Analysis of environmental conditions effect in the phytochemical composition of potato (Solanum tuberosum) cultivars
Crop productivity and food quality are affected by environmental conditions. The objective of this work was to evaluate the effect of the environment on the concentration of phytochemical components in several potato ... -
Biocompounds content prediction in Ecuadorian fruits using a mathematical model
Anthocyanins, carotenoids and polyphenols are biomolecules that give the characteristic color to fruits. Carotenoids relate to yellow, orange and red colors whereas anthocyanins and polyphenols mainly relate to purple ... -
Control of respiration and color modification on minimally processed potatoes by means of low and high O2/CO2 atmospheres
This study has demonstrated the potential of several controlled atmospheres for reducing the respiration rate and browning in minimally processed potatoes (cv. Monalisa) during a 14-day storage period at 4 ◦C. The gas ... -
Effect of fortification with eggshell powder on injera quality
In Ethiopia there is a severe calcium nutrient deficiency problem. Cereals are appropriate vehicles for food fortification along with eggshell powder (EP), a waste product, which contains a high amount of Ca. The objective ... -
Effect of modified atmosphere packaging (MAP) in the antioxidant capacity of arazá (Eugenia stipitata McVaugh), naranjilla (Solanum quitoense Lam.), and tree tomato (Solanum betaceum Cav.) fruits from Ecuador
This study aimed to determine the effects of the modified atmosphere packaging (MAP) in the antioxidant capacity (AC) of arazá (Eugenia stipitata McVaugh), naranjilla (Solanum quitoense Lam.), and tree tomato (Solanum ... -

New thin-layer drying models for the design and simulation of cassava root dryers and phenomenological study of interaction water-starch during diffusion
In the present work, drying phenomenology of cassava root slices was studied at 55, 65, 75, 85, 95, 105 and 115 degrees C, and at 5- and 6-mm thicknesses. Chemical analysis, X-ray diffraction (XRD) measurements, and ... -
Profile of bioactive components of cocoa (Theobroma cacao L.) by-products from Ecuador and evaluation of their antioxidant activity
The aim of the study was to determine the profile of bioactive compounds in cocoa residues (mucilage and bean shells), and to evaluate their antioxidant activity in two cocoa varieties, Nacional X Trinitario type (Fine ... -
