Dried glucose syrup is commonly used in a wide range of food and beverage applications. In the food industry, it is used in confectionery, bakery products, snacks, and processed foods to provide sweetness, texture, and preservation benefits. It is particularly useful in products like candies, bakery items, and frozen foods, where it prevents crystallization and enhances shelf life. In the beverage industry, it is used in soft drinks, energy drinks, and fruit juices to provide sweetness, improve mouthfeel, and prevent crystallization, making it a key ingredient in sugar-free or low-sugar drinks. Additionally, it is used in dairy products, such as ice cream and milk powder, to improve consistency and prevent sandiness in frozen dairy products[3][2].
The production of dried glucose syrup involves several key steps, starting with the preparation of the raw material. Traditionally, glucose syrup is produced from starch derived from crops such as corn, rice, cassava, or potatoes. The process begins with mixing the starch with water to create a starch slurry. This slurry is then subjected to a liquefaction process, where high-temperature resistant enzymes (α-amylase) are added, and the mixture is heated to around 100-108°C using a jet cooker to break down the starch into a more manageable viscosity[1][2][3].
Following liquefaction, the slurry undergoes several additional processes: deproteinization to remove proteins, saccharification to convert the liquefied starch into glucose using saccharifying enzymes, decolorization to remove impurities, decarburization to remove activated carbon, and an ion exchange process to eliminate ion impurities. After these steps, the syrup is evaporated using a multi-effect evaporator to achieve the desired concentration. Finally, the concentrated glucose syrup can be dried to produce dried glucose syrup, often in the form of solid granules. This dried form is convenient for storage and transportation, and it can be easily reconstituted when needed[1][2][3].
The safety profile for human consumption of Dried Glucose Syrup is largely centered around its high sugar and calorie content, which can have significant health implications when consumed excessively. Regular consumption of glucose syrup is associated with increased risks of heart disease, higher blood pressure, dental decay, poor dental health, elevated blood sugar levels, and obesity. While allergic reactions to glucose syrups are rare, some individuals may experience symptoms such as skin peeling, blisters, swelling, and respiratory issues. It is advisable to consult a healthcare professional before using glucose syrups, especially for individuals with diabetes or poor sugar tolerance. Health authorities recommend limiting daily intake of added sugars, including those from glucose syrups, to 25-30 grams per day to minimize health risks[1][2].
Regarding potential contamination risks, Dried Glucose Syrup is generally considered to have a low risk of pathogen contamination. Studies have shown that liquid sweeteners, including those similar to glucose syrup, are not conducive to the survival of microbial pathogens such as Salmonella, Listeria, and Staphylococcus aureus, as these microorganisms typically decline to undetectable levels within a few days when stored at normal temperatures[3]. There is no significant evidence to suggest that Dried Glucose Syrup is particularly prone to heavy metal contamination or heavy pesticide use in its production. However, as with any agricultural product, there could be residual risks depending on the farming practices and environmental conditions where the raw materials are sourced. Nonetheless, these risks are not unique to glucose syrup and are generally managed through regulatory oversight and good manufacturing practices[1][3].
