Benefits Of Fermented Cucumbers

Yearning for a pickle? Go on and take a bite. Fermented vegetables are a healthy choice for a treat.

Cucumber pickles are the most typically consumed fermented veggie in the United States, with Americans consuming more than 9 pounds of all types of pickles per person each year. Pickles are fat complimentary, cholesterol totally free, low in calories, and a great source of vitamin K.

But there's not much clinical proof that informs us whether fermented cucumbers are more healthy than raw ones.

Research study on possible health advantages of fermented foods has primarily concentrated on consumption of live bacteria and the subsequent probiotic effects, says Suzanne Johanningsmeier, research food technologist at the Agricultural Research Service (ARS) Food Science Research Unit in Raleigh, North Carolina. More just recently, focus has been placed on health-promoting substances called bioactive peptides, which are short chains of amino acids, discovered in fermented foods.

Peptides that have healing residential or commercial properties are well recorded in many fermented foods, including dairy products, sourdough, and treated meats-- but not in fermented veggies, Johanningsmeier states. One factor could be that cucumber pickles are tough to evaluate with existing peptide approaches because of their salt content. So Johanningsmeier and her graduate research assistant, Jennifer Fideler, partnered with North Carolina State University scientists, who developed an unique mass spectrometry technique that enabled the pickle components to be analyzed in spite of the salt content.

Utilizing this innovation, scientists determined, for the first time in fermented cucumbers, 4 peptides understood to have anti-hypertensive properties. "This discovery supports the historical view of the healthfulness of these products," Johanningsmeier states. "Although these peptides were present at low concentrations compared to other food parts, they might boost the healthfulness of the products because of their high effectiveness."

The discovery of these peptides in fermented cucumbers may be good news for consumers looking for healthy foods. There's also the possibility of recuperating these peptides from surplus fermentation brines for usage as functional active ingredients. However all this remains to be seen.

"This initial research study took a look at whether there was a distinct contribution of the fermentation procedure to the development of health-promoting substances," Johanningsmeier says. "We're simply beginning with this line of research study. In the end, we might discover just as lots of healthy constituents in other types of pickled vegetables. Further research study is required to determine if these compositional modifications during fermentation remain in adequate quantities for a health advantage."
