1. Which of the following is a small spherical particle with the size varying between 50nm to 2mm, which contains a core substance?

Explanation

A microcapsule is a small spherical particle that contains a core substance. It has a size that can vary between 50nm to 2mm. Unlike vacuoles, which are membrane-bound organelles found in cells, microcapsules are synthetic particles. Droplets and shells are also not the correct answers as they do not specifically refer to small spherical particles with a core substance.

2. Which of the following does the technique of microencapsulation depend on?

Explanation

Microencapsulation is a technique that involves enclosing small particles or droplets of a material within a protective coating. The success of this technique depends on the chemical properties of the material being encapsulated. These properties determine the compatibility of the material with the coating material and the ability of the coating to effectively encapsulate and protect the material. Factors such as solubility, reactivity, and stability of the material play a crucial role in determining the suitability of the material for microencapsulation.

3. Which of these is not a step involved in Coacervation-phase separation technique?

Explanation

Coacervation-phase separation technique involves the formation of three immiscible chemical phases, coat deposition, and coat rigidization. However, evaporation of the solvent from the matrix material is not a step involved in this technique.

Submit
4. Which of these is odd regarding the methods used in manufacturing microcapsules? 

Explanation

Coarcervation-Phase Separation is odd regarding the methods used in manufacturing microcapsules because it is a specific technique used to encapsulate materials by inducing phase separation in a polymer solution. This method involves the formation of a coacervate phase, which is a liquid droplet rich in the encapsulated material, followed by solidification to form microcapsules. In contrast, the other options - Physical Method, Chemical Methods, and Physicochemical Methods - are broader categories that encompass various techniques used in microcapsule manufacturing.

Submit
5. Which of the following is not involved in the physical method of microencapsulation?

Explanation

Ionotropic gelation is a chemical method of microencapsulation, not a physical method. In ionotropic gelation, the encapsulating material is crosslinked by the addition of a crosslinking agent, which is a chemical process. On the other hand, spray-drying, vibrational nozzle, and centrifugal extrusion are all physical methods of microencapsulation, where the encapsulating material is physically transformed into microspheres or particles using techniques such as drying, vibration, or centrifugal force.

Submit
6. Which of the following is not a component of a microcapsule?

Explanation

A microcapsule is a tiny spherical particle that consists of a core material surrounded by a membrane. The core contains the active ingredient or payload, while the membrane acts as a protective barrier. The external phase refers to the surrounding medium in which the microcapsule is dispersed, such as a liquid or solid matrix. Therefore, the external phase is not a component of the microcapsule itself, but rather the environment in which it exists.

Submit
7. Which of these is not a way by which surrounding walls of microcapsules are broken?

Explanation

not-available-via-ai

Submit
8. Which of the following is not an application of microencapsulation?

Explanation

not-available-via-ai

9. When did Barrett K. Green receive the patent for the process of microencapsulation?

Explanation

Barrett K. Green received the patent for the process of microencapsulation on July 5, 1955.

Submit
10. Which of the following is used as a coating material in microencapsulation?

Explanation

Rhodoviol is used as a coating material in microencapsulation.
