Food DeteriorationPhysicalMoisture (food → air)Chemical O2 ‐Oxidative Rancidity (includes warmed‐over flavor)
O2‐Oxidative depigmentation (non‐enzymatic browning)
O2‐Myoglobin oxidation (Iron + O2 )
EnzymaticPolyphenoloxidase + O2 = enzymatic browning
Lipoxygenase + O2 = enzymatic oxidative rancidity
MicrobialO2 – strict aerobic spoilage preventedO2 – facultative spoilage slowed ~7X

CC‐SV bulk cooking and bulk cooling8 man hours prep + overnight cooking/cooling = 4000 ckn breasts
Compare grilling time, gas cost, man hours? x 4000 ckn breasts

COOKLOSS
Burger at $3 / lb = $2.25 in meat / $0.75 in cook lossCook 10,000 ‐ 1/3rd lb burgers per day → $2,500 cook loss per day (~$90,000 per year)
Cook Chill (in bag) Dirty RiceBag dry ingredients + cooked meat (vacuum seal)
Refrigerate or freeze
Open, add water, re‐seal
Cook and hold at 135°F
SV – higher temp longer timecollagen destruction 160‐180°F ; 24‐72 h
SHORT RIBS SKIRT STEAK ‐ Brisket
Collagen Gelatin
Confit Take a piece of fatty and sometimes tough meat or poultry like duck legs, pork belly, lamb shank, or brisket Vacuum package with herbs and spices Cook at 170‐180°F for several hours to convert all of the solid fat into liquid and break down proteins and collagen while retaining all of the moisture Cool and store until ready for service Remove from bag, crisp the skin and serve
