El arroz cocinado con aceite de coco tiene - 50% calorias

Aumentando el porcentaje de hidratos que no se absorben

developing a new way of cooking rice that increased the RS content. In this method, they added a teaspoon of coconut oil to boiling water. Then, they added a half a cup of rice. They simmered this for 40 minutes, but one could boil it for 20-25 minutes instead, the researchers note. Then, they refrigerated it for 12 hours. This procedure increased the RS by 10 times for traditional, non-fortified rice.

How can such a simple change in cooking result in a lower-calorie food? James explains that the oil enters the starch granules during cooking, changing its architecture so that it becomes resistant to the action of digestive enzymes. This means that fewer calories ultimately get absorbed into the body. “The cooling is essential because amylose, the soluble part of the starch, leaves the granules during gelatinization,” explains James. “Cooling for 12 hours will lead to formation of hydrogen bonds between the amylose molecules outside the rice grains which also turns it into a resistant starch.”

Muy interesante, pero ¿No se oxidará la grasa del coco al cocerla tanto tiempo?

In general, the less refined the oil, the lower the smoke point. Unrefined oils high in PUFAs have the lowest smoking points (link), but high saturated fatty acid content does not necessarily guarantee a high smoking point. Coconut oil, for example, has a fairly low smoking point (177 °C, about the same as butter and lard) compared to peanut oil (227 °C). Refined avocado oil, which is mostly monounsaturated fat, appears to have one of the highest smoking points at 255-270 °C (link). Ghee is another oil with a very high smoking point (252 °C).

El agua cuece a 100 c, no creo que llegara a oxidarse demasiado, aunque ahí quizás un tecnologo o un quimico sabría precisar mejor.

Fisio ¿Crees que también funcionaria con las patatas?
