The conclusion was drawn by the synthesis of molecular sieve: after mixed soluble glass and aluminium sulfate with proper proportion under room temperature, it was stirred stormily to react. And then we mixed with potassium hydroxide solution after filtrating. At last, the molecular sieves of potassium type was synthesized after the mixture reacted in the oven or autoclave for 24 hours. The molecular sieve was remodeled more than twice with ammonium chloride solution that the concentration was 3mol/L and then remodeled twice with the saturated sodium chloride solution. Finally the molecular sieve was changed into the sodium type. It was named W zeolite.

AVI may be protein matrix and it possesses neither a membrane boundary nor an internal structure,its formation is the result of the anthocyanins transported into the vacuole bind with a protein matrix. In vacuole, AVI is irregular and jelly-like in shape. In AVIs, the attachment of anthocyanins to the matrix protein is likely to be via H-bonds to a sterically restricted site. AVI is suggested to act as vacuolar anthocyanin "trap", preferentially for anthocyanidin 3, 5-diglycosides or acylted anthocyanins. The emergence of AVI can enhance color intensity and results in the "blueness" of color in the vacuole.
