Embodiment 1

[0020] (1) Precipitating and filtering the raw seabuckthorn fruit juice, and separating the fruit puree from the fruit juice;

[0021] (2) Input the filtered seabuckthorn raw juice into a reaction kettle equipped with adsorbent to adsorb heavy metal lead by ion exchange. The temperature is 20-25°C; the adsorbent is strongly acidic styrene-based cation exchange resin, the matrix: styrene-divinylbenzene copolymer; functional group: sulfonic acid group; styrene-divinylbenzene copolymer: sulfonic acid Acid group = 1:1; strengthen the mass transfer process, improve the exchange rate, adjust the flow rate and flow rate, so that the material can achieve the purpose of reducing the lead content, and the lead content of the heavy metal lead content in the seabuckthorn juice raw material is reduced from 0.7 to 1.2 by using an adsorbent. ppm, reduced to below 0.3ppm, the loss of Vc, the main nutrient in seabuckthorn juice, is less than 3%.

Abstract

The invention relates to a deleading processing technology, in particular to a method to reduce and remove the heavy metal lead content in the sea buckthorn juice raw material by ion exchange method, comprising the following steps: firstly, step of filtering sea buckthorn raw juice; secondly, step of absorbing and removing the lead; thirdly, step of high temperature sterilizing. Compared with the prior art, the invention has the advantages of utilizing ion exchange technology, adopting the adsorbent to reduce and remove the lead in the sea buckthorn juice raw material, effectively reducing the lead content in the sea buckthorn raw juice, keeping the loss rate of Vc which is the main nutritional ingredient in the sea buckthorn raw juice below 3%, maintaining unchanged main nutritional ingredients in the sea buckthorn raw juice, having cool, fresh and soft taste and repeatedly usage of the adsorbent after elution regeneration. The invention is suitable for the reduction and removal of the heavy metal lead content in the sea buckthorn juice raw material.

Description

technical field [0001] The invention relates to a treatment technology for removing lead, in particular to a method for reducing the content of heavy metal lead in seabuckthorn juice raw materials by using an ion exchange method. Background technique [0002] At present, domestic seabuckthorn raw materials generally adopt technologies such as alcohol extraction and material removal of lead, but these technologies are not ideal for reducing the lead metal content in seabuckthorn raw materials. The ion exchange process is a reversible chemical reaction between ions in the liquid phase and ions in the solid phase. This method is widely used in component separation and ion removal. This method is also used in the lead removal technology of products at home and abroad, but the application of the lead removal technology in fruit juice, especially the application of the lead removal technology in seabuckthorn juice raw materials has not been reported. ...
