Embodiment Construction

[0013] 1. Drawing the standard curve

[0014] Prepare the dextran standard stock solution, accurately weigh 0.5007g of the dextran reference substance dried to constant weight, add water to dissolve, and dilute to 50ml, mix well, and store in the refrigerator.

[0015] Prepare dextran standard use solution. Take 1.00ml of dextran standard stock solution, place it in a 100ml measuring flask, add water to the mark, mix well, and store in the refrigerator. This solution contains 0.10mg of dextran per 1ml.

[0016] Precisely draw dextran standard solution 0, 0.10, 0.20, 0.40, 0.60, 0.80, 1.00 ml (equivalent to dextran 0, 0.010, 0.020, 0.040, 0.060, 0.080, 0.10 mg) and place them in 25ml colorimetric tubes. Add water to 2.0ml accurately, add 1.0ml of 50g / L phenol solution, and mix on a rotary mixer. Carefully add 10.0ml of concentrated sulfuric acid and carefully mix on the rotary mixer until it boils in a boiling water bath for 2 minutes. After cooling to room temperature, use a spectr...

Abstract

Polysaccharides are non-specific immune enhanced compounds, a phenol-sulfuric acid colorimetric method is used for determining the content of the polysaccharides, the method is stable, and the glucose concentration is suitably controlled at 510-2510 mg/L. A phenol reagent and concentrated sulfuric acid are precisely added, firstly allowed to stand, then shaken, placed in a water bath to heat for 15 min, and then immediately cooled; test results of linear, precision, stability and the like can show that the spectrophotometric method for determination of the crude polysaccharide content in health-care food has high accuracy and good reproducibility, and the method is simple and easy to operate.

Description

Technical field [0001] The invention belongs to the field of food analysis, and specifically relates to a method for detecting functional components of health food. Background technique [0002] Health food is a type of food. It has the common characteristics of general food. It can regulate the functions of the human body. It is suitable for certain people to eat, but it cannot treat diseases. The rise of health (functional) food in my country was in the late 1980s and early 1990s. After the first and second generations of development, it will also enter the third generation. That is, health foods not only require human and animal experiments to prove that the product has certain items For the physiological regulation function, it is more necessary to find out the structure, content, mechanism of action and the stable form of the food with the health function factor. [0003] The functional components of health food mainly include polysaccharides, saponins, flavonoids, enzyme horm...
