3Origin and Suitability of Colors : 1. Food coloringOrigin and Suitability of Colors :Serious poisoning occurred from the use of such dangerous inorganic pigmentsExample : copper sulfate, copper arsenite, red lead, cinnabarSimilar colors such as : red oxide of iron, ultramarine, thitanium dioxide (which are still used occasionally) were harmless ???Organic dyes were synthesized and can be applied in food manufacture, as well as to textiles, plastics, ink and non edible comodities.
41. Food coloring Definition : Any substance that is added to food or drink to improve or change its color.Function :Offsetting color loss due to light, air, extremes of temperature, moisture, and storage conditions.Masking natural variations in color.Enhancing naturally occurring colors.Providing identity to foods.Protecting flavors and vitamins from damage by light.Decorative or artistic purposes such as cake icing.

152. flavoring Flavor Definition Complex sensation induced by chemical compounds that are present in food or drink and are in equlibrium at time of ingestion. Simultaneous appreciation of stimuli receptors of taste on the tongue and smell in the nasal cavity, and general pain, feeling, and temperature receptors located throughout the mouth and throath (Heath, 1981)Flavor is important in Confectionery Factor that has no chemical or physiological basis for inclusion in the diet, but without it there would likely be no confectionery industry.
162. flavoring Definition : The sensory impression of a food or other substance, and is determined mainly by the chemical senses of taste (tongue) and smell (nasal cavity). The taste of food is limited to sweet, sour, bitter, salty, and savory.Function :- Impress sense of taste and smell- Enhance natural/original flavor in food product- Offsetting flavor loss due to food processing
17FlavorFlavor preference and acceptance or rejection of foods, and confectionery products are no exception, display enormous variability, depending on such factor : ethnic origins education upbringing age environmentFlavor - Odor - Smell ????
18Flavoring Materials Naturally occurring plant materials Herbs, spices, vanilla, fruits, nuts, aromatic vegetables.Derivate from Natural Substance Extracts, essences, essential Oils, oleoresins, fruit juices, concentrates.Flavor Isolate Eugenol from clove leaf oil, citral from lemon grass oil.Synthetics by chemicall ex : vanillin from wood ligninArtificial aromatic chemicals ex : gamma undecalactoneFlavor enhancers ex : maltolTaste modifiers ex : salt, sugar, organic acid.
19Flavoring IngredientFruit flavor mixed with synthetic flavor (improve original flavor, more stabile, resistant to high temperature).Caramel, honey, brown sugar, maple sugar, chocolate, milk, cream, butter = specific contributor of candy flavor.Type :Natural flavor : Vanilla, citrus oil, essential oilFruit flavor :Bananas, apples & berries, etc.Acid :Citric acid, tartaric acid or volatile oil and aromatic chemicals.
20Synthetics Flavor Ex. Formula of Apple Flavor : Geranilvalerat 10% Geranil n-butirat 8%Geranil propionat 8%Linalil format 10%Isoamilvalerat 15%Vanilin 8%Alylkaprilat 6%Geranil aldehid 5%Asetil dehida 6,5%Metil siklopentonolon valerat %Alfamentil furil akroelin 2%Isoamil butirat 13,5%
213. acidulants Definition Any substance that is added to food or drink to give or improve sour taste and odour. Additives that give a sharp taste to foods. They also assist in the setting of gels (consistency) and to act as preservatives.Many natural foods are acidic.Ex : oranges, lemons, apples, tomatoes, cheese and yoghurt contain natural acids, such as citric acid, that give them their characteristically sharp taste.
26ACID STRENGTHThis acid strength value will be different for each acid.The weaker the acid the higher level required to lower the pH.
27ACID STRENGTHAcid strength values with this model system at pH values from 2.5 to 4.0
28PHOSPHATE Function : Application in Food: 2. Suplement 3. Emulsifying 1. Chelator2. Suplement3. EmulsifyingApplication in Food:Cola, root beer, sarsaparilla, carbonated beverages.Clarifying & acidify collagenAcidify jam & jellies
29CITRIC ACID Naturally present in lemon juices. Produced by fermentation “molds” on sugar syrups or molasses.High Solubility (50% in water) confectioneryFunction :- Maintain colour, aroma, vitamins of canned food- Control pH in confectionery- chelator, antioxidantHard candy prefer to citric acid powder
31Tartaric Acid Prepared from potassium hydrogen tartrate Chelator Generally used in Baking powderApplication : butter, jam, jellyFlavor in candy & confectionery (Hard candies)
32ACETIC ACID Application in Food : Mayonnaise, sauce, pickle. Function :Control pH, flavor & shelf life.
33Ascorbic Acid Rarely used as acidulants Strong reductor Antioxidant Stabilized by citric acid
344. emulsifier Definition : Substance which stabilizes an emulsion by increasing its kinetic stability.One class of emulsifiers is known as surface active substances or surfactants.Type :Lecithin (egg yolk, soy), honey, and mustard, where a variety of chemicals in the mucilage surrounding the seed hull act as emulsifiers, sodium stearoyl lactylate.
35Le ch i t i n Function : Improve palatability Improve visibility Stabilize the emulsion (flavor-oil)Inhibit the separation between product and its constituents (ex : oil)Control grain and crystalFunction :Control of viscositiesSlab releasing agentDecelerate of candy ossification , ex : starch base candyInhibit of fat bloomDecelerate of Glaze less
36Emulsifier in Food Oil-in-water (o/w) emulsions are common in food. Vinaigrette – vegetable oil in vinegar; if prepared with only oil and vinegar (without an emulsifier), yields an unstable emulsion.Mayonnaise – vegetable oil in lemon juice or vinegar, with egg yolk lecithin as emulsifier.Hollandaise sauce – similar to mayonnaise.Crema in espresso – coffee oil in water (brewed coffee), unstable.
375. antioxidant Definition Molecule capable of slowing or preventing the oxidation of other molecules.Oxidation a chemical reaction that transfers electrons from a substance to an oxidizing agent.Oxidation produce free radicals, which start chain reactions that damage cells.Antioxidants terminate these chain reactions by removing free radical intermediates, and inhibit other oxidation reactions by being oxidized themselves.
38Food Antioxidants Antioxidants are often reducing agents such as 1) Thiols2) Ascorbic acid or polyphenols.Water soluble Ascorbic acid, glutathione, lipoic acid, uric acidLipid Soluble Carotenes, ubiquinol, tocopherol
39Antioxidant Type : Propil Galate BHA BHT Function : Inhibit oxidative breakdown of fat = extending shelf life candy
406. Gelatinizing Definition : Substances that form gels and foams or act as stabilizers.Some of these may be used as glazing coating.Increase viscosity, provide body, increase stability, and improve suspension in aqueous solution.Frequently are based on :polysaccharides (starches, vegetable gums, pectin, alginate, karegenan), or proteins.
