It can be seen from the combination of application examples 1 to 3 and application examples 4 to 6 and the combination of table 2 that pectin prepared by combining citrus dietary fiber, aspartic acid and high-fat pectin and casein-modified white kidney bean dietary fiber in the solidified liquid can improve the freeze stability of freeze-resistant heart bursting beads and improve the dispersion stability.
It can be seen from the combination of application examples 1 and 7-9 and the combination of table 2 that the strength of the wall material film layers of application examples 7-8 affects the effect of the ice crystal structure in the ice cream easily penetrating into the wall material film layer during the freezing process, thereby affecting the coating effect of the inner core.
The addition of chitosan in application example 9 can provide space for the growth of ice crystals, so that the external ice crystal structure is not easy to penetrate into the inner core feed liquid to influence the stability and fluidity of the inner core feed liquid.
It can be seen from the combination of application examples 4 and 10 and the combination of table 2 that the addition of aspartic acid in pectin in application example 10 can improve the toughness of the film layer, so that ice crystals are not easy to penetrate into the wall material film layer, and the stability of the material liquid of the inner core is ensured.
As can be seen from the combination of application examples 5 and 11 and the combination of table 2, the common citrus dietary fiber in example 11 has hygroscopicity, while the light cream of the milk ice cream liquid contains rich lipids, and the lipophilic property of casein is utilized to be matched with the lipophilic effect of the white kidney bean dietary fiber, so that the wall material film layer can be endowed with a certain degree of lipophilicity, thereby improving the dispersion stability of the freeze-proof heart bursting beads in the milk ice cream liquid.
