Abstract： In this study， dried grapefruit peel was used as raw material， Lactobacillus was used as fermentation strain， and naringin， the main bitter substance in grapefruit peel， was used as the standard material to make the standard curve. Through single factor test， it was found that the best conditions to remove the bitter taste of grapefruit peel were the addition of Lactobacillus 5%， the addition of grapefruit pulp 40%， the culture temperature 35 ℃ and the culture time 48 h， the bitterness reduction rate of naringin was the largest.

Keywords： Lactobacillus; naringin; grapefruit peel; fermentation; go bitter

柚子果肉口感好，柚子皮的活性成分多，但柚子皮味辛苦甘，其苦味在使用柚子皮制作產(chǎn)品時(shí)影響較大，因此在開發(fā)利用柚子皮制作果脯、果酒等產(chǎn)品時(shí)，需去除柚子皮的苦味物質(zhì)[1-2]。（剩余3437字）
