The Safety Evaluation of Food Flavouring Substances
Toxicology Research View Article Online REVIEW View Journal The safety evaluation of food flavouring substances: the role of metabolic studies Cite this: DOI: 10.1039/c7tx00254h Robert L. Smith,a Samuel M. Cohen, b Shoji Fukushima,c Nigel J. Gooderham,d Stephen S. Hecht,e F. Peter Guengerich, f Ivonne M. C. M. Rietjens,g Maria Bastaki,h Christie L. Harman,h Margaret M. McGowenh and Sean V. Taylor *h The safety assessment of a flavour substance examines several factors, including metabolic and physio- logical disposition data. The present article provides an overview of the metabolism and disposition of flavour substances by identifying general applicable principles of metabolism to illustrate how information on metabolic fate is taken into account in their safety evaluation. The metabolism of the majority of flavour substances involves a series both of enzymatic and non-enzymatic biotransformation that often results in products that are more hydrophilic and more readily excretable than their precursors. Flavours can undergo metabolic reactions, such as oxidation, reduction, or hydrolysis that alter a functional group relative to the parent compound. The altered functional group may serve as a reaction site for a sub- sequent metabolic transformation. Metabolic intermediates undergo conjugation with an endogenous agent such as glucuronic acid, sulphate, glutathione, amino acids, or acetate. Such conjugates are typi- Received 25th September 2017, cally readily excreted through the kidneys and liver.

METABOLISM OFF-FLAVOR IN MAPLE SYRUP Part II: Remediation of metabolism off-flavor in maple syrup Abby K. van den Berg1, Timothy D. Perkins1, Mark L. Isselhardt1, Mary An Godshall2 and Steven W. Lloyd3 INTRODUCTION 'Metabolism' is an off-flavor described as 'earthy to bitter' which significantly reduces the economic value of maple syrup (Perkins et al. 2006). It periodically occurs in syrup simultaneously over a wide geographic range, and in some years can affect up to 25% of the total annual maple syrup crop (Perkins and van den Berg in press). Research on metabolism at the University of Vermont Proctor Maple Research Center (PMRC) had two main objectives: 1) to identify the primary compound or compounds responsi- ble for metabolism off-flavor in maple syrup, and 2) to develop a technique maple pro- ducers and packers could use to effectively remediate the flavor of metabolized maple syrup. The primary compound associated with metabolism off-flavor was identified as 2,5- dimethylpyrazine (2,5-DMP) (van den Berg et al. 2009a). 2,5-dimethylpyrazine is a nat- urally-occurring volatile flavor compound found in a variety of heat-processed foods, including roasted beef, cocoa, bacon, and coffee (Maga 1992), as well as maple syrup (Alli et al. 1992, Akochi-K. et al. 1997). In maple syrup with metabolism off-flavor, how- ever, 2,5-DMP occurs in much greater concentrations (up to 40 times greater) than in syrup without the off-flavor (van den Berg et al. 2009a). In practice, producers and packers attempt to blend out the off-flavor by mixing metabolized syrup in with good-tasting syrup. -
Vulcanization & Accelerators
Vulcanization & Accelerators Vulcanization is a cross linking process in which individual molecules of rubber (polymer) are converted into a three dimensional network of interconnected (polymer) chains through chemical cross links(of sulfur). The vulcanization process was discovered in 1839 and the individuals responsible for this discovery were Charles Goodyear in USA and Thomas Hancock in England. Both discovered the use of Sulfur and White Lead as a vulcanization system for Natural Rubber. This discovery was a major technological breakthrough for the advancement of the world economy. Vulcanization of rubbers by sulfur alone is an extremely slow and inefficient process. The chemical reaction between sulfur and the Rubber Hydrocarbon occurs mainly at the C = C (double bonds) and each crosslink requires 40 to 55 sulphur atoms (in the absence of accelerator). The process takes around 6 hours at 140°C for completion, which is uneconomical by any production standards. The vulcanizates thus produced are extremely prone to oxidative degradation and do not possess adequate mechanical properties for practical rubber applications. These limitations were overcome through inventions of accelerators which subsequently became a part of rubber compounding formulations as well as subjects of further R&D. Following is the summary of events which led to the progress of ‘Accelerated Sulfur Vulcanization'. Event Year Progress - Discovery of Sulfur Vulcanization: Charles Goodyear. 