Soft candies are popular confectionery products. The most significant concern on the consumption of these products is the high amount of sugar and thus the high calories. The use of low-calorie sweeteners is a desirable trend in confectionery research. In this study, gelatin-based soft candies were formulated by using different sweeteners and their characterisation was performed using high and low field nuclear magnetic resonance (NMR) relaxation experiments. To complement the information obtained by NMR experiments, moisture content, water activity, texture analysis and differential scanning calorimeter experiments were also conducted. T-1 and T-2 relaxation times were measured at both low and high fields and also temperature-dependent measurements were conducted at the high field system. Candies were formulated by substitution of sucrose with maltitol, isomalt and stevia at 30%, 50% and 70% ratios. Significant difference was observed on relaxation times. T-1 values were best described by a mono-exponential model, whereas for T-2 relaxation times a bi-exponential model gave better results at both fields.

Investigation of Physical Properties and Moisture Sorption Behaviour of Different MArshmallow Formulations Kırtıl, Emrah; Öztop, Halil Mecit (2016-08-25) Marshmallows are a type of confectionary product known for its soft, foamy texture. It owes this characteristic to its relatively high moisture content (17-21% by wt) and porous structure. However, these attributes make marshmallows more susceptible to quality degrading changes such as; sugar crystallization, texture aging, foam collapse and hardening or softening. The high interfacial area, increases the rates of mass transfer which makes it harder for marshmallows to preserve its initial moisture content ...
In vitro digestibility of rare sugar (D-allulose) added pectin-soy protein gels Ateş, Elif Gökçen; Ozvural, Emin Burcin; Oztop, Mecit H. (2021-04-01) Confectionery gels are known to be high-caloric products due their high sugar content. Changing their formulations by substituting the sugar with alternative natural sweeteners and functionalising them, the addition of proteins has gained attention. Understanding the rate of digestion of these products is also important for selecting the appropriate formulation. In this study, in vitro gastric digestion behaviour of the gels formulated with D-allulose, a low-calorie rare sugar, soy protein isolate (SPI) (1%...
In vitro digestibility of soy-protein isolate containing soft candies formulated with d-psicose Sakar, Elif Gökçen; Öztop, Halil Mecit; Department of Food Engineering (2019) Commercial soft candy products are known to contain high amount of sugar and therefore they are considered as not healthy and high calorie sweets. Most of the candy present in the market are made by sucrose and as a gelling agent, gelatin and sometimes starch or pectin is being used. In this study, D-Allulose (rare sugar), soy protein isolate (SPI) and pectin were used to prepare different soft candy formulations. D-Allulose was used as a replacement of sucrose at different ratios (Sucrose/D-Allulose: 0/35,...
Bioconversion of Alkali Pretreated Hazelnut Shells to Fermentable Sugars for Generation of High Value Products Uzuner, Sibel; Shivappa, Ratna Rani Sharma; Çekmecelioğlu, Deniz (2017-03-01) Hazelnut shells are lignocellulosic by-products of hazelnut processing. As the shells are rich in cellulose and hemicellulose, they have high potential as a raw material for production of food enzymes, biofuel, and various chemicals (acetic acid, furfural and lignin degradation products) after bioprocessing. The objective of this study was to determine the effect of alkali pretreatment and enzymatic hydrolysis on production of fermentable sugars from hazelnut shells. The hazelnut shells were pretreated with...
Characterization of curcumin incorporated guar gum/orange oil antimicrobial emulsion films Aydogdu, Ayca; Radke, Clayton J.; Bezci, Semih; Kırtıl, Emrah (Elsevier BV, 2020-04-01) Edible films are manufactured from natural, renewable, nontoxic, and biodegradable polymers and are safe alternatives to plastic food packaging. Despite ongoing research, biopolymer-based edible films still are not at a quality to ensure total commercial replacement of synthetic packaging materials. The study aims to compare the effectiveness of some novel methods employed to improve edible film properties. These include dispersion of orange oil (1% & 2% v/v) and/or curcumin into guar gum (GG), glycerol and...
