Morpholine: a Glazing Agent for Fruits and Vegetables Coating/Waxing (IJSTE/ Volume 2 / Issue 11 / 119) with Glazing Agent
IJSTE - International Journal of Science Technology & Engineering | Volume 2 | Issue 11 | May 2016 ISSN (online): 2349-784X Morpholine: A Glazing Agent for Fruits and Vegetables Coating/Waxing Rupak Kumar Suman Kapur Research Scholar Senior Professor Department of Biological Sciences Department of Biological Sciences BITS-Pilani, Hyderabad Campus, Hyderabad-500078, India BITS-Pilani, Hyderabad Campus, Hyderabad-500078, India Abstract The saying “an apple a day keeps the doctor away” probably gives us the impression that apples are the healthiest fruits. But besides the fact that it rhymes, does it really have no adverse effects if we eat a bright red wax coated apple every day? Morpholine (C4H9NO) is a chemical used as emulsifier in the preparation of wax coatings for fruits and vegetables to help them last longer and remain fresh even during prolonged transit. Morpholine oleate is added to wax as it enables spreading wax in water based liquid for use as a protective coating to prevent contamination by pests and diseases. Morpholine alone does not appear to pose a health concern because morpholine itself is neither a carcinogen nor a teratogen and does not cause chronic toxicity. However, it is a precursor for potent carcinogenic nitrosamines. Keywords: Carcinogen, Emulsifier, Morpholine, Teratogen, Wax Coating ________________________________________________________________________________________________________ I. INTRODUCTION The practice of fruit/vegetable coating was accepted long before their associated chemistries were understood, and are still practiced till date. The first wax coating was applied to citrus fruits in 12th-13th centuries in China. Today, it has expanded rapidly for retaining quality of a wide variety of foods/vegetables, with total annual revenue exceeding $100 million [1]. -

Rosin - Wikipedia, the Free Encyclopedia Page 1
Rosin - Wikipedia, the free encyclopedia Page 1 Rosin From Wikipedia, the free encyclopedia Rosin , also called colophony or Greek pitch (Pix græca ), is a solid form of resin obtained from pines and some other plants, mostly conifers, produced by heating fresh liquid resin to vaporize the volatile liquid terpene components. It is semi-transparent and varies in color from yellow to black. At room temperature rosin is brittle, but it melts at stove-top temperatures. It chiefly consists of various resin acids, especially abietic acid.[1] The term "colophony" comes from colophonia resina or "resin from the pine trees of Colophon," an ancient Ionic city. A cake of rosin, made for use by violinists, used here for Contents soldering 1 Uses 1.1 Pharmaceutical 2 Production 3 Properties 4 Sources 5 See also 6 Sources 7 Notes 8 External links Uses Rosin is an ingredient in printing inks, photocopying and laser printing paper, varnishes, adhesives (glues), soap, paper sizing, soda, soldering fluxes, and sealing wax. Rosin can be used as a glazing agent in medicines and chewing gum. It is denoted by E number E915. A related glycerol ester (E445) can be used as an emulsifier in soft drinks. In pharmaceuticals, rosin forms an ingredient in several plasters and ointments. In industry, rosin is a flux used in soldering. The lead-tin solder commonly used in electronics has about 1% rosin as a flux core helping the molten metal flow and making a better connection by reducing the refractory solid oxide layer formed at the surface back to metal. It is frequently seen as the burnt or clear residue around new soldering. -
Chemical and Technical Assessment 65Th JECFA
Chemical and Technical Assessment 65th JECFA BEESWAX Chemical and Technical Assessment (CTA) First draft prepared by Paul M. Kuznesof, Ph.D.∗ Reviewed by D. Brian Whitehouse, Ph.D. 1 Summary Beeswax (INS No. 901) consists primarily of a mixture of esters of fatty acids and fatty alcohols, paraffinic hydrocarbons, and free fatty acids; minor amounts of free fatty alcohols are also present. Two types of beeswax are marketed: yellow beeswax (C.A.S No. 8006-40-4) and white beeswax (C.A.S. No. 8012-89-3). Yellow beeswax is a yellow or light-brown solid that is somewhat brittle when cold and presents a characteristic odour of honey. White beeswax is a white or yellowish white solid (thin layers are translucent) having a characteristic, but faint, odour of honey. Beeswax is obtained from the honeycombs of bees (Apis mellifera L., Fam. Apidae) after removal of the honey. The combs are melted with hot water, steam, or solar heat. After removing the insoluble impurities, the liquid wax is cast into cakes for further purification to obtain food-grade yellow beeswax. Bleaching the latter with e.g. hydrogen peroxide, sulfuric acid or sunlight, yields white beeswax. Beeswax consists primarily of five main groups of components, namely: 1. Free fatty acids (typically 12-14%), most of which are saturated (ca. 85%) and have a chain length of C24-C32. 2. Free primary fatty alcohols (ca. 1%) with a chain length of C28-C35. 3. Linear wax monoesters and hydroxymonoesters (35-45%) with chain lengths generally of C40- C48. The esters are derived almost exclusively from palmitic acid, 15-hydroxypalmitic acid, and oleic acid. -

