Utilization of Bushukan Citrus Peel via Lactic Acid Fermentation

چکیده

ブシュカンは,高知県の四万十市で多く栽培されている香酸柑橘の1つである.ブシュカンは特徴的な芳香をもち,四万十市域では果汁とともに果皮も利用され,香りが楽しまれている.一方で,商業的に果汁を搾ったあとの果皮は廃棄物となるため,その利用を試みた.果皮に新たな付加価値を付与することを目的として,乳酸桿菌を用いた乳酸発酵を行った.ブシュカンの花から新たに分離したLatilactobacillus sakei,石鎚黒茶由来のLactoplantibacillus plantalumまたはLevilactobacillus brevisと,ペースト状にし,スクロースを添加したブシュカン果皮とを混合し,37℃で4日間保持した.4日後のブシュカンペーストでは,酸度の上昇とpHの低下がみられた.また,乳酸量が増加していたことから,乳酸発酵が行われたと考えられた.L. sakeiおよびL. plantarumによる発酵物について,d-アミノ酸の産生が認められた.これらのことから,ブシュカン果皮の乳酸発酵は,果皮に機能性を付与し,新たな利用可能性を与えると考えられる.

Local domestication of lactic acid bacteria via cassava beer fermentation

Cassava beer, or chicha, is typically consumed daily by the indigenous Shuar people of the Ecuadorian Amazon. This traditional beverage made from cassava tuber (Manihot esculenta) is thought to improve nutritional quality and flavor while extending shelf life in a tropical climate. Bacteria responsible for chicha fermentation could be a source of microbes for the human microbiome, but little is...

Phytic acid degrading lactic acid bacteria in tef-injera fermentation.

Ethiopian injera, a soft pancake, baked from fermented batter, is preferentially prepared from tef (Eragrostis tef) flour. The phytic acid (PA) content of tef is high and is only partly degraded during the fermentation step. PA chelates with iron and zinc in the human digestive tract and strongly inhibits their absorption. With the aim to formulate a starter culture that would substantially deg...

Extractive Fermentation of Lactic Acid in Lactic Acid Bacteria Cultivation: A Review

Lactic acid bacteria are industrially important microorganisms recognized for their fermentative ability mostly in their probiotic benefits as well as lactic acid production for various applications. Nevertheless, lactic acid fermentation often suffers end-product inhibition which decreases the cell growth rate. The inhibition of lactic acid is due to the solubility of the undissociated lactic ...
