Embodiment 1

[0009] Extraction method of raspberry seed oil at room temperature

[0010] The raspberry seed powder after being crushed to a certain fineness (about 100 mesh) is dried to constant weight. Take 1 kg of seeds, add a solvent according to the ratio of material to liquid 1:10, extract the oil at normal temperature, and then distill the collected liquid to separate the solvent to obtain raspberry seed oil.

Embodiment 2

[0012] Cold Extraction Method of Raspberry Seed Oil

[0013] Wash 1 kg of raspberry seeds that meet the raw material requirements in Example 1 and dry them at 30 to 40° C. to remove surface impurities, pulverize them with a pulverizer and sieve them to obtain raspberry seed powder. Extract the oil with a solvent with a solid-to-liquid ratio of 1:10, cold-extract at 4°C for 8 hours, filter and distill to separate the solvent, and obtain raspberry seed oil, which is stored at low temperature. The purity of raspberry seed oil can reach about 95% through gas chromatography analysis.

Embodiment 3

[0015] Ultrasonic extraction method of raspberry seed oil

[0016] Put the crushed raspberry seed powder in Example 1 into a container, add an extraction solvent at a ratio of 1:10 to the feed liquid, put it into an ultrasonic reactor, adjust different powers, temperatures, and processing times, and take it out for cooling after the extraction is completed. After reaching room temperature, the extracted solution was filtered and stored in a container, and the raspberry seed oil was obtained after vacuum distillation.

Abstract

The invention relates to a plant seed oil product and a method for extracting the same, in particular to a red raspberry seed oil product and a method for extracting the same. The red raspberry seed oil is the plant fat product extracting from seeds of red raspberry fruits, thereby having extremely high nutritive value and better health care function, solving the problem of utilizing the seed separated when the product such as fruit juice and fruit jam is prepared by the red raspberry, changing waste into valuable and having great significance for the development of the red raspberry industry and the comprehensive utilization of byproducts. The extraction and preparation method for the red raspberry seed oil is as follows: seeds separated by pulping the red raspberry fruit is dried, crushed by a crusher and soaked in a solvent with a certain ratio for extraction, by the cooling or ultrasonic auxiliary extraction, the working efficiency and the oil yield are improved, and the seed soaked in the solvent is filtered to separate the solvent and then packaged to obtain the red raspberry seed oil product.

Description

technical field [0001] The invention relates to a plant seed oil product and an extraction method thereof, namely a red raspberry seed oil product (hereinafter referred to as raspberry seed oil) and an extraction method thereof. Background technique [0002] In the prior art, red raspberry seeds are not effectively developed and utilized as a by-product of raspberry in the processing of fruit juice, jam, etc., resulting in waste of resources and high product costs. It is reported that the oil content of red raspberry seeds reaches about 14.6% to 18%, of which 0.73% to 1.10% are phytosterols, linoleic acid, α-linoleic acid, oleic acid and stearic acid. The main component of seed oil. In addition, because the vitamin E content in raspberry seed oil is higher than that in sunflower oil and grape seed oil, raspberry seed oil has high stability. At present, for the product that uses raspberry seed oil as edible or health-care oil, no production and report have been found so far...
