Product Description

The wolfberry is harvested when the fruit is orange red. After drying to the skin wrinkles, it is exposured to the skin moist and soft fruit, then removed the stem.  Wolfberry is a kind of rare traditional Chinese medicine which is very rich in nutrients and has high medicinal value The materials contain not only such as iron, phosphorus, calcium, but also a lot of sugar, fat and protein. It also contains polysaccharide with good health care function to human body and organic germanium that is beneficial to human’s intelligence.

Function

2. With the function of lipid-lowering and anti-fatty liver;

3. Promoting the function of hematopoietic;

4. With the function of anti-tumor and anti-aging.

Applications:

1. Applied in food field, it can be produced into wine, canned, condensed juice and other more nourishment;

2. Applied in health product field , it can be made into suppositories, lotions, injection, tablets, capsules and other dosage forms to regulate immunity;

3. Applied in pharmaceutical field, effectively treating cancer, hypertension, cirrhosis and other diseases;

4. Applied in cosmetics field, it can prevent skin aging and improve skin elasticity.

Condensation reactions are the means by which monomers are put together to form polymers. This process also produces water. For example, two glucose molecules (monomers) form maltose through a condensation reaction. Splitting maltose back into two glucose molecules (monomers) uses water and is called hydrolysis.

Iodine and Starch Experiment | Iodine Experiment | Starch Experiment | Science experiments for kids

Simple and easy experiment to demonstrate the iodine with starch reaction!

For this test you will need:
• Two test tubes
• Soluble starch powder
• Iodine solution
• Water
• Dropper
Procedure:
• Put some starch powder into a test tube and fill the test tube with water.
• Mix the starch in the test tube well until the starch dissolves in the water.
• Fill the other test tube with normal water.
• Place both the test tubes in a test tube stand.
• Using a dropper take iodine solution.
• Put some drops in each test tube.
• Observe that the test tube with starch solution turns to purple black color.
• The other test tube with normal water retains the color of iodine i.e orange or yellow.
Explanation:
Starch is a mixture of amylose and amylopectin, which are different forms of glucose/starch.
Amylose in starch is responsible for the formation of a deep blue black color.
Amylase is long polymer chains of glucose units connected by an alpha acetal linkage and looks much like a coiled spring.
However iodine is a potassium iodide reagent and it is not very soluble in water.
So, iodine is prepared by dissolving it in water in an aqueous solution of potassium iodide. This results in a linear tri-iodide ion (I3−) complex in iodine which is soluble.
This tri-iodide ion (I3−) slips into the coil of the starch causing an intense or deep blue-black color.
