Degradation of limonin by entrappedRhodococcus fascians cells
Biotechnology Letters, 1989Limonin degradingRhodococcusfascians was immobilized by entrapment in alginate, k-carrageenan, agarose and polyacrylamide gels. Except this latter, gels were used both with and without polyethyleneimine treatment followed by glutaraldehyde crosslinking.

An Improved Enzyme Immunoassay for Limonin
Journal of Food Science, 1988ABSTRACT Performance of the previously reported enzyme immunoassay for determination of limonin in citrus juice was improved by stabilization of anti‐limonin‐antibody‐coated microtitration wells with 1% solution of ovalbumin and polyvinyl alcohol.

A limonin‐degrading enzyme in citrus albedo
Journal of the Science of Food and Agriculture, 1971AbstractExperiments are described which demonstrate the presence in the albedo of Navel and Valencia oranges of a system with the properties of an enzyme capable of degrading limonin, the bitter principle of orange juice.

Radioimmunoassay for the determination of limonin in Citrus
Phytochemistry, 1980Abstract An 125 I-radioimmunoassay technique has been developed for the triterpenoid bitter principle, limonin. Synthesis of the iodinated tracer and the limonin—bovine serum albumin conjugate are described. The antibody has a high affinity ( K a 1.1 x 10 9 l/mol) and specificity for limonin and the detection limit of the assay is 0.07 ng or 0.7 ...

Removal of limonin from bitter orange juice
Journal of the Science of Food and Agriculture, 1968AbstractPolyamides are shown to be effective adsorbents for removal of the bitter principle, limonin, from pasteurised Washington Navel orange juice. The extent of limonin removal varies with different juices, but sufficient can be removed by one or two treatments to bring the concentration below the organoleptically detectable level.

Stability of limonin glucoside in beverage matrices
Journal of the Science of Food and Agriculture, 2008AbstractBACKGROUND: We completed a study over a 200‐day period examining the stability of limonin glucoside formulated into three beverage matrices.RESULTS: Beverages containing limonin glucoside were found to contain limonin (0.13–20.10 mg L−1) during their initial testing; however, these concentrations were directly attributable to the presence of ...

Limonin is well-known to induce the so-called “delayed” bitterness which is developing during standing and/or processing of orange juice. The objective of this study was to investigate the hydrolytic liberation of limonin from its precursor limonin-17-β-d-glucopyranoside in aqueous model solutions and orange juice samples. Quantitative model studies on

Limonin Bitterness in Citrus Juices
1999Bitterness due to limonin in a variety of citrus juices, generally referred to as delayed bitterness, is a major problem of the citrus industry worldwide and has a significant negative economic impact. Significant progress has been made during the past 30 years in understanding the flavor chemistry and biochemistry of citrus limonoids.

Food Chemistry
Limonin is an intensely bitter and highly oxidized tetracyclic triterpenoid secondary metabolite, which is abundant in the Rutaceae and Meliaceae, especially in Citrus. In order to detect limonin content in complex substrates such as citrus and traditional Chinese medicine, monoclonal antibodies specifically recognizing limonin were prepared and an ...
