Foods Explores Fermentation

The international journal Foods is deep-diving into fermentation this month with a special issue: New Insights into Food Fermentation. Eleven research papers cover lactic acid bacteria, yeasts, food quality, food safety, unconventional food matrices, byproduct valorization, technological processes, strains selection, microbiological characterization and microbial community in fermented foods.

Fermented products studied include: fish sauce, natto, suanzhayu (Chinese fermented fish), artisanal sausages, cheese and fermented beverages and fruit.

“Food fermentation has been used since ancient times for food preservation. At present, fermented foods are still and even more appreciated by consumers thanks to the high quality and safety standards achieved, and the improvements in terms of nutritional and organoleptic characteristics. Many foods are still produced following traditional practices but novel approaches to food fermentation have also attracted the interest of researchers and industries. Innovative technological and biological processes, as well as novel approaches of investigation, deeply interact to steer traditional products into modern diet and to open up perspectives for the fermentation of unconventional substrates and food byproducts,” writes the issue’s guest editors, professors Valentina Bernini, PhD (University of Parma, Italy) and Juliano De Dea Lindner, PhD (Federal University of Santa Catarina, Brazil).

Singapore’s so-called “Prince of Fermentation” wants his country to develop “its own brand of fermentation culture.” Tan Ding Jie says Singapore’s traditional ferments are often left out of “the gospel of fermentation.”

“Cinchalok, fish sauce, fermented bean curd, fermented bamboo shoots – these are all very interesting ideas. People who are more mature have been quite ready to adapt koji from Japan and red yeast rice from Asia in their Western restaurants – so I think we should also be able to adapt or loan some of their ideas and use them in our cuisine.”

Tan Ding Jie, a researcher for Singapore’s Agency for Science, Technology and Research, is currently pursuing a master’s degree in food science. Jie consults for different Singapore restaurants and bars on how to use ferments in their menus. He created a fish sauce and nata de coco at the Michelin-starred Labyrinth restaurant, and created kombucha-infused cocktails for Gibson, one of Asia’s top bars. He started his own brand, Starter Culture, and teaches fermentation workshops and sells his own kombucha.

In an interview with Channel News Asia, Jie said he thinks there’s “much to be discovered from looking into our Southeast Asian culinary heritage. … I think Singapore is unique because we haven’t been afraid to say, ‘Let’s learn what are the best practices in the world today, and then apply it to our local context.’ If you look at Southeast Asian ferments, it’s also very simple – we took what immigrants brought over and said, ‘All right, that’s the history, let’s make it local.’”

In America, where 40% of the population identifies as nonwhite, why do grocery stores still have an ethnic aisle? The outdated aisle initially began after World War II as a way for soldiers to buy the food they ate while in Italy, Germany or Japan. But the European foods, like pasta sauces and sauerkraut, eventually became integrated with the rest of the store, while foods from BIPOC countries stayed put. 

Heads of ethnic food brands and grocery chains have been pushing for a change, but it’s been a hard sell. Doing away with the aisle is a layered problem — and still not the most popular approach with food professionals.

“Several food purveyors of colors see the aisle as a necessary evil — a way to introduce their products to shoppers who may be unfamiliar with, say, Indian food — though a barrier to bigger success,” reads an article in The New York Times

Some ethnic brands come to store buyers with little capital to get their products on the shelf, so the only spot for them is on the ethnic aisle. They will never break out unless they’re acquired by a larger company. Larger corporations, like Pepsi or Nestlé, can afford to pay stores to put their products on shelves with prime product placement. And large ethnic brands (like Goya beans and Maruchan ramen) are placed on both ethnic aisles and their respective traditional product section because they’re considered broadly recognized.

But many products with international flavors made by nonwhite brands are not placed on the ethnic shelf. The Times shares the story of Toyin Kolawole, who runs the African ingredients brand Iya Foods. Kolawole tried to get her cassava flour into the flour aisle with a Midwestern retailer with no success. But when cassava flour began trending as a substitute for traditional flour, bigger companies launched their own cassava brands — which were put in the flour aisle. 

On the flip side, other food professionals note that consumers turn to the ethic aisle in search of international flavors. Customers like the convenience. There is a fear that unique ingredients (like tamarind or pomegranate molasses) without a clear spot in a grocery store would get lost in a conventional aisle. And, even worse for some brands, integration in an American grocery store means being “divorced from its cultural background.”

