Description
Technology neighborhood
The present invention relates to a kind of edible ink and preparation method thereof, particularly a kind ofly prepare the method for edible ink to receive crystalline cellulose for one of batching.
Background technology
Printing-ink, as main coloring material, has very important status in printing with packaging industry.But some traditional ink component comprise the part objectionable impurities very large to harm, solvent type ink as being widely used in flexible packaging made from plastic Printing Industry contains volatile carcinogens, particularly by this ink printing on the packaging of tobacco and wine, edible packing material, food, the product such as medicine and toy for children time, directly will affect human health.Although scientist starts research direction to turn to the environment-friendlyink ink not containing objectionable impurities now, as water-based UV ink, but namely this ink itself can not be eaten, and cannot directly print on the surface of food, medicine etc. again.If develop a class ink directly can be printed on food, the surface of medicine and printability is good, not only impart food and the abundant color of medicine, and its development space of having tool large, market outlook are very wide.Edible ink can be used to cure cake, make cream and ice-creams etc. in daily life, makes its color abundanter, more can trigger the appetite of human consumer, increase the magnetism to children; Food pack directly carries out edible ink printing and can also reduce the pollution that general printing-ink brings food very efficiently; Directly print out the landscape image etc. of all kinds of pattern as beauty at drug substance surface, not only can cater to the feature of outpatients mental state, medicine is personalized, the effect of comfort, enlightenment also can be brought to a certain extent to patient.But the application of edible ink is uncommon in the market.
In order to having a strong impact on of alleviating that oil crisis brings; some scientific research institutions and strong company increase the R&D intensity of not petroliferous printing-ink; along with research deepens continuously, the edible ink formula of some maturations and the equipment of applicable edible ink printing obtain application.As Procter & Gamble utilizes edible ink to print on the surface of " product visitor " potato chips (Pringles), and obtain good market effect; Japan's printing press manufacturing concern agate this take Ma Yingde company and successfully have developed a kind of edible ink printing press MMP1300BT, utilize this printing press directly edible ink can be printed on food surfaces.In addition Dutch countries use research institute develops a 3D food " printer ", with chocolate or other food materials for the food that a certain amount of edible ink can print various moulding uniqueness added by raw material; DouglasRStewart etc. develop a kind of new edible ink printing process, the base mateiral first being utilized by edible ink jet printing appts to spray to edibility forms ornament layer, and then is applied in cake production technique by this ornament layer; ArunVShastry etc. have developed a kind of edible ink being main component with edible wax, pigment, fat etc., and by its spray printing on the substrate, printed images precision is minimum reaches 300dpi.Liu Zhuan etc. have developed a kind of heat-resistance type edible ink, and under the hot conditions of 120 DEG C, ink spectra reflectivity variable quantity is only 1.72%.The domestic report about edible ink is rare, and technology does not reach ripe degree, and only several company can produce edible ink and its price is high, is not suitable for scale operation.
Mierocrystalline cellulose in human diet is mainly contained in vegetables and rough machined cereal, although can not digestedly absorb, has promotion intestines peristalsis, is beneficial to the functions such as ight soil discharge.Crystalline cellulose of receiving still belongs to Mierocrystalline cellulose.Eatable cellulose is a kind of material of not digested absorption, thinks in the past " refuse ", thinks now and is called as the 7th kind of nutrient substance by its important role in guarantee human health, extending life.
Summary of the invention
The object of the invention is to provide one to receive crystalline cellulose edible ink and preparation method thereof.
The technical solution used in the present invention is:
