Noodle quality testing: a range of texture analysis methods for a wide variety of noodle types – Part 6

ASSESSMENT OF NOODLE PRODUCT PACKAGING

Not only are the texture and physical appearance of noodle products crucial for achieving aesthetic appeal and optimal functionality – other factors concerning their look and feel can dictate their popularity. 

The packaging of a product can have a profound influence over purchasing decisions. Catchy names and bright colours are part of the attraction but packaging that performs the essential preservation function and is easy to use is also a key persuasion.

Regardless of product density, several texture analysis examinations can aid manufacturers in producing the best packaging to suit the noodle product in question. Available in cartons and packs, it is essential that the correct packaging format is chosen in order for consumers to make complete and convenient use of their noodle products.

Measuring the Seal Strength of Packaging

Tensile grip test on packaging seal

A simple peel test of a section of packaging seal using Tensile Grips (left) can indicate the potential problems arising from packaging seals. Variation of weld control (the time that heat is applied), or cooling control settings (the time allowed for the weld to set prior to the opening of the sealing equipment), can be investigated using this test, to attempt to optimise seal strength of each packaging material in use.

The Universal Peel Rig (below right), attached to the TA.XTplus texture analyser, measures the force it takes to peel off the sealed lids of product containers. It incorporates a multi-position platform, allowing containers to be held flat, or at 45° and 90° angles. As such, manufacturers can more precisely simulate the action of consumers, or handlers, to accurately assess both ease of use and stability of packaging seals. 

Universal Peel Rig test on foil lid

An adjustable rubber strap encircles the 
container to hold it in place, while a peel clip connected to the arm of the TA.XTplus holds the lid. As the arm moves up, the force required to peel open the lid is recorded. 

The Exponent software measures force against distance/time (as shown in the adjacent graph), ensuring the efficacy of the peel back lid, and measuring the effort required to open it.

THE FUTURE FOR TEXTURE ANALYSIS OF NOODLES

A range of rheological tests capable of monitoring noodle quality before and after processing would be useful to the noodle industry. The application of these, or similar modified, tests as near-line QA procedures for indicators of potential quality problems at all stages of the production process is promising. Additional research is needed to assess the effects of the minor constituents of noodles and the effects of non-wheat ingredients for the development of speciality noodles. 

 Advances in processing technology and new ingredient opportunities require quantitative methods to assess the changes in final product quality and hence monitor and control process parameters. Once accepted, and perhaps adapted and standardised, these and other rheological methods will provide the manufacturer with the tools to help develop better raw materials and produce high-quality noodle products.

With the wide range of texture analysis fixtures that are designed for use in this sector, Stable Micro Systems has proven its ability to provide an innovative solution for the complex quality demands of the food industry. All Stable Micro Systems’ products can be custom-made according to individual specification or new bespoke solutions delivered according to customer requirements.
