Should you remove seeds from tomatoes when making sauce?
If you’re making a fresh tomato sauce or stewed tomatoes, the tomatoes should be peeled, cored, and seeded. The result will be a smoother sauce without any seeds, core, or peel in it.

Which method of tomato seed extraction is generally used in temperate areas?
Alkali method
This method is relatively safe and can be used for small quantities of seed in cooler temperate areas where the fermentation method is not used. The pulp containing the extracted tomato seed is mixed with an equal volume of a ten per cent solution of sodium carbonate (washing soda).
How do you extract tomato seed oil?
Tomato seed oil has previously been effectively extracted using supercritical CO2 (SC-CO2) [6, 10]. In addition, SC-CO2 has been used to extract minor constituents from tomatoes, including phytosterols [11], tocopherols [11, 12], β-carotene [6, 11–13] and lycopene [6, 11–16].

The most common method of separating a liquid from an insoluble solid is the filtration. Take, for example, the mixture of sand and water. Filtration is used here to remove solid particles from the liquid.
What method of separating mixture will you use if you want?
Mixtures can be physically separated by using methods that use differences in physical properties to separate the components of the mixture, such as evaporation, distillation, filtration and chromatography.
How will you separate the components of a mixture containing pulp and juice?
Since juice is liquid in nature and the fruits pulp is solid (fibrous). The liquid will pass through filter paper and pulp will remain in it..
