Development of Galactooligosaccharide (GOS) added gummies: sensory, characterization and shelf quality

Abstract

Sugar loaded confectioneries have a rapidly growing market globally. Consumption of such products may lead to multiple health risks. Products like gummies can be substituted with healthy sugar alternatives such as Galactooligosaccharide (GOS), which can be consumed by all age groups.The aim of the study was to develop standard gummies and sugar substituted gummies, conduct sensory analysis, shelf life studies and characterize it for its physico chemical properties.The standard gummies were made using agar, sugar, citric acid, water, and FSSAI (Food Safety Standards Authority of India) certified natural colours and flavours, while GOS supplemented gummies were made by replacing sugar in varied amounts, upto 100%. A trained panel (n = 8) evaluated the gummies using a composite score card in triplicates for a variety of sensory attributes. GOS recovery analysis, physicochemical variables such as colour, moisture, pH, and texture were assessed. Shelf life Studies of 100 percent GOS supplemented gummies were carried out at accelerated temperatures (37 °C) over a period of 6 months.The results revealed that gummies with varying levels of GOS were acceptable to the panelists, with no significant differences in the keeping quality. However, F test revealed a significant improvement (p < 0.05) in the texture of the gummies with a slight reduction in colour and flavour at the end of 6 months. The moisture content and pH values were 24.8% and 3.37 respectively. HPLC analysis revealed a recovery of 95% GOS in the prepared gummies.Hence, sugar can be substituted with 100% GOS to fulfil the increasing demand for healthy confectioneries without any change in organoleptic qualities and shelf life for 6 months.Graphical
