Description
Summary:The optimum processing conditions for green laver chips were determined using response surface methodology (RSM) to improve taste and reduce off-flavors by applying reaction flavor and air-frying techniques. The optimum composition (<i>w</i>/<i>w</i>) for the chips included 20% green laver, 20% hairtail surimi, and 60% flour. Additional ingredients included distilled water (90 mL) with GDL (3 g), NaHCO₃ (2 g), salt (1 g), sugar (12 g), roasted soybean powder (1.5 g), and reaction flavor solution (RFS, 10 mL). The mixture was kneaded, shaped, dried at 50 °C for 2 h, and air-fried at 195 °C for 80 sec. The resulting green laver chips showed overall acceptance and brittleness values of 7.00 ± 0.74 and 5.89 ± 0.59 N, respectively, with absolute residual errors of 8.43% and 7.07%. The optimum reaction flavor precursors for green laver chips were determined to be threonine (1.0 g%), proline (1.0 g%), glycine (1.4 g%), methionine (0.05 g%), and glucose (2 g%). Flavor analysis revealed that green laver chips with reaction flavor (GLCR) contained 13 alkylpyrazines with corn-like and nutty odors, and 2-acetylpyrrole, which contributed a popcorn-like odor. In contrast, green laver chips without reaction flavor (GLC) predominantly contained straight-chain aldehydes with undesirable odors. The heating process in the air fryer appeared to reduce the aldehyde content and promote pyrazine formation, significantly enhancing GLCR’s flavor.
