Crystal of aspartame sweetener, SEM

Aspartame crystal. Coloured scanning electron micrograph (SEM) of a crystal of the artificial sweetener aspartame. This chemical is nearly 200 times sweeter than sugar but has a very low calorific value. It is used to sweeten foods and soft drinks, and is used by diabetics as a sugar substitute. Aspartame contains phenylalanine, so products must carry a warning as people with the disease phenylketonuria (PKU) are unable to metabolise this amino acid. Alleged connections of aspartame consumption with brain lesions, tumours and lymphoma have made the chemical the centre of a public controversy. Magnification: x86 when printed 10 centimetres wide

Artificial Aspartame Controversial Controversy Crystal Food Additive Food Stuff Foods Foodstuffs Nutrasweet Phenylalanine Sweetener False Coloured

EDITORS COMMENTS
This print showcases a crystal of the artificial sweetener aspartame, captured using a scanning electron microscope. Aspartame is renowned for its intense sweetness, being nearly 200 times sweeter than sugar, while having minimal calories. It is widely utilized to add sweetness to various foods and soft drinks, serving as an ideal sugar substitute for individuals with diabetes. However, this seemingly harmless chemical has not been without controversy. Aspartame contains phenylalanine, which poses a significant risk to those suffering from phenylketonuria (PKU), a metabolic disorder that hinders the breakdown of this amino acid. Consequently, products containing aspartame must carry warnings to protect individuals with PKU. Moreover, alleged connections between aspartame consumption and brain lesions, tumors, and lymphoma have sparked public debate surrounding its safety. This controversy has thrust the chemical into the spotlight and prompted further research on its potential health effects. The false-colored image reveals intricate details of the crystal structure at an impressive magnification of x86 when printed at 10 centimeters wide. Its vibrant hues draw attention to both the beauty and complexity found within this controversial food additive. Overall, this visually stunning photograph encapsulates both the allure and contentious nature of aspartame – a powerful sweetener that continues to be scrutinized by scientists and consumers alike.
