The trick to using stain to reduce or eliminate yellowing is to use a pigmented stain, not clear. The pigment should be the same color as the natural wood color. For instance, birch would be stained with a "birch" stain. This puts a pigment layer on top of the wood to block out UV light and inhibit yellowing.

What caused my sealer to turn yellow/brown? Some sealers use resins that are not light stable. Long term exposure to UV sunlight can cause them to become yellow or brown in appearance.
This may happen when joints are taped before painting of ceilings or walls. Ingredients from the layer of glue can migrate into the sealant surface and lead to yellowing after the tape is removed. Acid and alkaline vapours from, for example detergents, may result in the yellowing of the sealant.
The Short Answer: All polyurethane will yellow over time. While modern technology has extended the amount of time it takes to yellow and reduced the extent it can yellow by, ALL polyurethane (including polyacrylics) will yellow.
Polyurethane materials are sensitive to UV radiation, temperature and humidity, and photothermal oxidation, hydrolysis and degradation caused by heat and light accelerate the yellowing of polyurethane products.
Will Polycrylic turn yellow?
Polycrylic, on the other hand, leaves a clear, non-yellowing surface, so it won't change the appearance of lighter woods such as maple or birch, or anything painted white.
Shellac – Shellac is a varnish made from the resin of the lac bug. It is a softer finish that is often recommended for lighter-colored woods. It is also better for areas with high moisture and frequent wear, as it dries much faster than polyurethane.

Why does wood go yellow?
Many sprayers use pre-catalysed lacquer to finish wood surfaces, due to its cost-effectiveness and durability. Whilst these lacquers are often excellent at protecting surfaces, any finish with nitrocellulose in it will oxidize the substrate when exposed to UV, thus resulting in yellowing.
Wax, oil and varnish are three materials that will protect your furniture and that you can easily apply at home yourself. The three options will maintain the most "natural" aspect of the furniture, preserving the grain of the wood without adding big touches of colour, as paints, lacquers, etc. would do.
- Sometimes takes on a milky appearance when applied to dark woods.
- Requires a longer curing time, even though it dries fast.
- Fast drying time means brush strokes may be visible.
- Is not as resistant to high heat.
In terms of durability, polyurethane coatings are more resistant to water, chemicals, UV light, and other elements that lead to peeling. They can also be recoated within a day or two after being applied. In contrast, urethane coatings take longer to cure before they can be recoated—usually around 24 hours or longer.
Do water based polyurethanes turn yellow over time? Water borne poly yellows less than oil based poly (which turns very yellow). The the amount of yellowing over time will vary based on the strength and grade of the polyurethane. Both wood and poly will react with UV rays.
Shellac: The natural choice. This traditional finish comes from natural resins secreted by the lac bug. These secretions are collected and processed into flakes that dissolve in ethyl or denatured alcohol. You can also buy shellac premixed, it's slightly cheaper than polyurethane.
