Pickling is a process of preserving foods in: Correct Answer Vinegar and salt

Concept-

  • Food preservation is a process by which we prevent the spoilage of food such as fruits and vegetables.
  • Spoilage of food is due to microbial growth.
  • Through food, preservation one can increase the life of the food and can store it for a long time.
  • Food preservation plays an important role in people's businesses.
  • The most commonly used preservative includes table salt, sugar, vegetable oils, etc.

Explanation-

  • Pickling is the process of preserving food by different methods.
  • Pickling can add a flavor to food by itself.
  • The food is called pickle.
  • There are two basic types of pickling done-
    • The first one includes food preserved in vinegar, an acid.
    • The second one is a brine solution.
  • Brine is an aqueous solution of NaCl (Salt).

Thereby pickling is a process of preserving foods in vinegar and salt.

Additional Information

Brine

  • The Brine is the solution of salt (NaCl) and water. 
  • They occur naturally on the Earth’s surface in salt lakes or even the benthic zone of the oceans.
  • They occur due to the evaporation of ground saline leaving behind little water with a high concentration of Sodium Chloride.
  • Applications include meatpacking, pickling, steel quenching, heat-transfer medium.

Vinegar

  • Vinegar is a sour liquid that is made by the fermentation of numerous dilute alcoholic liquids into a liquid containing acetic acid.
  • Vinegar can be made from any liquid that is capable of being converted into alcohol in a two-step process. 
  • Because of its acetic acid content and low pH, vinegar is used as a preservative for both domestic use and in the food industry. 
  • It is used for the preservation, or pickling, of a wide variety of foods such as vegetables, meat, fish products, and spiced fruits. 
  • Floral vinegar is an easy way to preserve the vibrant flavors and aromas of edible flowers.
  • Vinegar adds an acidic taste and helps to balance flavor in recipes.

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?

The following items consist of two statements, one labeled as “Assertion (A)” and the other labeled as the “Reason (R)”. You are to examine the two statements carefully and decide if the Assertion (A) and the Reason (R) are individually true and if so whether the reason is a correct explanation of the assertion. Select your answer to these items using the codes given below and mark your answer accordingly. Assertion (A): Polarization preserving fibers have a special core design that maintains the state of polarization. Reason (R): In polarization preserving fibers, there is a stress applying part, which creates slow and fast axes in the core.
