Description
Technical field
The present invention relates to ink areas, specifically, being related to a kind of edible water-based ink.
Background technique
Currently, water-based ink has lower VOCs discharge amount because using water as solvent, compared with oil-based ink, protected in environment
Absolute advantage is all shown in terms of shield and bio-safety.And the ink directly contacted with food is in addition to having Water-borne modification feature
Outside, it is necessary to have the requirement of food-grade.
The water-based ink that the current overwhelming majority has food-grade focuses in the selection of ink component, actively seeks
Meet the other raw material of food-grade.Reach the requirement that final finished has food-grade.Also patent selection uses edible material
To prepare edible ink.In the pigment use aspect of ink, there is patent to use the encapsulated by structures pigment of microcapsules, pigment is made to exist
Effectively disperse in aqueous color paste.Since food-grade ink meets food rank only for the ink that food directly contacts,
But still cannot illustrate is edible ink.Especially protrusion may connect for a long time in disposable service plate, food packaging etc. and food
Touching is easy the ink eaten, and mostly containing synthesis chemical component in ink formulations, non-natural raw material is extremely difficult to state food
The relevant criterion of drug, still cannot be by long-term or large amounts of food.From the angle of food safety, edible ink must have higher
Security level, it is more harmless to human body.
However also there is patent to prepare edible ink using edible material.But it is general due to often lacking in its formula
The various components to play a crucial role, auxiliary agent etc. in ink formulations, so effect in practical applications still has with general ink
Gap.
And in terms of ink pigment, there is patent to use the encapsulated by structures pigment of microcapsules, there is pigment in aqueous color paste
Effect dispersion, but it is not illustrated particular for edible aspect.Its raw material use aspect, which does not illustrate equally, is related to edible grade
Not.
In addition, pigment plays the function of colouring as the important component of ink in ink.In edible pigment side
There are synthetic food color and natural pigment in face.And natural pigment is more safe and reliable compared with synthetic food color, but most of natural
Pigment is oil-soluble, it is difficult to it is evenly dispersed in water-based system, and be easy to be fluctuated by environmental factor and be shown as pH is influenced
Reunite, be difficult to disperse or unstable color.
