Embodiment 1

[0029] The preparation of embodiment 1 fresh corn silk extraction concentrate

[0030] 1. Weigh 100kg of Kennian No. 1 corn silk at the milk maturity stage after removing impurities;

[0031] 2. Wash the corn silk with pure water, and then cut it to 5-10mm;

[0032] 3. Preheat the pure water to 90°C and transfer it to the extraction tank, put the cut corn silk into the extraction tank, according to the ratio of fresh corn silk to pure water (kg:L) is 100:1000 in 90 Soak for 1.5 hours at ±2°C;

[0033] 4. Filter the soaking solution to obtain filtrate A;

[0034] 5. Preheat the pure water to 90°C and transfer it to the extraction tank, and soak the corn silk in step 3 twice, according to the ratio of fresh corn silk to pure water (kg:L) of 100:400 at 90°C Soak for 1 hour;

[0035] 6. Filter the second soaking solution to obtain filtrate B, and mix it with filtrate A;

[0036] 7. Concentrate the mixed filtrate 3 times in a double-effect falling film evaporator to obtain a l...

Abstract

The invention provides a corn stigma extraction concentrated liquor made from corn stigmas in a milk-ripe stage and purified water and a preparation method thereof. The total polysaccharides content of the corn stigma extraction concentrated liquor is 2.0-3.5mg / mL, so that the corn stigma extraction concentrated liquor not only can replace drinking water to supplement water, but also can be drunk by users with diuresis, blood sugar decreasing, blood pressure lowering, blood fat reducing and liver and gallbladder protecting requirements for a long time as a daily drink. The preparation method is simple and easy and suitable for industrial production.

Description

technical field [0001] The invention relates to a corn silk extraction concentrate and a preparation method thereof, in particular to a method for preparing the concentrate by using corn silk in milk ripening stage and purified water as raw materials. The invention belongs to the field of health beverage processing. Background technique [0002] Corn silk is the style and stigma of Zeamays L., a grass plant. The earliest medicinal records can be found in "Southern Yunnan Materia Medica" in 1476. The compounds isolated and identified from corn silk mainly include flavonoids and their glycosides, sterols, alkaloids, sugars, organic acids, volatile oils, trace elements and multivitamins. The US FDA regards corn silk and corn silk extract as substances that are generally recognized as safe (GRAS) and can be directly added to food; my country's Ministry of Health "Approval on Issues Concerning Corn Silk" (Health Supervision Letter [2012] No. 306 ): Corn silk has a certain edible ...
