How to reduce the color change of the food & candy products

On the Internet is filled with all sorts of rub off food news (and images).Perhaps because of packaging and printing errors, but if you open a piece of dark chocolate bars, only to find that it is...The grey?

Inconsistent color may be a major bottleneck in the process of food production.Consumers tend to call a spade a spade, and often share on social media platforms.And this, is just around the corner, like a snowball was infinite amplification, became the most terrible food companies a nightmare.

Although food and candy manufacturers often cannot stop unscrupulous sellers in its shelves selling old candy, but they can control the consistency of color during production, to ensure the consistency of product, and avoid unnecessary consumer panic caused by production mistake.

Color consistency to play a leading role

Choose appropriate color suppliers is very important

Turn the Bar blog postDiscusses not only related to the packaging and food manufacturing and food and candy related key ink properties.This paper points out that color standard is to ensure that the products match the target color a critical practice, because "is perfectThe onlyChoice."

Although has been our best, but the color change is still a problem.Therefore, clearly grasp the quality of ingredients and how best to achieve accurate color is essential.

Everything starts with the choice of suppliers.

For years, those who ignore the color consistency of the brand often find their product series by the Numbers, some of them have even been discarded by consumers.

Accurate color rendering of challenging, given the need to be in a variety of food surface (such as chocolate, peanut butter or licorice) implemented on accurately reproduce, and this process often hold different types of devices, different people use different techniques in various production environment.

Color change is inevitable, which can result in product defects, leading to consumers lose confidence in the brand.

Should, therefore, before mass production start even, will minimize the color change.Active brands by ensuring maximum consistency of raw materials, and at the beginning of the manufacturing cycle to set up standards to do this, to help quell the fluctuations in the whole process and finished goods.

The following two Suggestions are food and candy maker should vigorously implement (if they are not yet implemented), to ensure that the quality of the supplier.

• Using the detailed and correct risk assessment of raw materials and the supplier approval process to achieve consistency between batches

Effective supplier approval and management helps to keep the consistency between batches of raw materials, reduce the risk of color change between batches.

Review raw material supplier qualification is a must conditions, long-term records should include the qualified product quality.Check with an operations duration of audit results, customer evaluation, past, and - crucially -Strict adherence to all regulatory requirements associated with the industry standards and conditions.As Mr Nu-lax No - Tox team points out, we need to adhere to strict level of vendor selection and product choice, find the products suitable for the client application.

• Hire professional material review team to ensure quality

All materials the audit team shall be by product quality system of representatives of the three elements.Card nu-lax No - Tox blog postThe quality of the three stakeholders are described:

1. Regulatory affairsConfirm the material can be used in the application and the expected distribution market.The team must keep up with the current regional changing laws and regulations, standards and to ensure that all kinds of materials to meet the requirements.
2. Quality assurance (QA)Maintain compliance and supervise the process control.QA team confirmed the suppliers conform to the standard, provide supplier monitoring and supervision, and maintain a high level of supplier reliability.
3. Quality control department (QC)Must strictly control the product conform to the specifications, and ensure the consistency between batches.QC is responsible for ensuring that raw materials in accordance with customer requirements specifications.

To maintain consistent, high quality color technology

For decades, color pigments and using hard shake pot craft a famous candy, use of color contrast test to ensure that the quality has been the major means of designers and color suppliers.Unfortunately, the reproducibility is a long struggle.In the process of raw material selection, composition of color contrast test on final coloring products, helps manufacturers to set standards, create a copy of a commercial scale formula.

Color consistency is depend on the amount of color method.The quantity of the industry there are two key process:

• The Delta E Values

The Delta E measuring samples and color difference between the known quality standard.These measurements can let us group after group to create a more consistent colouring agent."Delta" is a mathematical terms, refers to the variable or function change, and the suffix "E" is refers to the German word empfindung, means "feel".As a result, the Delta E translated into the differences of "feeling".Using the Delta E value of laboratory equipment to stain to identify differences when compared with the known values.These differences can be improved before and during the manufacturing process, so as to create a more consistent and reliable products.

• L * a * b *

L * a * b * observed in more detail the consistency of color, but also a little hard to describe.We can imagine it as longitude, latitude, altitude, geographic coordinates, etc.In this case, the "L" refers to the brightness, "a" is the value of the red/green axis "b" is the value of the blue/yellow shaft.These values provide a way to find and describe color.L * a * b *能够进行严格的着色剂测量评估，也能够在制造过程中进行微调，从而使得着色剂产品符合最严格的颜色标准。

Quality control department using a range of tools and equipment to analyze these data, to ensure that products manufactured in accordance with customer specifications and expectations.With the progress of technology, industry management and accurate measuring of the capability of color also have improved, but also let customers and consumers more trust.Although the instruments and the development of professional technology greatly reduces the inconsistencies color used in food production, but manufacturers can still take some measures to keep the color consistency between batches.

"Color changing" is synonymous with the term "quality change - for any food or candy brand, this is a very bad way (literally)...And color and has a strong quality system expertise of experienced manufacturer cooperation, helps speed up the project progress, increase production, reduce the manufacturing cost and protect the brand reputation.
