Question

Write a few sentences or paragraphs about saccharin sweetener answering the following:

1. sweetness level (compared to sugar)

2. stability (hot or cold)

Answer 1

Ans) 1)

Saccharides have varying degrees of sweetness on a relative scale as illustrated in the table on the left. Fructose is the sweetest, while lactose is only slightly sweet by comparison.

Relative Sweetness Scale - Sucrose = 100

Compound Rating

Galactose 35

Maltose 30-50

Lactose 20

- Scientists can measure relative sweetness by comparing the threshold values for various types of sugar and sugar substitutes. Sucrose, or table sugar, is the taste that every artificial sweetener tries to mimic.

2) In the minds of people 'cold' should be more stable. But, paleo data show that it is 'cold' that is unstable. While 'warm' always shows a high stability in climatic conditions.

- Fluid temperature stability is essential to the success of mechanical systems. All hydraulic and lubricating fluids have practical limits on the acceptable operating temperature range - both high and low levels.

-

Lubricant Temperature Stability
The machine loses stability and experiences conditional failure whenever the system’s fluid temperature violates these limits. If left unabated, the conditional failure ultimately results in both material and performance degradation of machine components.

Temperature extremes have a pronounced effect on component materials as well as machine performance. When temperature is too low, fluid viscosity is high.

At low temperatures, the fluid often reaches the point where it actually congeals and will no longer flow (pour point). High temperature also accelerates wear, destroys hydrodynamic lubrication regimes, increases the oxidation rate, fosters additive depletion and affects other critical aspects of the machine.

Fluid temperature instability is the result of various machine operating factors such as component integrity (design, selection, manufacture, application and maintenance), duty cycle severity (load application, magnitude and duration), environmental hostility and heat absorption/desorption.

Operation and maintenance personnel should thoroughly investigate an occurrence of temperature instability to understand the effects on machine operation in order to optimize its performance and prolong equipment service life
