The present invention relates to a technology for preparing fermented foods, particularly kimchi, and relates to a kimchi preparation method and kimchi prepared using same, the method reducing off-odor, improving flavor and preference, and ensuring long-term storage and hygiene through salinity control of salted Chinese cabbage, optimization of a composition of lactic acid bacteria in kimchi seasoning, multi-stage aging, and a ultra-high pressure sterilization (HPP) process. In addition, a lightly fermented taste, a well-fermented taste, and a fully fermented taste can be selectively implemented using aging control. For example, a low acidity region (acidity of approximately 0.1% to 0.3%), a medium acidity region (acidity of approximately 0.31% to 0.9%), and a high acidity region (acidity of approximately 0.91% to 1.7%) can be stably ensured, and a combination of lactic acid bacteria strains (e.g., Leuconostoc, Lactobacillus, and Weissella spp.), the ratio of Chinese cabbage to seasoning, and a lactic acid bacteria inoculation amount are optimized such that fermentation variability can be reduced and reproducibility between products can be increased.

The present application belongs to the field of food processing, and provides a pickled vegetable and a preparation method thereof; a pickled vegetable mother liquor containing oligosaccharides and mint extract is prepared, a composite microbial inoculum composed of lactic acid bacteria and Weissella is inoculated into the pickled vegetable mother liquor, and the inoculated pickled vegetable mother liquor is injected into pretreated fresh vegetables for fermentation. In the fermentation process, first, the facultative anaerobic lactic acid bacteria consume the oxygen in the fermentation jar, and the oligosaccharides proliferate the Weissella, and the generated carbon dioxide speeds up the formation of an anaerobic environment. In this process, the yeast can still move, and the bacteriostatic substance produced by the movement of the lactobacillus has a weak inhibitory effect. Therefore, the addition of the mint extract improves the bacteriostatic effect of the yeast, and at the same time, inhibits the growth of nitrite. The acidic environment produced by the movement of the lactic acid bacteria and the Weissella gradually degrades the nitrite. Compared with the prior art, not only can the growth of miscellaneous bacteria in the fermentation of the pickled vegetable be inhibited, and the pickled vegetable "flowering" be avoided, but also the safety and sensory quality of the pickled vegetable are improved.

The goal is to artificially ripen unripe green plums in a short period of time, thereby providing plums that are equivalent in quality to naturally ripened, fully mature plums. [Solution] In the decomposition step S4, the decomposition of cyanogenic glycosides such as amygdalin contained in the pulp of raw plums promotes the production of hydrogen cyanide and benzaldehyde.

The present invention aims to provide a novel flavor composition that overcomes the risks or unpleasant off-flavors associated with existing salt substitutes and achieves enhanced saltiness at low cost and in a simple manner. [Solution] The present inventors have found that the saltiness enhancement ratio of a flavor composition based on a salt substitute containing chloride ions is proportional to the molar ratio of chloride ions to sodium ions in the presence of anions of organic acids or inorganic acids other than hydrochloric acid as saltiness enhancers. By focusing on this molar ratio, the intensity of the anion effect can be systematically adjusted while suppressing the sodium ion concentration in food and beverages. As a result, a composition that provides a saltiness intensity equivalent to or greater than that of salt can be efficiently optimized. The present invention provides a flavor composition that achieves saltiness enhancement at low cost and in a simple manner by optimizing the composition by the above method.