1839 Vulcanizing Agent - Use of ammonia & aliphatic ammonium derivatives: Rowley. 1881 Acceleration need - Use of aniline as accelerator in USA & Germany: Oenslager. 1906 Accelerated Cure - Use of Piperidine accelerator- Germany. 1911 New Molecules - Use of aldehyde-amine & HMT as accelerators in USA & UK 1914-15 Amine Accelerators - Use of Zn-Alkyl Xanthates accelerators in Russia. -
Food Words Describing Taste and Flavor
Food Words Describing Taste and Flavor Look thorough this list and write down 15-20 you think would help your descriptive writing for your restaurant review paper. Make sure you are suing the word correctly and in its correct form. Acerbic is anything sour, bitter or sharp - cutting, caustic, acid, mordant, barbed, prickly, biting, pointed. The opposite flavor would be mild, sweet, or honeyed. Acid or Acidic food can be sharp, tart, sour, bitter. Just the opposite of sweet, sugary, honey. Acrid taste can be considered pungent, bitter, choking, sharp, unpleasant, harsh - sharp, cutting, caustic, bitter, vitriolic, mordant, trenchant - sour, tart, sharp, biting, acerbic. Aftertaste is the trace, hint, smack, relish, savor food leaves behind. Ambrosia is the food of the gods, and epicurean delight, food fit for a king, delicacy, heavenly spread, gastronomical delight, some apply this term to the pièce de résistance in a meal. Ambrosial is, therefore, fit for the gods, delectable, mouthwatering, heavenly, savory, delicious, tasty, toothsome, divine. It is not distasteful or disgusting at all. Appealing food is attractive, tempting, interesting, pleasing, alluring, likable, engaging, charming, fascinating, glamorous. It is never repulsive, disgusting, or repellent. Appetite is the hunger, craving, desire, taste, ravenousness, sweet tooth, thirst, penchant, or passion we experience. When we have an appetite for something, we don't find it repulsive or distasteful. Appetizer is the tidbit, snack, starter, hors d'oeuvre, finger food, dip, cold cuts, kickshaw, olives, anchovies - canapés, dim sum, aperitif, rollmops, antipasto, crudités we might have to open a meal. Appetizing is everything we find appealing, mouth-watering, delectable, savory, delicious, palatable, inviting, tantalizing, toothsome, luscious, tempting, tasty, enticing. -

2021 Flavor Trends
2021 FLAVOR TRENDS 2021 Flavor Trends 2020 reintroduced many to their home kitchens, it was a year of asking for family recipes, baking bread, and experimenting with new avors. As we look ahead to 2021, undoubtedly there is no better time to innovate around avor. We will reinvigorate classic comfort foods, travel through our tastebuds, and focus on foods that promote immunity and health. Comfort Foods At Signature Sauces, comfort foods are our forte. We have multiple foodservice partners that have mastered the BBQ game and their menus proved success throughout the pandemic. Nothing says down home comfort more than a plate of barbequed meat and a bowl of hearty mac and cheese. Not to mention, our company’s humble beginning started with producing pasta sauce recipes that had been handed down through generations. Those recipes are authentic, homemade, and will warm your belly and your heart. As we refocus on the comforts of Grandma’s Sunday Gravy, we nd ourselves redening authenticity. These recipes originated in Italy, so why are we not using Italian tomatoes? After some dedicated R&D time, we realized the Italian tomatoes are rich in avor and lower in sodium. So, in this instance we produced a comfort food that became healthi- er, which is not always easily achieved. Healthy Ingredients As families continue to cook more often at home, the reality of the foods we eat and how it aects our overall health becomes more apparent. We have all been forced to slow down, spend time at home, and eat simply. As we battle this pandemic one common thread remains prominent- if we are unhealthy, we are more apt to contract the virus and ultimately face a harder battle in our healing process. -
