Permeability of Alginate Calcium Skin

The permeability of several pigments in the soft capsule beverage was studied in the paper. Some methods which control pigments's permeation were also researched like embedding the pigment and change the composition of the skin liquid. The results showed that the order of the permeability from bigger to smaller is lemon yellow, chlorophyl or β-carotin and lycopene. The effect of lemon yellow emdedding with β-cricoid dextrin on the permeability is not notable，however, the permeation of the pigments can be obviously restrained through adding xanthan gum or epichlorohydrin in the skin liquid.
