Abstract

The invention discloses a preparation method of a saffron crocus extract colorant and a beet root extract colorant and an application thereof, and the preparation method comprises the following steps:a, carrying out ultrasonic water extraction on saffron crocus to obtain a saffron crocus aqueous extract; b, juicing the beet roots; c, respectively filtering the saffron crocus aqueous extract and the beet root juice obtained in the step b, and performing standing; d, respectively encapsulating by using Arabic gum modified starch; e, respectively encapsulating the chitosan; and f, respectively freezing the two obtained solutions at -30 DEG C overnight, and grinding the frozen solutions into powder to obtain the saffron crocus extract colorant and the beet root extract colorant. The preparedcolorant is high in stability, is most stable in coloring when being applied to chewing gum, is good in taste and is easy to store.

Description

technical field [0001] The invention relates to the field of food technology, in particular to a preparation method and application of a saffron extract colorant and a beetroot extract colorant. Background technique [0002] At present, in the preparation process of chewing gum, chemical pigments are mainly used, and the use of chemical pigments is unsafe. Thereby people more and more like to use natural pigment, but natural pigment exists to heat, to the shortcoming of unstable pH, the color of the chewing gum that prepares is not good, therefore especially important to improving the stability of natural pigment. [0003] The pigment contained in saffron is mainly crocetin, which is a natural pigment of carotenoids, and is an esterification product formed by gentiobiose and crocetin. The melting point is 186°C, the crystal is dark red, and it appears orange in aqueous solution. Crocetin will be lost in high temperature, strong light, strong acid and strong alkali environm...
