Sweeter and bigger! Development of a bag to cover grapes with state-of-the-art materials Shinshu University October 6 16:56
Shinshu University has developed a bag for fruit cultivation using nanofibers, a state-of-the-art material.
It has been confirmed that the fruit grows sweetly by growing using this bag, and it is attracting attention as it can increase the value of grapes, which are special to the prefecture.
The bag covered with grapes was developed by a research team of Professor Kim Ix of Shinshu University’s Faculty of Textiles.
In the cultivation of grapes, bags are placed to protect the fruit from pests, but the research team developed the bag using nanofiber, an extremely thin fiber used in automotive parts and regenerative medicine.
According to the research team, the developed bag has better breathability than the paper bag used in general, so the influence of the temperature difference increases and the sweetness increases, and it becomes less likely to become a moldy disease.
In fact, when grown over Shine Muscat and Nagano Purple, it was confirmed that the sugar content increased by about 7% on average, and the mass per grain increased by nearly 10%.
The research team is aiming to further enhance the value of grapes, which are special to the prefecture, and aim to mass-produce them and expand them nationwide for next year.
Professor Kim said, “Not only grapes, but also other fruits such as peaches and pears should make a difference, so I would like to proceed with my research.”
