Problems solved by technology

The extraction method of peony oil is mainly pressing method at present, the yield of peony oil produced by this method is large, which is suitable for industrial production, but in the process of squeezing and extracting peony seed oil, a large amount of cakes will be produced, and there are still residues in these cakes It is a pity that these high-quality vegetable oils are not proposed for reuse, and it also affects the further extraction and application of cakes

Abstract

The invention belongs to the technical field of application of peony meal obtained after peony oil extraction, in particular to a comprehensive utilization method of peony meal. The method provided by the invention comprises the following steps: pretreating peony seed meal, then extracting the peony seed meal by supercritical carbon dioxide, and further extracting paeonol, peony saponin, peony protein and peony polysaccharide from the residue obtained after peony oil extraction, wherein paeonol, peony saponin, peony protein and peony polysaccharide can be used as food material or prepared into feed. The method provided by the invention has the beneficial effects that by adopting the method to process the peony meal, not only can peony oil be extracted from the peony meal, but also paeonol, peony saponin, peony protein and peony polysaccharide can be further extracted from the peony meal to be used as food material or prepared into feed, so that the economic value is improved, and the comprehensive utilization of the peony meal is realized.

Description

technical field [0001] The invention belongs to the technical field of utilization of peony cake after virgin peony oil, and in particular relates to a comprehensive utilization method of peony cake. Background technique [0002] In the main peony producing areas, a large amount of peony seeds can be produced every year. According to incomplete statistics, the annual seed yield of the existing area is about 600,000 kilograms. Peony seeds contain a lot of oil, rich in oleic acid, linoleic acid and linolenic acid, and the content of unsaturated fatty acids is more than 90%. The by-product peony cake after virgin pressing contains a lot of health substances such as peony protein, paeonol saponin, peony polysaccharide, paeonol and so on. The extraction method of peony oil is mainly pressing method at present. The yield of peony oil produced by this method is large, which is suitable for industrial production. However, in the process of extracting peony seed oil by pressing, a ...
