Consumer Perception on the Redness and Off Flavor Upon Stored Red Chili Paste with Hypoiodous Acid Treatment

Abstract

Abstract Red chili has a short shelf life because its respiration rate increases quickly. The development of pretreatment with hypoiodous acid (HIO) to extend the shelf life of agricultural products is now underway. This study intends to determine the impact of HIO treatment on the color and flavor of red chili paste during storage, which was employed as a quality indicator at the level of consumer perception. Red chili was used for the treatments, which were carried out by soaking it in 10 mM HIO for 15 minutes, whereas pure water was used for the control treatment. By reacting 20 mM H2O2 and 20 mM KI, HIO was produced. Every day for seven days, the redness value and scent were analyzed. The average and standard deviation were calculated to generate the data, which was then plotted with error bars. The outcomes showed that, starting at 51.55 and 54.10, the redness values for the control and HIO treatments were 42.94 and 43.71, respectively. The findings also revealed that whereas off flavor first appeared in the control treatment on the third day of storage, it first appeared in the HIO treatment on the seventh day. In conclusion, HIO therapy may limit the loss of redness and guard against changes in the flavor of red chili paste.
