HPMC in all-barley and all-oat breads

What it found

Adding HPMC to all-barley and all-oat breads made the loaves up to 2 times larger and softer right after baking and for up to 3 days of storage.

In taste panels, barley bread with HPMC scored highest for overall acceptability.

What they found

Studies in people

Taste panel scores

Barley bread with HPMC was rated the highest in overall acceptability by sensory panelists, compared to oat and wheat breads with or without HPMC.

Other findings

Loaf volume

HPMC increased the loaf volume of the breads by up to 2 times.

Softness after baking

Breads with HPMC were less hard immediately after baking.

Softness during storage

Breads with HPMC were also less hard after up to 3 days of storage.

What the authors conclude

“Barley bread with HPMC was rated the highest in overall acceptability by sensory panelists compared to oat and wheat breads with or without HPMC.”

Also in their conclusions

  • They report that HPMC improved the physical and sensory properties of all-oat and all-barley breads.
  • They note that barley bread with HPMC was rated the highest in overall acceptability by sensory panelists.

How it was done

Consumers tend to avoid whole wheat breads, so the authors looked at oat and barley breads with HPMC instead. Oat and barley also contain beta-glucan, a glucose polymer similar to HPMC that also lowers cholesterol.

They baked all-oat and all-barley breads with and without added HPMC, plus wheat breads for comparison. They measured texture and other physical properties with instruments and chemical methods, and had sensory panels rate the breads.

What it can’t tell you

  • We summarised it from the abstract only.
  • The taste panel ratings come from the people who took part and may not match how all shoppers would rate these breads.
  • The study did not measure cholesterol or other health effects in people.
