Embodiment 1

[0037] A method for post-ripening Chinese torreya seeds after stacking and retting, carried out according to the following steps:

[0038] (1) Harvesting: Torreya chinensis gradually changes from emerald green to light yellow, longitudinal cracks appear on the surface of Torreya chinensis, and the arils are cracked to expose the seed cores, and the damaged and odorous seeds are removed, and the seeds with the same particle size, well-proportioned, neat and plump are selected. Torreya seeds are used as raw material.

[0039] (2) Remove the arils: remove the arils manually or mechanically from the plucked torreya,

[0040] (3) Stack retting: stack the torreya seeds that have been removed from the arils on the indoor mud floor (there is water on the torreya seeds and need to be dried before stacking), the stacking height is 25cm, and stacked in a cool, ventilated environment around. Shade net, turn it once every 3 days, cover the shade net after turning over, pile up until the s...

Embodiment 2

[0058] A method for post-ripening Chinese torreya seeds after stacking and retting, carried out according to the following steps:

[0059] (1) Harvesting: Torreya is picked when it changes from emerald green to light yellow, longitudinal cracks appear on the surface of Torreya, and the aril cracks to expose the seed core. Remove damaged and odorous seeds, and choose torreya seeds with the same particle size, well-proportioned, neat and plump as raw materials.

[0060] (2) Removing the arils: removing the arils from the picked Torreya chinensis manually or mechanically.

[0061] (3) Stack retting: stack the torreya seeds that have been removed from the arils on the indoor mud floor (there is water on the torreya seeds and need to be dried before stacking), the stacking height is 20cm, and stacked in a cool, ventilated environment around. The shading net is turned once every 5 days, and the shading net is covered after turning. Pile until the seed coat inside the torreya seeds...

Embodiment 3

[0065] A method for post-ripening Chinese torreya seeds after stacking and retting, carried out according to the following steps:

[0066] (1) Harvesting: Torreya is picked when it changes from emerald green to light yellow, longitudinal cracks appear on the surface of Torreya, and the aril cracks to expose the seed core. Remove damaged and odorous seeds, and choose torreya seeds with the same particle size, well-proportioned, neat and plump as raw materials.

[0067] (2) Removing the arils: removing the arils from the picked Torreya chinensis manually or mechanically.

[0068] (3) Stack retting: stack the torreya seeds that have been removed from the arils on the indoor mud floor (there is water on the torreya seeds and need to be dried before stacking), the stacking height is 30cm, and stacked in a cool, ventilated environment around. The shading net is turned once every 5 days, and the shading net is covered after turning. Pile until the seed coat inside the torreya seeds...

Abstract

The invention relates to the technical field of storage and processing of edible forest products and particularly relates to a method for stack retting after-ripening of Chinese torreya seeds. The method comprises picking cracking Chinese torreya, removing aril, stacking the Chinese torreya seeds without aril in a shady, cool and ventilated environment, covering the Chinese torreya seeds with a shading net, wherein the pile height is 20 to 30cm, vertically turning over the Chinese torreya seeds once every 3-5 days, wherein after turning, the Chinese torreya seeds are covered with the shading net, carrying out stack retting for after-ripening, then cleaning the Chinese torreya seeds, airing the Chinese torreya seeds and storing the Chinese torreya seeds in the cool and ventilated position. Through improvement of maturity of the picked Chinese torreya and a one-step stack retting method, an after-ripening process is accelerated, the after-ripening quality the same to that obtained by secondary stack retting is kept, and the problems that the existing stack retting method has long stack retting time and environmental pollution is caused by removed aril are solved.

Description

technical field [0001] The invention relates to the technical field of storage and processing of edible forest products, in particular to a method for shortening the post-ripening time of Chinese torreya seeds and improving post-ripening quality. Background technique [0002] Torreya grandis (Torreya grandis'Merrilli') is an excellent variety of Torreya grandis (Torreya grandis) in the yew family (Taxaceae). 546.2~614.7g / kg), the fatty acid composition is mainly linoleic acid and oleic acid, and unsaturated fatty acid accounts for 79.41% of total fatty acid, has remarkable effect on preventing and treating human cardiovascular and cerebrovascular diseases, and is a treasure in dried fruit. Therefore, the oil content and its unsaturated fatty acid composition are one of the important indicators for evaluating the quality of Torreya torreya seeds. [0003] Picking time and post-ripening treatment had great influence on the oil quality of oilseeds. The fatty acid composition ...
