Study Notes
Milk Biochemistry
- Milk is the primary substance for dairy products.
- Milk quality and safety are highly influenced by milk characteristics (fat, protein, salts, lactose, enzymes).
- Milk is a fluid secreted by female mammals to nourish offspring.
- Humans have domesticated mammals (cows, goats, sheep, buffalo) for milk production for millennia.
- Milk is a major global food industry.
- Lactose intolerance is a problem for many, particularly in Asia.
- A genetic mutation allows most Europeans to tolerate milk.
- Milk tolerance in Saudi populations shows a recent adaptation.
Introduction
- Milk composition varies, influenced by factors like diet and lactation.
- Milk is a complex physicochemical system.
- Milk composition is readily unstable.
- Milk's scientific mechanisms of production were not understood initially, before understanding dairy products.
- Understanding the secretion, composition, and influencing factors is crucial for processors and farmers.
Milk Composition and Constituents
- Milk is a complex mixture of various constituents in different phases.
- Main constituents are salts, lactose, and emulsified fat globules in a protein matrix.
- Casein (milk proteins) exists in colloidal aggregates.
- Milk proteins are classified into two groups based on their solubility.
Lactose
- Lactose is the dominant sugar in milk, composed of linked glucose and galactose.
- It's a disaccharide.
- Lactose influences milk yield due to its bacterial fermentation properties.
- Milk's pH drops due to lactose fermentation, leading to coagulation.
Milk Fat
- Milk fat is mainly triglycerides, esterified glycerol and fatty acid molecules.
- Milk fat globules (MFGM) have a protective coating to prevent degradation and maintain stability
- Fat globules vary in size.
- Milk fat quality is related to nutritional values.
- Milk fat quality impacts its technological applications.
Milk Proteins
- Milk contains casein, the main constituent with four caseins (as1-, as2-, β-, and к-caseins).
- Casein forms micelles.
- Whey proteins and their interaction with heat.
- Milk contains different proteins that have differing characteristics.
- Caseins are primarily responsible for the coagulation of milk, forming a matrix for dairy products.
Milk Salts
- Milk contains various minerals, primarily K+, Na+, Ca2+, Mg2+, Cl-.
- Salts are associated with casein micelles and serum phase.
- Milk salts influence the freezing point.
- Milk salts balance maintains osmotic pressure.
Indigenous Enzymes
- Milk from all mammals naturally contains multiple enzymes, essential for milk quality.
- The primary enzymes are alkaline phosphatase, plasmin, and somatic cell enzymes.
- These enzymes' activities can be affected by production treatments.
Factors Affecting Milk Composition and Processing
- Stage of lactation influences milk composition.
- Colostrum has nutrients, different to normal milk.
- Seasonal variations in feed, and calving times substantially affect milk output and composition.
- The diet of milk-producing animals significantly influences milk components.
- Factors such as mastitis, somatic cell count, and genetic make-up impact milk quality.
Mastitis and Somatic Cell Count
- Mastitis is mammary gland inflammation, typically bacterial.
- Mastitis increases somatic cell count (SCC) drastically in milk.
- Increased SCC alters the composition of milk, particularly protein profiles and enzymes.
- Subclinical mastitis poses difficulty in testing milk.
