English : Nutritional Fact Of Tempeh

 

Nutrition Highlights

A serving of soy tempeh is an excellent source of dietary fiber and soy protein. It is also a good source of folic acid, potassium, and iron. Important bio-active components called isoflavones and saponins, found naturally in soybeans, are being studied in relationship to relief of menopause symptoms, such as hot flashes, maintaining healthy bones, and preventing prostate and breast cancers.

Tempeh is a healthy, high-quality protein source that contains all essential amino acids for growth. Soy protein is equal in quality to meat, milk and egg protein, and comes without saturated fat and cholesterol.

In addition to the quality of soy protein, scientists have found that soy protein may help reduce the risk of heart disease by lowering blood cholesterol and increasing the flexibility of blood vessels. The FDA has approved a health claim stating that 25 grams of soy protein in a daily diet low in saturated fat and cholesterol can help reduce total and LDL cholesterol that is moderately high to high.

Loughborough University Research Finds Tempe Linked to better Memory

People who eat high levels of some soy products, including tofu and other so-called ‘superfoods’, may be at an increased risk of memory loss.

Scientists from the Universities of Loughborough and Oxford, funded by the Alzheimer’s Research Trust, worked with Indonesian colleagues to investigate the effects of high soy consumption in 719 elderly Indonesians living in urban and rural regions of Java.

The researchers’ findings, to be published in ‘Dementias and Geriatric Cognitive Disorders’ later this month, include evidence that a high consumption of tofu is associated with worsening memory, particularly among people aged 68 or older.

Lead researcher, Professor Eef Hogervorst of Loughborough University said: “Soy consumption is on the increase in the West and is often promoted as a ‘superfood’. Soy products are rich in micronutrients called phytoestrogens, but it is not entirely clear what their effect on the aging brain is.

“They have similar effects to oestrogen which may offer neuroprotection to the middle-aged and young but not to over 65s for whom it could heighten risk of dementia and lower memory function.”

Intriguingly, the researchers also found that consuming tempe, a fermented soy product made from whole soy bean, is associated with better memory.Professor Hogervorst said the beneficial effect of tempe might be related to its high levels of folate, which is known to reduce dementia risk.

What Is Fermentation

Fermentation in food processing typically refers to the conversion of sugar to alcohol using yeast under anaerobic conditions. A more general definition of fermentation is the chemical conversion of carbohydrates into alcohols or acids. When fermentation stops prior to complete conversion of sugar to alcohol, a stuck fermentation is said to have occurred. The science of fermentation is known as zymology.

Fermentation usually implies that the action of the microorganisms is desirable, and the process is used to produce alcoholic beverages such as wine, beer, and cider. Fermentation is also employed in preservation to create lactic acid in sour foods such as pickled cucumbers, kimchi and yogurt.

Fermentation is one way microorganisms can change a food. Certain bacteria, including lactic acid bacteria, are used to make yogurt, cheese, hot sauce, pickles and dishes such as kimchi.

A common effect of these fermentations is that the food product is less hospitable to other microorganisms, including pathogens and spoilage-causing microorganisms, thus extending the food's shelf-life.

Some cheese varieties also require mold microorganisms to ripen and develop their characteristic flavors.

Tempeh - Introduction

Tempeh/Tempe is made by a natural culturing and controlled fermentation process that binds soybeans into a cake form. It originated from Indonesia, invented by the Javanese, where it is most popular, although it is common in other parts of Southeast Asia as well, introduced by migrated Javanese. It is especially popular on the island of Java, where it is a staple source of protein.

Like tofu, tempeh is made from soybeans, but tempeh is a whole soybean product with different nutritional characteristics and textural qualities. Tempeh's fermentation process and its retention of the whole bean give it a higher content of protein, dietary fiber and vitamins compared to tofu, as well as firmer texture and stronger flavor.

Tofu, however, is thought to be more versatile in dishes. Because of its nutritional value, tempeh is used worldwide in vegetarian cuisine; some consider it to be a meat analogue. Even long before people found and realized the rich nutritional value of tempeh, tempeh was referred to as “Javanese meat.”

History of Tempe

Indonesia - Tempeh processing could be the oldest food technology in the history of Javanese people. Serat Centhini, a book published in the 16th century, indicates that tempeh had been produced and consumed by the time of its publication. Tempeh might have been introduced by the Chinese who are making a similar product, soybean koji, which are dehulled soybeans fermented with Aspergillus molds. The use of Rhizopus as tempeh starter in Indonesia may have been due to its better adaptation to the Indonesian climate. The earliest reference to tempeh by a European appeared in 1875 in a Javanese-Dutch dictionary. The rise of tempeh's popularity in Java and its spread to other parts of Indonesia and other countries of the world began in the 20th century. In the 1970s the banana leaf as container for the production of tempeh was replaced by the use of plastic bags.

Europe - In Europe, tempeh is known through the Dutch who once colonized Indonesia. In 1895 the Dutch microbiologist and chemist Prinsen Geerlings made the first attempt to identify the tempeh mold. The first tempeh companies in Europe were started in the Netherlands by immigrants from Indonesia. The first English written article appeared in 1931 the book "Vegetables of the Dutch East Indies ", written by J.J. Ochse. The earliest popular article about tempeh was a 7 page story published in France 1982 in Le Compas.

USA - In the USA, tempeh has been known only since 1946 with the publication of "Possible Sources of Proteins for Child Feeding in Underdeveloped Countries", in the American Journal of Clinical Nutrition. In the 1960s there was new interest in tempeh with research in tempeh at the Cornell University (New York) and at the USDA Northern Regional Research Center (Illinois). In 1961 Mary Otten was the first to begin making tempeh. Great deal of the credit for introducing tempeh to the American public goes to The Farm, a large spiritual and farming community in Summertown (Tennessee). The first commercial tempeh shop was started in 1975 by Mr. Gale Randall in Undadilla, Nebraska. An article by R. Rodale in "Prevention" in June 1977 brought him and his shop national prominence. In the 1980s when the tempeh industry expanded, the media showed new interest and a lot of articles appeared in scientific journals. During 1983 about 1 million commercial tempeh was produced.

Developing countries - In the 1940s Van Veen tried to introduce tempeh in Zimbabwe. But efforts to introduce tempeh as cheap source of protein in Zimbabwe and other developing countries (Africa and South-America) have mainly failed since the local populations have no experience with mold-fermented foods.

Actual trends - In Europe, the USA and other industrialized countries the interest for tempeh is increasing, by growing interest in health, nutrition and vegetarisme.
