Candy is a kind of solid or semi-solid sweetener made from granulated sugar, powdered syrup (or other sugar) or permissible sweeteners and edible colors according to certain production process requirements. With the continuous improvement of people's living standards, the demand for the candy market is further expanding. Candy can be divided into hard candy, hard sandwich candy, milk candy, gel candy, polished candy, gum-based candy, inflatable candy, and tablet candy. Candy analysis is essential for both confectionery manufacturers to comply with FDA standards and for consumers out of safety concerns.

Techniques for biscuit testing
Colorimeter
Colorimeter is used to measure the color of candy to ensure color consistency and compliance with standards.
Texture Analyzer
Texture analyzer is used to measure the physical properties of candy such as hardness, toughness, chewiness, etc. to evaluate its taste and texture.
Moisture Meter
Moisture meter is used to determine the moisture content in candy, which is very important for the texture and preservation of candy.
Saccharimeter
Saccharimeter is used to measure the concentration or content of sugar in candy to control the sweetness of candy.
Gas Chromatograph
Gas chromatograph is used to analyze the volatile components in candy to detect its aroma and flavor.
Liquid Chromatograph
Liquid chromatograph is used to separate and analyze various ingredients in candy, such as pigments and flavors.
pH Meter
pH meter is used to determine the pH of candy to ensure that it is within the specified range.
Microscope
Microscope is used to observe the microstructure of candy, such as crystal structure and internal pores.
Solubility Meter
Solubility meter is used to measure the solubility of candy in different solvents and evaluate its dissolution behavior.
Heat Transfer Analyzer
Heat Transfer Analyzer is used to analyze the thermal properties of candies, such as melting point and thermal stability.

Determination of Sudan I-IV in Candy
Yu, W., Liu, Z., Li, Q., Zhang, H., & Yu, Y. (2015). Food chemistry, 173, 815-820.
An aqueous two-phase system (ATPS) utilizing an ionic liquid and anionic surfactant was developed for the extraction of Sudan I-IV. The analytes were quantified using high-performance liquid chromatography (HPLC). The ATPS was formed in the presence of C4[MIM]BF4, sodium dodecylbenzenesulfonate, and (NH4)2SO4. The detection limits for Sudan I, II, III, and IV were 5.45, 4.66, 3.68, and 4.20 μg kg-1, respectively. When this method was applied to the analysis of candy samples, the recoveries of the analytes ranged from 82.3% to 112.1%, with relative standard deviations of less than 7.41%.
Determination of Carmine in Milk and Candy Products
Yilmaz, U. T., Ergun, F., & Yilmaz, H. (2014). Journal of food and drug analysis, 22(3), 329-335.
As a foundation for developing a sensitive analytical method for the determination of the food dye carmine, the differential pulse polarographic reduction of carminic acid (CA) on a dropping mercury electrode was studied. For the analytical differential pulse polarography conducted in a pH 2.0 Britton-Robinson (B-R) buffer solution (with a peak at −489 mV), the peak current showed a linear relationship with CA concentration in the range of 1 μM to 90 μM, with a detection limit of 0.16 μM. The proposed electrochemical procedure has been successfully applied to the determination of carmine in commercially available strawberry-flavored milk. This method was also applied to determine citric acid (CA) in candies, yielding results that were consistent with those obtained from spectrophotometric comparison methods.
Determination of Amaranth in Soft Drinks and Candy Samples
Nguyen, T. K. T., Le, T. H. G., Pham, N. T. T., Hoang, T. H., Nguyen, H. P., Nguyen, M. X., ... & Bui, X. T. (2023). Microchemical Journal, 189, 108467.
The preparation conditions for an electrochemically reduced graphene oxide (ErGO/GCE) modified glassy carbon electrode were elucidated for the determination of amaranth in soft drink and candy samples using adsorptive stripping voltammetry. The ErGO/GCE was prepared through the electrochemical reduction of graphene oxide in the potential range of 0 V to −1.5 V using cyclic voltammetry. Amaranth is adsorbed onto the surface of the ErGO/GCE working electrode through an irreversible oxidation process. The optimal conditions for determining amaranth are a Britton-Robinson buffer solution at pH 3.0, an adsorption potential of 0 V, an adsorption time of 30 seconds, and a scan rate of 20 mV/s. The linear range for detection is from 1.0 x 10−7 mol L−1 to 1.0 x 10−6 mol L−1, with a limit of detection (LOD) of 2.8 x 10−8 mol L−1 and a limit of quantification (LOQ) of 9.3 x 10−8 mol L−1.
Why is candy testing important for manufacturers and suppliers?
Candy testing helps manufacturers verify product quality, safety, consistency, and compliance with applicable food regulations. It supports quality control throughout the production process and helps identify potential issues related to formulation, storage stability, labeling accuracy, and consumer safety.
For candy producers, reliable testing data can also support new product development, improve manufacturing processes, and provide documentation required by customers, retailers, or regulatory authorities.
How can Alfa Chemistry help ensure candy products meet regulatory requirements?
Alfa Chemistry provides analytical support to help candy manufacturers evaluate whether their products meet relevant food safety and quality requirements.
The laboratory follows established testing procedures and can help companies generate reliable analytical data for:
Testing strategies can be customized according to the target market, product characteristics, and customer requirements.
When should candy products be tested during the manufacturing process?
Candy testing can be performed at different stages depending on the purpose of evaluation.
Common situations where testing support is needed include:
Regular analytical verification helps manufacturers maintain consistent quality and reduce potential quality risks.
How does Alfa Chemistry ensure the accuracy and reliability of candy testing results?
