Abstract

The invention relates to a fruit, specifically to a preparation method of candy orange peel pigment, and belongs to the technical field of food additive processing. The preparation method comprises the following steps of: washing fresh candy orange peel, drying, crushing, immersing in 95% of ethanol, carrying out water-bath extracting for two times, centrifuging the extracting solution, carrying out vacuum concentration, and drying to obtain a candy orange peel pigment crude product. The extracting solution contains high pigment content. The pigment has few impurities and is pure in color. The main component of the pigment extracted from the orange peel is yellow pigment. The yellow pigment of the orange peel belongs to a flavonoid compound and can be widely applied in food additives, drug intermediates and other products.

Description

technical field [0001] The invention relates to a fruit, in particular to a preparation method of rock sugar orange peel pigment, which belongs to the technical field of food additive processing. Background technique [0002] Pigments are an important part of current food additives. As we all know, food coloring is often divided into two categories: natural coloring and synthetic coloring. Synthetic pigments have been widely used in food dyeing due to their bright color, strong tinting strength, good stability, odorless and tasteless, uniform quality, and low cost. However, as people pay more and more attention to their own health, the harm of synthetic pigments to human health has attracted more and more attention. Natural pigments are not only safe and reliable to use, but also have considerable nutritional and medical care effects. Therefore, replacing synthetic pigments with natural pigments is an inevitable trend in the application of pigments. Bingtang orange is an ...
