Method for analyzing nutritional components in peony seed oil

Abstract

The invention discloses a method for analyzing nutritional components in peony seed oil. The method comprises the following steps of preparing of materials, weighing, centrifuging, obtaining of seed oil extracting liquid, measuring of physical and chemical properties, analyzing of nutritional components, and statistic analyzing. The method has the advantages that the peony seeds in four development phases respectively 40d(S1), 60d(S2), 80d(S3) and 95d after flowering are respectively collected, so as to analyze the nutritional components of the seed oil; the analysis result is more comprehensive, and the used methanol, retinol, alpha-tocopherol, gamma-tocopherol and delta-tocopherol can respectively reach HPLC (high performance liquid chromatography) level; the sample separating ability isgreatly improved, the measuring of saponification value, measuring of iodine value and measuring of peroxide value are simultaneously performed with blank experiment for contrasting, the influence tothe results by the environment, used reagents and operation in the analysis process is avoided, the weight of the weighed peony seed oil is respectively accurate to the micrometer in the measuring ofphysical and chemical properties and analysis of nutritional components, and the measured value is more accurate.

Description

technical field [0001] The invention relates to an analysis method, in particular to an analysis method for nutritional components of peony seed oil, and belongs to the technical field of analysis of natural compounds. Background technique [0002] Oil crops are one of the most important food sources for humans, and their oils have high nutritional value. With the development of my country's economy and the continuous improvement of people's living standards, the per capita oil consumption has gradually increased. At present, my country is at a disadvantage in the international trade pattern of vegetable oilseeds. Part of the reason is that the variety of vegetable oilseeds in my country is relatively single, resulting in import and export. With the trade deficit, mining new sources of vegetable oil has become one of the ways to meet domestic consumption demand, which is also in line with the requirements of my country's food safety strategy. [0003] Peony is a perennial he...

Problems solved by technology

[0003] Peony is a perennial herb of the family Paeoniaceae Paeoniae. It has been cultivated in my country for more than 4,000 years. For a long time, the research and application of Paeoniae mainly focused on the ornamental value of flowers and the medicinal value of roots, while the research on the development and utilization of its seeds But it is rarely involved. In the process of ornamental and medicinal cultivation, a large number of peony seeds are produced every year. Except for a small amount for sowing, the rest are hardly used, resulting in a huge waste of resources. If we can accurately analyze peony The nutritive composition of seed oil is of great significance to the comprehensive development and utilization of its processing resources
