Takeaways

• 😀 Additives and addictive substances are often used in food to enhance appearance, taste, and shelf life.
• 😀 Food colors can be natural (from plants) or artificial, with examples like beetroot for red and turmeric for yellow.
• 😀 Natural sweeteners like sugar and palm sugar are used in food, but artificial sweeteners such as cyclamate and aspartame are much sweeter.
• 😀 Flavor enhancers such as salt, garlic, and MSG are used to make food taste savory or umami.
• 😀 Natural aromas come from fruits, essential oils, and vanilla, while artificial scents like amyl acetate are used for fruit-flavored products.
• 😀 Thickeners such as starch, gelatin, and agar-agar are added to food to create desired textures without altering taste.
• 😀 Emulsifiers like lecithin from egg yolks are used to stabilize mixtures of water and oil in products like butter and mayonnaise.
• 😀 Preservatives, such as salt in salted fish or sugar in fruit preserves, help food stay fresh longer, with artificial preservatives like benzoic acid also commonly used.
• 😀 Additives are safe in moderation, but excessive consumption can be harmful and lead to health issues.
• 😀 Addictive substances, including narcotics, psychotropics, and psychoactive substances like caffeine and nicotine, can cause dependency and health risks if abused.

Q & A

What are additives, and what role do they play in food?

Additives are substances added to food or beverages to improve their color, flavor, texture, shelf life, or stability. Common additives include colors, sweeteners, preservatives, flavor enhancers, thickeners, and emulsifiers.

What are some natural and artificial coloring agents used in food?

Natural coloring agents come from plants, such as beetroot for red, turmeric for yellow, and pandan leaves for green. Artificial coloring agents, like Allura Red and Tartrazine, are used for their strong and cost-effective coloring properties.

What are the differences between natural and artificial sweeteners?

Natural sweeteners include sugar (like cane sugar and palm sugar), while artificial sweeteners are man-made substances such as cyclamate, aspartame, and saccharin, which are much sweeter than natural sugar.

What is MSG, and how does it affect food?

MSG (monosodium glutamate) is a flavor enhancer that adds a savory umami taste to food. It is a synthetic compound that enhances the flavor of foods, especially savory dishes.

What are emulsifiers, and why are they important in food?

Emulsifiers are substances that help mix ingredients that do not naturally combine, like oil and water. Examples include lecithin found in egg yolks. They are essential in products like mayonnaise and butter to maintain consistency and prevent separation.

Why are preservatives added to food, and what are some examples?

Preservatives are added to extend the shelf life of food by preventing spoilage from microorganisms. Examples include salt in salted fish, sugar in candied fruit, and chemical preservatives like benzoic acid and ascorbic acid in packaged foods.

What are the potential risks of consuming excessive additives?

Excessive consumption of additives can lead to health issues like allergic reactions, digestive problems, or long-term effects such as organ damage and cancer. It is important to consume additives within safe limits.

What is the difference between addictive substances and additives?

Addictive substances, like narcotics and psychoactive drugs, can lead to dependence and have psychological effects. Additives, on the other hand, are used to enhance the characteristics of food without causing addiction.

What are narcotics, and how are they classified?

Narcotics are substances that alter consciousness, reduce pain, and can cause dependence. They are classified into three groups: Group I (high potential for abuse, like heroin), Group II (high potential, but limited medical use, like morphine), and Group III (low potential, like codeine).

How do stimulants and depressants affect the body?

Stimulants, like caffeine and methamphetamine, increase the activity of the central nervous system, enhancing alertness. Depressants, like alcohol and diazepam, slow down the nervous system and can lead to sedation or drowsiness.
