2. Food Storage
11
Preservatives addition Preservation in brine Preservation in acid Boiling and canning Refrigerator storage Freezer storage Dry storage 2.1 Food nature Some examples regarding way of food preservation/storage:
12
2.1.1 Relation between food nature and initial level and type of micro organisms By the term danger: we refer to the development of micro organisms in food or the appearance of chemical substances or foreign bodies in them, so that they are not suitable for eating Hard risk food Medium risk food Low risk foods Rarely responsible for food poisoning Can easily be affected by virus and pathogenic bacteria May be infected by pathogenic microbes and fungus
13
2.1.2 Perishable food Foods prepared and instantly consumed Cooked products that include fish, eggs, meat, cheese, cereal, poultry Prepared food which need an additional preparation phase before eating Smoked or salted meat or fish Dairy deserts Soft cheese Prepared vegetable salads and fruit salads Hard risk food These foods include:
14
Control of the transportation, storage and exposure temperature Use of suitable premises and equipment Training and personal hygiene of the staff Quick transportation, so that they are not left unrefrigerated Non exposure of an unpacked food Correct handling Correct procedures of waste disposal Cleaning Insect control Great attention to the expiration dates Recycling Measures that should be taken to ensure the suitability of the high risk food are:
15
2.1.3 Non - perishable food Medium risk food Low risk food These foods include: Hard cheese, Clod cheese, Cream cakes, Soft not yet ripened cheese, Fruit pies, Pieces of salted meat, Raw meat and raw fish, Delicatessen, Fresh milk, Fresh vegetable, Fresh fruit
16
2.2 Food storage methods / Equipments Types: Dry storage Refrigarator storage Freezer storage
17
Purposes: 2.2.1 Food packing material - Easy transportation - Security during transportation - Protection from super infection - Prevention of decay Materials: stainless steel, aluminium, tin copper, glass, plastic or multilayered, paper or carton in case of non-perishable food
18
Tempeture 2.2.2 Environmental parameters Humidity Atmosfere composition Foods danger from: Activity of the micro organisms, Chemical changes, Ferment changes Parameters
19
3 Food Preparation, Cooking and Service
20
3.1.2 Safe food handling and manufacturing practises Staff working in food preparation must wear smock, cap and maybe one-use only gloves, if it produces cold plates Staff working in service must wear clean clothes or a uniform Staff working in transports or storage must wear smock or a uniform Staff handling food is not allowed to wear big jewellery. Wedding rings, earrings and watches must be removed during working hours
21
Food preparation equipment and food contact surfaces 3.1 Food preparation, cooking and service and the prevention of cross contamination Safe food handling and manufacturing practises Temperature control in food preparation, cooking and service
22
Blue for cooked food Red for raw meat Yellow for raw poultry White for raw fish Green for raw vegetable 3.1.1 Food preparation equipment and food contact surfaces Colors for cutting surface: It is not allowed to use wood and electroplated metals as food cutting surfaces material. Hard Teflon is usually used Attention
23
3.2 Temperature control in food preparation cooking and service Raw product transport Storage Food preparation and cooking Storage or transport of cooked food Service
24
Some thermal treatments to attend: Relation between time, food temperature and micro organisms presence Thaw food (preparation) Safe internal temperature (cooking) Hot and cold holding Cooling and reheating foods
