Processing technology of torreya grandis fruits

Abstract

The invention discloses a processing technology of torreya grandis fruits, which comprises the following steps: washing picked fresh torreya grandis fruits, and removing aril to obtain torreya grandis fruits; the preparation method comprises the following steps: washing aril residues on the surfaces of torreya grandis fruits, drying in the air, frying at 130-140 DEG C for 10-15 minutes, and squeezing at 50-60 DEG C for multiple times to obtain squeezed liquid; heating the squeezed liquid to 75-85 DEG C, then stirring and adding a separating agent, uniformly mixing, standing for 2-3 hours, and separating to remove lower-layer precipitate and solution, so as to obtain upper-layer torreya grandis crude oil; heating the torreya grandis crude oil to 70-80 DEG C, then adding a purifying agent, uniformly stirring and mixing, then cooling to 30-35 DEG C, and filtering to obtain the torreya grandis oil. The method overcomes the defects in the prior art, simplifies the processing technology of torreya grandis fruits, does not need high-temperature stir-frying in the processing process, and avoids damage to effective components in kernels.

Description

technical field [0001] The invention relates to the technical field of processing Torreya fruit, in particular to a processing technology of Torreya fruit. Background technique [0002] Torreya is a species of the yew family Torreya, alias Torreya, Torreya, Torreya japonica, Torreya, evergreen coniferous trees, the fruit of Torreya is generally called Torreya. On the outside of the mature Torreya seeds, there is a thick layer of succulent aril, which accounts for about 50%-60% of the fresh weight of the seeds. Some processes for processing Torreya fruits need to further remove the coating and shell outside the Torreya nuts. The processing process is cumbersome, and high temperature frying is required during the processing, so that the oil and active ingredients in the Torreya nuts are destroyed. The processed Torreya oil needs to go through tedious processing steps, the production cost is high, and the quality of the produced Torreya oil is not high. SUMMARY OF THE INVENT...

Problems solved by technology

And there is a very thick succulent aril on the outside of the ripe torreya, which accounts for about 50%-60% of the fresh weight of the seed. After removing the aril, the outside of the torreya kernel is also wrapped with coating and shell, now The technology that some torreya fruit is processed needs to further remove the coating and shell outside the torreya kernel, and the processing process is loaded down with trivial details, and needs high-temperature frying in the processing process, makes the oil and active ingredient etc. in the torreya nut be destroyed, simultaneously The processed torreya oil needs to go through cumbersome processing steps, the production cost is high, and the quality of the produced torreya oil is not high
