Applications of Sodium Acetate
Biotechnological
Sodium acetate is used as the carbon source for culturing bacteria. Sodium acetate is also useful for increasing yields of DNA isolation by ethanol precipitation.

Concrete Longevity
Sodium acetate is used to mitigate water damage to concrete by acting as a concrete sealant, while also being environmentally benign and cheaper than the commonly used epoxy alternative for sealing concrete against water permeation.
Food
Sodium acetate may be added to food as a seasoning, sometimes in the form of sodium diacetate, a one-to-one complex of sodium acetate and acetic acid, given the E-number E262. It is often used to give potato chips a salt and vinegar flavour, and may be used as a substitute for vinegar itself on potato chips as it doesn't add moisture to the final product. Sodium acetate (anhydrous) is widely used as a shelf-life extending agent and pH control agent. It is safe to eat at low concentration.
Buffer Solution
A solution of sodium acetate (a basic salt of acetic acid) and acetic acid can act as a buffer to keep a relatively constant pH level. This is useful especially in biochemical applications where reactions are pH-dependent in a mildly acidic range (pH 4–6).
Heating Pad
Sodium acetate is also used in heating pads, hand warmers, and hot ice. A supersaturated solution of sodium acetate in water is supplied with a device to initiate crystallization, a process that releases substantial heat.

Sodium Acetate Trihydrate in Food
Enhancing Sour Taste
Sodium acetate trihydrate can provide a tangy flavor to foods, especially snacks, sauces, condiments, pickles, and cheese. It can also mask unpleasant tastes or odors in some foods.
Adjusting Ph
Sodium acetate trihydrate can act as a buffer to maintain a stable pH in foods, especially acidic or alkaline foods. It can also neutralize excess acidity or alkalinity in foods, which can affect the texture, color, or shelf life of foods.
Preserving Food
Sodium acetate trihydrate can inhibit the growth of bacteria, molds, and yeasts in foods, especially meat, fish, dairy, and fruit products. It can also prevent oxidation and browning of foods, which can affect the quality and appearance of foods.
Safe Food Additives
Sodium acetate trihydrate is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA). The acceptable daily intake (ADI) for sodium acetate (anhydrous or trihydrate) is not specified by the Joint FAO/WHO Expert Committee on Food Additives (JECFA), which means that it can be consumed at levels normally found in foods.
How to Use Sodium Acetate Trihydrate Safety:
Here are some tips on how to use sodium acetate trihydrate safely:
1)Wear protective gloves, goggles, and clothing when handling sodium acetate trihydrate. Avoid direct contact with the skin, eyes, and mucous membranes.
2)Store sodium acetate trihydrate in a cool, dry, and well-ventilated place. Keep it away from heat, sparks, flames, and other sources of ignition.
3)Do not ingest sodium acetate trihydrate. If swallowed, rinse the mouth with water and seek medical attention immediately.
4)Do not inhale sodium acetate trihydrate. If inhaled, move to fresh air and seek medical attention if symptoms persist.
5)Do not dispose of sodium acetate trihydrate in the drain or the environment. Follow the local regulations for waste disposal.
6)Read the label and the safety data sheet (SDS) of sodium acetate trihydrate before using it. Follow the instructions and warnings carefully.
How to Store Sodium Acetate Trihydrate
Industrially, sodium acetate trihydrate is prepared by reacting acetic acid with sodium hydroxide using water as the solvent. Therefore, it is important to store trihydrate sodium salt properly to prevent it from losing its water of crystallization and becoming anhydrous sodium acetate, which has different properties and applications.
Keep It in a Sealed Container
The best way to store trihydrate sodium salt is to keep it in a sealed container in a cool, dry and dark place. The container should be made of glass, plastic or metal that does not react with the salt or the moisture. The container should also be labeled with the name, formula, CAS number and hazards of the salt. The storage temperature should be below 58 °C (136 °F), which is the melting point of trihydrate sodium salt. The storage humidity should be below 65%, which is the relative humidity at which the salt starts to deliquesce.
Don't Expose It to High Temperature Or Humidity
If the trihydrate sodium salt is exposed to high temperature or humidity, it may melt, liquefy or solidify into a hard mass. This can make it difficult to use or measure accurately. If this happens, the salt can be restored by heating it gently in an oven or a water bath until it melts completely, then cooling it slowly in a desiccator or an airtight container until it crystallizes again. Alternatively, the salt can be dissolved in water and then recrystallized by evaporating the water.
