Optimization of Wall Materials for Astaxanthin Powder Production from Shrimp Shell Extract Using Simplex Lattice Mixture Design

Table 6

Predicted and experimental values of the responses at optimum conditions.

	Encapsulation yield (%)	Encapsulation efficiency (%)	Astaxanthin content (μg/g)	DPPH radical scavenging power (%)
Predicted values^a	94.6a	91.8a	46.1a	64.0a
Experimental values^b	a	a	a	a

Note: ^aPredicted using response surface quadratic model. ^b deviation of triplicate determinations from experiments. Data within a column with the same lowercase letters are not significantly different at .