Do-It-Yourself HVAC Apprentice Contest Basic Guidelines for Planning an Apprentice Contest
PHCC Educational Foundation Do-It-Yourself HVAC Apprentice Contest Basic Guidelines for Planning an Apprentice Contest 1. Find volunteers! Members, teachers, technicians and inspectors all make good volunteers. 2. Designate a chairman or coordinator to run the contest. The role of chairman or coordinator can be done by anyone who is willing to volunteer and dedicate the time it takes to plan and administer the contest. He or she should have some HVAC background as well as the ability to answer technical questions about the contest. The chairman/coordinator is responsible for delegating all necessary job tasks. His/her decisions are final. Normally, the chairman/coordinator is the state or local apprenticeship committee chairman or an instructor at an apprentice school. 3. Set up a timeline or schedule of events. 4. Design the test and/or contest you will use. A sample contest has been provided at the end of this book. 5. Make a list of contest rules for the apprentices to follow. Provide this information with the registration form. 6. Make an agenda for the apprentices to follow. Include registration deadlines, time to arrive at the contest site and time of the awards presentation. 7. Find students to compete. Ideally, they should be PHCC apprentices and/or SkillsUSA students. You can have as few as three and as many as you feel you can handle. 8. Find a location for the contest. Some suggestions include outside under a tent, inside an exhibition hall, in a member’s shop or at the apprentice school. If you use an exhibition hall, please note that you may have to obtain a permit from the local fire marshal. -
About Wiring Color
About Wiring Color There is no official industry standard for wiring colors. However, the majority of manufacturers follow the common practices for installation. The following information is strictly for reference. Please be advised that the technician who did the previous installation of the thermostat may not incorporate conventional color coding for various reasons. Red for the R terminal. The R terminal is the power. This comes from the transformer usually located in the air handler for split systems but you may find the transformer in the condensing unit. For this reason, we advise turning off the power before adjusting the thermostat's wiring. Red for the RH terminal. RH – The RH terminal is designated for the power for heating when two transformers are used. See RC below for an explanation for the cooling. It should be noted that a jumper can be installed between RC and RH for a heating and cooling system equipped with a single transformer. It should be noted that a jumper wire can be installed between RC and RH for a heating and cooling system equipped with a single transformer. Red for the RC terminal. The RC terminal is designated to the cooling power source. Some HVAC systems consist of two transformers, one for cooling and the other for heating. In this case the power from the transformer in the air conditioning system would go to the thermostat terminal RC. It should be noted that a jumper wire can be installed between RC and RH for a heating and cooling system equipped with a single transformer. -

Decco Communication on Shellac Resin
Decco Communication on Shellac Resin 1 BACKGROUND Some supermarkets in Australia have inquired about the quality of shellac resin used as an ingredient in apple wax coatings. Apple packers, who are EE Muir’s customers, have in turn asked EE Muir to provide documentation on the quality of shellac and manufacturing practices used by Decco. Below are a number of documents and explanations that Decco is providing to EE Muir in support of Decco’s quality and manufacturing practices. 2 WHAT IS NATURAL SHELLAC RESIN Shellac is a natural gum resin secreted by the lac beetle (laccifer lacca) which lives on trees in tropical and subtropical regions. The natural gum resin is harvested from the trees and then processed and refined into flakes and powders of pure natural shellac resin. 3 SHELLAC AND ITS USES Natural shellac resin has unique properties and is used in various applications such as: Fruit coatings, Confectionery (Candy & Chocolates coating), Pharmaceutical (Tablets coatings) as well as several non- food segments. Shellac is used as a 'wax' coating on citrus fruit to prolong its shelf/storage life. It is also used to replace the natural wax of the apple, which is removed during the cleaning & washing process. In these applications, the wax coating prevents moisture loss (shrinking, shriveling of the fruit) and preserves the textural and eating quality of the fruit. When used for this purpose, it has the food additive E number E904 which is recognized and adopted worldwide. Shellac is also used as a glazing agent on pills, food, chocolate & candies, in the form of pharmaceutical glaze or, confectioner's glaze.
