CD BioGlyco's caramel analysis service offers a comprehensive and customized solution for assessing the safety and quality of caramel samples. We ensure that our results of Pharmaceutical Excipient samples are accurate through diverse advanced analysis approaches. Caramel is primarily derived from carbohydrates such as sucrose or glucose through heating processes. It is a dark brown viscous liquid or dark brown powder with a slight peculiar odor. Caramels are soluble in water and form a homogeneous mixture. It dissolves in ethanol with a concentration of less than 55% (v/v) but is insoluble in ether, chloroform, acetone, benzene, or n-hexane.
We will dilute the sample with water, add phosphoric acid, and ensure thorough mixing. Ideally, there should be no formation of precipitate.
The sample will be dissolved in water to prepare a solution, ensuring thorough dilution. We utilize (ultraviolet) UV-visible spectrophotometry to measure the absorbance at 610 nm wavelength.
Concerns are raised about the possible formation of 4 dimethylimidazole during caramel production. Due to its carcinogenic potential, the use of caramels is being investigated. The risk of cancer could be increased by exposing consumers to the 4-methylimidazole. Therefore, we will analyze the presence of 4-methylimidazole in caramel and determine the content of 4-methylimidazole by high-performance liquid chromatography (HPLC). By this analysis, we provide accurate data for this important parameter.
Ammonia nitrogen, an important test item, will be detected by using the titration method. We will place the sample in a distillation flask containing magnesium oxide and water. Then, recover the distillates into a boric acid solution. The ammonia nitrogen content is determined by titrating the distillate with hydrochloric acid and measuring the absorbance.
We will detect sulfur dioxide by quantifying its presence in a sample through a titration process using sodium hydroxide. Through the method, the concentration of sulfur dioxide is assessed in the sample accurately.
The ash content will be determined by grinding the sample, mixing it well, and then taking a portion. We will place it into a crucible, heat it gradually to a high temperature until it completes ashing, and calculate the ash content based on the residual weight.
For the detection of arsenic salts, we use the Gutzeit method and the dithizone method. We will achieve a complete detection of arsenic with the combination of these two methods. The Gutzeit method provides sensitivity for trace levels, while the dithizone method offers specificity and efficiency in screening. In this dual approach, the detection of arsenic salts in a wide range of concentrations is guaranteed to be reliable and accurate.

Results: This study examines glucose caramelization reactions in a water system, focusing on the characterization of glucose caramel products (GCPs) at different reaction phases. The authors examined the properties of GCPs, including reaction rates, UV absorption, flavor compounds, and antioxidant and antibacterial activity, produced at different temperatures and reaction times. The results showed that a stable glucose response rate of approximately 80% was observed in GCPs produced at 180°C for four minutes. UV absorption of GCPs at 305 nm followed an exponential order, with GCPs produced at 180°C for 4 minutes exhibiting the highest concentration of main flavor compounds, as well as potent antioxidant and antibacterial activities. Due to their antioxidant and antibacterial properties, these caramel products hold potential applications within the food industry.
