Embodiment 1

[0024] (1) after cleaning the torreya seed raw material from which the green bark has been removed, the raw material is dried at 40°C until the moisture content is within the range of 5% to 10%, and the shell is obtained to obtain the torreya seed kernel;

[0025] (2) Heat the torreya seed kernels to 100°C and stir-fry for 40 minutes, so as to enhance the torreya seed and increase the decomposition of polyphenols and phytosterols;

[0026] (3) Pressing the fried torreya kernels while hot at a pressing temperature of 100° C. to obtain crude torreya seed oil;

[0027] (4) The obtained Torreya seed crude oil is precipitated and filtered, and refined to obtain the Torreya seed finished oil. The fatty acid composition in the Torreya seed finished oil is 7.44% for palmitic acid, 3.13% for stearic acid, 35.10% for oleic acid, and Oleic acid 39.75%, linolenic acid 0.49%, cis-11-arachidic acid 0.71%, cis-5, 11-arachidic acid 0.82%, cis-11, 14-arachidic acid 2.33%, auraric acid 9.18 %;...

Embodiment 2

[0030] (1) After the raw material of torreya seed from which the green bark has been removed is cleaned, the raw material is dried at 50°C until the moisture content is within the range of 5% to 10%, and the shell is obtained to obtain the torreya seed kernel;

[0031] (2) Heat the torreya seed kernels to 120°C and stir-fry for 40 minutes to enhance the torreya seed and increase the decomposition and production of polyphenols and phytosterols;

[0032] (3) Pressing the torreya seed kernel after stirring while hot at the pressing temperature of 120° C. to obtain the torreya seed crude oil;

[0033] (4) The obtained Torreya seed crude oil is precipitated and filtered, and refined to obtain the Torreya seed finished oil. The fatty acid composition in the Torreya seed finished oil is palmitic acid accounting for 7.45%, stearic acid 3.14%, oleic acid 35.11%. Oleic acid 39.76%, linolenic acid 0.50%, cis-11-arachidic acid 0.72%, cis-5, 11-arachidic acid 0.82%, cis-11, 14-arachidic ac...

Embodiment 3

[0036] (1) after cleaning the torreya seed raw material from which the green bark has been removed, the raw material is dried at 45° C. until the moisture content is within the range of 5% to 10%, and the shell is obtained to obtain the torreya seed kernel;

[0037] (2) Heat the torreya seed kernels to 140°C and stir-fry for 30 minutes to enhance the torreya seed and increase the decomposition and production of polyphenols and phytosterols;

[0038] (3) Pressing the fried torreya seed kernels while hot at a pressing temperature of 140° C. to obtain torreya seed crude oil;

[0039](4) The obtained Torreya seed crude oil is precipitated and filtered, and refined to obtain the Torreya seed finished oil. The fatty acid composition in the Torreya seed finished oil is 7.45% for palmitic acid, 3.13% for stearic acid, 35.11% for oleic acid, and Oleic acid 39.76%, linolenic acid 0.49%, cis-11-arachidic acid 0.72%, cis-5, 11-arachidic acid 0.82%, cis-11, 1 arachidic acid 2.33%, auric ac...

Abstract

The invention discloses a method for preparing oil through torreya seed hot pressing and torreya seed oil rich in polyphenol. The method is characterized by comprising the following steps of performing cleaning to remove green peel torreya seed raw materials; performing dehulling to obtain torreya seed kernels; stir-frying the torreya seed kernels; obtaining crude torreya seed oil through an oil preparation process; precipitating and filtering the crude torreya seed oil; performing refining to obtain finished product torreya seed oil. The method provided by the invention has the beneficial effects that the torreya seed hot pressing oil preparation process provided by the invention opens up a novel process of the torreya seed oil preparation technology; the waste of the torreya seed resources is reduced; the added value of the torreya seed resources is favorably improved; the industrialization can be easily realized; the 100 to 200 DEG C steaming and stir-frying temperature is used for oil extraction; the oil yield of the torreya seeds is highest at 180 DEG C, but the content of sterol reaches the peak value when the steaming and stir-frying temperature is 160 DEG C; the taste is good; when the steaming and stir-frying temperature exceeds 160 DEG C, the torreya seeds have the burnt taste. In the oil preparation engineering, the oil yield is high; the obtained torreya seed oil has high tocopherol, polyphenol and phytosterin contents; intense fragrance of the torreya seeds can be realized.

Description

technical field [0001] The invention relates to the technical field of torreya seed oil preparation, in particular to a polyphenol-rich torreya seed oil and its hot pressing oil production process. Background technique [0002] Torreya is an evergreen tree belonging to the gymnosperm plant Taxaceae (Taxaceae). Torreya has 6 species and 2 varieties: 2 species in North America, 1 species in Japan, and 3 species and 2 varieties in China. Among them, Torreya T. grandis is produced in Zhejiang, southern Anhui, northern Fujian, and northeastern Jiangxi are scattered in Guizhou, Jiangsu, and Hunan to the west, with Zhejiang being the most. Torreya torreya seed "Torreya torreya" is one of the unique rare dried fruits in China. It has high nutritional value, unique flavor and medicinal function, and can be used for both medicine and food. But torreya is propagated directly by seed, often can't keep the original character of female parent tree, easily produces variation. The fruit "...