Will fermentation be key to the future of the food industry? A third of food produced globally is thrown out, but an article in Forbes explores a promising solution — more companies are using fermentation as a way to decrease food waste. 

A new Danish startup, Resauce, gives companies the resources to turn their food waste into fermented products. Their success stories include a farmer who made fermented onion paste and sauerkraut from excess onions and cabbages, and a vineyard owner who converted grapes into a honey-fermented grape syrup. Each producer then sold their product under their own brand.

Resauce founder Philip Bindesbøll said: “Now we can give companies an innovative product, financial benefits, as well as a positive sustainable story.”

“If there were a country whose cuisine excels in the realm of fermented foods, it’s Japan,” highlights an article in Discover Magazine. In Japan, hakkо̄ (which translates to “fermentation”) forms “the very basis of gastronomy in the island nation,” continues the article.

Tsukemono (pickles), miso (fermented soy bean paste), soy sauce, nattо̄ (fermented soy beans), katsuobushi (dried fermented bonito flakes), nukazuke (vegetables pickled in rice bran), sake and shōchū (liquor distilled from rice, brown sugar, buckwheat or barley) are all staples of traditional Japanese meals. 

Nattо̄ in particular has been proven to lower obesity rates, boost levels of dietary fiber, protein, calcium, iron and potassium and reduce diastolic blood pressure.

Though the article highlights the few, limited studies on the effects of other fermented foods, it also noted how difficult it is to study them. There little money behind the study of traditional foods (outside of yogurt), and participants in any such research would need to be on the same diets and exercise programs in order to produce objective results. A study would also need to take place over multiple years — “the cost would be vast, the ethics questionable.”

Ancient Fermented Beans

The traditional Chinese recipe of fermented black soybeans known as dou si has made the pages of Saveur. Hetty McKinnon, a Chinese Australian cook and author, shares her mother’s penchant for flavoring dishes with these aromatic beans. Dou si is used in salad dressings and dishes like noodles, stews and stir-fries. 

McKinnon writes: “Made from black soybeans that have been inoculated with mold, dou si is then salted and left to dry. Time — six months or so — imparts a robust, multi-dimensional flavor, reminiscent of other aged foods like parmesan cheese and olives. In my kitchen, the ingredient is a weeknight workhorse, and a quick way to add nuance and complexity to a meal with minimal effort and ingredients.”

Fish Sauce Without the Fish

Vegan chefs are creating animal-free fish sauce, using ingredients like seaweed, mushrooms, pineapple, soybeans, black beans and tofu for “the obvious oomph of umami.” A recent piece on Vice.com reported that many of these chefs were reluctant to use anything other than traditional fish-based ingredients. But they’ve found that these new fish sauces are especially popular with younger customers, many of whom are vegan or reducing the amount of meat-based products in their diets.

“Across the animal-free spectrum, home cooks and chefs have gotten creative as they deconstruct and recreate the magic of fermented fish,” continues the article. 

Raj Abat, chef at New York’s plant-based Filipino restaurant Saramsan, was initially skeptical that a vegan fish sauce could work, but he found that fermentation was the transformative element. He said: “My first thought was: It has to look dark and black, and it has to smell really, really bad. Fermentation does that. It makes everything smell really funky, but when you taste it, it’s so delicious.”

How Asian is Fish Sauce?

Food historians, chefs and nutrition experts are divided: could Asian fish sauce have come from Ancient Rome through the Silk Road? There are numerous similarities between the Roman condiment garum and Asian fish sauces, highlights an article in the South China Morning Post. Garum — made by layering salt and fish — was the second most expensive liquid on the market after perfume. Another theory says the local Asian fish sauces like Vietnam’s nuoc mam, Thailand’s nam pla and Japan’s gyosho were not influenced by Roman garum but by China’s ancient soy sauce making. Sauces like nuoc mam use the same fermentation technique as Chinese soy sauce, and they share the same consistency.

“Fermented fish sauces and dishes from different periods and places around the world show that various civilizations have found fermentation to be the best and easiest way to preserve food,” says Giorgio Franchetti, food historian and author of the book “Dining with the Ancient Romans.”
