(a) Schematic comparison of pattern of release of xylanase from xylanase@Lys-zeolite and Zeozyme NPs in the simulated variable pH conditions and retention time of passage through the GI tract. (b) GI tract pH profile of poultry showed by color scale. (c) Xylanase cumulative release comparison between xylanase@Lys-zeolite and Zeozyme NPs at 41 °C, where the xylanase release was evaluated by stirring samples at pH 5.2 (for 12 min), pH 1.6 (for 15 min), pH 2.5 (for 20 min), pH 6.0 (for 87 min), and pH 7.1 (for 80 min). (d) Enzyme activity of released xylanase comparison between xylanase@Lys-zeolite and Zeozyme NPs at 41 °C based on pH and retention time of GI.
