Embodiment 1
[0022] A kind of preparation method of the citrus dietary fiber with antiallergic effect is carried out according to the following steps:
[0023] (1) Grinding of citrus peels: using citrus peels as raw materials, soaking in clean water, washing, crushing, and setting aside;
[0024] (2) Extraction of dietary fiber: extract the pulverized material by immersing it in a hydrochloric acid solution with a pH value of 1.5, the extraction temperature is 85°C, and the extraction time is 2 hours; after leaching, filter and collect the extract; the extract is vacuum Concentrate to one-third of the original volume; then add an appropriate amount of ethanol until the ethanol concentration in the solution reaches 70% for precipitation, and the precipitate is dried at 60°C until the water content reaches 9%, and then crushed to obtain dietary fiber powder;
[0025] (3) Compounding: 10 grams of tea polyphenols and 10 grams of proanthocyanidins are added to every 100 grams of dietary fiber p...
Embodiment 2
[0027] A kind of preparation method of the citrus dietary fiber with antiallergic effect is carried out according to the following steps:
[0028] (1) Grinding of citrus peels: using citrus peels as raw materials, soaking in clean water, washing, crushing, and setting aside;
[0029] (2) Dietary fiber extraction: Extract the pulverized material by immersing it in a hydrochloric acid solution with a pH value of 2.0, the extraction temperature is 90°C, and the extraction time is 3 hours; after extraction, filter and collect the extract; the extract is vacuum Concentrate to one-third of the original volume; then add an appropriate amount of ethanol until the ethanol concentration in the solution reaches 60% for precipitation, and the precipitate is dried at 65°C until the water content reaches 10%, and then crushed to obtain dietary fiber powder;
[0030] (3) Compounding: 15 grams of tea polyphenols are added to every 100 grams of dietary fiber powder for compounding to obtain th...
