    Definitions

    Food colouring is any substance, liquid or powder,

    that is added to food or drinkto change its colour.

    Flavour enhancers are used to bring out the flavourin

    a wide range of foods without adding a flavour of their

    own.

    Preservative food additives can be used alone or in

    conjunction with other methods of food preservation.

    Preservatives may be antimicrobial preservatives,

    which inhibit the growth of bacteria or fungi, includingmold, orantioxidants such as oxygen absorbers, which

    inhibit the oxidation of food constituents

    7/40

    An antioxidant is a molecule capable of inhibiting the

    oxidation of other molecules.

    An emulsifier (also known as an emulgent) is a substancewhich stabilizes an emulsion by increasing its kinetic

    stability.

    Gellings orThickening agents are substances which, when

    added to an aqueous mixture, increase its viscosity withoutsubstantially modifying its other properties, such as taste.

    They provide body, increase stabilility, and improve

    suspension of added ingredients.

    Acidulants are additives that give a sharp taste to foods.They also assist in the setting of gels and to act as

    preservatives.

    Stabilizers are an indispensable substance in

    food items that categorised as food additives.When added to the food items, they smoothen

    the texture of the food and give a definite

    body to the food. Food stabilisers are added

    in relatively small amount which aggravate

    the effect of emulsifiers.

    Sweeteners: This category of nonnutritive,

    high-intensity sugar substitutes includes

    aspartame, acesulfane-k and saccharin .

    Leavenigs: A leavening agent is any one of a

    number of substances used in doughs and

    batters that cause a foaming action which

    lightens and softens the finished product

    EmulsufiersSoy lecithin:Soy lecithin has been found to beeffective in various food and industrial applications

    due to its emulsifying properties. high doses have

    been seen to cause various problems and side effects

    which include gastrointestinal problems, diarrohea,

    either weight gain or loss of appetite, rashes,

    headache, nausea, dizziness, vomiting and unpleasant

    body odour and bad breath.

    E 472b: Esters of mono and diglycerides

    Used to give emulsions their stability and the requiredviscosity. They are now currently included in low calorie

    spreads, peanut butter and ice cream to control their

    texture, starch based foods such as macaroni, noodles,

    potato products and in the bakery industry.There is

    concern in some quarters that may be carcinogenic.

    Flavour enhancers

    Monosodium glutamate (MSG E 621): It is often used in

    fast food, snack foods, tinned and frozen food.

    MSG is safe for most people when eaten at customary

    levels. However, it also said that, some people may have an

    MSG intolerance that causes MSG symptom complex

    and/or a worsening of asthmatic symptoms.

    Didodium Guanylate: Disodium guanylate is produced

    from dried fish or dried seaweed and is often added to instant

    noodles, potato chips and other snacks.Disodium guanylate is

    not safe for babies under twelve weeks, and should generally

    be avoided by asthmatics and people with gout,

    Jellings

    E 407: Carrageenans or carrageenins are a family of linearsulfated polysaccharides which are extracted from red seaweeds.

    The Joint FAO expert committee on food additives states "that

    based on the information available, it is inadvisable to use

    carrageenan in infant formulas.There is evidence that degraded

    carrageenan (poligeenan) may cause ulcerations in the gastro-

    intestinal tract and gastro-intestinal cancer.

    E 401:Alginic acid, also called algin oralginate, is an anionic

    polysaccharide distributed widely in the cell walls of brown

    algae, where it, through binding water, forms a viscous gum. In

    extracted form it absorbs water quickly. In March, 2010

    researchers at Newcastle University announced that dietary

    alginates can reduce human fat uptake by more than 75%.

    Sodium alginate

    Food colours

    E 150d:Caramel color or caramel colouring is a soluble foodcolouring. It is made by a carefully controlled heat treatment of

    carbohydrates in a process called caramelization. Caramel

    colouring may be derived from a variety of source products that

    are themselves common allergens.So, people with known

    sensitivities or allergies to food products are advised to avoid

    foods including generic caramel colouring.

    E 160 a: Carotene, alpha-, beta-, gamma-Carotene colouringfades on exposure to light.

    Typical products include fruit juices and squashes, cakes,

    desserts, butter and margarine.

    E 171:T

    itanium dioxide.T

    itanium dioxide may beused in food to give opacity. No adverse effects are

    known, and the compound is chemically inert.

    E 141: Copper complexes of chlorophyll. Olive colour,

    extracted from plants, no adverse effects are known

    when used in foods.

    Acidul

    antsE 338: Phosphoric acid, used in many soft drinks

    (primarily cola), has been linked to lower bone density

    in epidemiological studies.

    E 330: citric acid is a colourless, crystalline organiccompound, belonging to the family of carboxylic

    acids. Its use as a food additive is wide and varied.

    Recorded problems are that it can be a local irritant

    and in large amounts can cause teeth erosion.

    E 331: Ascorbic Acid. Ascorbic acid and its sodium,

    potassium, and calcium salts are commonly used as

    antioxidant food additives.

    SweetenersE 952:Sodium cyclamate is an artificial sweetener. It is3050 times sweeter than sugar, making it the least potent

    of the commercially used artificial sweeteners

    E 950:Acesulfame K is 180-200 times sweeter thansugar.Critics say acesulfame potassium has not been

    studied adequately and may be carcinogenic.

    E 951:Aspartame (or APM) is an artificial, non-

    saccharide sweetener used as a sugar substitute in somefoods and beverages. A 2007 medical review on the

    subject concluded that "the weight of existing scientific

    evidence indicates that aspartame is safe at current levels

    of consumption as a non-nutritive sweetener

  • 8/6/2019 Spanish Presentation on Sweets Ingredients (1)

    29/40

    Our students carried out a

    survey

    They studied sweets consumption among students

    from 14 to 17 years old

    The results were the following ones:
