While the famous kaoliang (高粱酒) produced in Kinmen has already brought enormous income to the offshore island, researchers say they have now developed new technologies to make the wasted sorghum grains into value-added products.
National Quemoy University’s (NQU) Department of Food Science assistant professor Lin Chi-fan (林志芳) said more than 100 tonnes of waste sorghum grains — the by-product of the fermentation process — are being produced at government-owned Kinmen Kaoliang Liquor Co every day and are mainly used as fertilizers, which he said was not the best way of recycling them.
Kinmen Kaoliang Liquor’s statistics showed that about 25 million tonnes of kaoliang was produced last year, bringing in about NT$13.6 billion in revenue. It is estimated that kaoliang production may reach 27 million tonnes this year.
After experimenting with different ways to recycle the waste sorghum grains, Lin discovered that by extracting them into a powder and adding them to various food products, it enhanced the flavor and the nutritional value of the food.
“They can be added into bread and cookies, as people now like to eat whole-grain products for health reasons, and because they have a special flavor and high acidity they can also be put into preserved sour cabbages,” Lin said, adding that high acidity of lower than a 4.6 pH level can serve as a preservative agent and that they can used to make soy sauce.
Other than being used as a food ingredient, NQU’s Department of Food Science assistant professor Lai Ying-Jang (賴盈璋) has developed a method to make dried waste sorghum grains into activated carbon, which can be used as a filtration or moisture-proof preservative in several ways — such as being added to spice containers to keep them dry and to absorb odors, for filtering drinking water or in medical products.
“Results showed that about 25kg of activated carbon can be produced from every 100kg of dried waste sorghum grains,” he said, adding that activated carbon is smaller, easier to store and that it cost about 10 times the price of sorghum grains.
The results of a collaborative research project by NQU and National Chiayi University, Lai said the team plans to apply for a patent for the technology that produces activated carbon from dried waste sorghum grains.
CLEAR BEFORE LEAVING: Two baby boys and a woman in her 30s tested negative before departing for Japan, but tests taken after their arrival came back postive Three Taiwanese tested positive for COVID-19 when they arrived in Japan earlier this month, the Central Epidemic Command Center (CECC) said yesterday as it reported a new imported case. Minister of Health and Welfare Chen Shih-chung (陳時中), head of the center, said that one of the three cases in Japan is a Taiwanese baby under the age of one, whose parents work in Japan. The infant came to Taiwan with his parents in January, and the parents paid for the family’s COVID-19 tests on Oct. 10 ahead of their planned return to Japan on Monday last week, he said. The boy and his
‘BACKED BY ENEMY’: CTi News is one of the few channels promoting unification, the New Party chairman said, while pro-Taiwan groups called it a propaganda outlet Pan-blue camp supporters yesterday lodged a protest at the National Communications Commission (NCC) against what they say is a possible move by the government to shut down CTi News, adding that politics should not interfere with freedom of the press. Protesters included representatives from the New Party, the Blue Sky Action Alliance, the 333 Political Party Alliance and other pan-blue groups. “We stand here today because CTi News is one of the few media outlets in Taiwan that is still willing to give groups supporting unification with China a voice. If the news channel is gone, there would only be
NEW YEAR’S EVE: Examples from South Korea and Japan show that 15 local COVID-19 infections could emerge in a short period if measures are not taken The Taipei City Government would cancel its New Year’s Eve Party and all large events if 15 or more confirmed cases of COVID-19 are reported in the city within a week, Taipei Mayor Ko Wen-je (柯文哲) said yesterday. Addressing the Taipei Cross Border E-Commerce Annual Convention, Ko said the COVID-19 pandemic has brought many uncertainties to society, and that e-commerce is on a path of no return and would continue to grow. Many countries have not effectively controlled their COVID-19 outbreaks, and although Taiwan implements strict border controls and there have been few inbound passengers, the pandemic is unlikely to end soon,
The Democratic Progressive Party (DPP) yesterday accused CTi News of trying to mislead the public by publishing a half-page advert claiming that the party interfered in the National Communications Commission’s (NCC) review of its application for a license renewal. CTi News is distorting the commission’s review process by painting it as a political conflict and turning it into a smear campaign against the DPP, party spokeswoman Yen Juo-fang (顏若芳) said. “The NCC is an independent body, which carries out reviews and makes decisions based on its members’ professional expertise, as well as regulations and legal requirements governing media operations,” Yen said. “We condemn
