This article shows the results of the comparison of using a non-continuous system technology and a continuous system technology in terms of the quality obtained in both processes. The non-continuous system technology produces second class quinoa with a yield of 86 %, and the continuous system technology produces first class quinoa with a yield of 96 %, which represents a significant difference between both systems.

The objective of this study was to conduct agricultural zoning of climate risk for quinoa cultivation. Data from 38 meteorological stations of the National Meteorology and Hydrology Service in Puno region were used. The zoning was based on the development of the water balance model, applying the water requirement satisfaction index (ISNA), for two levels of soil available water capacity (115 mm/m and 145 mm/m). Spatial analysis of the ETr/ETm ratio, obtained from the SARRAZON model, was carried out for each phenological stage through frequency analysis of ISNA values. These data were processed in ArcGIS10.0, using the ordinary kriging interpolation method. Once the maps were generated, they were clipped to the quinoa production zones of the region and classified as follows: for Phase I: low risk (ISNA ≥ 0.65); medium risk (0.55 < ISNA < 0.65) and high risk (ISNA ≤ 0.55), consid...

Quinoa is a very important grain for human nutrition; In recent years, several research studies have addressed its nutritional use; However, one of its main weaknesses is its saponin content, which is an anti-nutrient and has a bitter taste. The debittering process involves the principle of recirculation of large quantities of water, with the purpose of reducing the consumption of this substance, it is important to develop methodologies and equipment that improve the efficiency of these traditional washing methods and reduce the work of operators and processors with the intention of making it less costly. The objective of the present research work was to design and build a quinoa de- saponifier , Amarillo Maranganí variety, to evaluate the effect of washing time (5, 10 and 15 min) and the flow of water recirculated by pumping (15, 30 and 45 L/min), on the elimination of saponin to accep...

The objective of this research was to determinate the consumer response about the degree liking of a beverage in function to flavor and consistency. The beverage was elaborated with pineapple (Ananas comosus) pulp/quinoa (Chenopodium quinoa Willd), in ratio 7:1 (w:w), processed in three heat treatments TP01, TP02 and TP03 (85 ºC x 26 minutes , 90 ° C x 7 minutes and 95 ° C x 2 minutes). The physical-chemical characteristics evaluated were: pH, degrees Brix, viscosity. The sensory evaluation was evaluating with trained judges (panel of 15 judges) to flavor and consistency. The results showed statistically significant differences between the three treatments in terms of viscosity and consistency; in flavor not showed statistically significant differences between treatments. The linking degree for consumers employed people of 16 to 40 years old. The consumer’s response not present sign...

El objetivo de esta investigación fue determinar la respuesta del consumidor respecto al nivel de agrado de una bebida en relación a las características sensoriales de sabor y consistencia. La bebida fue elaborada en base a pulpa de piña (Ananas comosus) y quinua (Chenopodium quinoa Willd), en proporción 7:1 (p:p), procesada mediante tres tratamientos térmicos diferentes TP01, TP02 y TP03 (85 ºC x 26 minutos, 90 ºC x 7 minutos y 95 ºC x 2 minutos). Las características físico-químicas evaluadas fueron: pH, grados Brix y viscosidad. Los atributos sensoriales de consistencia y sabor (global) fueron evaluados con un panel conformado por 15 jueces entrenados.

The objective of this study was to assess the effects of saponins derived from Chenopodium quinoa by-products on methane (CH4) production in a ruminal fermentation system under in vitro conditions. Additionally, the study included the analysis of short-chain fatty acids (SCFAs) and true dry matter digestibility (TDMD). The saponin extracts obtained from three quinoa varieties were Altiplano (AS), Quillahuaman (QS), and Salcedo (SS), and were tested at six different doses (0, 0.2, 0.4, 0.6, 0.8, and 1.0mg/mL) each. Rumen fluid was obtained from two fistulated Junín breed sheep, with alfalfa hay (AH) and a 1:1 mixture of maize and bran (MB) was used as basal substrates. The data were processed in a completely randomized design and replicated three times. The CH4 per dry matter (mL/g DM), after 24h of incubation significantly decreased, acetate molar concentration decreased (p<0.05) with A...

The process of hydrolysis was carried out on a suspension of quinoa flour in water in a proportion of 1 in10 parts of water, previously gelatinized, to which was added an equivalent suspension of enzymes of 1,5 g/1000 g (50% of alpha amylase and 50% protease). With that, proteins were solubilized and starch was reduced to reducing su- gars, obtaining a liquid product at an average concentration of 8,5% that was later con- centrated to 45% of total solids. The hydrolysis process allows, on the basis of 1 kg of quinoa flour, toobtain80 to 85% of hydrolyzed material from20 to 15% of cellulosic residue, proteins and carbohydrates, non-digestible by the enzymes. The experiences that were carried out brought as results the following optimum values of kinetic parameters: Concentration of substrate: 10,0 %; Temperature: 60 ºC; pH: 5,0 and enzyme con- cent...

Se Teniendo en cuenta que un producto, como la “quinua” es lo suficientemente nutritivo y digerible; es necesario que tenga un grado de hidrólisis que permita solubilizar la proteína, almidón, fibras, etc. cambiando sus propiedades organolépticas para hacerlo más aceptable y aprovechable. Por ello la investigación se orientó a determinar los parámetros cinéticos de pH, temperatura y concentración de sustrato que permitan el proceso de hidrólisis de harina de “quinua” en una proporción de 1 en 10 partes de agua, previamente gelatinizada, a la cual se le adicionó una suspensión de enzimas equivalente a 1,5g/1000 g (50% de alpha amilasa y 50 % de proteasa). Con lo cual se logro solubilizar las proteínas y reducir el almidón a azucares reductores, obteniéndose un producto liquido a una concentración promedio del 8,5 %, que fue posteriormente concentrado a 45 % de s...
