Explanation

Louis Pasteur developed pasteurization, but Nicolas Appert discovered the principle of canning (preserving food in sealed containers), which is a form of sterilization. However, 'Pasteurization' is often incorrectly attributed to him in some contexts, but strictly speaking, Appert's work led to canning. Wait, let me double-check. Appert is known as the father of canning. The principle he discovered is preserving food by heating it in sealed containers. This process is sterilization (specifically, commercial sterilization or pasteurization depending on the temperature, but canning aims for sterilization). However, many sources say Appert discovered the principle of 'canning' or 'preservation'. Let's look at the options: A: Pasteurization, B: Sterilization, C: Tining (Typo for Tin?), D: Browning. Appert's work is the foundation of canning. Canning involves sterilization to kill microbes. Pasteurization is associated with Pasteur. So B is likely correct in this context. Actually, some quizzes link Appert to 'Pasteurization' erroneously, but scientifically, Appert used heat treatment which is pasteurization-like, but the goal was preservation via sealing. The standard answer for Appet's discovery in food tech MCQs is often 'Canning' or 'Preservation'. If 'Canning' isn't an option, 'Sterilization' is the closest technical principle. However, sometimes 'Pasteurization' is the distractor. Let's check common MCQ banks. Question:
