Determination of Seven Organic Impurities in FD&C Yellow No. 6 by Ultra-High-Performance Liquid Chromatography.

Background: The U.S. Food and Drug Administration (FDA) batch certifies FD&C Yellow No.

High resolution mass spectral data from the analysis of copper chlorophylls and copper chlorophyll degradation products in bright green table olives.

This publication reports high resolution mass spectral data for copper chlorophyll and copper chlorophyll degradation products extracted from bright green table olives. These data support analyte identifications made in "Quantitation of copper chlorophylls in green table olives by ultra-high-performance liquid chromatography with inductively coupled plasma isotope dilution mass spectrometry" in the A (Petigara Harp , 2020 [1]). Table olive pigments, divided into lipophilic and hydrophilic fractions by liquid-liquid repartition, were separated by ultra-high-performance liquid chromatography and detected by visible wavelength absorbance and high resolution mass spectrometry, using an Orbitrap HF with positive electrospray ionization.

Quantitation of copper chlorophylls in green table olives by ultra-high-performance liquid chromatography with inductively coupled plasma isotope dilution mass spectrometry.

Table olives, a widely consumed delicacy, are often selected by consumers based on the shade of their green color. The appealing coloration of fresh olives fades to brown or pale yellow during the industrial processing necessary for commercialization and storage, as a result of the degradation of chlorophyll a and b to their corresponding pheophytins and other chlorophyll degradation products (CDP). The re-greening of table olives may be achieved by complexation of CDP with Cu, to form stable bright green copper CDP (Cu-CDP) complexes.

Determination of Seven Manufacturing Impurities in FD&C Red No. 40 by Ultra-High-Performance Liquid Chromatography.

Background: The U.S. Food and Drug Administration batch-certifies color additives to ensure that each lot meets published specifications for coloring food, drugs, and cosmetics.

Ultra-Performance Liquid Chromatographic Determination of Manufacturing Intermediates and Subsidiary Colors in D&C Red No. 6, D&C Red No. 7, and Their Lakes.

An ultra-performance LC (UPLC) method was developed to determine the manufacturing intermediates and subsidiary colors in the monosulfo monoazo color additives D&C Red No. 6 and D&C Red No. 7 and their lakes.

Qualitative identification of permitted and non-permitted color additives in cosmetics.

Color additives are dyes, pigments, or other substances that can impart color when added or applied to foods, drugs, cosmetics, medical devices, or the human body. These substances must be pre-approved by the U.S.

Determination of seven certified color additives in food products using liquid chromatography.

This study describes a new method for determining FD&C Blue No. 1, FD&C Blue No. 2, FD&C Green No.

Qualitative identification of permitted and non-permitted colour additives in food products.

Colour additives are dyes, pigments or other substances that can impart colour when added or applied to food, drugs, cosmetics, medical devices, or the human body. The substances must be pre-approved by the US Food and Drug Administration (USFDA) and listed in Title 21 of the US Code of Federal Regulations before they may be used in products marketed in the United States. Some also are required to be batch certified by the USFDA prior to their use.

Ultra-performance liquid chromatographic determination of manufacturing intermediates and subsidiary colors in D&C Red No. 34 and its lakes.

An ultra-performance liquid chromatography (UPLC) method was developed to determine the manufacturing intermediates and subsidiary colors in the monosulfo monoazo color additive D&C Red No. 34 and its lakes. This method is currently used for batch certification of the color additives by the U.

Reversed-phase liquid chromatographic determination of two manufacturing intermediates in D&C Red No. 34 and its lakes.

A reversed-phase LC method was developed to determine two manufacturing intermediates in the monosulfo monoazo color additive D&C Red No. 34 and its lakes. The analytes are 2-amino-1-naphthalenesulfonic acid (Tobias acid) and 3-hydroxy-2-naphthalenecarboxylic acid (3-hydroxy-2-naphthoic acid).

Reversed-phase LC determination of two manufacturing intermediates, the unsulfonated subsidiary color, and 4-methyl-Sudan I in D&C Red No. 6, D&C Red No. 7, and their lakes.

A reversed-phase liquid chromatographic (LC) method was developed to determine 4 impurities in the monosulfo monoazo color additives D&C Red No. 6, D&C Red No. 7, and their lakes.
