A team at National Pingtung University of Science and Technology (NPUST) has developed a process that could help address excess regional fruit production and people’s fear of chemical compounds in tapioca jellies, such as those used in bubble tea.
The team used bananas to test the method, as team leader and NPUST food sciences professor Hsieh Pao-chuan (謝寶全) predicted a banana surplus, he said.
“I have always thought about how I could help farmers reduce their losses in times of surplus,” Hsieh said.

“We wanted to make fruit tapioca jellies, as those are popular at home and abroad,” he added.
Taiwanese consume about 1 billion cups of tapioca per year, Hsieh said, adding that the tapioca market has a global value or NT$1.5 trillion (US$49 billion).
However, most tapioca jellies on the market are laced with food additives, and many so-called brown sugar tapioca jellies are really made with caramel, he said.
The texture of tapioca is usually due to food additives, but the team’s fruit jellies use starch derivatives free of phosphorous pentoxide, he said, adding that they offer the same texture and flavor while doing away with the issue of excessive residual phosphate.
The team’s jellies could be frozen for up to two years and Hsieh is in talks with potential factories about selling the technology, he said.
Hsieh is known for his research on and production of soy sauce, of which the university store sells more than NT$10 million per year.
POLAM KOPITIAM CASE: Of the two people still in hospital, one has undergone a liver transplant and is improving, while the other is being evaluated for a liver transplant A fourth person has died from bongkrek acid poisoning linked to the Polam Kopitiam (寶林茶室) restaurant in Taipei’s Far Eastern Sogo Xinyi A13 Department Store, the Ministry of Health and Welfare said yesterday, as two other people remain seriously ill in hospital. The first death was reported on March 24. The man had been 39 years old and had eaten at the restaurant on March 22.

A fourth person has died in a food poisoning outbreak linked to the Xinyi (信義) branch of Malaysian restaurant chain Polam Kopitiam (寶林茶室) in Taipei, Deputy Minister of Health and Welfare Victor Wang (王必勝) said on Monday. It was the second fatality in three days, after another was announced on Saturday. The 40-year-old woman experienced multiple organ failure in the early hours on Monday, and the family decided not to undergo emergency resuscitation, Wang said. She initially showed signs of improvement after seeking medical treatment for nausea, vomiting and diarrhea, but her condition worsened due to an infection, he said. Two others who
MEDICAL: The bills would also upgrade the status of the Ethical Guidelines Governing the Research of Human Embryos and Embryonic Stem Cell Research to law The Executive Yuan yesterday approved two bills to govern regenerative medicine that aim to boost development of the field. Taiwan would reach an important milestone in regenerative medicine development with passage of the regenerative medicine act and the regenerative medicine preparations ordinance, which would allow studies to proceed and treatments to be developed, Deputy Minister of Health and Welfare Victor Wang (王必勝) told reporters at a news conference after a Cabinet meeting. Regenerative treatments have been used for several conditions, including cancer — by regenerating blood cells — and restoring joint function in soft tissue, Wang said. The draft legislation requires regenerative treatments
Taiwanese should be mindful when visiting China, as Beijing in July is likely to tighten the implementation of policies on national security following the introduction of two regulations, a researcher said on Saturday. China on Friday unveiled the regulations governing the law enforcement and judicial activities of national security agencies. They would help crack down on “illegal” and “criminal” activities that Beijing considers to be endangering national security, according to reports by China’s state media. The definition of what constitutes a national security threat in China is vague, Taiwan Thinktank researcher Wu Se-chih (吳瑟致) said. The two procedural regulations are to provide Chinese
