SWEETENERS

SWEETENERS A sugar substitute is a food additive that duplicates the effect of sugar in taste , usually with less food energy . Some sugar substitues are natural and some are synthetic . Natural sweeteners : Typically chemicals are separated from the plant. Some of these substances can be used instead of sugar even though they contain less energy than that of the same weight sweeter than sugar .

SWEETENERS Sorbitol ( Glucitol ): It can be obtained by reduction of glucose, changing the aldehyde group to a hydroxyl group. Most sorbitol is made from corn syrup, but it is also found in apples, pears, peaches, and prunes . E code is 420.

SWEETENERS Stevia ( Genus ): E xtracted from the leaves of the plant species  Stevia rebaudiana . Stevia's taste has a slower onset and longer duration than that of sugar, and some of its extracts may have a bitter or licorice-like aftertaste at high concentrations.

SWEETENERS Glycerol ( Glycerine ):  is a simpl e sugar alcohol compound. It is a colorless, odorless, viscous liquid that is widely used in  drug formulations. In food and beverages, glycerol serves as a humectant, solvent, and sweetener, and may help preserve foods . E code is 422.

SWEETENERS Others Natural Sweeteners ; Xylitol (E967) Lactitol (E966) Maltitol (E965) Isomalt (E953) Thaumatin (E957)

SWEETENERS Artificial Sweeteners : They are obtained in the laboratory by synthesizing like natural sweetener agent . Usually contains zero or near zero amount energy ( calories ). Aspartame :  is an artificial, non-saccharide sweetener used as a sugar substitute in some foods and beverages. Aspartame is approximately 200 times sweeter than sucrose (table sugar). E code is 951.

SWEETENERS Acesulfame potassium : It is a low calorie sweeterner and knows organic syhntetic salt. It is used in the food during the cooking or baking . Uses : Gum , beverage , dry beverage mixes , gelatin desserts , puddings and cream .

SWEETENERS Saccharin : I s an artificial sweetener with effectively no foo d energy which is approximately 300 times as sweet as sucrose or table sugar, but has a bitter or metallic aftertaste, especially at high concentrations. It is used to sweeten products such as drinks, candies, cookies, medicines, and toothpaste. E number is 954.

SWEETENERS Other artificial sweeterners : Cyclamate (E952) Neohesperidine dihydrochalcone (E959) Sucralose (E955)

OTHER ADDITIVES Acidity Regulators : Inability to control the pH can cause growth of bacteria that could threaten health.So we need to use acidity regulator in the food product . Some of acidity regulators ;

E CODE NAME USES E260 ACETIC ACID butter , margarine, curry powder , cooking oil , processed cheese E263 CALCIUM ACETATE packed sweets E270 LACTIC ACID cheese , milk , meat , sauces and drinks E296 MALIC ACID konserve meyve, sebzeler ve bakliyat, reçeller, marmelatlar, donmuş sebzeler E297 FUMARIC ACID bread , fruit drinks , turta dolguları,wine jam , marmalade E330 CITRIC ACID fruit and vegetable ( especially lemon and linden ) non-alcoholic beverages E334 TARTARIC ACID bakery products , candy

EMULSIFIERS

EMULSIFIERS Mixing two substances, such as oil -in-water emulsifier to each other is called externally added agent to get a homogeneous appearance. What are the benefits of emulsifiers used in food products? Strengthens the internal structure of the Increases the consistency of the product , Increases the consistency of the product , According to product fluency, shape , Extend the shelf life of the product.

EMULSIFIERS

EMULSIFIERS Some common applications of emulsifiers ; Bread : It is possible to make bread without emulsifiers but the result is often dry, low in volume and easily stales. There are two types of emulsifiers used in bread: dough strengtheners (e.g. diacetyl tartaric acid esters (E472e) and sodium or calcium stearoyl-2-lactylate (E481, E482)) and dough softeners (e.g. mono- and di-glycerides of fatty acids (E471)).

