What’s the difference between ready to eat and ready to cook products
Ready to eat
- eaten as it is
- doesn’t need to be cooked
- no further preparation needed; safe for consumption
Ready to cook
- cannot be eaten as it is
- must be cooked
- must be cooked to specific temp to kill any microbes
What are some considerations when selecting packaging material
- shelf life expectancy
- cooking or storing instructions
- robust packaging to protect integrity of the food, be stored and transported effectively without damage
- can be cooked or heated in packaging
What are some characteristics of packaging
- moisture resistant
- doesn’t leach into product
- tolerant of heat
- strength to withstand force such as pressure of mechanical impact
- avoids air ingress/ escape
- elastic or flexible
What are some examples of food packaging
- plastic bags
- plastic pots
- aluminium foil
- paper
- cardboard
What are some sealing methods of packaging
- heat seal
- ultrasonic seal
- pressure
- adhesive
- folding/capping
Why is plastic frequently used for food packaging
Safety
- durable material
- shatterproof
Hygiene
- stops food contamination
- stop allergens form mixing or viruses transferring
Other
- Lightweight,
- easy and cost effective for transport
Recycling
- recyclable and biodegradable
Shelf life
- extend shelf life reducing cost to customers
- reduce food waste
Availability
- widely available
- keep up with demand
What are some issues that can arise from automated flat pack cardboard box erectors that would need engineering intervention
- moisture ingress
- size discrepancies
- poor finish
- misshapen cardboard
- poorly define folding points
- cardboard too rigid to form a shape
How can being environmentally help a reputation
Good reputation and being environmentally friendly can help win tenders/ new business
Metal composition: what two metals are added to iron to make stainless steel
Nickel and chromium
Metal composition: which metal is added to 316 stainless steel to make it resistant to corrosion
Molybdenum
Which common food/ substance is 316 more resistant to
Salt or salt water
What are some reasons as to why stainless steel is used as a work surface in good contact production
- non-porous
- doesn’t degrade
- can be welded
- acidic resistant
- resistant to heat distortion
- corrosion resistant
- easily cleaned
- impact resistant/ robust
