For some types of fruits, you may have better results, as we discussed earlier, the pectin profile in each fruit and vegetable varies so for example if you were to make strawberry jam, you would end up with a runnier consistency.

Liquid pectin needs to be stored in your refrigerator. In most cases, the pectin you make at home will be liquid. It will store in your refrigerator for five days or it will freeze for up to six months. In human studies, increased fiber intake has been linked to a decreased risk of overweight and obesity. It’s believed that this is because fiber is filling, and most high fiber foods are lower in calories than low fiber foods like refined grains ( 27, 28). Pectin was first isolated and described in 1825 by Henri Braconnot, though the action of pectin to make jams and marmalades was known long before. To obtain well-set jams from fruits that had little or only poor quality pectin, pectin-rich fruits or their extracts were mixed into the recipe. Pectin fiber is more than just a regulator — it’s a benefit-rich fiber that’s water-soluble and helps lower cholesterol and increases digestive health.

In the UK it is called “Jam Sugar” in the US “Gelling Sugar” but both are essentially the same thing, sugar with added pectin and citric acid. Sugar, pectin and acid are all required to make jams and jellies set properly.

You can only substitute jam sugar with Splenda when the primary intention of its use is to sweeten the mix – not to preserve it. Using Low-Sugar or No-sugar PectinBefore making jam, you must first take into account if the fruit in question is high or low in pectin. Fruits low in pectin tend to be: Bidhendi, Amir J; Geitmann, Anja (January 2016). "Relating the mechanical properties of the primary plant cell wall" (PDF). Journal of Experimental Botany. 67 (2): 449–461. doi: 10.1093/jxb/erv535. PMID 26689854.

At the Joint FAO/WHO Expert Committee Report on Food Additives and in the European Union, no numerical acceptable daily intake (ADI) has been set, as pectin is considered safe. [35] You will have to adjust the individual quantities accordingly though, or you might end up with a very firm mixture that isn’t easily spreadable. Please refer to your recipe of choice for more information on the proportions of the ingredients. How To Use Jam Sugar Pectin is a fiber that is naturally found in most fruits and vegetables. Although its quantity varies, its job is the same: to hold everything together. Another study conducted at the University of Florida College of Medicine found that a grapefruit pectin-supplemented diet, without change in lifestyle, can significantly reduce plasma cholesterol. The study lasted for 16 weeks, and it involved 27 human volunteers who were screened to be at medium to high risk for coronary heart disease due to hypercholesterolemia. If you notice the sample to be runny and easy to move around with the pan then you may need to boil for 2-4 more minutes.Strain the mixture through a piece of cheesecloth. Let it sit for at least four hours (or even as long as overnight) to remove as much juice as possible from the mixture. Braidwood, Luke; Breuer, Christian; Sugimoto, Keiko (1 August 2013).

Acid is another important variable in how well your jam sets, of course, we don’t want to make the jam to acidic but by increasing the acid content slightly it can help get a better set jam.
