Texture Analysis of Beverages

The word “beverage” does not conjure up images of Texture Analysis, which is best suited to samples with properties ranging from viscous liquids to solids. However, with raw ingredients and packaging to consider, beverage manufacturers have just as much need for Texture Analysers as any other industry.

With a worldwide drive to reduce plastic consumption, paper straws have made an appearance in many bars and restaurants. They are an excellent alternative and a blast from the past for some consumers, coming in a wider range of patterns than we are used to seeing on plastic straws. However, a drawback of paper straws is their lack of structural integrity once they have spent some time soaking in a drink. The softened end not only has an unpleasant mouthfeel; it also reduces the straw’s effectiveness. 

Texture Analysis of a Spa Day

A trip to a spa is a feast for the senses designed to be as indulgent and relaxing as possible. Scented candles, smooth creams and scrubs rid the guest of layers of tired skin and rejuvenate their spirits. 

It is not a surprise, then, that the texture of the products involved is of high importance to manufacturers looking to supply high end spas, and Stable Micro Systems have a testing solution for almost every circumstance.

Using Texture Analysis Data to Predict the Results of a Sensory Panel

The food industry is highly motivated to lower the cost of product development, and where possible, cheaper alternatives to traditional techniques are sought. 

For example, sensory panels are expensive but there is an alternative that can allow companies to lean away from this particular cost.

Sensory perception can be correlated with parameters measured using a Texture Analyser to simplify product development, investigating the mechanisms by which physical food properties act to produce specific sensations during consumption. Once appropriate equipment has been purchased, the measurement of physical parameters is often seen as an efficient alternative to costly sensory panels. Consequently, many studies in vastly different areas of the food industry have been performed with the aim of establishing methods that reflect in-mouth sensory properties using physical parameters.

Texture Analysis update in the Petfood World

The very best in nutrition for our animal friends. 

Four out of five pet owners consider their pet a member of the family and with 79% saying the quality of their pet’s food is as important as their own, it is not surprising that the premium sector accounts for 40% of the $26 billion US pet food market. 

Six recent interesting articles about Texture Analysis

Texture is a food product’s defining factor – getting it wrong can mean rejection by consumers. A product could taste great, have a healthy advantage, and look fantastic, but if the texture doesn’t hit the mark, it just won’t work. 

For those who are new to this field of science, the following recent articles give a good introduction in several explanatory styles and highlight the importance of food texture:

Is your Ice Cream Tub at the Top of the Stack?

An ice cream tub has an important job. It must attract the supermarket shopper with an appealing design, often showing off the ice cream through a transparent window. 

The structure of the ice cream should be protected – any decorations or surface construction should remain in place and not be squashed by the lid. At the same time, there are requirements for packaging to be lightweight, stackable and suitable for nesting in pallets during shipping as well as minimising both empty space and material usage.

Altering Data Acquisition Rate and Corner Frequency to Optimise your Texture Analysis

DATA ACQUISITION RATE 

Otherwise known as sampling frequency, the data acquisition rate of a test is defined by the number of data points collected per second (pps). In general, a higher data acquisition rate allows the collection of more detail during a test. The maximum possible data acquisition rate has increased over the years with improved technology and increased computer memory.

The recently released Connect range of Texture Analysers allows data collection up to 2000pps. This higher acquisition rate (2000pps) detects up to four times as many force changes per second as the previously available rate (500pps) and so it is very well-suited to applications involving high rate fracture, such as crispiness or high speed events such as in the measurement of adhesives or brittle samples. 

Why change from the Standard Method approach?

A Standard Test Method is a definitive procedure that produces a test result. In order to ensure accurate and relevant test results, a standard test method is explicit, unambiguous, and experimentally feasible, as well as effective and reproducible.

A standard test method can be considered an experiment that determines one or more characteristics of a given sample and the detail of the test method is usually as a result of creation from a number of experts in that measurement field. Within the materials testing industry, for example, there are an enormous number of standard methods (e.g. ASTM, ISO) that have been developed to measure specific sample characteristics.
