Are these statements about the D value true? Statement 1: D -value is lower in acid foods. Statement 2: D-value for the same organism varies depending on the food type.

Are these statements about the D value true? Statement 1: D -value is lower in acid foods. Statement 2: D-value for the same organism varies depending on the food type. Correct Answer True, True

D value is defined as the time taken at a given temperature to eliminate at least 90% of the exposed microorganisms. It is suitable to examine the efficiency of thermal inactivation of different microbes under different conditions. D-value for the same microbes differs depending on the food type. In acid foods, the D value is lower and higher in protein rich foods.

In a batch process, the reaction takes place in the presence of an acid medium. The acid is drained from the reaction vessel at the rate of 15ml/s as a result of the density difference of the acid from the reacting component. To avoid wastage of acid, it is recycled to an acid tank which has 1000 L capacity. The acid drained from the reaction vessel, picks up 50 g/L solids from the reactor. Acid is fed once again to the process from acid tank. When the process is started, the acid is almost pure in the tank as a result of filtration. As the reaction proceeds, acid in the tank gets more and more contaminated with the solids. The concentration of the solids should not exceed 100 g/L from the process point of view. The batch time is 16h. Estimate whether the concentration of the solids will exceed 100g/L during the batch reaction.

Read the passage carefully and choose the best answer to each question out of the four alternatives and click the button corresponding to it. It's nothing short of a revolution in how we eat, and it's getting closer every day. Yes, a lot of people are obese, and yes, the definition of "healthy eating" seems to change all the time. But in labs and research centres around the world, scientists are racing to match our genes and our taste buds, creating the perfect diet for each of us, a diet that will fight disease, increase longevity, boost physical and mental performance, and taste great to boot. As food scientist J.Bruce German says, "The foods we like the most will be the most healthy for us." Is that going to be a great day, or what? All this will come to pass, thanks to genomics, the science that maps and describes an individual's genetic code. In the future, personalized DNA chips will allow us to assess our own inherited predispositions for certain diseases, then adjust our diets accordingly. So, if you're at risk for heart disease, you won't just go on a generic low-fat diet. You'll eat foods with just the right amount and type of fat that's best for you. You'll even be able to track your metabolism day-to-day to determine what foods you should eat at any given time, for any given activity. "Since people differ in their genetics and metabolism, one diet won't fit all," says German. As complex as all this sounds, it could turn out to be relatively simple. What are scientists doing?
