Is fat-free butter replacement powder calorie-free?
No. The historical USDA entry named “butter replacement, without fat, powder” contains 373 kcal, 89 g carbohydrate and 1 g fat per 100 g. Its name should not be read as zero energy or literally zero fat. It is a different product from powdered real butter.1
Calories in 5 g and 10 g of dry powder
A weighed 5 g amount provides 19 kcal; 10 g provides 37 kcal. That 10 g also contains 8.9 g carbohydrate and 120 mg sodium. These weights refer to dry powder, not to an equal weight of a mixture made with water. The source's 80 g cup is not a recommended serving.
Is it the same as butter powder, margarine or plant-based butter?
No. Their fat and water contents can differ substantially. This generic record does not represent every brand sold today. If you have a powder made from real butter, do not use this low-fat replacement profile. Read the ingredients and nutrient label as well as the product name. The product distinction for Smart Balance Light spread likewise separates dry powder from a fat-based spread.
How should it be counted in cooking or baking?
Follow the mixing and use instructions for your product. Replacing butter gram for gram with this powder does not guarantee the same texture or result. Count the dry powder added to the whole recipe, then divide by the servings it produces. With its high carbohydrate proportion, low fat does not automatically make it suitable for a ketogenic plan. Calculate total carbohydrate for the amount you use instead of looking only at the fat or sugar line.
Can it be assumed vegan, dairy-free or gluten-free?
This historical food record does not supply a specific brand's complete ingredient and allergen list. Those properties cannot be assumed. For a milk allergy, coeliac disease or vegan diet, check an explicit statement on the product you intend to use.
