Problems solved by technology

Among them, the extraction rate of the mechanical pressing method is low, only about 8%. The extraction time of the ultrasonic assisted extraction method is short, and the quality of the oil is better, but the oil yield is low; the supercritical extraction method has a high oil yield and good quality, but Not suitable for large-scale production; therefore, there is an urgent need to find new extraction methods for apple seed oil

Embodiment 1

[0020] A preparation method of apple seed essential oil, comprising the following steps:

[0021] 1) Crush the apple seeds to remove impurities and shells, pass through a 60-mesh sieve to obtain apple seed kernel powder, and then press the apple seed kernel powder hydraulically to obtain crude oil;

[0022] 2) After heating the crude oil to 80°C, dropwise add sodium hydroxide solution with a mass concentration of 21% to the crude oil under stirring, and continue stirring for 30 minutes after the completion of the dripping to complete the alkali refining of the crude oil, and then heat it in a water bath to 95°C Stand at a constant temperature to precipitate the saponified matter and filter to obtain an oil phase. The oil phase is washed with water at a temperature higher than the oil phase until it becomes neutral. Finally, the neutral oil phase washed with water is dehydrated in a vacuum at 90 ° C to obtain a dehydrated oil phase. The dehydrated oil was added with clay and ac...

[0025] A preparation method of apple seed essential oil, comprising the following steps:

[0026] 1) Crush the apple seeds to remove impurities and shells, pass through a 60-mesh sieve to obtain apple seed kernel powder, and then press the apple seed kernel powder hydraulically to obtain crude oil;

[0027] 2) After heating the crude oil to 95°C, dropwise add sodium hydroxide solution with a mass concentration of 20% to the crude oil under stirring, continue to stir for 40 minutes after the completion of the dripping to complete the alkali refining of the crude oil, and then heat it in a water bath to 80°C Stand at a constant temperature to precipitate the saponified matter and filter to obtain an oil phase. The oil phase is washed with water at a temperature higher than the oil phase until it becomes neutral. Finally, the neutral oil phase washed with water is dehydrated in a vacuum at 90 ° C to obtain a dehydrated oil phase. The dehydrated oil was added with clay and activat...

Embodiment 3

[0030] A preparation method of apple seed essential oil, comprising the following steps:

[0031] 1) Crush the apple seeds to remove impurities and shells, pass through a 60-mesh sieve to obtain apple seed kernel powder, and then press the apple seed kernel powder hydraulically to obtain crude oil;

[0032] 2) After heating the crude oil to 90°C, dropwise add sodium hydroxide solution with a mass concentration of 21% to the crude oil under stirring, continue to stir for 35 minutes after the dripping is completed to complete the alkali refining of the crude oil, and then heat to 85°C in a water bath Stand at a constant temperature to precipitate the saponified matter and filter to obtain an oil phase. The oil phase is washed with water at a temperature higher than the oil phase until it becomes neutral. Finally, the neutral oil phase washed with water is dehydrated in a vacuum at 90 ° C to obtain a dehydrated oil phase. The dehydrated oil was added with clay and activated carbo...

Abstract

A manufacture method for apple seed essential oil is disclosed and comprises crushing apple seed and shelling, so as to obtain apple seed kernel powder; then performing hydraulic squeezing on the apple seed kernel, so as to obtain crude oil; heating the crude oil, dropwise adding a sodium hydroxide solution into the crude oil with stirring, continuing stirring after dropwise adding is finished, so as to performing sufficient alkali refining on the crude oil; then standing at a constant temperature, and filtering, so as to obtain an oil phase; and washing the oil phase with water to be neutral, and finally performing decoloring and filtering, so as to obtain the apple seed essential oil. The method employs a chemical process for performing alkali refining on apple seeds, the oil yield is up to 12% or more on the basis of guaranteeing the oil quality, and the method is suitable for industrialized production. According to the method, the processes of hydraulic squeezing and refining are employed for obtaining the apple seed essential oil, various nutrients and the flavor of the apple seed oil are kept to a great degree, and also the apple seed essential oil prepared by employing the method possesses unique flavor, no solvent residue and abundant nutrients.

Description

technical field [0001] The invention belongs to the field of food processing, relates to oil extraction from oil-containing materials, and in particular relates to a preparation method of apple seed essential oil. Background technique [0002] As part of apples, apple seeds are usually discarded by people, but a 2007 study showed that apple seeds contain a lot of oil and nutrients, such as fatty acids and minerals necessary for the human body, including calcium, phosphorus, protein, etc. , potassium, iron, fiber, pectin, oleic acid, linoleic acid and alpha-linolenic acid, etc. Studies have found that apple seed oil can not only relieve stomach cramps, prevent diarrhea, lower blood sugar, prevent various cancers, prevent premature aging, prevent and treat acne or other skin diseases, but also nourish hair and promote healthy hair growth. At present, it has been used in oils for cosmetics and pharmaceutical industries, such as soaps, lotions, shampoos, lipsticks, creams and h...
