Description

Technical Field

[0002] Traditional Chinese solid-state fermented vinegar is known for its rich aroma, mellow taste, and high nutritional value, making it a daily necessity for many. Its market sales continue to grow, with Zhenjiang vinegar, Shanxi aged vinegar, and Sichuan Baoning vinegar being typical examples. Chinese vinegar products primarily use rice and sorghum as raw materials, undergoing alcoholic fermentation, acetic acid fermentation, and post-fermentation aging. Acetic acid fermentation is a crucial step, involving the collaborative work of a complex microbial community. This process transforms carbohydrates and proteins in the raw materials into organic acids, amino acids, and other flavor compounds, laying the foundation for the unique flavor and quality of vinegar. Given that traditional Chinese solid-state vinegar production mainly utilizes an open fermentation system, environmental conditions such as temperature, dissolved oxygen, and humidity significantly influence the sensory quality of the vinegar product by affecting the microbial community structure within the vinegar mash.
