Answer 1

Sulphites are the preservatives tested in the poison squad clinical trials used in winemaking and not banned under the 1906 Act, which can cause asthmatic reactions in some people. Sorbic acid, benzoic acid, and propionic acid are other preservatives still in use today.

Step-by-step explanation:

The preservative used in the wine industry that was tested in Harvey Wiley's "clinical trials" but not banned under the Pure Food and Drug Act of 1906 and is still widely used today is sulphites.

Sulphites are effective in preventing browning of foods and have been used since ancient times in winemaking. While they are generally safe and can be metabolized by the body, sulphites can cause asthmatic reactions in some individuals.

Other chemical preservatives still used today include sorbic acid, benzoic acid, and propionic acid, along with their soluble salts like sodium benzoate and potassium sorbate

which are added to various food products to inhibit microbial growth and spoilage.
