Hulless barley kernels were sequentially abraded to achieve 4%, 8%, 16%, 24%, 32%, and 40% removal. Abraded fines, kernels, and ground kernels were stored at 35 degrees C and 75% relative humidity for 3 wk. Stored samples were extracted and the levels of oil, free phytosterols, tocopherols (Ts), and
Because of the positive health effects of phytosterols, phytosterol-enriched foods and foods containing elevated levels of natural phytosterols are being developed. Phytosterol contents in cereals are moderate, whereas their levels in the outer layers of the kernels are higher. The phytosterols in
