Gelatin Bloom Strength Types and Uses

When it comes to gelatin bloom, the term can mean one of two things. Bloom can either refer to the act of softening and melting gelatin before adding it to a recipe, or it can refer to the strength or firmness of the gelatin when it cools and forms. In this article, we’re going to refer to bloom in sense of the gelatin strength. We’ll cover the origins of gelatin bloom strength, explain some of the common bloom number ranges and determine how we can help you find the right gelatin for your application.

How Gelatin Bloom Strengths Originated

Back in 1925, Oscar T. Bloom, an American scientist, invented the Bloom Gelometer, an instrument used to measure the rigidity of gelatin or gelatin film. The measurement that is determined as a result of the process is referred to as “bloom strength.” Even though the Gelometer is no longer in use, the term still is. 

Gelatin bloom strengths can range from 30 to 325. With the measurement, higher numbers mean firmer results. The firmness or softness of a specific type of gelatin is mostly related to its viscosity. Bloom strength ranges tend to fall into three categories. 

Low Bloom Gelatin

Low bloom gelatins fall between the range of 50–125. Lower bloom gelatin comes from the early stages of the gelatin-making process. Since little time goes into making it, low bloom gelatin is very soft.

Medium Bloom Gelatin 

Medium bloom gelatins range between 175–225 in bloom strength. Gelatins in this range are often used for food. For example, gelatin with a bloom of 225 can be found in frostings, whipped cream stabilizers, marshmallows and canned hams.

High Bloom Gelatin 

High gelatin bloom strengths range from 225–325. These gelatins are made with cow or pig collagen and used in gelatin desserts, jelly fillings, cream fillings, jellied meat products, gelatin capsules and ballistic gelatin.

How Gelatin Bloom Strength Affects Price 

We established earlier that the higher the bloom strength, the firmer the gelatin will be. Another thing to keep in mind is that as the bloom strength number goes up, so does the price. This is because more steps are involved in making gelatins with higher bloom strengths. If we’re looking at a 10-step process, lower bloom gelatins are a result of the earlier stages and could be finished around step five. So, less steps will result in lower costs. But if you need a stronger gelatin, you will have to pay a little more since it’s the end product of a much longer development process.
