Problems solved by technology

The main disadvantages of this method are: one, there are many steps in this method, and the operation is cumbersome; second, this method is very prone to oil oxidation and rancidity in the process of frying and processing Torreya torreya, resulting in rapid frying and finished product quality of Torreya torreya. The falling problem does not come up with an effective solution
But for Chinese torreya, oil oxidative rancidity is the main problem that influences the quality of Chinese torreya finished product in the frying process, and this document does not relate to the problem of oil rancidity and oxidative rancidity in the frying process of Chinese torreya, and this exists with the present invention. Significant differences

Embodiment 1

[0034] A processing method of Torreya torreya, concrete operation steps are:

[0035] (1) Material selection and pretreatment: use mature, well-proportioned, neat and plump Torreya seeds as raw materials, remove damaged and odorous seeds, wash and sun-dry after retting to remove astringency, and obtain raw materials before frying.

[0036] (2) Stir-frying for the first time: pour coarse salt into an iron pan and stir-fry (roast) heat, then mix with the torreya seeds obtained in step (1) and stir-fry together (ratio by weight Torreya seeds:coarse salt=1:0.6), Stir-fry (roast) continuously in the pot, and stir-fry (roast) the seeds at a temperature of 130°C for 10 minutes.

[0037](3) Soak salt: prepare saturated salt water, add weight ratio and be 0.01% TBHQ and stir evenly, the Chinese Torreya seed that step (2) obtains is immersed in the saturated salt water that contains TBHQ of 6 times of volumes, soaks 10 minutes, makes Chinese Torreya seed Take out after fully absorbing ...

Embodiment 2

[0055] A processing method of Torreya torreya, concrete operation steps are:

[0056] (1) Material selection and pretreatment: use mature, well-proportioned, neat and plump Torreya seeds as raw materials, remove damaged and odorous seeds, wash and sun-dry after retting to remove astringency, and obtain raw materials before frying.

[0057] (2) Stir-frying for the first time: pour coarse salt into an iron pan and stir-fry (roast) heat, then mix the torreya seeds obtained in step (1) and fry together (ratio by weight Torreya seeds:coarse salt=1:0.7), And stir-fry (roast) continuously in the pot, stir-fry (roast) the seeds at a temperature of 120°C for 10 minutes, when the shell of the seeds burns hands and the ends of the seeds are slightly yellow, take them out of the pot.

[0058] (3) Soaking salt: prepare saturated salt water, add 0.03% TBHQ (weight ratio) and stir evenly, the Chinese Torreya seed that step (2) obtains is immersed in the saturated salt water that contains TBH...

Embodiment 3

[0064] A processing method of Torreya torreya, concrete operation steps are:

[0065] (1) Material selection and pretreatment: use mature, well-proportioned, neat and plump Torreya seeds as raw materials, remove damaged and odorous seeds, wash and sun-dry after retting to remove astringency, and obtain raw materials before frying.

[0066] (2) Stir-frying for the first time: pour coarse salt into an iron pan and stir-fry (roast) heat, then mix with the torreya seeds obtained in step (1) and stir-fry together (ratio by weight Torreya seeds:coarse salt=1:0.5), Stir-fry (roast) continuously in the pot, and stir-fry (roast) the seeds at a temperature of 140°C for 8 minutes.

[0067] (3) Soak salt: prepare saturated salt water, add 0.03% TBHQ (weight ratio) and stir evenly, the Chinese Torreya seed that step (2) obtains is immersed in the saturated salt water that contains TBHQ of 7 times of volumes, soaks 8 minutes, makes Chinese Torreya seed Take out after fully absorbing the sa...

Abstract

The present invention belongs to the processing field of agricultural and sideline products and particularly relates to a processing method of torreya grandis. The processing method includes that TBHQ is added and used in the frying process of the torreya grandis seeds. The processing method effectively solves the problem of lipid oxidation rancidity during the frying process of the torreya grandis seeds and can improve the quality of the fried products of the torreya grandis.

Description

technical field [0001] The invention belongs to the field of agricultural by-product processing, and in particular relates to a processing method of Chinese torreya. Background technique [0002] Torreya grandis (Torreya grandis 'Merrillii') is an excellent variety of Torreya grandis (Torreya grandis) in the family Taxaceae. Torreya is crispy in flavor and rich in nutrition. It is one of the precious dried fruits in the world. Torreya torreya seed kernel protein content is 12.1~16.4%, has 17 kinds of amino acids, contains 5 kinds of vitamins, and seed kernel oil content reaches about 60%, wherein unsaturated fatty acid reaches more than 80%. Torreya seeds need to go through the process of salt immersion and high temperature frying after harvesting. Due to the rich unsaturated fatty acids, Torreya is prone to oil oxidative rancidity during the frying process, resulting in a rapid decline in the quality of Torreya roasted and finished products. At the same time, harmful pero...
