1. Source of high-quality raw materials

The best fragrance factories will use high-quality raw materials and will conduct strict screening and inspection.

2. Strict raw material screening

Perfect raw material inspection process: The appearance, aroma, purity, and active ingredient content of the fragrance must be inspected.

Raw material traceability system: Clearly indicate the source, origin, and picking time of the essential oil on the product.

3. Advanced production technology

The best fragrance factories often master advanced essential oil extraction technology.

Distillation method

Principle: Separate the fragrance based on the difference in boiling points of different components.

Operation process: distillation in water, distillation on water, and steam distillation.

Advantages: This is a traditional and mature method. The extracted fragrance has a high purity and the product is relatively safe and natural.

2. Cold pressing method

Principle: Use physical pressure to squeeze out the fragrance ingredients.

Operation process: After cleaning the citrus peel, use a mechanical pressing device to squeeze it to break the essential oil capsules in it. Then, the purity of the flavor is improved by filtering and centrifugal separation.

Advantages: There is no heating step, the heat-sensitive components in the essential oil are retained, and the essential oil produced is of high quality, relatively safe and environmentally friendly.

3. Supercritical fluid extraction method

Principle: In a supercritical state, the fluid is used as an extractant to extract the flavor.

Advantages: Carried out at a low temperature, this method retains most of the heat-sensitive components of the flavor ingredients, is safe and pollution-free, and does not leave any harmful solvent residues.

4. Modern production equipment

The best flavor manufacturing plants are equipped with high-precision and high-efficiency production equipment that can achieve rapid and large-scale production.

Distillation equipment: simple distillation unit, continuous distillation tower

Pressing equipment: hydraulic press, screw press.

Separation equipment: separatory funnel, centrifuge

Filtering equipment: filter paper, filter cloth, filter screen and various precision filters.

Filling equipment: piston filler, peristaltic pump filler.

5. Production environment control

The best flavor factories have production workshops that meet international standards, such as 100,000-level GMPC workshops.

6. Perfect quality system

The best flavor factories will implement strict quality management systems, such as ISO 9001 and ISO 22000 international standard certification.

ISO 9001 quality management system standard: evaluate the factory’s quality management level from the perspectives of quality goals, leadership, planning, support, operation, performance evaluation, and improvement.

ISO 22000 food safety management system standard: If it is a food-grade flavor, it needs to pass this system standard.

It evaluates the factory’s quality management level by improving the foundation of the food safety management system, management responsibilities, resource management, hazard analysis and prevention measures, identification and control of critical control points, management of prerequisite programs (PRPs), monitoring and measurement, and improvement capabilities.

7. Professional testing team and equipment

Gas chromatograph-mass spectrometer (GC-MS)

Instrument composition: sampling system, gas chromatograph, mass spectrometer, vacuum system, data processing system.

Main features: strong separation ability, high identification ability, wide range of applications.

Application example: At Ghilawd Flavor Company, it is used to analyze the volatile components in flavors.

High Performance Liquid Chromatograph (HPLC)

Instrument composition: high pressure infusion system, injection system, separation system, detection system, data processing system.

Main features: high separation efficiency and fast analysis speed.

8. Strict finished product inspection

Ghilawd will conduct strict inspections on each batch of flavors to ensure that all indicators meet the quality standards, and the products are safe and reliable in quality.

1. Sensory inspection

Aroma evaluation, color inspection, appearance inspection.

2. Physical and chemical property inspection

Relative density determination, refractive index determination, optical rotation determination, acid value and ester value determination.

3. Component analysis

Gas chromatography-mass spectrometry (GC-MS) analysis, high performance liquid chromatography (HPLC) analysis (applicable to non-volatile components).

4. Stability test

Thermal stability test, light stability test, long-term stability test.

5. Microbiological test

Microbial limit test, pathogen detection.

9. Professional R&D team

A good fragrance factory will have some professionals like chemical engineers, perfumers, and botanists who can innovate and develop products.

GHILAWD has overseas professional perfume consultants, 5 senior perfumers, and 8 application and quality engineers. It is a very excellent creative team.

10. Scientific management system

A good fragrance factory will establish a scientific and efficient production management, quality management, supply chain management and human resources management system.
