Physicochemical characterization of sangorache natural colorant extracts (Amaranthus quitensis L.) prepared via spray- and freeze-drying

AIMS Agriculture and Food, 2023
In this study, we sought to prepare sangorache encapsulate (Amaranthus quitensis L.) by spray- and freeze-drying, using three different concentrations (3, 5 and 7%) of the encapsulating agent, maltodextrin. To atomize the powder, we used a Buchi mini spray-dryer B-290 with three inlet temperatures (140, 160 and 180 ℃) and a laboratory freeze dryer with

Pest categorisation of Nacobbus aberrans

EFSA Journal, Volume 16, Issue 4, April 2018., 2018
Abstract The Panel on Plant Health performed a pest categorisation of Nacobbus aberrans (Nematoda: Pratylenchidae), the false root‐knot nematode, for the EU. The nematode was originally described from the American continent. Due to differences in host range as well as molecular variability among populations, N.

From cacti to carnivores: Improved phylotranscriptomic sampling and hierarchical homology inference provide further insight into the evolution of Caryophyllales

American Journal of Botany, Volume 105, Issue 3, Page 446-462, March 2018., 2018
Premise of the Study The Caryophyllales contain ~12,500 species and are known for their cosmopolitan distribution, convergence of trait evolution, and extreme adaptations. Some relationships within the Caryophyllales, like those of many large plant clades, remain unclear, and phylogenetic studies often recover alternative hypotheses.

Studies on flowering time and photoperiod sensitivity in domesticated and wild amaranth species (Amaranthus spp.) [PDF]

, 2023
Flowering time plays fundamental roles in the local adaptation and agricultural productivity of the crops. Photoperiodic response regulates the time of flowering by adjusting the response of plant circadian rhythm to environmental signals.

The Amaranth Genome: Genome, Transcriptome, and Physical Map Assembly

The Plant Genome, Volume 9, Issue 1, March 2016., 2016
Amaranth (Amaranthus hypochondriacus L.) is an emerging pseudocereal native to the New World that has garnered increased attention in recent years because of its nutritional quality, in particular its seed protein and more specifically its high levels of the essential amino acid lysine.
