyl radical...
