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.

花色苷液泡包涵体可能具备蛋白质基质，既无膜包裹又无内部结构，其形成是转运进液泡的花色苷与蛋白质基质结合的结果；液泡里的花色苷液泡包涵体形状不规则，象果冻；在花色苷液泡包涵体中，花色苷可能通过氢键连接于蛋白质基质的一个有限空间位点；花色苷液泡包涵体被认为是液泡中花色苷的&陷阱&，优先摄取花色素3，5-二糖苷或酰化的花色苷；花色苷液泡包涵体的存在可增加液泡色彩的强度并导致&蓝化&。

Human beings exccssively artificialize and symbolize the world through limitless inspirations and imaginations, which makes people deeply indulged in the false images created by ourselves. The structure and characteristics of these false images reversely change everything that human beings and the society rely on. Consequently, questions and perplexity on meanings and values of the society are raised by human beings due to those false images.

在想像世界的无限激发上，人类过度地人工化与符号化这个世界，这不但使得人类深陷於由其本身所制造的虚假意象里，也因为这些虚假意象的结构与特质，反身过来改变了人类与社会生活的一切性质，也进而成为人类对於这个社会在意义与价值之间的质疑与茫然，我们竟无法去依存眼前所见的事实。
