Nutritional and functional characterization of different oat (Avena sativa L.) cultivars

Abstract

Oats are increasingly recognized as super food owing to the presence of multiple health promoting substances. Five indigenous oat cultivars S2000, PD2LV65, SGD2011, Avon and SGD81 were characterized physico-chemically and nutritonally. Avon showed the maximum (12.69 g100 g-1 dry solids) protein content indicating potential to be used as protein source for animal and human food, whereas SGD-81 excelled incrude fiber contents (17.83 g100 g-1 dry solids). Avon showed the highest fat contents (6.67 g100 g-1 dry solids). Maximum moisture contents showed by the SGD-81 (9.29 g100 g-1 dry solids). SGD-2011 showed maximum ash contents (6.02 g100 g-1 dry solids). S-2000 showed the maximum nitrogen-free extract (60.78 g100 g-1 dry solids) and thousand grain weight (36.74 g). Highest Zn (0.176 mg g-1 of dry solids) and Fe (0.032 mg/g-1 dry solids) contents were found in Avon. Avon showed maxium bulk density of 0.76 g/cc and Avon grains had maximum length and breadth ratio (2.93). The highest water absorption capacity, oil absorption capacity and emulsion stability were shown by SGD-81 as 188.33%, 218.754% and 73.13%, respectively. The highest foaming capacity was shown by S-2000 (20%) and the highest emulsion activity was shown by SGD 2011 (56.84%). Amino acid profiling showed the highest outcome 105.67 g kg −1 of dry solids by SGD-2011.While least 99.13 g kg −1 of dry solids depicted by S2000. Total phenolic contents varied from 36.07 to 59.6 mg of gallic acid equivalent (GAE), total flavonoids (754.16-1056.66 mg of quercetin equivalent:QE), TfoC (663.75-697.5 mg QE), % scavenging activity (24.33-55.88%) and anthocyanin contents of 0.5-2.87 mg of C3 G kg −1. SGD-81 was loaded with promising nutraceutical potential. SGD-81 would be good substitute of fiber and also loaded with other promising functional attributes including total flavonoid contents, total phenolic contents, total flavonol conetnts and anthocyanin contents. There is great potential for value addition of the oat cultivar SGD-81.

Investigation of Protein and Epitope Characteristics of Oats and Its Implications for Celiac Disease

“…Meanwhile, oats started to be recognized as a healthy and nutritious cereal, containing a high concentration of soluble fiber (β-glucan) and being dense in nutrients. It has physiological benefits like reducing hyperglycemia, hyperinsulinemia, and hypercholesterolemia, and several other benefits are discussed in several reviews like the one by Ibrahim et al ( 61 ).…”

“…However, the application of size-related analytical techniques like SE-HPLC has a large potential to be used in selecting oat lines for industrial ingredient use ( 61 ).…”

Profiling and characterization of oat cultivars (Avena sativa L.) with respect to bioactive compounds, pesticide residues and mycotoxin

“…By using different strengths of quercetin solution, standard curve was prepared and expressed as quercetin equivalent as showed in results of TFoC. Total flavonoids of the fiber samples were determined as per described method of Ibrahim et al [2] Standard curve was obtained using different concentrations of quercetin solution and expressed as mg quercetin equivalent.…”

“…By procedure described by Ibrahim et al, [2] total flavonol content (TFoC) of fiber samples were determined. Briefly, 0.5 mL of the fiber, 0.5 mL of AlCl 3 (20%) and 1.5 mL of CH 3 COONa (10%) were mixed together.…”

“…Oat particularly exhibits significance for its use as a fodder crop in livestock feed. [2] Throughout the world, oat has been cultivated on wide range of soil types as versatile cereal crop. Moreover, it has also been demonstrated by the previous researches that oat exhibits high tolerance to acidic soil up to pH of 4.5 whereas, oat yield significantly improved by cultivation in soil having pH in range of 5.3-5.7.…”
