You can easily save the nutrition label by saving the provided embed code. Once you've finalized your ingredients and servings click or tap "embed this label," located under the nutrition label, to generate a code that you can insert into your blog or save to reference later.

The nutrition facts label is useful if you're tracking calories or just want to be more informed about your diet, but this recipe calculator is also helpful for making smarter food decisions. You might see an error message pop up once you analyze your recipe. Here are a few common ones and how to fix them:.

Please make sure that you are using the most up-to-date version of your web browser in order to avoid potential errors. This information makes it easier for consumers to make better informed food choices. But how do you work out what the nutrient values should be? This post digs into the what, why and how when it comes to educating consumers about your food product.

Nutritional information is a collection of nutrients and their values that are present in a food product. The most common nutrients include energy kilojoules or calories , protein, fat, saturated fat, carbohydrate, sugars, and sodium a component of salt. Generally, data per g and also per serving size is required. Depending on where you are located, the law will stipulate what nutrients are required to be declared.

There may be exemptions depending on the type of food that you manufacture. The following table provides a general overview. If you make a nutritional claim on your food packaging or food label you may also be required to include that data as part of your nutritional information.

There are two ways to determine the nutrition information of your food products. You can determine by laboratory analysis or by calculation. Laboratory Analysis involves you sending your finished product to a laboratory where they will physically test the product using approved methods. You can complete this process manually or use a nutrient software calculator. The manual calculation can be very time-consuming if you have multiple products.

I prefer using purpose-built software Foodworks as it also provides additional information that is required to appear on a food label. A calorie is a unit that is used to measure energy.

The Calorie you see on a food package is actually a kilocalorie, or 1, calories. A Calorie kcal is the amount of energy needed to raise the temperature of 1 kilogram of water 1 degree Celsius. Sometimes the energy content of food is expressed in kilojoules kj , a metric unit. One kcal equals 4. So the Calorie on a food package is 1, times larger than the calorie used in chemistry and physics. The original method used to determine the number of kcals in a given food directly measured the energy it produced.

The food was placed in a sealed container surrounded by water--an apparatus known as a bomb calorimeter. The food was completely burned and the resulting rise in water temperature was measured.

This method is not frequently used today. The NLEA requires that the Calorie level placed on a packaged food be calculated from food components.
