Buyers should prioritize color consistency, texture, and brine clarity. High-quality garlic in brine should be creamy white to pale ivory; any yellowing or spotting indicates oxidation or poor preservation. The texture must remain firm and crisp rather than mushy. Furthermore, the pH level should be strictly controlled between 3.5 and 4.5 to inhibit microbial growth, and the salt concentration (salinity) should typically range from 18% to 22% depending on the intended shelf life and further processing needs.
