OUTLINE
  • Introduction and general information
  • Types of dairy substitutes
  • Regulatory and scientifically complexity
  • Flow diagram
  • Substitutes
  • Protein replacement
  • Fat replacement
  • Other components
  • Process parameters
  • Texture
  • Flavour
  • Conclusion

Importance
  • Economic view
  • Cost, lower income groups
  • Nutritional view
  • Less fat, saturated fat, cholesterol, calorie
  • Special dietary management
  • Weight control, heart disease, lactose
    intolerance, milk allergens etc
  • Shelf life
  • Consistant quality, no seasonal variance

PUFA
SOYBEAN

CHEESE SUBSTITUTES
  • Filled Products
  • Skimmed milk butter fat vegetable oil
  • Skimmed milk vegetable oil
  • Cheese Analogs
  • Synthetic
  • Soya protein soya oil artificial flavour
  • Partial dairy
  • Casein soya oil artificial flavour
  • Dairy
  • Casein butter oil EMC

Conventional cheese manufacturing methods Matured

Processed cheese manufacturing methods Non-matured

Regulatory-Scientific Complexity
Foods for special dietary uses
Parenteral nutritionals
Infant formulae
Special dietary foods
Enriched fortified foods
Analogs
Processed foods
Commodity foods

Flow diagram
  • Fat is melted (70C)
  • Stabilizer added
  • Water is blended
  • Protein is slowly added
  • Salt, flavours, acids are added

fast stirring

Changing protein sources
  • Dairy
  • Casein
  • Replacing calcium caseinat by sodium caseinat
  • Reconstituted calcium para casein(rennet casein)
    or lactic acid casein
  • Non-casein
  • Total milk protein
  • Milk protein concentrate
  • Non-dairy
  • Soy protein concentrate
  • Groundnut
  • Peanut etc

Dry rennet casein is adventageous due to its
stability and flavour.
  • 40 rennet casein TMP
  • Organoleptic
  • texture
  • higher pH
  • lower firmness
  • higher degree of fat emulsification
  • higher degree of casein dissociation
  • rennet casein MPC, 85 protein
  • increase firmness and sliceability (resistance to
    cutting)
  • decrease meltability

Curd pore numbers Boiled soy proteingtnative soy
protein gt control curd
Limited successcoagulum is not hard enough for
hard cheese. Favourable in spread-like cheese
Partial replacement the more plant protein the
softer cheese.

Substituting Milk Protein
  • Using non-protein components instead of milk
    proteins
  • Partial replacement
  • Pregelatinised or modified high-amylose starch
  • Pre-gelatinised maize starch
  • Mixture of sodium caseinate, soy protein isolate
    and corn starch
  • Modified starches or soy isolates and gelatin

9
Substituting Milk Fat
  • Hydrogenated vegetable oil
  • Soybean fat
  • conferred hardness and adhesiveness to the cheese
    analogues, but decreased their cohesiveness and
    springiness
  • Peanut fat
  • stretchy characteristics like mozzarella cheese
  • Polyols, fatty acid polyesters, sugar, sugar
    alcohol, and polyglycerols

10
Food Grade Ingredients
  • Addition of dietary fibre, seasonings, flavouring
    agents, binding agents, edible gums and
    hydrocolloids or mixtures
  • Emulsification
  • Buttermilk powder (phospholipid content), mono-
    and diglycerides, phospholipids,
    polysorbates,sorbitan esters and polyoxol esters,
    non-fat dry milk, whey (protein), casein or
    caseinates
  • Textural properties
  • carregenan, gelatin, gums
  • Melting properties
  • pH
  • Nutritional enrichments

11
Processing Regime
  • By changing the proportions of
  • Caseinates
  • Acid
  • Stabiliser
  • Vegetable oil
  • By adjusting the processing parameters
  • Heating times, temperatures
  • Physical factors
  • Extrusion
  • Proteolytic
  • physicochemical
  • changes
  • during ageing
  • Streching and pizza
  • Blending speed
  • lower degree of fat emulsification
  • higher degree of casein dissociation.

12
Texture
  • Water content
  • plasticiser
  • more elastic and less easily fractured
  • Fat content
  • softer, less springy, more cohesive and adhesive
  • increase in springiness, hardness and crumbliness
  • Protein content
  • springiness is effected by adsorption of the
    protein onto the fat surface
  • pH range
  • Emulsifying agents
  • Melting ability
  • Salt-Acid
  • citric acid or sodium chloride caused a
    significant decrease in cohesiveness and
    springiness and an increase in firmness
  • Melting ability Ca/Na

13
Flavour
  • Suitable enzymes
  • Self limiting lipase
  • Microorganisms
  • Proteolytic micrococcus
  • Flavour culture
  • Allow ripening

14
Conclusion
  • Why is not dairy analogs widely used?
  • Quality
  • Psychology
  • Regulations
  • Future trends
