Delivering chocolate perfection



Scientists involved in the long and complicated process of creating the ‘perfect piece of chocolate’ reveal that while ‘perfect’  may be used to lure customers to buy the perfect crème egg or enormous chocolate-stuffed Easter Egg, perfect chocolate is actually the result of a well-scrutinised global supply chain working at its best.

This insightful account comes from a company called Intertek and their task is to work closely with chocolate manufacturers, testing, inspecting and evaluating at every stage of production from bean to bar.

The average chunk of sweet confection undergoes hundreds of assessments from the day the cocoa seed is planted (tested for water, segregation, nutrition), to when the cocoa pod is harvested (assessed in terms of child labour, salary scales, fair trade). These checks also include how the chocolate is transported and manufactured (tests for manufactured pollutants, manufacturing systems assessed), to the way it is blended, packaged and sold.

Every aspect of the chocolate production process from ingredient to blend to the finished product is monitored, tested and checked against regulations to ensure it’s safe, of good quality and conforms to all the legal standards. Analysis ranges from labour pay scales and conditions of farm workers tending the cocoa pods, to environmental issues around rainforest use, to monitoring the transportation process, as well as quality and safety in the manufacturing, packaging, distribution and selling of the finished chocolate product.

At the Cocoa farm itself, the task of where to plant and how to nurture the crops, is in itself a challenge.   By using precision farming, soil labs such as Intertek’s South Africa labs, carefully determine and provide details on how to respond to the land’s needs.  Allowing the farmers to accurately pinpoint and apply the right amount of nutrients in the precise location at the right time. This not only benefits the crop’s yield but creates a sustainable environment for future crop cycles and supports the local community.

To achieve a premium product, the cocoa chocolate must be quality checked pre- and post-shipping. It must be monitored to ensure correct loading and checked again during transit to ensure it is kept apart from the bulk cargo. If it has to be held in storage overnight, a further stock monitoring service may be required.

The seal on the premium cocoa is broken at the factory prior to the manufacturing process and all papers are checked. The factory itself will be subject to testing to ISO standards in terms of hazards, safety and quality procedures and practices.

When blending with other ingredients, each of those ingredients will have been tested and certified. For example, the milk used for blending with the chocolate will have undergone its own rigorous testing process including checks on cattle welfare on the farm as well as safe milk collection.

The final product is tested for cocoa mass, butter fat and milk solids to ensure that the product complies with chocolate regulations around the world and that the final product will be labelled correctly.  Other testers have the enviable task of carrying out sensory tests to ensure the chocolate feels, tastes and looks right.
Equally Intertek experts are also called upon to eat chocolates and sweets to assess whether these might cause choking hazards. Computer modelling and other scientific and physical analysis are also used to support these findings.

With the growing prevalence of allergies, such as dairy soya, nuts and gluten, these are controlled by risk assessments and quality management with the system being verified by audits and testing to ensure unlabelled allergens are not present in the final product. Also the microbiological quality of the final chocolate product is assessed.

Another area under increasing scrutiny is packaging testing. The chocolate wrappers should be proofed as safe when coming into in contact with the delicious chocolate, providing no risk for human health.

The testing continues once the chocolate hits the shops, as audits are also run in the form of brand quality to ensure the product fits with the look and feel of the brand. Mystery Shopper audits are then conducted to ensure the level of customer service being offered is as pristine as the chocolate itself.

So this Easter, as excited adults and children comb gardens for eggs and tear open silver paper packaging in search of a mouthful of chocolate, it’s worth considering how many people have worked together along the global supply chain to turn that simple pod into that perfect piece of mouth-watering scrumptiousness!
