As fruit juice milk drink thickener, suspending agent, non-partisan high acyl gellan gum and gellan gum LT100 optimum dosage is 0.02%, carrageenan the optimum dosage was 0.02%, CMC of the optimum dosage was 0.3 %.
Gellan gum with little more than CMC, and the same amount of carrageenan.
Since the stability of the solution in less carrageenan and liquid particles larger poor taste, gellan gum as a single fruit juice milk beverage additives, than carrageenan, CMC and better performance.
However, gellan gum as a single additive, there are low viscosity, the shortcomings of excessive precipitation, mixed gum can increase the flavor and taste of milk drink, and to increase the viscosity of fruit juice milk drink, to improve the stability of milk drinks.
By orthogonal experiments, high acid balanced mixture of gellan gum was 0.02% the best combination of high acyl gellan gum, 0.015% carrageenan and 0.3% of the CMC, the lowest amount of precipitation finished 1.24%, LT100 Results cold rubber compound the best combination of 0.025% of the LT100 gellan gum, carrageenan and 0.02% 0.25% CMC, precipitation amount of 1.38%.
Viscosity too high too low will affect the taste, rubber compound of each group were moderate viscosity, taste good.Single-compound rubber stabilizer and a stabilizer no much impact on the pH, pH 4.0 to 5.0 to maintain the best flavor of apple juice.
In summary, the best fruit juice drink formula milk and 0.02% high acyl gellan gum, 0.015% carrageenan and 0.3% of the CMC, the lowest amount of precipitation samples, the best stability. |
