Color measurement of snack food

Snacks are very varied, including potato potato chips, crisps, roasted nuts, crackers, pretzel sticks and sweets. They offer flavors that can be sweet, sour, bitter, salty, savory, metallic and spicy. And the visual properties of snacks are just as different as their taste.

The surface of the samples is usually uneven, sometimes speckled with salt or spices and can rarely be measured at specific points. The measurement techniques vary depending on the type of snack, which usually includes coarse-grained, inhomogeneous and irregularly shaped food products.

Our solutions for snack food:

Aeros

Laboratory device for measuring color and degree of browning

  • Non-contact measurement

    The sensor detects the sample without contact, without having to measure through plastic or glass.
  • Large surface area

    The rotating sample plate captures over 170 cm2 of the sample in 35 measurements in 7 seconds.
  • Integrated QC software

    The EasyMatch QC Essentials quality control software is integrated into the device and provides all the required color indices and metrics.
Aeros
Aeros Application
  • Intelligent height adjustment

    The distance sensor automatically compensates for height differences in irregular samples.
  • Smart user interface

    Your measurement results can be easily transferred to existing LIMS or SPC systems.
  • Uncomplicated & precise

    Simple "one touch" measurement reduces training time, optimizes the workflow and increases your productivity.

SpectraTrend HT

On-Line/ In-Line color measurement

  • Contactless

    The sensor detects the sample directly on the surface, without contact, perfect for products of different heights.
  • Versatile

    The SpectraTrend is able to measure the color of granules, slabs, baked goods, fiber cement and much more.
  • Software evaluation

    Evaluation and process control can be carried out in the appropriate colorWorkbench software.
SpectraTrend HT
  • Precise sensor

    Monitoring with 5 measurements per second for color and height fluctuations.
  • Connectivity

    Measurement results are easily transferred to a PC, network and/or PLC and further processed in QA software.
  • Resistant

    Robust industrial design in NEMA4/IP66 approved housing with optional stainless steel housing for use in the food industry.

Application example:

Measuring the color of nuts

For snack food, it is important to ensure that the instrument has a large observation area, as this allows the sample to be easily placed under the sensor in different sized sample plates or in a Petri dish.Using nuts as an example, the samples are handled like bulk goods and removed from the batch in large sample trays, then placed under the sensor of the Aeros and measured. Make sure that the bottom of the plate is always completely covered. The measuring head of the Aeros can be adjusted horizontally and thus positioned eccentrically above the edge of a sample pan or the sample plate. For the measurement, the dish/plate rotates under the sensor while the device performs 35 measurements...

Color measurement of contact lenses

Color measurement of contact lenses

Color measurement is essential in the development of contact lenses in order to optimize both coloration and light transmission. Clear lenses are lightly tinted to facilitate handling without impairing the visual experience. Using specific color measurements, the transmission of light through the lenses can be precisely analyzed and controlled depending on the material. For tinted lenses, the precise measurement makes it possible to change eye colors authentically. HunterLabs Vista spectrophotom...
