Method for preparing ink by adopting vegetable gelatin to replace animal gelatin

Abstract

The invention discloses a method for preparing ink by adopting vegetable gelatin to replace animal gelatin, comprising the following steps: uniformly mixing the vegetable gelatin with a moderate amount of water, mixing and heating to 70-80 DEG C, preserving heat for 1-3 hours, adding other raw materials except for coconut shell charcoal antibacterial powder, using a three-roll grinder to grind 3-5 times, adding the coconut shell charcoal antibacterial powder and a moderate amount of boiling water, and mixing uniformly to obtain the product. According to the method disclosed by the invention, as the vegetable gelatin is adopted to replace the animal gelatin, risks caused by diseases of animals itself are avoided fundamentally, defects of preservative residues, animal pharmaceutical residues, heavy metal residues and the like of the animal gelatin are overcome. As the coconut shell charcoal antibacterial powder is adopted as preservative, the ink prepared by the preparation method disclosed by the invention has the advantages of naturalness, no harm, long-lasting effect and good stability.

Description

Technical field [0001] The invention relates to the field of ink, and to be precise, a method for preparing ink by using vegetable glue instead of animal glue. Background technique [0002] Generally speaking, ink refers to black liquid or solid. The Chinese seem to have a preference for black.

Problems solved by technology

[0003] Gelatin is one of the most important and indispensable materials for making rice paper ink. Currently, almost all gelatin used in ink making on the market is made from animal skin and bones. On the one hand, gelatin made from animal skin and bone causes a large number of animals to be killed. Hunting, on the other hand, because the main component of animal gelatin contains protein, it will be decomposed and oxidized by microorganisms to hydrogen sulfide (carcinogen) after a long time, and it is easy to deteriorate and smell, which will affect the effect of ink color
