Ever thrown out a jar of kimchi because of those pesky white mold bubbles? Fear not – it’s not mold, it’s yeast! Researchers say just skim it off, rinse the veggie, heat it and it’s totally safe to eat. The World Institute of Kimchi (WiKim) released a study on the hygienic safety of the yeast strains that form on kimchi, a report which was published in the Journal of Microbiology. WiKim General Director Dr. Jaeho Ha said the study is significant because “it is a step forward toward the alleviation of the anxiety for hygienic safety of kimchi.”

America could be facing a pickle shortage. Since the mid-2000s, a mildew has been destroying cucumber crops. Fewer farmers are growing cucumbers now because of the high amount of failed harvests. USDA records show pickling cucumber acreage has declined 25 percent between 2004 and 2015. Lina Quesada-Ocampo, vegetable pathologist at North Carolina State University told NPR: “This is the number one threat to the pickle industry.” Thankfully, vegetable breeder Michael Mazourek, a professor at Cornell University, is developing a cucumber variety resistant to mildew.

Two scientists have a patent pending on a brewery invention that detects the wild yeast contaminant Saccharomyces cerevisiae var. diastaticus. The wild yeast causes secondary fermentation in beer production, fermenting unfermentable sugars and overcarbonating brews. A contamination costs brewers millions in recalled product, lost sales and decreased market share. The patent is by a University of Sciences director and his 20-year-old undergrad researcher. The microbiological medium would be marketed for professional and home brewers.

It’s National Pickle Day — Forbes explains why pickles are not a fading trend, but a growing food culture with staying power. The pickle market is growing, reaching a value of $12.74 billion by 2020 (half of that – $6.70 billion – is just in the U.S.). Pickles curb dehydration, are packed with antioxidants like vitamin C and E and the fermented vinegar in the juice is good for your gut. Today, pickle concoctions can be found on most aisles of a grocery store, from sports drinks to popcorn to popsicles.

Research is critical to the future of cacao crops, which are challenged by climate change and disease. Fruity cocoa flavors are related to how the beans are fermented, while floral cocoa flavors are related to the genetics of the crop. Researchers at the Cocoa Research Centre are currently developing cacao varieties that are resistant to drought and particular pests.

Fermented dairy products reduce the risk of heart disease, according to a new study. By analyzing food journals a group of men kept over 11 years, scientists concluded fermented dairy products have great health benefits. Part of the reason this is important is because dairy products with a high-fat content have been villainized by health experts, causing the public to cut back full-fat milk products. However, the new study is now prompting researchers “to question whether dairy products should be evaluated solely on their fat content, but rather their nutritional content.”

Food scientists from the University of Massachusetts Amherst found vegetables are the main source of fermentation-related microbes. Many in the fermentation field commonly think food handlers, food prep surfaces, production environment or other environmental sources effect the bacteria in fermented vegetables. Testing was done as Mass.-based Real Pickles, and the company founder said he was fascinated to learn how fresh, organic vegetables play a key part in a diverse microbial environment for fermentation.
The U.S. Association of Cider Makers is creating a universal dryness scale, a number that can be put on labels to designate whether the cider is dry, semi-dry, semisweet or sweet. As ciders experience a revival in the U.S., the No. 1 issue is customers assuming all ciders are too sweet. Many feel this was the downfall of the popular Riesling wine movement of the late 2000s/early 2010s. The scale could be applied to all fermented beverages, where dryness factors could be tested in a lab.

Spontaneous fermentation is seeing a big surge among breweries. It’s a method beer, cider, wine and liquor makers should consider because spontaneous fermentation is a sign that the brewer is confident in their technique, willing to trust the uncontrolled aspects of the fermentation process and having fun, says Bon Appetit magazine. Also known as hands-off, natural or traditional fermentation, it’s the oldest form of fermentation, used before fermentation could be controlled and regulated.
