ORANGE PEELING

Vanillin is known to cause allergic reactions in people previously sensiti2ed to balsam of Pern, ben2oic acid, orange peel, cinnamon, and clove, but vanillin itself is not an allergic sensiti2er. 

OP = orange-peel effect si OP = slight orange-peel effect. 

Iron. This is a specialty drier that is considered active at temperatures of about 130°C. For this reason iron 2-ethyIhexanoate [19583-54-1] is used in bake coatings that require maximum hardness. The principal drawback of using iron driers is that iron contributes a characteristic brownish red color to the coating and should only be used in dark pigmented systems. It has been reported that iron aids the dispersion of carbon black pigment and reduces the tendency for orange peel film defects (6).

The use of small amounts of the material in paints and surface coatings is claimed to help in eliminating faults such as silking in dipping applications and orange peel in stoved finishes. 

Crude turpentine is distilled to obtain refined products used in the fragrance and flavour industry. Only the unsaturated mono- and bicyclic terpenes are of interest for resin production. These are mainly a-pinene, p-pinene and dipentcne (D,L-limonene) (Fig. 17). D-Limonene is obtained by extraction of orange peel in citrus fruits.

The method was then applied to extracts of orange peel but neither benomyl or thiophanate methyl were recovered as the parent compounds due to their well-known conversion to carbendazim during the extraction process - this is an effect that is not encountered when analysing standards.

However, since pectins can be methylesterified and/or acetylesterified, sections were treated on grid with an orange peel methylesterase to remove the methyl groups or with NaOH to remove both methyl and acetyl groups. After the enzymatic treatment, all the primary walls of most of the samples bind the... 

Acetyl esterase (AE) has been purified to homogeneity from orange peels. The purification steps included cation exchange chromatography and gel filtration. The enzyme has affinity for triacetin and sugar beet pectin with K, of 39 mM and of 26 mg/ml, respectively. AE has a MW of 42 kD and is a monomer. The isoelectric point is at pH > 9. 

AE was purified from orange peels. After homogenization, precipitation with 30 - 60% (NH4)2S04 followed by dialysis, the sample was applied to a cation exchange column (CM-Sepharose CL-6B). AE binds strongly to a cation exchange column material at pH 6.8... 

Contrary to AE from orange peels described by Williamson (2) this AE has a higher molecular mass and pi > 9. AE isolated from mung bean, however, has. similar MW and pi in agreement with the present findings (1). These differences could indicate the presence of several AE isoformes in different varieties of orange fruits. 

CTl hyperproduces pectinases on "citrus pectin " as well as on "orange peel" local substrate. 

One of the important criteria taken into account for the choice of an industrial producer strain is its ability to secrete enzymes on cheap and local substrate. Thus, we cultured our mutant as well as the Pol6 mutant on a local substrate milled "orange peel", at the same concentration as citrus pectin in the liquid medium. The results summarized on table 3 show a net difference between both strains the CTl mutant is able to produce high amounts of endo and exopectinases on both substrates whereas Pol6 is unable to hyper-produce both pectinases on "orange peel".
