Arrange P, Q, R, S, between A & B to give the correct sequence of a story.

A: "This discovery is important to food scientists and candy lovers because it will give them yummier caramel flavours and more tantalizing textures. It even gives the pharmaceutical industry a way to improve excipients, the proverbial spoonful of sugar that helps your medicine go down/' said Shelly J. Schmidt, a University of Illinois professor of food chemistry.

P: Schmidt and graduate student Joo Won Lee didn't intend to turn an established rule of food science on its head. But they began to suspect that something was amiss when they couldn't get a constant melting point for sucrose in the work that they were doing.

Q: In a presentation to the Institute of Food Technologists about the importance of the new discovery, Schmidt told the food scientists that they could use the new findings to manipulate sugar and improve their products' flavour and consistency.

R: "Certain flavour compounds give you a nice caramel flavour, whereas others give you a burnt or bitter taste. Food scientists will now be able to make more of the desirable flavorus because they won't have to heat to a 'melting' temperature but can instead hold sugar over a low temperature for a longer period of time/' she said.

S: Candy makers will be able to use a predictable time-temperature relationship, as the dairy industry does in milk pasteurization, to achieve better results, she said.

B: The scientists determined that the melting point of sugar was heating-rate dependent.
