Let’s begin defining…
To ensure that products meet the highest quality and safety standards with a systemic approach based on processes and a continuous improvement cycle, quality testing for chocolate manufacturing encompasses a broad spectrum of analyses and assessments to ensure that the final product is safe for consumption, consistent in taste and texture, and adheres to established industry and company standards.
The delightful world of chocolate relies on meticulous quality control at every production stage. From bars to truffles, maintaining customer satisfaction and upholding brand reputation hinges on rigorous quality processes.
Some of the major challenges or issues in quality control for chocolate manufacturing include:
| Some of the criteria analyzed in the process control may include: A. Physical and Sensory Analysis B. Chemical Analysis C.Microbiological Testing D. Allergen Testing E. Shelf Life Testing F.Ingredient Authentication G.Tempering Quality |
The latest version (Version 6), released in April 2023, includes strict requirements for labeling, allergen management, environmental monitoring, and more.
These updates integrate the requirements of ISO 22003-1:2022, strengthen requirements to help organizations meet the UN Sustainable Development Goals (SDGs), and incorporate feedback from a development survey.
New Requirements in FSSC 22000 Version 6:
| ✅ Luker Chocolate is FSSC 22000 certified, a testament to our commitment to food safety. The FSSC 22000 certification, based on ISO 22000 and ISO/TS 22002 specifications, is applicable to all food products and ingredients, ensuring safety across the entire production process. |
Allergen control is a critical aspect of our food safety program. The FDA and EFSA recognize a range of allergens that must be carefully managed to prevent cross-contamination and ensure consumer safety.
At Luker Chocolate, we manage allergens like milk and soy through rigorous controls, including deep cleaning protocols and comprehensive allergen testing. Proper labeling, such as 'Dairy Free' and 'Soy Free' claims, ensures that consumers can make informed decisions and trust the safety of your products.
Luker's allergen management program includes:
From inception, this approach involves pinpointing allergenic raw materials, meticulously handling their transport, storage, and every stage of the manufacturing process. Suppliers are requested to declare allergens within raw materials, with the onus on them to communicate any changes that could affect allergen presence. This ensures a proactive handling of allergen risks.
In addition to controlling allergens, we prioritize monitoring heavy metals like cadmium and lead in our products. These metals occur naturally in soil and plants and can become chocolate. However, we are committed to adhering to strict specifications.
Our laboratory employs atomic absorption spectroscopy to quantify cadmium and lead. A comprehensive sampling plan is enacted, from sourcing to production, ensuring meticulous adherence to specified cadmium levels. This plan includes monitoring at other production stages, such as milling, storage tanks, product formulations, and finished products.

Among the most important certifications is the FSSC 22000 (Food Safety System Certification), which ensures food safety throughout production.
We also have the BASC Control and Security Management certification, which ensures the promotion of safe trade in cooperation with governments and international organizations; the AEO certification (Authorised Economic Operator before the DIAN) for the export process; and the ISO 14001 certification in Environmental Management.
At the beginning of 2023, we obtained the accreditation NTC-ISO/IEC 17025:2017 for the Determination of Cadmium content and the Detection of Salmonella SPP in Cocoa and Chocolate products by ONAC (National Accreditation Organisation of Colombia), demonstrating that our products have the quality and safety expected according to the requirements of international markets.
Quality control services are essential for chocolate businesses, whether they produce or manufacture products for others. This validation is crucial to maintaining consumer trust and proves the product's quality.
Chocolate production is exposed to various physical, chemical, and microbiological hazards that must be controlled and monitored. Among the main ones is product contamination by heavy metals, pesticides, bacteria, and mycotoxins.
Addressing these risks, the chocolate industry strives to ensure quality and consumer safety by implementing preventive and mitigation measures in its processes through a Quality Management System with clear guidelines and principles to manage and improve the quality of products within each company.
| 🔎Streamlined Quality Management: Our integrated system merges all standards and policies into one user-friendly handbook aligned with ISO 17025. We ensure efficient and unified processes by covering infrastructure, equipment, staff competencies, complaints, grievance procedures, and purchasing. An in-house laboratory to guarantee the results' competence, confidentiality, and reliability. In addition, control plans, including aptitude tests, are carried out with international laboratories to support the results' reliability. |
"Taking into account the technical data sheets, we carry out attribute analyses, i.e., those physical characteristics of both the product and the packaging. We carry out routine studies related to physical-chemical tests, analysis of fats, granulometry, viscosities, and special analyses according to need. All batches have a sensory analysis that certifies that they are homologated and comply with a specific profile. This way, we finally have all the necessary elements to bring them to the market" explains Ostos.
Ensuring the quality of chocolate is a multi-faceted endeavor, considering both physical aspects and flavour profiles. For instance, during the physical evaluation of the beans, moisture is checked, cutting tests are carried out, and both external and internal mold is detected.
It should be noted that quality control allows the identification and correction of any deviations or problems in the whole production process, avoiding the distribution of defective or inconsistent products, which could damage the company's reputation. This also strengthens the relationship between the consumer and the brand.
Quality in Chocolate Production Begins at Origin:
From the moment the cocoa bean is harvested until the final product goes to market, each stage of the chocolate production process is carefully monitored and subjected to strict quality controls.
| “Maximizing quality in the cocoa value chain requires seamless integration and transparent relationships among growers, providers, and employees. Coordinating all process steps from planting to packaging fosters better quality control, sharing of best practices, and innovative feedback.” Sandra Ostos |
According to Luker Chocolate's Director of Quality Management, at the plant, various preliminaries involve compliance with good practices such as staff competence, hygienic habits, adequate infrastructure and equipment.
In addition, there is planning and delivery of materials for production, following protocols set out in the manufacturing routes. These routes establish detailed step-by-step operations, product recipes, and all necessary specifications, assuring that our products meet the highest standards.
A commitment to sensory profile harmony:
The art of sensory profiling is a meticulous endeavor. Our seasoned sensory professionals and trained panelists embark on a sensory journey grounded in theoretical and practical expertise. Through calibrated palates, our panelists master identifying basic flavours, detecting defects, and ensuring harmonized monthly assessments for consistency – a process aptly known as panelist calibration.
An interplay between skilled panelists and calibrated equipment, including internal teams and even those from our plant, underpins our rigorous approach. From cacao liquor profiles to identifying nuances and residues, our panelists' discerning reports guide strategic decisions.
| Did you know?💭 Luker Chocolate's pathogen monitoring program focuses on identifying, preventing, and controlling the insidious risks of pathogenic microorganisms. This ensures zero tolerance for cross-contamination from Salmonella, which has been identified as the primary pathogen associated with cocoa and its derivatives. Spanning four distinct zones within our facility, from direct-contact sites to areas removed from manufacturing processing, this approach serves as a robust initial defense. Our vigilant quality department holds products until microbiological results align with compliance standards, ensuring a secure release. If necessary, recall procedures are promptly activated. |
By steadfastly adhering to these stringent sensory evaluation protocols, from panelist calibration to prototype analysis, we achieve a harmonious sensory profile and maintain it across our entire range. This dedication to consistency encapsulates our mission to provide an experience that delights the senses with every indulgent bite.
