Embodiment 1
[0017] 1. Select dry grass jelly leaves that are free from rot and disease, and rinse them with clean water to remove mud, sand and impurities.
[0018] 2. Use a colloid mill to pulverize the washed grass jelly leaves into ultra-fine particles.
[0019] 3. Put the above pretreated materials into a multi-functional extraction tank, add water in a weight ratio of 1:15, gradually heat to boiling, and continuously cook and extract for 1 hour under a steam pressure of 1.5Kpa.
[0020] 4. Centrifuge the extracted stock solution to remove slag, then filter the plate and frame, and import the filtrate into the sedimentation tank.
[0021] 5. Add 1% activated carbon for sugar in the filtrate, and stir at 90°C for 45 minutes to make it evenly mixed. Put the mixed solution into a decanter centrifuge for separation and decolorization, and remove activated carbon and its attachments under the condition that the separation factor is greater than 9000. Repeat this process until the juice i...
Embodiment 2
[0025] Add the washed jelly grass leaves to water at a ratio of 1:10, pulverize them in a colloid mill, boil and extract them continuously for 0.5 hours under a steam pressure of 1Kpa, and filter out the residue. Add 0.5% activated carbon for sugar in the filtrate, stir at 80° C. for 30 minutes, and mix evenly. The mixture is separated and decolorized once in a centrifuge to remove activated carbon and its attachments. The filtrate was spray-dried, the inlet temperature of the spray dryer was controlled at 150°C, and the outlet temperature was controlled at 60°C. The obtained grass jelly polysaccharide gum powder product is light yellow, and becomes light yellow granules after granulation.
example 3
[0027] Add clean water to the washed jelly grass leaves at a ratio of 1:20, pulverize them in a colloid mill, boil and extract them continuously for 1.5 hours under a steam pressure of 2Kpa, filter and discard the residue, and spray-dry the filtrate. The inlet temperature of the spray dryer is controlled at 200°C , the outlet temperature is controlled at 80°C. The obtained grass jelly polysaccharide gum powder product is brown, and after granulation, it is brown granules.
[0028] Add the jelly grass polysaccharide gum particles of different colors prepared in the above example into 100 to 300 times the amount of feed liquid (fruit juice, milk, pudding, etc.), mix with 3 to 5 times the amount of edible starch, stir evenly and heat to 100 After ℃, cool naturally to form transparent or pigmented jelly or gel.
[0029] The jelly polysaccharide gum prepared by the invention has good elasticity, good texture, and chewability, and can be used as a gelling agent for jams, jellies, p...
