Color Regulatory Affairs Quality Standards for Colors a Safety Color Regulatory Affairs Quality Standards for Colors A safety perspective for the brands Sue Ann McAvoy, MS, CFS Sensient Colors LLC September 23, 2015 Why do we use colorants? Effective Color Usage Drives Consumer Trial and Acceptance • …a lasting color impression is made within 90 seconds and accounts for 60 percent of the acceptance or rejection of an object … • Color has a major impact on flavor perception and flavor acceptance. • Color plays a critical role in product identification. Research has indicated that people “see” flavors (Acree 2013, Lewis and others 2008), i.e, they form an opinion about the flavor of a food or beverage, based on its color. What is Permitted Worldwide? Issues Facing the Global Color Industry .Southampton Study .Sustainability Image can be enhanced by renewable natural colors .Ongoing food safety issues .Lack of specific quality and safety specifications in the regulations .On going import detentions involving color Synthetic Raw Materials Under Pressure • Increasing concern and Central Government activity around chemical industry in China and India • Availability of raw materials has become much more volatile • Cost are increasing and needs for environmental controls become more wide spread • Cost could double for synthetic colors over next 2 – 3 years • Natural colors may become an attractive alternatives from a supply security and environmentally responsible standpoint.

  • STAINING TECHNIQUES — Staining Is an Auxiliary Technique Used in Microscopy to Enhance Contrast in the Microscopic Image
    STAINING TECHNIQUES Staining is an auxiliary technique used in microscopy to enhance contrast in the microscopic image. Stains or dyes are used in biology and medicine to highlight structures in biological tissues for viewing with microscope. Cell staining is a technique that can be used to better visualize cells and cell components under a microscope. Using different stains, it is possible to stain preferentially certain cell components, such as a nucleus or a cell wall, or the entire cell. Most stains can be used on fixed, or non-living cells, while only some can be used on living cells; some stains can be used on either living or non-living cells. In biochemistry, staining involves adding a class specific (DNA, lipids, proteins or carbohydrates) dye to a substrate to qualify or quantify the presence of a specific compound. Staining and fluorescence tagging can serve similar purposes Purposes of Staining The most basic reason that cells are stained is to enhance visualization of the cell or certain cellular components under a microscope. Cells may also be stained to highlight metabolic processes or to differentiate between live and dead cells in a sample. Cells may also be enumerated by staining cells to determine biomass in an environment of interest. Stains may be used to define and examine bulk tissues (e.g. muscle fibers or connective tissues), cell populations (different blood cells) or organelles within individual cells. Biological staining is also used to mark cells in flow cytometry, flag proteins or nucleic acids on gel electrophoresis Staining is not limited to biological materials, it can also be used to study the morphology (form) of other materials e.g.

Received: 23 December 2019; Accepted: 4 February 2020; Published: 10 February 2020 Abstract: Clean water is a vital element for survival of any living creature and, thus, crucially important to achieve largely and economically for any nation worldwide. However, the astonishingly fast trend of industrialization and population growth and the arisen extensive water pollutions have challenged access to clean water across the world. In this regard, 1.6 million tons of dyes are annually consumed. Thereof, 10%–15% are wasted during use. To decolorize water streams, there is an urgent need for the advanced remediation approaches involving utilization of novel materials and technologies, which are cost and energy efficient. Nanomaterials, with their outstanding physicochemical properties, can potentially resolve the challenge of need to water treatment in a less energy demanding manner. In this review, a variety of the most recent (from 2015 onwards) opportunities arisen from nanomaterials in different dimensionalities, performances, and compositions for water decolorization is introduced and discussed. The state-of-the-art research studies are presented in a classified manner, particularly based on structural dimensionality, to better illustrate the current status of adsorption-based water decolorization using nanomaterials. Considering the introduction of many newly developed nano-adsorbents and their classification based on the dimensionality factor, which has never been employed for this sake in the related literature, a comprehensive review will be presented.

McPhee Received: 22 June 2016; Accepted: 19 July 2016; Published: 22 July 2016 Abstract: Synthetic and bioinspired metalloporphyrins are a class of redox-active catalysts able to emulate several enzymes such as cytochromes P450, ligninolytic peroxidases, and peroxygenases. Their ability to perform oxidation and degradation of recalcitrant compounds, including aliphatic hydrocarbons, phenolic and non-phenolic aromatic compounds, sulfides, and nitroso-compounds, has been deeply investigated. Such a broad substrate specificity has suggested their use also in the bleaching of textile plant wastewaters. In fact, industrial dyes belong to very different chemical classes, being their effective and inexpensive oxidation an important challenge from both economic and environmental perspective. Accordingly, we review here the most widespread synthetic metalloporphyrins, and the most promising formulations for large-scale applications.

Herein the validation of a 2006 LC-UV/Visible method for a limited number of such dyes in chilli powder has been reviewed and a new multi-dye general screening method is proposed. Both methods apply 90:10 acetonitrile:acetone extraction at 40C and reverse phase gradient elution liquid chromatography (LC) with UV/Visible detection. No clean-up, other than filtration, and no concentration stage is required. Of the 23 dyes investigated for the new screening method in chilli powder, canned chicken in a curry sauce, fennel, palm oil, paprika and turmeric, 19 are adequately dealt with by the new method. Recovery, linearity and within-day precision data are reported and although limits of detection (LOD) were not extensively investigated they appear to be consistent with previous LOD data. The dyes covered by the proposed general screening method are Orange II, Sudan I–IV, Sudan Black B, Sudan Red 7B, Sudan Red G, Methanil yellow, Dimethyl yellow, Auramine O, Bixin, Fast Garnett GBC, Rhodamine B, Oil Orange SS, Orange G, Sudan Orange G, Naphthol Yellow, Acid Red 73, Toluidine Red, Sudan Red B, and Para Red.
