Abstract: The cereals of highest consumption in Venezuela are corn, wheat and rice, the later having a higher yield and a better nutritional value that decreases with processing. Brown rice is rich in vitamins and minerals and its consumption is low, due to its long cooking time (45-60min). In recent years there has been a boom in the development of healthy products of fast preparation. The objective was to obtain and evaluate a quick-cooking brown rice. A three-stage process was used: 1) Soaking. The effects of dissolution, temperature and time on the water absorption, volume increase and humidity were evaluated. 2) Cooking. The effects of temperature and time on water absorption, volume increase and gelatinization were studied, and the best treatment was compared with heating in an autoclave. 3) Drying. Two temperatures were used and the rehydration capacity was measured. The composition and mineral content of the raw brown rice and the quick cooking brown rice were determined. A quick cooking (25min) brown rice was obtained which maintained its nutritional characteristics in terms of protein, fiat and minerals.
