Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Asepsis is a fundamental concept in food preservation and microbiology.
It refers to the practice of maintaining sterile conditions by preventing the entry and establishment of microorganisms in a clean environment or food product.
Step 2: Detailed Explanation:
Let us analyze the biological definition of asepsis:
- The word "Asepsis" literally translates to "without sepsis" or the absence of contamination.
- In food technology, it refers to the process of keeping microorganisms out of the food matrix.
- This is achieved using protective packaging (such as canning, vacuum sealing, or aseptic packaging), sanitizing tools, and working in sterile environments.
Let us evaluate why the other options are incorrect:
- Option (A): Describes thermal sterilization (bactericidal action), which kills existing microorganisms rather than preventing their entry.
- Option (C): Describes filtration (clarification), which physically removes present microbes, but does not define the barrier action of asepsis.
- Option (D): Freezing is a low-temperature preservation method (biostatic), not a sterile barrier technique.
Therefore, keeping microorganisms from entering the food is the correct definition of asepsis.
Step 3: Final Answer:
Asepsis is defined as keeping microorganisms out from entering into food.
