Abstract

The invention provides a blend edible oil of peony seed oil and rice germ oil and a preparation method of the blend edible oil. The blend edible oil comprises 42-65% of peony seed oil, 33-52% of rice germ oil, 1-4% of tomato extractive and 1-2% of catechin; the preparation method of the blend edible oil comprises the following steps: the preparation of the peony seed oil; the mixing of main materials; the formation of an emulsification system, and finally, the formation of the finished product of clarified blend edible oil, wherein a subcritical extraction technology and a molecular distillation technology are adopted and combined to extract the peony seed oil, so that the operating temperature is low, the heating time is short, the grease oxidation and rancidification caused by high-temperature can be avoided, the separation degree and the yield coefficient of the product are relatively high, and the acid value of the peony seed oil can also be reduced by the molecular distillation; meanwhile, the blend edible oil is reasonable in matching, healthy, and balanced in nutrition, so that blend oil with high stability and low oil fume generation volume can be formed, and health of long-term cooks is maintained.

Description

technical field [0001] The invention relates to the field of edible oil, in particular to a blended edible oil of peony seed oil and rice germ oil and a preparation method thereof. Background technique [0002] The oil yield rate of peony seeds is 27-33%. Peony seed oil is rich in unsaturated fatty acids, of which linoleic acid accounts for 22.19%, linolenic acid accounts for 35.70%, oleic acid accounts for 27.14%, linoleic acid and linolenic acid are Two essential fatty acids that are particularly important to human health. Among them, linoleic acid has the functions of inhibiting cholesterol synthesis and regulating blood pressure; Anti-aging and other effects; oleic acid can prevent coronary heart disease. The methods of extracting peony seed oil generally include physical methods, chemical methods and supercritical CO 2 Extraction method, supercritical CO 2 The extraction method is mainly used to extract some high value-added products due to high equipment design and ...
