Do simple syrups need to be refrigerated?.How do you make simple syrup last longer?.How do you keep simple syrup from going bad?.What is the shelf life of simple syrup?.How do you sterilize simple syrup bottles?.Can you store simple syrup in a plastic bottle?.Or maybe a piece of scrap copper pipe from your shop? A classier way would be to get a little silver creamer pitcher which would both retard mold as my silver cup did and be easy to pour from into your coffee. addition of metal as copper or silver retarded mold growth over the experimental period of 1 week. below: 10 and 20 penny cups (30 pennies not shown) and silver cup.įor sugar syrup left open at room temperature. Jars with 10,20 and 30 pennies have no mold colonies yet. Jar with 5 pennies developed mold for the first time this morning. Jars with 2 pennies had a few mold colonies. The mold looks like aspergillus (bread mold) and is floating on top. Jars with only syrup and no pennies had mold colonies by day 3 and they are easy to see now. Here are results as of this AM 11/9 at 1 week. Subsequent jars had 2 pennies (x2 jars), then 5, 10, 20 and 30 pennies.Įxperiment is ongoing. First 2 jars (0) were controls with only syrup, no pennies. These are American pennies which I washed with dishsoap and rinsed. To simulate a copper metal cup I used pennies. I did not have a copper cup but I had a silver one - also 150 ml. Approximately 150 ml syrup in each of 8 jars. I made the sugar syrup with a 1:1 sugar and water mix, heated in a saucepan. Here is the setup as of 11/2 - 1 week ago. This premise is testable experimentally and that is what I did. Especially for you, because you doubted and you were right to doubt. The amount that leaches into the syrup will prevent mold growth, I here assert. Note: We have a separate question on whether this is safe, Is copper safe for long-term food storage?.īust out your Moscow Mule mug and keep your syrup in that. This publication suggests 50g Sodium Benzoate powder with 1ml Cherry flavoring and 999mL of Simple Syrup (thereby resulting in ~0.05%).įor further reference: Here is the Scientific Committee on Consumer Products Opinion on Benzoic Acid and Sodium Benzoate See, e.g., A comparative study of the effects of the two preservatives, sodium benzoate and potassium sorbate on Aspergillus niger and Penicillium notatum or Sodium Benzoate and Potassium Sorbate Preservatives in Juices and Fruits. Looking at a few papers, I would guess that concentrations around 0.05% would be an adequate range. Order Food-Grade powdered Sodium Benzoate and do math to figure out how much you need to add to your syrup.Call SnoWizard and ask what the Sodium Benzoate concentration is in their product, then do some math with those numbers or.If you want to add Sodium Benzoate to your Simple Syrup, and you want to ensure you are below the FDA set maximum, you could either: 184.1733) restricts usage to "a maximum level of 0.1 percent in food." The FDA Regulation regarding Sodium Benzoate (21 C.F.R. For example, Hypothermias Sodium Benzoate suggests 1/4 oz of Sodium Benzoate to 1/2 oz Citric Acid, which is pretty different from SnoWizard's instructions. SnoWizard has their concentration of Sodium Benzoate in their product while others use a different concentration (presumably, I cannot find datasheets on any of the products). Their products are an aqueous solution of Sodium Benzoate (a salt) - but SnoWizard does not tell you the concentration of that solution. That SnoWizard link refers to their specific products.
