Definition of Food Additives
A substance added to food to preserve or enhance the taste and appearance of the food.
 
The image is an infographic about food additives. It features a central icon of a lightbulb with a checkmark inside, symbolizing ideas or knowledge. Surrounding the lightbulb are five categories of food additives, each in a blue box with a number and description. The categories are: 1. Preservatives 2. Antioxidant 3. Flavouring 4. Stabiliser and thickening agent 5. Colouring Arrows connect the categories in a circular flow, indicating their relationship or cycle. The background is white, and the text is in blue. The Pandai logo is in the top left corner.

Bad Effects of Food Additives When Taken Excessively

The image is a diagram illustrating the bad effects of food additives when taken excessively. At the center, there is a blue circle with the text ‘Bad Effects of Food Additives When Taken Excessively.’ Four arrows point outward from the central circle to four smaller circles. The smaller circles contain the following text: ‘Allergies,’ ‘Cancer,’ ‘Nerve disorder,’ and ‘Asthma, rashes and hyperactivity in children.’ The background is white, and the diagram is simple and clear. The logo ‘Pandai’ is at the bottom center.
