1 Pretreatment of rapeseed Pretreatment includes crushing, steaming and peeling. The purpose of rapeseed peeling is to remove the main fiber and pigment body, otherwise it will reduce the feeding value of the cake. On the other hand, the leaching process is conducive to solvent penetration (the leaching can improve the porosity of the blank).

Since grape seeds are usually discarded as part of the wine making process, the extraction and sale of the oil can be a profitable sideline, as well as an efficient use of a byproduct. In the 20th century, it began to be processed and sold in much

Saturated fat is one of the two main categories of fats that appear in foods. It is distinguished from unsaturated fat in that there are no double bonds between carbon atoms in its chemical makeup, so that the fatty acids are saturated with hydrogen. Naturally occurring saturated fat, such as the fat found in animal-based foods, congeals when cool, while naturally occurring
Palm oil, an oil extracted from the palm nut kernel, is one of the few natural oils to have a high amount of saturated fat when compared to oils such as vegetable and olive oil, which are high in unsaturated fat. Before it is the clear oil available on grocery shelves, it is crude palm oil (CPO). This
