Embodiment 1

[0048] (1) fruit selection: select 50 kg of dried betel nuts without rot, disease spots, and insect damage as raw materials, slice, and pick kernels;

[0049] (2) lye soaking: betel nut is used 300L lye, and lye is the sodium carbonate aqueous solution that mass percentage concentration is 6%, contains lecithin 50g in the lye, soaks 24 hours;

[0050] (3) Cleaning: remove the betel nut from the lye, rinse with pure water until neutral, drain or dry the water;

[0051] (4) Mixed solvent extraction: the betel nut drained in step (3) was reflux extracted twice with a mixed solvent (6# solvent oil: ethyl acetate = 9:1, V / V). The amount of mixed solvent for the first reflux extraction is 800L, and the time for reflux extraction is 4 hours; the amount of mixed solvent for the second reflux extraction is 600L, and the time for reflux extraction is 3 hours. After the reflux extraction is completed, after the solvent is removed by filtration, the residual solvent in the betel nut is d...

Embodiment 2

[0054] Other conditions are the same as in Example 1, except that in step (2), lecithin is replaced with soybean lecithin of the same quality.

[0055] Detected by high-performance liquid chromatography (HPLC) external standard method, the content of arecoline in the low alkaloid betel nut obtained in the present embodiment is 0.0068%; Detected by ultraviolet spectrophotometry, the content of arecoline in the obtained betel nut of the present embodiment is 0.0019% %; Detected by gas chromatography-mass spectrometry (GC-MS), 600 pesticide residues in the obtained betel nuts of the present embodiment were not detected; detected by high performance liquid chromatography, various aflatoxins were not detected in the obtained betel nuts of the present embodiment out.

Embodiment 3

[0057] (1) fruit selection: select 50 kg of betel nut fresh fruit without rot, disease spots, and insect damage as raw material, slice, and pick kernels;

[0058] (2) lye soaking: betel nut is used 300L lye, and lye is the sodium bicarbonate aqueous solution that mass percent concentration is 5%, contains glyceryl distearate 50g in the lye, soaks 24 hours;

[0059] (3) Cleaning: remove the betel nut from the lye, rinse with pure water until neutral, and dry the water;

[0060] (4) Mixed solvent extraction: the betel nut drained in step (3) was ultrasonically extracted twice with a mixed solvent (6# solvent oil:ethyl acetate=8:1, V / V). The amount of mixed solvent used for the first ultrasonic extraction was 500L, and the ultrasonic extraction time was 4 hours; the amount of mixed solvent used for the second ultrasonic extraction was 300L, and the ultrasonic extraction time was 4 hours. After the ultrasonic extraction is completed, after the solvent is removed by filtration, th...

Abstract

The invention provides an alkaloid-free/low-alkaloid areca-nut and a preparation method thereof. The alkaloid-free/low-alkaloid areca-nut is obtained by soaking an areca-nut in alkali liquor containing a surfactant, and the content of arecoline in the areca-nut is 0.02 wt% or below. According to the method disclosed by the invention, the alkali liquor is matched with the surfactant, so that arecoline with carcinogenic threat in the areca-nut can be fully leached out, and meanwhile, pigments and pesticide residues are effectively removed, and trace elements beneficial to a human body are reserved, tannin and polyphenol components are not influenced, and the physiological activity and the specific flavor of the areca-nut are still reserved. The method is simple in process, ingenious in design, high in operability, free of pollution, large in raw material handling capacity, low in production cost and suitable for industrial production.

Description

technical field [0001] The invention relates to betel nut products, in particular to an alkaloid-free / low alkaloid areca nut and a preparation method thereof. Background technique [0002] Betel nut, also known as betel nut, big belly, binmen, olive, green boy, betel nut jade, betel nut jade, is an evergreen tree plant betel nut (Areca catechu L.) of ripe fruit. Betel nuts are native to Malaysia and are widely cultivated in tropical Asia. China's betel nut planting is mainly distributed in tropical regions such as Yunnan, Hainan and Taiwan. [0003] Betel nut is an important Chinese herbal medicine. Traditional medicine believes that betel nut has the effects of "killing insects, breaking accumulation, reducing qi and stagnation, promoting water and eliminating dampness". According to medical records, the main functions of betel nut are: "curing diarrhea and dysentery, all pains in trusted subordinates, constipation in defecation, phlegm and shortness of breath. Treating...
