Hàn the doesn’t change the color of giò chả, making it difficult to differentiate visually. The best way to identify it is through taste. Pure giò chả should have a sweet and fragrant taste, soft and not dry or tough.

Using turmeric: You can test giò chả using turmeric. Hàn the is acidic, while turmeric is sensitive to acid. You can soak a piece of paper in fresh turmeric water and press it onto the surface of the giò chả. If the paper turns from yellow to red after 1-2 minutes, it means that the giò chả contains hàn the. Alternatively, you can rub turmeric on a piece of giò chả and observe. Similarly, you can also use litmus paper to press onto the giò chả. If they turn red or orange, it has been contaminated with hàn the.

Furthermore, when cutting slices of giò chả contaminated with hàn the, you will find them soft and smooth, while non-contaminated giò chả usually has holes when cut. Standard giò chả without hàn the feels slightly wet when touched, with an ivory color that slightly tends towards pink. On the other hand, giò chả containing hàn the may feel slightly rough on the surface. Giò chả without hàn the sticks to the knife when cut, while giò chả containing hàn the slides smoothly.

You can easily detect deadly bacteria in sausages by using a common vegetable like cabbage. Simply take a sample of the sausage and place it in a bag with shredded cabbage. If the sausage is contaminated with harmful bacteria, the cabbage will turn pink or red due to the production of nitric oxide.

The pink or red color is a result of the chemical reaction between the bacteria and the cabbage. When harmful bacteria are present, they break down the nitrate compounds in cabbage and release nitric oxide, which has a pink or red color.

The color change can occur within a few hours to a day. However, it’s important to note that the sensitivity of this method may vary depending on factors such as the type and concentration of bacteria present.

While using cabbage is a simple and inexpensive method for detecting harmful bacteria, it may not be as sensitive as other laboratory techniques. It is also important to use fresh cabbage and follow proper sampling and testing procedures to ensure accurate results.
