5 types of fermented dairy products
1. yogart
2. kefir
3. kumiss
4. buttermilk
5. acidophilus milk
Define fermented dairy product.
Milk to which single or multiple cultures of lactic bacteria and mold/yeast cultures added for flavour and aroma
2 classifications of cheeses.
unripened or ripened
3 categories of ripened or unripened.
soft, semi soft, hard
example of soft and unripened cheese.
cottage, cream
example of semi-soft and unripened cheese.
example of soft and ripened cheese.
brie, feta, camembert
example of semi-soft and ripened cheese.
blue, brick, limberger
example of hard and ripened cheese.
cheddar, swiss, edam
What 2 product are used to form lactic acid in lactic fermentation (yogart)
Lactose + Lactobacillus bulgaricus or Streptococcus thermophilus -----------------------> Lactic acid
Mixed fermentation. e.g. kefir
acids (streptococcus lactis, Lactobacillus bugaricus)


alcohols produce - tortula kefir
- tortula cremoris (yeast)
Lactic starter cultures
-chemical acidification will coagulate protiens but lacks flavour.
-starter enzymes metabolize lactose and citric acid to diacetyl and acetic acid
-limited amts of flora will not interfere significantly with flavour.
-Rapid cooling after pressing controls cheese flora.
-controlled breakdown of coagulated milk proteins
- cheese microflora and enzymes release flavour and aroma through proteolysis
- milk fat content and lactic starters contribute to flavour.
- control culture numbers to prevent bitterness
Cheddar cheese process (ripened)
1. Milk heated 30C and starter cultures added (strep lactis and strep durans)
2. Rennet added (quickens curd formation (30 mins)
3. Curd cut into small pieces
4. Mixture cooked at 38C (whey drained)
5. Salt added
6. Curd wrapped in cloth and pressed

7. 3 - 13 C for weeks to months (longer ripening is sharper taste)
Low fat cheese
lacks flavour and more elastic texture
-coliform bacteria added to curd.
-CO2 stretches the mass around the colonies of bacteria
-holes form in cheese body
processed cheese
mixture of a variety of cheeses

heat treated and homogenized

flattened by rolling cylinder, cut and wrapped
Mould ripened cheeses
Presence of mould within the cheese.

Penicillium roqueforti or surface mould, P. cammemberti
-lactic starters coagulate -proteins by acidification
-mould de-acidifies the cheese through hyphae enzyme secretions
-curd inoculated with mould
-curd pierced to allow air entrance and support aerobic growth
-blue-veined cheeses undergo intense proteolysis contributing to strong flavour.
-Alkaline nature of mould-ripened cheese allows acid sensitive bacterial grouwth which contribute to flavour
Curd contamination
-post-pasteurization contamination since milk is not makd in a strictly sterile environment.
-employee handling
-pH (5-5.2) not sufficient
-Aw to high
What is CCP in unripened cheese storage safety
4 ways that spoilage can occur
-off flavour and texture or microbial contamination is too high.
-inadequate acidification may allow acid sensitive bacteria to produce gases.
-gases affect flavour and texture.
-competition with starters will impair ripening flavour.
Spoilage during ripening
-undesired flora will impact on texture, flavour and appearance.
-gas holes controled
-putrification if insuffient acidity is produced.
-pigments may develop if water used contains metal salts.
Spoilage of finished cheese
-perishabiliy increases with Aw
-hard cheese such as swiss and cheddar are most stable
- moulds are a primary spoilage organism.
Ripened cheese safety
-lactobacilli by products are antimicribial and destroy pathogens during ripening e.g. peroxidase
- acidification reduction of Aw to < 0.9 and antibiotic nature of by-products makes properly reipened cheese shelf stable
What is the most perishable of all the meats?
What does rapid autolysis mean?
fast acting enzymes
Produces less/more acid than beef?
Why does it produce less acid than beef?
Carbohydrates break down into acids and there are less carbs in fish.
Less acid in fish means what to the inhibition of bacterial growth?
means less inhibition (lower glycolysis)
Why are unsaturated oils more susceptable to oxidative racidity?
Double and triple bonds are more susceptable to binding with other things
Crustaceans have limited shelf life because of
increase protein level
For mulusks the higher the acid level the ____ the quality of molusk.
More carbs means more ____ and more ____
gycolysis, acids
Why do fish stink
high amines that break down
large number of volatile N2 compounds are found in what foods?
fish, crustaceans, mollusks
For fish where are most of the bacteria found?
outer slime, gills, intestines
Why are bivalves more susceptable to contamination?
filter feeders and concentrate contaminants
Why eviscerate fish?
enhance quality
any food in intestine will spoil.

-do as soon as possible becasue enzymatic activity can break down stomach into flesh.
what does the flora in fish reflect about the environment?
reflects the microbial content of the water in which they live
What is the relationship b/w heavy fat content and rancidity?
Heavy fat content makes it more oxidative rancidity
How can you get an indicator of age of fish?

legal action

enteric bacteria
viruses, parasites
