Abstract
A method of processing vegetable oil in which non-toxic reagents are used, so that a waste stream is evolved suitable for use as a nutrient source and wherein the non-toxic reagents include nutrient components whereby the nutrient value of the waste stream is enhanced.
Claims5
A method of processing vegetable oil so that waste streams from the process are provided with enhanced usefulness as nutrient sources, comprising the steps of:
- (a) harvesting oil-containing vegetables from a growing area,
- (b) extracting crude vegetable oil from the vegetables,
- (c) forming a soapstock by refining the crude oil with a base, the components of which have low toxicity to plants or animals,
- (d) separating the refined oil from the soapstock,
- (e) treating the resulting soapstock with an acid, the components of which have low toxicity for said plants and animals, to form a mixture of an acid water phase and an acid oil phase,
- (f) separating the resulting acid oil from the resulting acid water phase, and
- (g) utilizing the nutrients contained in said acid oil and or acid water phases.
A method of processing vegetable oils and by-products including the steps of harvesting oil-containing vegetables from a growing area, extracting crude vegetable oil from the vegetables, and forming a soapstock by refining the crude vegetable oil with base;
- separating the refined vegetable oil from the soapstock;
- treating the resulting soapstock with an acid to form a mixture of an acid water aqueous phase and an acid oil;
- separating the resulting acid oil from the resulting acid water aqueous phase;
- characterized by the step of:
- applying the aqueous phase as a fertilizer to soil or growing plants.
