Analogous reserve distribution and tissue characteristics in quinoa and grass seeds suggest convergent evolution
Quinoa seeds are highly nutritious due to the quality of their proteins and lipids and the wide range of minerals and vitamins they store. Three compartments can be distinguished within the mature seed: embryo, endosperm, and perisperm. The distribution of main storage reserves is clearly different in those areas: the embryo and endosperm store proteins, lipids, and minerals, and the perisperm ...
متن کاملDistribution of minerals in quinoa (Chenopodium quinoa Willd.) seeds.
The distribution of minerals in quinoa (Chenopodium quinoa Willd.) seed was examined using energy dispersive X-ray microanalysis (EDX) in combination with scanning electron microscopy (SEM). Phosphorus, K, and Mg coincided in localization in embryonic tissue. Since phytin globoids have been known to localize in protein bodies in embryonic cells of quinoa seed, it is thought that P is attributed...

15 صفحه اولAntioxidant and Antimicrobial Activities of Quinoa (Chenopodium quinoa Willd.) Seeds Cultivated in Korea
The objective of this study was to investigate the antioxidant and antimicrobial properties of quinoa cultivated in Korea and to compare it with imported quinoa from the USA and Peru. The highest amount of total flavonoid contents (TFC) with 20.91 mg quercetin equivalents/100 g was measured in quinoa seed extract cultivated in Korea, while the total phenolic contents (TPC) were significantly hi...
متن کاملChanges in phenolic composition and antioxidant activity during germination of quinoa seeds (Chenopodium quinoa Willd.)
Quinoa seed (Chenopodium quinoa Willd.) has obtained great interest in recent years due to its high nutritional value and its content of natural antioxidants and other phytochemicals with positive biological activity in humans. Their ability as health promoters depends strictly on the processing conditions to which the seeds are submitted. In this work, quinoa seeds were subjected to germinatio...
