How to improve texture and shelf life of baked goods by increasing moisture retention and structure

two photographs of vanilla cake slices, one without methocel on the left and one with 0.25% added methocel F4M on the right, appear in the upper-half of the page beneath the advertisement title on a white background. the slice with methocel is distinctively taller and more uniform in crumb-texture.

How to improve texture and shell life of baked goods by increasing moisture retention and structure
Without METHOCEL

With METHOCEL F4M @ 0.25%
Improved volume and uniformity of crumb structure with METHOCEL gums are due to enhanced moisture retention, film-forming properties, and thermal gelation which aids in batter stability and the formation of larger, stronger gas cells.
The answer is to add one of the versatile family of METHOCEL* Premium food gums-just 0.2-0.5% in cakes, doughnuts, and pastries. The result is spongier, lighter, more symmetrical textures that stay that way longer on the shelf. Because when it comes to versatility, METHOCEL gums have no match. The keys are the ability of METHOCEL gums to thermally gel and to retain moisture. Thermal gelation produces batter stability which leads to good “over-spring”; the building and stabilizing of volume during the early stages of baking. Enhanced stability means voids in the product are more uniform in size which leads to more uniform crumb structure. Then the gel protects this structure from falling by strengthening the gas cells. The moisture holding capacity of METHOCEL gums further enhances product texture… initially over time. Increased moisture retention also helps improve product yield. Since water stays put there’s less need to compensate with more of the other ingredients in the mix. Increases in yield of two to three percent are typical. In short, due to their versatility, METHOCEL Premium food gums are very useful in a wide variety of baked goods. And remember, very small addition rates enable you to gain these benefits at a cost that can be quickly offset with increased baked product yield. Plus, unlike other gums, you work with a product that’s consistently predictable, that doesn’t affect product flavor, that’s readily available and easy to incorporate into your systems.

Baked Volume Comparison Chocolate Cake Mix
Cake Height, mm: 0, 10, 20, 30, 40, 50
METHOCEL*: 41.2mm
Control: 37.25mm
In a comparison test with a microwaveable chocolate cake mix, the addition of METHOCEL Premium food gum increased cake height an average of 10.6% and allowed additional moisture retention, providing a moister texture.

[additional notes]
(Marjan Stuckart)
the comparison between the two vanilla cake slices with and without 0.25% methocel F4M is eye-catching while the graphs comparing volume and moisture retention support the visual difference through data. why was a larger volume and more uniform crumb structure considered an improvement at the time and would it still be considered one now? what are some of the potential detriments to using methocel in a baked good?
