Materials use in Food Packaging Package style and construction play a big role in decisive the period of a foodstuff. The correct choice of packaging materials and technologies maintains product quality and freshness throughout distribution and storage. Materials that have historically been employed in food packaging embrace glass, metals (aluminum, foils, and laminates, tinplate, and tin‐free steel), paper and paperboard, and plastics. Moreover, a wider form of plastics are introduced in each rigid and versatile forms. Today's food packages usually mix many materials to take advantage of every material's useful, or aesthetic properties. As analysis to boost food packaging continues, advances within the field could have an affect on the environmental impact of packaging. The U.S. Food and Drug Administration (FDA) regulates packaging materials underneath section 409 of the federal Food, Drug, and Cosmetic Act. The first technique of regulation is through the food contact notifi...

Roles of Food Packaging The principal roles of food packaging are to shield food merchandise from outside influences and injury, to contain the food, and to produce shoppers with ingredient and organic process info (Coles 2003). Traceability, convenience, and tamper indication are secondary functions of accelerating importance. The goal of food packaging is to contain food in an exceedingly in an exceedingly that satisfies trade necessities and shopper needs, maintains food safety, and minimizes environmental impact. Protection/preservation Food packaging will retard product deterioration, retain the useful effects of process, extend shelf‐life, and maintain or increase the standard and safety of food. In doing thus, packaging provides protection from three major categories of external influences: chemical, biological, and physical. Chemical protection minimizes integrative changes triggered by environmental influences like exposure to gases (typically oxygen), wet (gain or loss), or l...

PRINCIPLES OF FOOD PRESERVATION The basic principle of food preservation are as follows: Preservation or delay of microbial decomposition: That is archived by : Keeping out microorganisms (asepsis) Removal of microorganisms,i.e., by filtration Hindering the growth of activity of microorganisms,i.e., by low temperature, drying, anaerobic conditions, & Killing the microorganisms,i.e., by heat or radiations. Preservation or delay by self – decomposition of food. This is brought about by : Destruction or inactivation of food enzymes i.e, by blanching& Preservation or delay of chemical reactions i.e, preservation of oxidation by means of an antioxidant. Preservation of damage caused by insects, animals & mechanical causes. OBJECTIVES The main objectives of food processing on a home scale, institutional scale, or in the food industry are similar. They include – Removal of unwanted matter from food – unwanted matters may be inedible, indigestible or harmful to health, such as hus...

Three main types of cross-contamination: Food-to-food, Equipment-to-food, and People-to-food 1.  Food-to-food Adding contaminated foods to non-contaminated foods ends up in food-to-food cross-contamination. this permits harmful bacterium to unfold and populate. Raw, undercooked, or improperly washed food will harbor massive amounts of bacterium, like enterics, clostridium perfringens, Campylobacter, coccus aureus, E. coli, and Listeria monocytogenes — all of which may damage your health if consumed.Trusted supply Foods that cause the highest risk of microorganism contamination embrace leafy  greens, bean sprouts, leftover rice, unpasteurised milk, soft cheeses, and shop meats, furthermore as raw eggs, poultry, meat, and food. For example, adding unwashed, contaminated lettuce to a contemporary dish will contaminate the opposite ingredients. This was the case during a 2006 E. Coli eruption that affected seventy one Taco Bell customers. What’s a lot of, leftovers unbroken within...

What is cross-contamination? Bacterial cross-contamination is defined as the transfer of bacteria or other microorganisms from one substance to another . Other types of cross-contamination include the transfer of food allergens, chemicals, or toxins. Trusted Source Many people assume that  food borne illness  is mostly caused by eating at restaurants, but there are many ways in which cross-contamination can occur, including; Trusted So Trusted Source primary food production — from plants and animals on farms during harvest or slaughter secondary food production — including food processing and manufacturing transportation of food storage of food distribution of food — grocery stores, farmer’s markets, and more food preparation and serving — at home, restaurants, and other food service operations Given that there are many points at which cross-contamination can occur, it’s important to learn about the different types and how you can prevent it.
