Decoding corn syrup: its presence in new zealand and its implications

Corn syrup, a ubiquitous ingredient in processed foods, is a sweetener derived from cornstarch. In New Zealand, it is commonly used in the production of confectionery, baked goods, and beverages. Corn syrup is a type of simple sugar that consists of glucose, fructose, and maltose. It is sweeter than sucrose (table sugar) and has a lower freezing point, making it an ideal ingredient for products that require a high level of sweetness and a longer shelf life.

Types of Corn Syrup

There are various grades of corn syrup available in New Zealand, each with its unique characteristics:

• Light corn syrup: This is the most common type of corn syrup, with a high glucose content and a relatively low viscosity. It is often used in baking and confectionery.
• Dark corn syrup: This type has a higher viscosity and a darker color due to the presence of caramel. It is commonly used in sauces, glazes, and baked goods.
• High-fructose corn syrup (HFCS): HFCS is a sweeter and less expensive alternative to sucrose. It is produced by adding fructose to corn syrup, resulting in a higher fructose content.

Production of Corn Syrup

Corn syrup is produced through a multi-step process:

1. Milling: Corn kernels are ground into a fine powder.
2. Steeping: The corn powder is mixed with water and heated to extract the starch.
3. Liquefaction: The starch is broken down into glucose using enzymes.
4. Saccharification: The glucose is further broken down into fructose and maltose using additional enzymes.
5. Filtration: The syrup is filtered to remove impurities.
6. Evaporation: The syrup is concentrated through evaporation, removing excess water.

Uses of Corn Syrup in New Zealand

Corn syrup is widely used in New Zealand’s food industry:

• Confectionery: Corn syrup is a key ingredient in candy, chocolate, and other confectionery products.
• Baked goods: It is used to add sweetness and moisture to cakes, cookies, and bread.
• Beverages: Corn syrup is commonly used as a sweetener in soft drinks, fruit juices, and energy drinks.
• Sauces and glazes: It is used to thicken and sweeten sauces, glazes, and marinades.

Health Implications of Corn Syrup

While corn syrup can enhance the flavor and shelf life of processed foods, it has been linked to several health concerns:

• Weight gain and obesity: Corn syrup is high in calories and fructose, which can contribute to weight gain and obesity.
• Dental decay: The high sugar content of corn syrup can promote tooth decay.
• Chronic diseases: Studies have suggested a link between high corn syrup consumption and an increased risk of developing chronic diseases such as type 2 diabetes and heart disease.

Alternatives to Corn Syrup

There are several natural and artificial sweeteners that can be used as alternatives to corn syrup:

• Honey: Honey is a natural sweetener with a lower glycemic index than corn syrup.
• Maple syrup: Maple syrup is another natural sweetener derived from the sap of maple trees.
• Agave nectar: Agave nectar is a low-glycemic sweetener extracted from the agave plant.
• Sucralose: Sucralose is an artificial sweetener that is sweeter than sugar but contains no calories.
• Stevia: Stevia is a natural sweetener derived from the stevia plant, which is much sweeter than sugar.

Choosing Healthier Options

When selecting processed foods, it is important to consider the amount of corn syrup they contain. If possible, opt for products with reduced or no added sugars. Natural sweeteners, such as honey or maple syrup, can provide a healthier alternative to corn syrup.

Common Questions and Answers

Q: Is corn syrup banned in New Zealand?
A: No, corn syrup is not banned in New Zealand. However, there are regulations in place to ensure that it is labeled accurately on food products.
