Embodiment 1

[0021] A. The aloe vera leaves are washed, juiced, and sterilized to prepare aloe pulp;

[0022] B. According to the amount of 50ml / t aloe juice, add pectinase to the aloe juice obtained in step A, carry out enzymatic hydrolysis at 50℃ for 60 minutes, then add diatomaceous earth at 0.15% of the mass of aloe vera, stir and mix well After filtering, the filtrate is subjected to high temperature instantaneous sterilization (UHT), and then cooled to below 30°C to obtain aloe juice with a soluble solid content of 0.5%;

[0023] C. According to the volume ratio of aloe juice: macroporous adsorption exchange resin = 25:1, pass the aloe juice obtained in step B through a commercially available food industry macroporous adsorption exchange resin column, and control the contact time for 15 minutes to obtain lead-removed aloe juice ;

[0024] D. The lead-removed aloe juice obtained in step C is conventionally concentrated, sterilized, and dried to obtain aloe whole leaf dry powder with a lead ...

Embodiment 2

[0028] A. The aloe vera is cleaned, peeled, juiced, and sterilized to prepare aloe slurry;

[0029] B. According to the amount of 80ml / t aloe vera juice, add pectinase to the aloe juice obtained in step A, carry out enzymatic hydrolysis at 52℃ for 50 minutes, then add diatomaceous earth according to 0.2% of the aloe vera pulp mass, stir and mix well After filtering, the filtrate is subjected to high temperature instantaneous sterilization (UHT), and then cooled to below 30°C to obtain 16.8 tons of aloe juice with a soluble solid content of 0.75%;

[0030] C. According to the volume ratio of aloe juice: macroporous adsorption exchange resin = 20:1, pass the aloe juice obtained in step B through a commercially available food industry macroporous adsorption exchange resin column, and control the contact time for 20 minutes to obtain lead-removed aloe juice ;

[0031] D. Perform conventional concentration and drying of the aloe juice obtained in step C to remove lead to obtain aloe gel ...

Embodiment 3

[0035] A. The aloe vera is washed, squeezed and sterilized to prepare aloe slurry;

[0036] B. According to the amount of 100ml / t aloe vera juice, add pectinase to the aloe juice obtained in step A, carry out enzymatic hydrolysis at 55°C for 40 minutes, then add diatomaceous earth at 0.1% of the mass of aloe vera slurry, stir and mix well After filtering, the filtrate is subjected to high temperature instantaneous sterilization (UHT), and then cooled to below 30°C to obtain aloe juice with a soluble solid content of 2.0%;

[0037] C. According to the volume ratio of aloe juice: macroporous adsorption exchange resin = 22:1, pass the aloe juice obtained in step B through a commercially available food industry macroporous adsorption exchange resin column, and control the contact time for 10 minutes to obtain lead-removed aloe juice ;

[0038] D. The lead-removed aloe juice obtained in step C is subjected to conventional sterilization and drying to obtain a dry powder with a lead conten...

Abstract

The invention provides a method for removing lead from aloe. The method comprises the steps of squeezing the aloe raw material to obtain juice, filtering the juice and sterilizing the filtrate to obtain aloe normal juice, subjecting the aloe normal juice to ion-exchange adsorption for removing lead, concentrating the obtained product, and subjecting the concentrated product to normal process to obtain dried aloe powder. The method provided in the invention is easy to operate, the lead removing effect is good, and the dried aloe powder in which lead is removed has the lead content of less than 0.3 mg / kg. Employed resin can be recycled so that the environmental pollution is decreased, and the production cost is reduced. Ion exchange resin has specificity, the contact time is short, polysaccarides and functional components are not lost, and diatomite has effective adsorption function, therefore, turbid substances in the aloe slurry is effectively removed, and the obtained aloe product is pure. The method for removing lead from aloe has very good economic and social benefits.

Description

Technical field [0001] The invention relates to a method for removing lead in aloe, belonging to the technical field of plant processing. Background technique [0002] Aloe is an evergreen plant of the Liliaceae and Aloe genus. It is native to the Mediterranean coast and the tropical regions of Africa and America. It is also distributed in Yunnan, my country. Aloe is an ancient, traditional and commonly used Chinese medicine. Whether in traditional medicine or modern medicine, the medicinal value of aloe is affirmed. This is clearly recorded in my country's early medical books and modern pharmacopoeia. In recent years, aloe has been widely used in cosmetics, food, health products and other fields. Although my country's in-depth research, application and industrialization development of aloe vera is not as good as that of developed countries, it has made great progress in recent years, especially in aloe vera food and health products. With the further development of aloe food, a...
