Abstract Huanglongbing (HLB) is a plant disease responsible for citrus tree decline, increased fruit drop, and deteriorated fruit quality. Citrus pectin is a billion-dollar industry which may be impacted by the HLB epidemic. We compared the physio-chemical properties of pectin in peel from HLB affected grapefruit collected from open-air trees against healthy grapefruit grown under protective screens (CUPS) at two developmental stages to ascertain HLB impacts on pectin. qPCR detected the causal agent of HLB, which determined if the tested fruit was healthy or non-healthy, and peel color and °Brix defined the fruit’s maturity. Depending on the maturity of the HLB affected grapefruit there was between a 16%-25% decrease in pectin yield. HLB affected pectin showed significantly (p
