Purpose: This study aimed to investigate the flavor characteristics of the Gochujang condiment and its flavor compounds when it was heated with the addition of allulose.
Methods: The Gochujang condiment samples were prepared with the addition of 0%, 25%, 50%, 75%, 100% allulose, and sugar for sweetness and heated for 30 minutes. The solid-phase micro-extraction (SPME) method was used to capture the flavor aroma, gas chromatography-mass spectrometry (GC-MS), and gas chromatography-olfactometry (GC-O) were used for the analysis.
Results: The volatile flavor components were analyzed to evaluate the flavor characteristics of the processed Gochujang condiment. A total of 43 volatile flavor components were identified with the heat treatment, among which diallyl trisulfide showed the highest peak, and diallyl disulfide, methyl-2-propenyl trisulfide, β-phellandrene, and β-caryophyllene also had high peaks. These five high-peak ingredients play an important role in determining the taste of the Gochujang condiment. It was confirmed that the volatile component was diallyl trisulfide, which increased as the allulose content increased. A total of 16 flavoring active ingredients of the condiment were identified. Also, most sulfur compounds and terpene were identified. Allyl methyl disulfide, dimethyl trisulfide, diallyl disulfide, β-phellandrene, and methyl 2-propenyl trisulfide played an important role in the flavoring of the Gochujang condiment.
Conclusion: The main volatile components of the flavor compounds generated by the heat treatment included diallyl trisulfide, diallyl disulfide, methyl-2-propenyl trisulfide, β-phellandrene, and β-caryophyllene with high peak areas. The quantum of diallyl trisulfide increased as the allulose content increased. Allyl methyl disulfide, dimethyl trisulfide, diallyl disulfide, β-phellandrene, and methyl 2-propenyl trisulfide were identified as flavoring active compounds, and each of these contributed to the flavor of the Gochujang condiment.
