Study Notes

Food Processing Cleaning & Sanitation

Learning Outcome: Apply principles and practices of cleaning and sanitation in food processing.
Cleaning Items: Detergents, sanitizers, detergent-sanitizers, procedures, clean-in-place (CIP), proper storage, pest control.

Importance of Cleaning & Sanitation

Hygiene: Crucial in food manufacturing processes.
Food Production: An integral part of food production.
Quality: Equipment ability to produce high-quality food depends on hygienic conditions.
Soiling/Fouling: Cleaning and sanitation intensity depends on the degree of soiling/fouling of equipment.
Contamination Sources: Dirty raw materials, foreign bodies, dirty production equipment.

Fouling

Definition: The unwanted deposit of material from a product stream onto a surface during processing.
Impact: Cleaning and sanitation influenced by fouling phenomena.

Cleaning & Sanitation Goals

Raw Materials (Fluid & Solid):
- Fluid: Screening, filtering (with/without aids), adsorption (e.g., activated carbon), and centrifugation.
- Solids: Settling, screening, sorting.
- Carryover dirt is not acceptable.
Foreign Bodies: Rely on mechanical separation.
Dirty Production Equipment: Scheduled daily cleaning to eliminate soil, pathogenic microorganisms, and/or detergents, and other disinfectants/antifouling treatment (e.g., passivation).

Goals of Cleaning and Sanitation (Passivation Process)

Raw Materials (Fluid & Solid): Fluid filtration, solids screening, and sorting. Carryover dirt removal is key.
Foreign Bodies: Removal via mechanical separation.
Dirty Production Equipment: Daily cleaning & sanitization is crucial to remove solid, pathogenic microorganisms, and soil.

Typical Components in Fouled Layers

Component	Solubility	Removal	Heat Alterations
Sugar	Water: Soluble	Easy	Caramelization
Fat	Water: Insoluble, Alkali: Poor, Acid: Poor	Difficult	Polymerization
Protein	Water: Poor, Alkali: Good, Acid: Medium	Difficult	Denaturation
Mineral Salts (Monovalent)	Water: Soluble, Acid: Soluble	Easy
Mineral Salts (Polyvalent)	Water: Insoluble, Acid: Soluble	Difficult	Precipitation

Cleaning & Sanitation Procedure

Procedure: Series of cleaning cycles with alternate compositions: Water > Detergent > Water > Sterilising chemicals > Water
Steps & Functions:
- Prerinse: Removal of loose soil and debris.
- Cleaning: Removal of residual soil using detergent.
- Interrinse: Removal of detergent residue and plant items.
- Sanitizing: Destruction of microorganisms (with/without heat).
- Postrinse: Removal of sterilizing chemicals with suitable bacteriological quality water.

Water

Surface Tension: High.
Functions: Solvent, transport medium, transmitter of thermal and chemical energy.

Detergents

Selection: Depends on the soil's composition (e.g., viscosity, solubility).
Types:
- Acids: Mineral deposits.
- Alkalines: Organic/protein-containing substances.
Conversion: Chemical conversion of deposits for removal from surfaces is crucial.

Cleaning Chemicals (Single Chemicals & Formulated Products)

Forms: Powder, liquid, or complex mixtures.
Mixed Products: Fully formulated products > Component products (basic substances + ingredient concentrates).
Categories: Acid cleaners, alkaline cleaners, enzyme cleaners, solvent-based.

Alkaline Cleaners

Reaction: React with vegetable/animal fats (saponification).
Effect: Degreasers, deep cleaners.
Dirt Removal: Strong/Weak alkalies, complexing agents, tensides, stabilisers, oxidisers, corrosion inhibitors, solubilisers.
Potential Issues: Irritant or caustic.

Acid Cleaners

Principle: Insoluble deposits > Water-soluble salts.
Soil Reaction: Chemically react with mineral/oxidized soiling.
Uses: Beer stone removal, milk stone, etc.
Potential Issues: Irritant, caustic, or toxic.

Enzymatic Cleaners

Uses: Protect industry materials and minimise cleaning chemicals.
Example: Savinase and Properase (proteases).

Sanitizers

Aims: Reduce living microorganisms.
Methods: Thermal deactivation and chemical sanitizing.
Types:
- Halogens (active chlorine compounds): Chlorine.
- Surface-active agents.
- Other components (e.g., peroxides, formaldehyde, ethylene oxide, monobrome acetic acid esters, ozone, labile germizides).

Cleaning Techniques/Procedures

Open Techniques: Suitable for external surfaces, large tanks, transport tanks. High labour involvement (COP, CHP, CLP, CFS). (A). Open techniques. (B). Closed techniques.
Closed Techniques (Cleaning-in-place (CIP) systems):
- Single use CIP systems.
- Multiuse/Reuse CIP systems.
Reuse CIP system: Cleaning/detergent solutions are reused.
- Automatic mode (pre-rinse, detergent recirculation, acid recirculation, sterilant recirculation, hot water sterilisation, final water rinse).

Proper Storage of Food & Chemical Agents

Food placement: Facilitate cleaning, maintain wholesomeness, and implement stock rotation (e.g., date codes).
Separate storage: Food, raw material, & chemical agents. Use safety symbols, ventilated, spill containment. Maintain secure storage in original containers, PPE.

Pest Control

Pests: No pests in food plants (affects product, leads to possible recall).
Control Measures:
- Habitat Elimination.
- Exclusion (eliminate access to food, warmth, moisture).
- Sanitation (regular cleaning).
- Extermination (traps, baits).
Concerns: Insects, Rodents, Birds (disease-carrying microorganisms).
