which separating technique will be used in extracting coconut milk from grated coconut?
The correct answer and explanation is:
Correct Answer: Filtration (or Expression followed by Filtration)
Explanation (300 words):
The primary separating technique used in extracting coconut milk from grated coconut is filtration, often following expression (manual or mechanical pressing).
When coconut milk is extracted, the process generally involves grating the white flesh of a mature coconut and then adding a small amount of warm water. This mixture is kneaded or pressed to release the coconut milk, which is a white, opaque liquid composed of water, coconut oil, and finely dispersed proteins.
After pressing or squeezing the grated coconut, the mixture contains both liquid (coconut milk) and solid residues (grated coconut pulp or fiber). To separate the milk from these solid particles, filtration is applied. This can be done using a muslin cloth, cheesecloth, or a fine mesh strainer. The solid particles are retained on the filter, while the coconut milk passes through as the filtrate.
Sometimes, the process is referred to more broadly as expression followed by filtration, because the first step is to physically extract the liquid through squeezing or pressing, and then the actual separation of liquid from residual solids is completed by filtering.
Filtration is ideal for this purpose because it effectively separates components based on particle size. The fine mesh or cloth traps the larger solid particles of the grated coconut, allowing only the liquid portion to pass through, resulting in smooth, clean coconut milk.
This technique is simple, efficient, and commonly used in household kitchens and small-scale processing. In commercial setups, mechanical presses and industrial filters might be used for greater efficiency, but the underlying principle remains the same: separating liquid coconut milk from solid coconut pulp through filtration.
Therefore, filtration is the most accurate term to describe the separating technique used in extracting coconut milk from grated coconut.
