Description of drawings
Fig. 1 is the technological process of production figure of Radix Rhodiolae extract provided by the invention.
Fig. 2 is Radix Rhodiolae and Vc oxidation resistance comparison diagram.
The specific embodiment
The invention will be further described below in conjunction with specific embodiment, but the present invention is not limited to following examples.
The preparation method of embodiment 1, Radix Rhodiolae extract and oxidation resistance are measured
The preparation method of Radix Rhodiolae extract provided by the invention, its technological process of production figure as shown in Figure 1, detailed process is as follows:
1) get the Radix Rhodiolae tuber and smash to pieces, remove the peel, join in the heating container with the solid-liquid ratio of 1:15, heating is stirred, and boils 10 minutes;
2) stop heating, water cycle is cooled to 50 ℃, and with 200 order gauze coarse filtration, 5000r/min centrifugal 10 minutes, gets supernatant;
3) sucking filtration is measured pH value, solid content and electrical conductivity, to determine whether sucking filtration liquid meets product index; Measurement result is: pH value is that 5-7, solid content are that 2.5%-3.5% and electrical conductivity are 500-800 μ s/cm
2
Add the pure glycerin of sucking filtration liquid quality 20% and the trehalose powder of sucking filtration liquid quality 3% afterwards; Measure pH value, solid content and electrical conductivity, to determine whether finished product meets product index; Measurement result is: pH value is that 5-7, solid content are that 24-28% and electrical conductivity are 300-700 μ s/cm
2
4) 95 ℃ are incubated 30 minutes, and water-bath is cooled to 50 ℃, add the 0.6%LGP liquid preservative, this antiseptic full name is LIQUID GERMALL PLUS, available from the international special product company limited of ISP, obtains Radix Rhodiolae extract provided by the invention, purity is 85%, and extraction ratio is 81%.Afterwards as required, can carry out subsequent operation, as cask washing, sterilization, fill, vanning, beat the sign indicating number, the warehouse-in.
Utilize the DPPH method to measure the oxidation resistance of this Radix Rhodiolae extract.This DPPH method is carried out according to the method that following document provides: Zheng Dagui, and Ye Qing, Ye Hongde, surplus redundancy due to misprinting, the DPPH method is estimated the antioxygenic property of Vc, different Vc and derivant thereof, food industry science and technology, 2008 the 04th phase: 113-115.
1) taking by weighing 20mgDPPH, is the dissolving of 95% ethanol water with mass percent concentration, and in the 250mL volumetric flask standardize solution, making the final concentration behind the DPPH standardize solution is 2 * 10
-4Mol/L;
2) get isopyknic liquid to be measured and 2 * 10
-4The DPPH solution of mol/L mixes and mixing, is numbered A
2Pipe; Wherein, liquid to be measured is to be diluted to mass percent concentration to be respectively 2%, 1%, 0.5%, 0.25% Radix Rhodiolae extract aqueous solution and Vc aqueous solution.Because the antioxygenic property of Vc is very good, general positive control as antioxidant.By can intuitively reflecting the antioxygenic property of this material with the comparison of Vc antioxygenic property.Used Vc is available from the Beijing Chemical Plant.
