Q. Which of the following law gives the relationship between the moles of water and the moles of solute in a solution and its water activity?

View solution

Q. Rice has a higher water activity than apples.

View solution

Q. As the moisture content of a food decreases, a restraint is observed on the vapor pressure which is evident from the water activity.

View solution

Q. Statement 1: When there is an equilibrium between the vapor pressure and the percentage relative humidity, water activity is directly proportional to the percentage relative humidity.
Statement 2: Even a water activity as high as 0.85 for food items is considered to be very dry for substances.

Q. Which of the following is true when a solute is added to water?

View solution

Q. Statement 1: Sodium chloride has a higher water activity than sucrose.
Statement 2: Sucrose creates structures in water and reduces water activity below what they should be based on concentration alone.

View solution

Q. Statement 1: Just like the vapor pressure on an individual component is higher than when it is in bulk, the water activity is low when in bulk.
Statement 2: Water activity is directly proportional to the surface tension and molecular weight of water and inversely proportional to density of water.

Q. If a dehydrated porous absorptive food is soaked in a solution whose viscosity is not too high to penetrate, then the food will absorb an amount of solution approximately equal to the amount of water it would normally absorb.

Q. Semi moist food items work on the principle that the additives will diffuse into the food to an extent that the final concentration in the food and in the solution will be similar.

View solution

Q. Semi moist food items work on the principle of equilibrium, that is at a dry state, the food items absorb the solution and in the wet state, water is washed out with another liquid by diffusion.
