Rice Firmness and Cook Profile

Application

texture evaluation of cooked riceThe texture of rice is very important to how the consumer perceives the quality of the product. Unfortunately, the texture is affected by several
different factors during the processing. The first thing that the producer has to determine is the quality of the incoming product. From this “starting point” adjustments in the processing can be made to produce a consistent product.

 

Problem

texture evaluation of cooked riceAs with most food products, controlling the texture rice takes constant manipulation of the processing controls to produce a product that is not only consistent, but also up to quality standards. Changes in the incoming raw ingredients are especially important with rice.

Different rice breeds along with variations in harvesting can greatly affect the protein and carbohydrate levels in product. These two characteristics have a great deal of influence on the final texture of the rice.

 

Solution

texture evaluation of cooked ricePrior to testing, raw rice was cooked using a standard method, drained, and then allowed to cool for a specific time. Rice was then spooned into the CS-2 Thin Blade Shear Cell until cell was full but not packed. The CS-2 cell is based on the design of Kramer Shear Cell. The difference is that it has more blades, closer together. This design is especially helpful when testing small particles like rice, as the pieces tend to fall through the regular shear cell.

All testing was done using the TM-2 Shear Press at a speed of approximately 90 mm/min. The peak force values from this test are an indication of the firmness of the product. This gives the processor valuable information about the product that they can relate back to things like proper cook time, soak time, etc.

 

Benefit

• Simple and quick test that gives the manufacturer an objective result that can be related to the quality of the incoming raw product

• Overall consistency and quality of the product can be improved

• Results will help to take the guess work out of adjustments to the process controls

Trusted by customers across the world

Our experience with FTC has been more than satisfactory, not only for the quality of the equipment you’ve got but for the post selling service that has proved to be excellent.

Any problem that we had, it took nothing more than a simple mail or phone call to have your immediate answer. We want to thank you very much for the quality of service provided.

The University of Arizona’s Nutritional Sciences Food Lab acquired a Texture Analyzer from Food Technologies about 5 years ago. The company has a great product, which is tailored to food needs. 

We have used the Texture Analyzer for both research projects and as a tool to demonstrate to students how food manufacturers can employ objective testing in product evaluation to show how differing ingredients in the same product can affect quality attributes. Its use adds another dimension to the foods labs.

Drew Lambert has been instrumental in helping with set up for testing and providing support whenever there’s a question. He has been a pleasure to work with and is always accommodating with our needs and schedules.  He has even sent us special attachments for special projects.  We couldn’t ask for a better technical support.  Thanks for a great product and great service.

As a seasonal vegetable processor, understanding crop maturity and the accuracy of this measurement is key to staying ahead of crop and knowing when to make the move from value to premium product as harvest time constraints permit.

The TU units provided by FTC give us the accuracy to work to much tighter tolerances, replacing older less accurate analogue equipment which in turn can affect final product grading and profitability.

The units are well designed, very low maintenance and are backed up with a strong support service which will allow them to provide many years of accurate, reliable service.
