ペンシルバニア州立大学の研究者による新しい研究によれば、水草であるカロライナアゾラは、2日でバイオマスを倍増させ、空気中から窒素を捕獲し、価値ある緑の肥料となる可能性があります。この植物は家禽や家畜に餌として与えることもでき、災害や緊急時に人間の救命食として役立つかもしれません。カロライナアゾラは栄養価が高く、人間の消化に適しています。この植物は災害時や普段の農業で重要な資源となり得るが、さらなる研究と開発が必要です。

一般的な植物が食料不安の軽減に役立つ可能性を研究者らが発見(Common plant could help reduce food insecurity, researchers find)

Abstract

Azolla caroliniana Willd. is an understudied wild edible plant native to the Eastern United States. Other species of Azolla have been used across the world for several thousand years as a livestock feed and as “green manure.” The use of Azolla for human consumption is thought to be limited by its high total polyphenolic content (TPC). However, the TPC and nutritional content of A. caroliniana has not been thoroughly studied. We measured TPC and other nutrients before and after cooking methods designed to lower TPC. We found that TPC was 4.26 g gallic acid equivalent (GAE) kg−1 DW in raw A. caroliniana. All cooking methods significantly lowered TPC. Protein content was 19% DW, and the apparent protein digestibility was 78.45%. Our yield was 173 g FW m−2 day−1 and 5.53 g DW m−2 day−1. Azolla caroliniana is a high-yielding plant with great potential for cultivation and domestication.
