1. Effect of high temperature and recovery from stress on crop–weed interaction
ABSTRACT Biotic and abiotic stresses, either individually or in combination, may affect soybean growth and development negatively, besides competitiveness with weeds. This study aimed at evaluating the effect of heat stress and plant recovery on crop–weed interaction by analyzing growth variables. Experiments were set up as replacement series of soybean wi

2. In vitro anticancer and antioxidant potential of Amaranthus cruentus protein and its hydrolysates
Abstract New insights on the use of peptides as therapeutic agents in the treatment of cancer have emerged with reports showing anti-tumour activity of peptides, predominantly derived from animals or microorganisms. Amaranth is a pseudocereal traditionally acknowledged to possess pharmacotherapeutic properties. Thus, the aim of this study was to compare the

3. Amaranth in southernmost latitudes: plant density under irrigation in Patagonia, Argentina
ABSTRACT In Argentina there have been few evaluations of Andean pseudocereal plantings. This study explored the response of Amaranthus cruentus cv Mexicano to different plant densities under furrow irrigation in the lower valley of the river Negro, Patagonia, Argentina. The experimental design consisted of 3 blocks with randomized treatments (subplots), each

6. Development of an organic quinoa bar with amaranth and chia
Abstract Quinoa is an Andean crop with extraordinary nutritional properties. Its high protein content and well-balanced amino acid composition make it a unique food product for health-conscious consumers. The aim of this study was to develop a cereal bar using organic quinoa with amaranth, chia seeds, nuts and dried fruits. Seven bar prototypes were designe

7. Optimization of gluten free biscuit from foxtail, copra meal and amaranth
Abstract Optimization of proportion for minimally processed foxtail millet flour (FMF) (55g or 85%) and copra meal flour (CMF) (10g or 15%) through preliminary trials were done sensorially to have gluten free premix. Optimized premix (60g or 60%) work upon further with amaranth flour (AF) (40g or 40%) in the same way to have gluten free composite mix that w

8. Determination of Six Synthetic Dyes in Sports Drinks by Dispersive Solid-Phase Extraction and HPLC-UV-Vis
A simple, fast and efficient method was developed for determination of six synthetic dyes (Tartrazine, Sunset Yellow, Amaranth, Ponceau 4R, Indigo Carmine and Brilliant Blue) in sports drinks using dispersive solid-phase extraction (d-SPE) with the polymeric sorbent Oasis® HLB. Sample preparation using d-SPE permitted to simplify the procedure and use less

9. Determination of Rare Earth Elements in Some Flower Herb Teas and their Infusions
The aim of this study was to determine the sixteen rare earth elements (REEs) in twelve types of popular flower herb teas and their infusions consumed in China. Microwave-assisted acid digestion was used for all of the samples, and the contents of these elements were determined by inductively coupled plasma mass spectrometry (ICP-MS). The concentrations of R

11. Effect of Amaranth addition on the nutritional composition and consumer acceptability of extruded provitamin A-biofortified maize snacks
The objective of this study was to determine the effect of adding Amaranth leaf powder on the nutrient content and consumer acceptability of extruded provitamin A-biofortified (PVA) maize snacks. Flours of four varieties of PVA maize were composited with Amaranth leaf powder at 0, 1 and 3% (w/w) substitution of, respectively, and extruded into snacks. The as

12. Phosphorus distribution and availability in untreated and mechanically separated biogas digestates
ABSTRACT Biogas digestates contain valuable nutrients but also have high water contents. Di-gestates were sampled from two different biogas facilities before and after solid-liquid separation and were analyzed with regard to their composition and phosphorus (P) fractions. Additionally, to investigate the P fertilizer effects of these digestates in comparison
