INTRODUCTION

:

EDIBLE:- Something fit to be eaten; food or Fit to be eaten, especially by humans COATING :- A layer of a substance spread over a surface for protection or decoration

DIFFERNCE BETWEEN PACKING AND PACKAGING :

DIFFERNCE BETWEEN PACKING AND PACKAGING PACKING :- A packing material is a one which is used to wrap the individual unit Ex: Polyethylene cover used to wrap one munch chocolate. PACKAGING:- A packaging material is a one which is used wrap or hold the already wrapped units Ex: Paper box used to hold 55 munch as a box

HISTORY:

HISTORY Edible packaging have been used for centuries to protect foods and prevent moisture loss. The first recorded use was in china (southern china) in the12th century. later in England using lard or fats, called larding to prolong shelf life of meat products. Since the early to mid 20th century coatings have been used to prevent water loss and add shine to fruits and vegetables.

EDIBILE COATING(definition):

EDIBILE COATING (definition) An edible film or coating is simply defined as a thin continuous layer of edible material placed on food, or between the foods or food components. which can be eaten as a part of the whole food product.

PRINCIPLES OF FILM FORMATION:

PRINCIPLES OF FILM FORMATION 1.Cohesive forces between polymers molecules: Here cohesive forces between same polymer molecules are responsible for barrier properties of filme . . 2.Adhesive forces between film & substrate: Here adhesive forces between film & substrate are responsible for formation of intact

MATERIALS USED:

MATERIALS USED Materials which can be used for manufacturing the edible packaging materials: Protein-based : Gluten - Soy Collagen - Casein Zein - Whey protein Polysaccharide-based : Cellulose - Chitosan Alginate - Starch Pectin - Dextrin

PowerPoint Presentation:

Lipid-based: Waxes Fatty acids These are the main ingredients for edible packaging materials. In addition to them some antimicrobial agents , Plasticizers and thickening agents are also used.

METHODS OF COATING :

METHODS OF COATING 1. Dipping 2. Dripping 3. Panning 4. Spraying 5. Fluidized-bed coating 6. Foaming

USE OF EDIBLE COATING :

USE OF EDIBLE COATING Reduce water loss Reduce gas diffusion Improve appearance (e.g., gloss) Improve structural properties (hold it together) Inhibit transfer of moisture and oxygen Carry food additives Reduce loss of volatile flavors & aromas Enhance nutritive value of food Reduced mold growth

PowerPoint Presentation:

Chitosan solution Damaged surface Molded surface Coated fruit Fresh fruit

ROLE OF EDIBLE FILMS AND COATING:

ROLE OF EDIBLE FILMS AND COATING Antimicrobial agents : Incorporating antimicrobial compounds into edible films or coatings provides a novel way to improve the food safety and shelf life of ready-to-eat foods Benzoic acid, Sodiumbenzoate , Sorbic acid , Pottassium sorbate , and Propionic acid

PowerPoint Presentation:

Antioxidants and antibrowning agents Antioxidants can be added into coating matrix to protect against oxidative rancidity , degradation and discoloration of certain foods. BHA, BHT Citric acid Ascorbic acid Nutrients, flavours and colorants : Edible films and coatings are excellent vehicles to enhance the nutritional value of food . by addition of vitamins and minerals. Also different types of colors & flavors are added to improve the appearance and taste of food.

SAFETY AND HEALTH ISSUES:

SAFETY AND HEALTH ISSUES An edible film to be used in food should be generally recognized as safe (GRAS) by the FDA. If the material cannot be demonstrated to be GRAS, then manufacturer must submit a food additive petition to the FDA. There should be a declaration about the type of edible materials some individuals are allergic to certain polymers.

ADVANTEGES OF EDIBLE FILM:

ADVANTEGES OF EDIBLE FILM Environment friendly, as fully consumed or biodegradable, Reduce the waste & solid disposal problem. Enhances Organoleptic properties like color, appearance etc Enhances nutritional values by supplementation Individual packaging is possible for fruits like strawberry.

PowerPoint Presentation:

Film can work as carrier anti microbial or antioxidant agents Reduce the cost of utilizing by-products. E.g. Whey

DRAWBACKS OF EDIBLE COATINGS :

DRAWBACKS OF EDIBLE COATINGS The edible wraps would not be used alone where unsanitary conditions during food handling can occur The new wraps are more expensive than synthetic packages. However, developers believe the nutritional and environmental advantages will justify the increased cost

PowerPoint Presentation:

They would be used to wrap foods inside a secondary synthetic package during food distribution and storage Development of off flavour . Poor mechanical properties

Say No to Plastic Bags :

Say No to Plastic Bags We realize that the pollution is increasing day by day due to plastic pollution because it does not destroy easily and take a long time to destroy. EFFECTS :- There are about 46,000 pieces of plastic floating in each square mile of our oceans. It is estimated that plastic kills up to 1 million sea birds, 100,000 sea mammals and countless fish each year.

PLEDGE:- :

PLEDGE :- Now lets take a pledge together:- We will stop the use of plastic bags and will use reusable cloth bags only. We pledge that we will educate our community people to save our environment. We will share the possible solution of Plastic Pollution with community people.
