Back 3

discovered microorganisms cause food to spoil not air

Front 4

Koch

Back 4

'Germ Theory'

Take colonies from disease animal and inject them in a healthy animal, that animal gets sick

Front 5

Bacteria: how does it reproduce

Back 5

reproduce by binary fission

Front 6

Yeast how does it reproduce

Back 6

Reproduce by budding

Front 7

Mold: how does it reproduce

Back 7

reproduce w/airborne spores produces filaments

Front 8

Viruses

Back 8

do not grow in food spoilage organism

Front 9

FAT-TOM

Back 9

Food, Acid, Temp-Time, Oxygen, moisture

bacteria likes protien, yeast needs sugar, mold; anything

Front 10

Pathogen

Back 10

something that gets you sick

Front 11

Acids

Back 11

pathogens wont grow under ph 4.6 (high acid)

Front 12

withstand heat treatment

Front 14

mesophile

Back 14

likes room temp to body temp

Front 15

psycophile

Back 15

prefers low temps

Front 16

psychrotroph

Back 16

will grow at low temps but prefers room

Front 17

aerobic

Back 17

grows with oxygen

Front 18

anaerobic

Back 18

only grows without oxygen

Front 19

facultative anaerobiic

Back 19

can grow in either anaerobic or aerobic

Front 20

water activity

Back 20

availability of water

Front 21

two ways we can get rid of water

Back 21

1) dry it

2) salt or sugar it (traps water in)

Front 22

Inhibitory substances

Back 22

helps with spoilage

Front 23

how do they respond to diverse condition

Back 23

death, dormancy, endospore (these are super hard to kill)

Front 24

Inhibitory substances happen by

Back 24

Naturally, benzoates, fermitatin, alcholol, propionate

Front 25

Food Born intoxication

Back 25

produces illness in food/toxin in food

Front 26

Staphyloccus

Back 26

human source

low body temp

cooking doesnt destroy toxin

Front 27

Back 27

heat labile neurotoxin

endospore former

causes paralysis and respitory failure
