Current production strategies and sustainable approaches towards the resurgence of non-centrifugal cane sugar production - a review

Non-centrifugal cane sugar (NCS) is a traditional unrefined sweetener widely consumed across the globe, in different forms and under different names. Unlike refined sugar which possesses only carbohydrates and negligible health impacts, NCS is healthier and more nutritious as it contains minerals, vitamins and phenolic antioxidants. A shift in consuming patterns focussing on health aspects has opened an opportunity for natural sweeteners such as NCS in the global market, but they are hampered by bottlenecks such as improper final product quality, inefficient production techniques and unauthorized use of chemicals. Considering the status quo of NCS production, this review initially focuses on conventional NCS production methods and their drawbacks. Later, the review session moves into a discussion related to documented scientific interventions and technological advancements in improving the efficiency of NCS production. Finally, recommendations and strategic hygienic policies for the modernization of the NCS industry are discussed. Revival of NCS production requires energy-efficient machinery and technologies. Modern packaging techniques such as modified atmospheric packaging, vacuum packaging, and edible coating can enhance the shelf-life of NCS. Strict implementation of food standards for NCS will aid in preventing adulteration. The revival of NCS manufacturing units can provide employment opportunities, mainly for the rural population. Besides, an increase in NCS production can establish its potential as an alternative to refined sugar. Demand for non-centrifugal sugars (NCS) is hampered by bottlenecks such as improper flow and unhygienic production practices. In this review, we discuss various advances and strategies required for the resurgence of NCS in the global market.
