Olive Oil Production Course

Lesson 1 • Olive Oil Classification and Grades

Defines official grade categories from extra virgin to refined and lampante. Connects classification standards to quality benchmarks used throughout the course.

Lesson 2 • Industry Structure and Supply Chain

Maps the roles of growers, millers, packers, and distributors in the value chain. Orients students to the professional landscape they will operate within.

Lesson 3 • Chemical Composition Overview

Introduces fatty acid profiles, polyphenols, and minor compounds that define quality. Builds the chemical literacy needed for later sensory and analytical chapters.

Lesson 1 • Variety Selection and Characteristics

Examines major cultivars by oil yield, flavour profile, and regional adaptation. Variety choice directly determines oil quality potential and harvest strategy.

Lesson 2 • Olive Tree Biology and Growth Cycles

Covers tree anatomy, phenological stages, and annual growth patterns. Understanding biology underpins all orchard management decisions covered in this chapter.

Lesson 3 • Soil Management and Irrigation

Addresses soil preparation, nutrient management, and water-use efficiency techniques. Proper soil and water management directly elevates polyphenol content in fruit.

Lesson 4 • Pruning and Canopy Management

Teaches pruning objectives, timing, and techniques for light penetration and airflow. Effective canopy management reduces disease pressure and improves fruit uniformity.

Lesson 1 • Post-Harvest Fruit Handling

Addresses transport, storage temperature, and time-to-mill targets to prevent fermentation. Proper handling between field and mill preserves the quality gains achieved at harvest.

Lesson 2 • Maturity Indices and Ripeness Assessment

Introduces the maturity index, skin colour charts, and oil accumulation curves. Accurate ripeness assessment is the single most critical harvest decision.

Lesson 3 • Manual Harvesting Methods

Covers hand-picking, raking, and combing techniques suited to traditional and steep-terrain orchards. Manual methods preserve fruit integrity and minimise bruising.

Lesson 1 • Centrifugal Separation Systems

Details two-phase and three-phase horizontal decanter operation and vertical centrifuge polishing. Centrifuge settings directly determine oil clarity, yield, and water content.

Lesson 2 • Crushing and Malaxation

Explains hammer mill and disc crusher operation followed by malaxation parameters. Crushing style and malaxation time and temperature govern oil yield and phenolic retention.

Lesson 3 • Traditional Pressing Methods

Examines mat-and-press extraction as a historical and niche artisan technique. Understanding pressing provides context for comparing modern and traditional quality profiles.

Lesson 4 • Receiving and Cleaning at the Mill

Covers fruit reception, weighing, leaf removal, and washing procedures. Clean, leaf-free fruit prevents off-flavours and protects downstream equipment.

Lesson 1 • Polyphenol and Antioxidant Analysis

Introduces total polyphenol quantification and individual compound profiling by HPLC. Polyphenol data supports health claims, shelf-life prediction, and premium pricing.

Lesson 2 • Fatty Acid Profile and Authenticity

Uses gas chromatography to verify fatty acid composition and detect adulteration. Authenticity testing protects brand integrity and satisfies regulatory requirements.

Lesson 3 • Peroxide Value and Oxidation Status

Covers iodometric titration for peroxide value and its link to primary oxidation. Peroxide value combined with FFA gives a complete picture of oil freshness.

Lesson 4 • Spectrophotometric Indices

Explains K232 and K270 UV absorbance measurements and their regulatory limits. Spectrophotometric indices detect both primary and secondary oxidation compounds.

Lesson 1 • Sensory Science Fundamentals

Introduces olfactory and gustatory physiology relevant to olive oil evaluation. Understanding sensory biology explains why standardised conditions are mandatory for valid results.

Lesson 2 • Official Panel Test Protocol

Details the standardised glass, temperature, tasting sequence, and scoring sheet procedure. Strict protocol adherence ensures results are comparable across labs and panels.

Lesson 3 • Positive Attribute Recognition

Trains identification of fruity, bitter, and pungent attributes and their intensity scoring. Positive attributes are the defining markers of extra virgin quality.

Lesson 4 • Defect Identification and Classification

Covers musty, fusty, rancid, winey, and muddy defects with reference standards. Defect detection is the critical skill that separates virgin from extra virgin classification.

Lesson 1 • Packaging Materials and Formats

Compares dark glass, tin, PET, and bag-in-box containers for light and oxygen barrier performance. Packaging choice is the primary consumer-facing quality protection tool.

Lesson 2 • Filtration Before Packaging

Examines plate filtration, diatomaceous earth, and membrane filtration options. Filtration removes water and fine particles that accelerate fermentation and cloudiness.

Lesson 3 • Oxidation Mechanisms and Triggers

Explains autoxidation and photooxidation pathways and the role of light, heat, and oxygen. Understanding degradation chemistry is the foundation for all preservation decisions.

Lesson 4 • Shelf-Life Testing and Date Setting

Applies accelerated ageing tests and real-time monitoring to establish best-before dates. Accurate shelf-life claims protect consumers and reduce commercial liability.

Lesson 1 • Traceability and Fraud Prevention

Designs lot-tracking systems and authentication tools to prevent adulteration and mislabelling. Robust traceability protects brand reputation and satisfies regulatory audit requirements.

Lesson 2 • Food Safety Management Systems

Applies hazard analysis and critical control point principles to olive oil mill operations. A documented food safety system is mandatory for access to major retail and export markets.

Lesson 3 • Protected Designation Schemes

Explains geographical indication and protected designation certification processes and benefits. These schemes command price premiums and require strict production rule adherence.

Lesson 4 • International Quality Standards Overview

Surveys the major intergovernmental and trade-body standards governing olive oil grades globally. Knowing which standards apply to target markets is the starting point for compliance.
