Jaggery (Gur): Manufacturing of Jaggery Jaggery is from sugar cane c ane followed followed by clarification and concentration process. It is Uncentrifuged sugar (i.e Without separation of molasses) with minimum sucrose 70 to 80% by mass. It is also called as Gur.
Flow Chart for Jaggery Making Process:
Main steps in jaggery making process: Extraction of Juice
Extraction of Juice: Generally Gene rally three roller roller mills m ills used us ed for juice extraction. extract ion. It It is driven by electric electrical al motor or diesel engine. engine. This
extraction of juice is in the range of 60 to 70%. After extraction of juice, suspended matters are removed by cotton cloth or finr mesh screen.
Clarificationn of juice: Clarificatio The sugar juice contains colloidal matter, inorganic salts, fiber, various nitrogenous substances, lipids, gums, wax organic acid, inorganic acid, pectin etc. All these impurities removed totally or partially in this clarification process. In the clarification clarification process generally used two types of clarificants are used they are Organic Clarificants and In n organic clarificants are form vegetable origin like Bendi, Sulkali and Doela. Inorganic Inorganic Clarificants. I clarificants used like Lime, Hydrous Power and super phosphate . The screen juice taken in open pan and firing starts slowly so that dissolved air escaped and gummy, colloidal
substances get coagulated by the adding of clarificants as per requirement. It comes at top surface of the juice know as scum and it is removing continuously . In In this process temp temperature erature requirement is 70oC to 800 First added vegetabl vegetable e origin simultaneously sm all quantity quantity of lime water is added to reduce the acidity of juice but not to the extent to make m ake juice neutrals because taste and colour c olour of gur produced will be inferior. In this lime c ases super phosphate. P 2O5, and 0.25% concentrated process pH maintained 6.2 to 6.5. In some cases
hydrous power are also added to obtain good colour of Gur (jaggey). While juice temperature rising scum is removed by perforated strainers.
Concentration of juice:
or Bucket shape boxes as per requirement. This mass is allowed to cool for solid form.
Composition and specification of Jaggery (Gur) : It contains all the nutrients and substances s ubstances present in cane c ane juice. The nutrient value of jaggery jaggery is s lightly higher higher than that of crystalline sugar because it contains all constituents which are normally separated in molasses in manufacturing of sugar. Recovery of jaggery in the range from 8 to 12% that depending upon the total solids in cane. Jaggery graded in the market according to basis of colour, taste, hardness and crystalinity which is judged by visual appearance. While in practically graded of jaggery should be consider sucrose %, reducing sugar, moisture and colour.

Storage of jaggery: Jaggery is consumed throughout the year in daily regular practice. The jaggery detoriates faster in monsoon season when rela relative tive humid humidity ity is more than than 70%. 70%. During During this this season gur absorbs absorbs moisture from the atmosphe atmosphere re and and becomes becomes viscous and dark colour. Hence jaggery jaggery blocks packed in gunny bags bags along with water w ater proof sheet.
Organic Jaggery making Process: Process : In Manufacturing of organic Jaggery taking care from fr om growing of sugar cane . In sugar cane cultivation maximum used only natural organic organic fertilizers f ertilizers like cow dung. The d The difference ifference between between organic and com commerc mercial ial jagge jaggery ry making making is mainly in clarification process. In organic
jaggery jagg ery makin making g process process used only organic clarificants and little bit of lime to decrease the acidity of juice. So
