Ice cream generally contains seven categories of ingredients: milk fat, milk solids-not-fat (the lactose, proteins, minerals, water-soluble vitamins, enzymes, and some minor constituents), sweeteners, stabilizers, emulsifiers, water, and flavours (1). The fat in an ice cream mix can either come from dairy sources (e.g. milk or cream), or from vegetable sources (e.g. coconut oil, palm oil, palm kernel…

Why are stabilizers used in ice cream?
11 MINUTE READIce cream generally contains seven categories of ingredients: milk fat, milk solids-not-fat (the lactose, proteins, minerals, water-soluble vitamins, enzymes, and some minor constituents), sweeteners, stabilizers, emulsifiers, water, and flavours. In this post, we’ll be looking at why stabilizers are used in ice cream. You might also like to read: Cuisinart ICE-100 Ice Cream…
Fiber in ice cream
The use of fiber in ice cream increases its nutritional value, improves texture, prolongs shelf-life, and can replace between 25% and 50% of the fat. In this post, we will be looking at the use of wheat fiber, oat fiber, inulin, apple fiber, and orange peel fiber in ice cream production. You might also like…

In this post, we’ll be looking at the role of fat in ice cream. You might also like to read: Cuisinart ICE-70 Ice Cream Maker…
Why is corn syrup used in ice cream?
18 MINUTE READ Sweeteners commonly used in ice cream formulations include cane and beet sucrose (‘table sugar’), maltodextrin, corn syrup, high maltose syrup, dextrose, fructose or high fructose corn syrup, maple syrup or maple sugar, invert sugar, honey, brown sugar, and lactose. Goff & Hartel (2013) note that the most common choice of sweetener in ice cream is…
Sugar in ice cream

Locust Bean Gum in Ice Cream
12 MINUTE READ Stabilizers used in ice cream production fall into the following categories: seed gums; microbial gums; seaweed extracts; proteins; plant exudates; pectins; and cellulosics. In this post, we’ll be looking at locust bean gum, a seed gum. Along with guar gum, carboxymethyl cellulose (also known cellulose gum), and carrageenan, it is the most frequently used stabilizer for regular ice…
How to calculate an ice cream mix
Below is the Excel spreadsheet I created to calculate my ice cream mix. It’s based on the calculations in Ice Cream (7th Ed) by Professor Doug Goff and Professor Richard Hartel, which I highly recommend reading. There are no restrictions on the use of this spreadsheet so feel free to download and use it as you…
Ice crystals in ice cream
12 MINUTE READ The best ice creams in the world have a smooth and creamy texture. This creamy texture, primarily associated with a high fat content, is also determined by the average size of the ice crystals. Ice crystal size is governed by the mix formulation, as well as by factors relating to the freezing…
Stevia in ice cream
14 MINUTE READ In this post, I’ll be covering the use of stevia rebaudiana (Bertoni) as a natural sweetener in ice cream. I’ll cover the sweetness potency, flavour profile, and the sweetness temporal profile of stevioside and rebaudioside A, the two main compounds providing sweetness in stevia. I’ll also cover the Acceptable Daily Intake (ADI), metabolism, stevia and diabetes,…
