Food processors are more appropriate for solid foods, which cannot be effectively ground with a food mill, such as cheese or nuts. The food ground in a food mill must be soft, often being steamed, baked, or boiled before being processed.
Silica (silicon dioxide) is a compound of silicon and oxygen (Si02). It is a hard, glassy mineral substance which occurs in a variety of forms such as sand, quartz, sandstone, and granite.It is also found in the skeletal parts of various animals and plants.ilica (silicon dioxide) is a compound of silicon and oxygen (Si02).

Silica gel is a granular, vitreous, porous form of silicon dioxide made synthetically from sodium silicate.Silica gel is tough and hard; it is more solid than common household gels like gelatin or agar. It is a naturally occurring mineral that is purified and processed into either granular or beaded form.n this form, it is used as a desiccant to control local humidity to avoid spoilage or degradation of some goods. Because silica gel can have added chemical indicators (see below) and adsorbs moisture very well, silica gel packets usually bear warnings for the user not to eat the contents.
