Hydraulic cold pressing method of fructus trichosanthis seed oil

Abstract

The invention discloses a hydraulic cold pressing method of fructus trichosanthis seed oil. The hydraulic cold pressing method comprises the following steps: (a) sorting, washing and draining fructus trichosanthis seeds; (b) drying the drained fructus trichosanthis seeds, and controlling the mass percentage of moisture of the fructus trichosanthis seeds to be 5 percent to 7 percent; (c) taking the dried fructus trichosanthis seeds and putting into a charging barrel of a hydraulic cold pressing machine; separating by an iron plate and uniformly layering; pressing to obtain fructus trichosanthis crude oil; (d) centrifuging and removing impurities of the fructus trichosanthis crude oil to obtain finished-product oil, wherein in the step (c), the pressing temperature is controlled to be 50 DEG C to 60 DEG C, the pressing pressure is 30MPa to 50MPa and the pressing time is 40min to 50min. According to the hydraulic cold pressing method of the fructus trichosanthis seed oil, disclosed by the invention, the fructus trichosanthis seeds are directly utilized and oil is extracted through a hydraulic cold pressing manner, so that the oil yield can be greatly improved, and edible oil sanitary standards can be reached through simple filtering without removing shells and refining.

Description

technical field [0001] The invention relates to a processing method of edible oil, in particular to a hydraulic cold pressing method of Trichosanthes seed oil. Background technique [0002] Trichosanthes, also known as Diaogua, Gualou, and Yaogua, belongs to the Cucurbitaceae Trichosanthes genus herbaceous perennials, and is a traditional Chinese medicinal material commonly used in my country. There are more than 70 species of Trichosanthes in the world, and more than 40 species in my country. Trichosanthes has strong adaptability and is widely distributed in my country, mainly in Shandong, Anhui, Henan, Jiangsu and other places; among them, the coastal areas of Jiangsu have extensive wild resources and have been widely promoted and planted. Trichosanthes seeds are the seeds of the dried ripe fruit of Cucurbitaceae Trichosantheskirilowii Maxim or Trichosanthesrosthornii Harms. The oil content in Trichosanthes seeds is 32.15%, and the content of unsaturated fatty acids is 8...

AI Technical Summary

Problems solved by technology

[0004] 1. Generally, the seeds of Trichosanthes need to be shelled before pressing, but the shells of Trichosanthes seeds are hard and difficult to remove, and there are few professional shellers suitable for Trichosanthes seeds, and some shellers are too large , not suitable for small-scale melon seeds shelling processing

[0005] 2. In Zha Xiaozhu’s patent, the relevant parameters in the pressing of Trichosanthes seed oil are not formulated or the range is too large, which cannot ensure good quality control and high oil yield.

[0006] 3. Edible oil generally needs to be refined, and a large amount of solvent is used in this process, and the temperature is high, which will cause certain damage to the nutrients in the oil