EMULSIFIERS Ice-cream : Ice-cream is one of the most complex foods we encounter; both a foam and an emulsion it contains ice crystals and an unfrozen aqueous mix. Emulsifiers are added during the freezing process, to promote a smoother texture and ensure the ice-cream does not melt rapidly after serving. They also improve freeze-thaw stability. Mono and diglycerides of fatty acids (E 471), lecithin (E 322) and polysorbates (E 432, E 436) are commonly used in ice-cream production. All this applies to other desserts such as sorbet, milkshake, frozen mousse and frozen yogurt as well.

EMULSIFIERS Margarine: Emulsifiers give margarine the required stability, texture and taste. To ensure that the water droplets are finely dispersed in the oil phase, mono and diglycerides of fatty acids (E 471) and lecithin (E 322) are widely used. Citric acid esters of mono and diglycerides (E 472c) prevent the margarine from splattering while polyglycerol esters (E 477) and lactic acid esters make up for the good quality of margarine used to bake cakes, for example.

EMULSIFIERS Where are the areas of application of emulsifiers ? Salad dressings , Ready soups , Dairy products , Cosmetic and pharmaceutical production , Meat and meat made ​​materials .

ANTICAKING AGENTS

ANTICAKING AGENTS An anti-caking agent is an additive placed in powdered or granulated materials, such as table salt, to prevent the formation of lumps and provide to eas y packaging, transport, and consumption . The most important anti-caking agents ;

ANTICAKING AGENTS 1. E550( S odium S ilicate ): It can use in canned products(especially canned peach) and vanilla powder. 2. E551( S ilicon D ioxide ): I t improves clarity in beverages and reventing agglomeration keeping up 120% by weight of moisture.

ANTICAKING AGENTS 3. E533a(ii)(Magnesium T risilicate ): The additive is often employed by fast food chains to absorb fatty acids and remove impurities that form in edible oils during the frying process.

ANTICAKING AGENTS 4. E542 (Edible bone phosphate): Many dried substances contain edible bone phosphate as anticaking agents. It obtained from animal bone , such as pork and beef . B ecause of this, some religious groups do not use this item.

ANTIOXIDANTS

ANTIOXIDANTS Antioxidants are used for to prevent the effects like bad smell, bitter taste and brownish color which come up when the animal fats, vegetable oil and vitamins are combined with the atmospheric oxygen and free radicals.

ANTIOXIDANTS Antioxidants can also be produced in the body or taken from outside. Many vegetables and fruits,vegetable oils,white and red meat,fish,cereals,nuts and walnuts are natural antioxidant source . A,C,E vitamins and Selenium are the most important antioxidants taken from outside .

ANTIOXIDANTS L- A scorbic Acid (Vitamin C): E code is E300 and molecular formula is C 6 H 8 O 6 . It is obtained from bacterial fermentation of glucose and also is found some vegetables and fruits such as lemon , orange , kiwi , strawberry,cabbage and artichoke.When meat products,vegetables - fruit products and breads is labeled E code,L-ascorbic acid lose Vitamin C properties and it uses antioxidant .

ANTIOXIDANTS L- Ascorbic acid (Vitamin C)

2. Vitamin E ( Tocopherols and Tocotrienols ): Vitamin E found in nature 2 form.They are t ocopherols and tocotrienols . Vitamin E is the most important cell antioxidant and it can transport cell membrane . With this feature,cell can live long time and resfresh itself . Also reduces the progression of the Alzheimer's disease . ANTIOXIDANTS

Tocopherols : Alpha, beta, gamma and delta forms show Vitamin E properties . Alpha tocopherols are the most active biologically , but delta tocopherols are the most active as an antioxidant . Tocopherols usually obtained from soya, wheat, rice, cottonseed , corn or synthetic ways . ANTIOXIDANTS

E307 (Alpha tocopherol ): Especially uses to prevent rancidity of fats . ANTIOXIDANTS
