“…(Villarrica). Similar values were previously reported by Wright et al [11] and other authors [22] [23] with moisture values between 8.2 to 16.6 g/100 g d.m. The highest ash and crude fiber contents were found in the southern zone, being Villarrica the one with highest values (3.74 and 2.88 g/100 g d.m of ash and crude fiber, respectively).…”

“…for Ancovinto (North-dry zone) and Villarrica (South-humid zone) seeds, respectively. Repo-Carrasco-Valencia et al [22] reported that the total flavonoids content of quinoa from Peru was 11.6 -55.5 mg QE/100 g which was higher than that found in this study. The antimicrobial activity of flavonoids is largely due to their ability to penetrate biological membranes [10].…”

“…(Table 1). Repo-Carrasco-Valencia et al [22] working with quinoa from Perú found similar values between 11.32 and 14.72 g/100 g d.m. Interestingly, protein content of quinoa from all the zones was higher compared to the flours of cereals like rice, maize, and rye (containing 8 to 11 g/100 g d.m.…”

Antimicrobial potential of quinoa seeds from six diverse seeds, grown in three distinctive geographical zones of Chile, was correlated with their total phenolic content (TPC), total flavonoid content (TFC) and total saponin content (TSC). The six seeds were Ancovinto, Cancosa, Cahuil, Faro, Regalona and Villarrica. A significant influence of quinoa source on chemical composition of seeds was observed. Extracts of all quinoa samples showed antimicrobial activity in the range of 8.3 -14.8 mm inhibition zone for E. coli and 8.5 -15.0 mm inhibition zone for S. aureus. Cancosa seeds had the highest antimicrobial action. The TPC and TFC ranged from 3.71 to 16.55 mg GA/100 g d.m. and 7.77 to 14.37 mg QE/100 g d.m., respectively. TSC varied from 1.78 to 3.08 g/100 g d.m. A correlation between TFC and antimicrobial activity was found. In conclusion, the six types of quinoa seeds were identified as potential sources of antioxidant compounds and antimicrobial activity.

Grains of amaranth (Amaranthus caudatus) contain from 2.68% to 7.49% (Repo-Carrasco-Valencia et al 2010) of crude fibre, and 20.6% of dietary fibre. It is composed of lignins, cellulose, and hemicelluloses (Grajeta 1997).…”

Piłat B., Ogrodowska D., Zadernowski R. (2016): Nutrient content of puffed proso millet (Panicum miliaceum L.) and amaranth (Amaranthus cruentus L.) grains. Czech J. Food Sci., 34: 362-369.Puffed grains of the varieties of proso millet (Penicum miliaceum L.) and amaranth (Amaranthus cruentus L.) were evaluated as a source of nutritional compounds. The process of grain puffing was performed in prototype equipment of the "Szarłat" company. The analysed mean values for puffed grains were starch (proso millet 72.58%, amaranth 55.53%), fat (proso millet 8.43%, amaranth 8.99%), proteins (proso millet 13.89%, amaranth 14.04%), amino acids (proso millet 48.30 g/kg, amaranth 54.03 g/kg), crude fibre (proso millet 4.29%, amaranth 4.47%), and its fractions, as well as the total polyphenol content (proso millet 0.98%, amaranth 0.19%). Based on the results, puffed proso millet grains had the highest amounts of phenolic compounds and starch, and the lowest amount of crude dietary fibre and fat. Furthermore, both products were the sources of micro-and macrocomponents, primarily potassium, calcium, magnesium, and phosphorus.
