The hypothesis for the experiment was that if the apples are soaked in 4 different preservatives (lemon juice, salt water, club soda) then the lemon juice will.
Experiments show that only the sulfur dioxide molecule has an antibacterial effect. Sulfur dioxide inactivates by combining with compounds derived from wine.
We've got you covered! these 20 science experiments are motivating and educational – our favorite.

Preservatives can be grouped into three general types: antimicrobials that block growth of bacteria, molds or yeasts; antioxidants that slow oxidation of fats and lipids that leads to rancidity.
In this science fair experiment, we'll be testing the efficacy of various methods of food preservation.
Scientists have also learned that preservatives can be added to foods to slow the spoiling process. Some of the most common preservatives for slow the spoiling process include sulfites, benzoates, and nitrates. These preservatives can be found on the ingredient labels of many different foods today.
Researchers from the environmental working group say nearly 1,250 products contain the shelf life-extending chemical tert-butylhydroquinone, or tbhq. They find this preservative, used in pop-tarts, rice krispies treats, cheez-its, and countless other products, disrupts immune health in both animal and non-animal tests.
June 2018 preservatives are excipients essentially needed in pharmaceutical multi-dose formulations to prevent microbial growth. Among available substances, phenol is widely used for parenterals, however, it is known to interact with non-ionic surfactants like.
