In this brief guide, we’ll address the query: “Can you freeze agar jelly?” Also, we’ll explore how agar jelly should be stored, what agar jelly is, how it is made, what the nutritional content of agar jelly is, and is it healthy to eat agar jelly? 

Can you freeze agar jelly

Freezing agar jelly is not recommended. Agar is more firm than gelatin-based products and as a result, is more susceptible to detrimental changes that freezing may inflict. 

Namely, the loss of texture and moisture may result in agar jellies losing their structure and therefore, making the jelly less palatable. 

Aesthetically, the appeal of agar jelly is that it is firmer (less “jiggly”) and has a more solid consistency. Freezing would prove destructive and therefore, is contraindicated. 

How should I store agar jelly

Agar jelly should be stored in refrigeration, ideally at a temperature of 5°C or less, but not lower than water’s freezing point. This is done to prevent the growth of microbes that may find their way to the agar’s surface and to preserve moisture. 

In refrigeration, agar jelly can keep for 5 to 7 days before it loses its structure, and therefore, should be consumed within said period. 

What is agar jelly

Agar jelly alludes to a jelly made with agar, a product obtained from processed reg algae, that has its origins in Asian cuisine. 

Agar is a carbohydrate mixture that is used as a gelling agent, and it characteristically confers a more solid texture than other products such as collagen-based gelatins and pectins. 

Due to the plant-based origin of agar, jellies made with it are considered suitable for those on stringent plant-based diets such as vegans.

As it is essentially flavorless, agar can be made into a variety of flavors of jelly.  

Agar can be purchased in Asian food stores in some convenience stores and can be found as a powder, in bars of flakes, in bags of flakes, and strands, though the agar must first be dissolved and homogenized in hot water for it to properly set. 

Below, we’ll describe the main outlines of how agar jelly is made. 

How is agar jelly made

Agar jelly is made by first heating water to its boiling point and then pouring the agar (at a previously established ratio). 

The agar should fully dissolve in the hot water; no clumps or buildups should be visible, and then, other components such as sweeteners, coloring agents, and flavor extracts can be added. 

The mixture should simmer for the amount of time indicated by the recipe, and while still on the warmer side, it should be poured into molds or basins.

To be clear, agar jelly doesn’t need to be refrigerated to solidify and can be left to cool on a countertop while covered with cling wrap or any other barrier to keep particles out. 

After about an hour, the agar jelly will have solidified and can be placed in the fridge to chill until served.  

From there, agar jelly can be enjoyed as a dessert on its own, or be used to make other dishes such as layered cakes, mosaic jellies, etc. 

What is the nutritional content of agar jelly

Is eating agar jelly healthy? 

Eating agar jelly can be considered healthy, so long as the end product of the recipes is low in calories and added sugars. 

Agar jelly itself is low in calories, and when used as a gelling agent, it can be used to give volume, which may contribute to an early feeling of satiety, without consuming as many calories. 

As a product derived from seaweed, agar may stimulate digestive function, skin health, stimulate immune function, and provide other benefits. 

Also, as a plant-based product, it is indicated as a substitute for animal products such as collagen-based gelatins, though it lacks their amino acid content. 

Perhaps most importantly, readers should be wary of added sugars in their recipes, as consuming high amounts will have detrimental effects on their health, and the sugar content may outweigh any health benefits of using agar jelly.
