 Quality identification:

1. Shape: oblong--not round--but not thin.

2. Color: red or purplish red except for petals.

3. Petal area: obviously white. If artificial color has been added, the areas where the petals are will be tinted. Artificial coloring is a sign that the seed is of lower quality. Artificial coloring can be toxic.

4. Dryness: the water content should be about 12% to 13%. The seeds should not lump together. Test for dryness by  squeezing them together and then releasing pressure.  Good quality seeds should not lump together; they should become loose when the pressure is released.

5. Taste: sweet. The seeds should not taste acrid.

6. Smell: the smell is fragrant once the package is opened.

7. Sinking test: When dropped into water, the seeds should  float for sometimes and should not sink in a short time.

National Quality Inspection Agency of China has banned the use of sulfur dioxide to preserve the fruit.
