Description
Technical field
The invention belongs to food colloid field, especially a kind of extracting method of sunflower pectin.
Background technology
Pectin is a kind of labyrinth polysaccharide being widely present in terrestrial plant cell membrane.In bakery, acid breast
In the food processings such as beverage, fruit juice, pectin has the effects such as gelling, stable and thickening as hydrophilic colloid.Meanwhile pectin is
Natural water-soluble dietary fiber, there is regulation human body intestinal canal microenvironment, reduce the beneficial functionals such as blood fat.
After industrial pectin extraction method is mainly acidity extraction at present, then with ethanol precipitation, that is, utilize sour hydrolyzed cellular
Wall discharges pectin, realizes the separation of pectin and other materials using characteristic of the pectin insoluble in alcohol afterwards.Wherein, in acidity extraction
Be commonly incorporated into the chelating agent assisted extraction such as disodium ethylene diamine tetraacetate, phosphate, ammonium oxalate, but can improve pectin post processing cost and
Cause security risk；Ethanol precipitation process need to expend a large amount of ethanol, cause to reclaim the problems such as energy consumption is big, environment protection treating cost is high.
The content of the invention
For above-mentioned deficiency, the present invention is intended to provide a kind of be easy to industrialization, the extraction of safe and simple sunflower pectin
Method, this method while high extraction and high purity product is obtained, improve product peace using sodium citrate extraction pectin
Quan Xing, production cost is reduced, eliminate environmental issue.
To achieve these goals, technical scheme provided by the invention is such：A kind of extraction side of sunflower pectin
Method, comprise the following steps：
Step 1：Sunflower dry pan after crushing is subjected to immersion rinsing, control temperature separation of solid and liquid, collects filter at 25 DEG C
Cake；
Step 2：Step 1 gained filter cake is dispersed in water, and adds sodium citrate, stirring, filtering, takes filtrate；
Step 3：Filtrate is heated to 85~95 DEG C, is kept for 30~60 minutes, obtains pectin solution；
Step 4：Pectin solution is spray-dried, obtains jelly powder.
Wherein, the solid-liquid ratio described in step 1 is 5~10：5~40.
Wherein, the dosage of sodium citrate described in step 2 is the 0.5~0.8% of water weight.
Wherein, the pH of system described in step 2 is 2.2~3.8.
Wherein, the mixing speed described in step 2 is 130r/min, and mixing time is 2~3h.
Wherein, the EAT being spray-dried described in step 4 is 180~200 DEG C, and leaving air temp is 60~80 DEG C, flow velocity
For 10~20mL/min.
Wherein, the particle diameter of the jelly powder described in step 4 is 5~10 μm.
Compared with the prior art, production technology of the invention is easy, and cost is low, the pectin of production method of the invention extraction
Impurity removes thoroughly, and product quality is high, and drying time is short, and products obtained therefrom color and luster is good, and particle diameter distribution is uniform, and dissolubility is good.Pectin
Purity reaches more than 99%.
