Yeast Firmness

Specification

Texture testing a yeast block for firmnessA processor of yeast blocks was looking for a quantifiable, consistent way to measure and ultimately better control the texture of their product. Current methods involved simple visual inspections and very subjective human sensory evaluation. Yeast blocks are extremely susceptible to either drying out too quickly or retaining moisture and becoming clay-like if not handled and packaged in the proper manner. In addition, the company runs different formulations and therefore the texture will vary between formulations. Because of these factors, a consistent and repeatable method of measuring and therefore controlling the texture is essential.

 

 

Method

yeast block firmness graphBefore testing, samples were left in their wrapping to hold the sample together for testing. All testing was done using a TMS-Pro with a 4mm cylinder probe which ran at a speed of 50 mm/min and 15mm into the block. The graph to the right shows the probe entering the product (1st curve) and the probe exiting the product (curve under line). This negative force tells us how the product fractures, if at all, when probe is exiting. This indicates whether the product is dry and crumbly or moist and sticky.

 

 

Significance

Test method and system proved differences between blocks of different formulations Allows for more concise control of textural attributes of the product Reduces the possibility of downtime due to a product that does not meet quality standard.

I have found FTC to be an excellent partner for our company. In particular, it has been especially gratifying to work with Shirl Lakeway. Both creative and accommodating, he worked very hard with us to develop our projects.

I appreciate his commitment to our joint efforts and his open-minded approach. He and FTC have been exceptionally helpful.

Nestle purchased a texture system from Food Technology Corporation in 2006. Since then I have recommended the texture system to several vendors in North and Central America. Staff at FTC was able to develop a simple training manual and procedure for the texture system allowing easy training in short period of time.

From purchasing of equipment through to installation and start-up, the level of personal care and service was remarkable. Shirl Lakeway and his staff at Food Technology Corporation are patient and understanding, and are always at our disposal for any assistance. Since we bought the equipment we have had no problems and feel very secure knowing that we can count on FTC for their support and service.

At the University of Saskatchewan, we are the proud owners of three generations of Food Technology Corporation texture equipment, all of which are still in working condition.

We are looking forward to future innovations from FTC.
