Lasagna Stickiness Testing

With lasagna being a hugely popular dish both as supermarket ready meals and in industrial meals for pubs and cafes, the texture of the final product is extremely important. The stickiness is related to the starch content of the pasta sheet, which in turn is related to the cooking temperature and time. Measuring pasta stickiness with the TA1 texture analyzer from Lloyd Instruments allows these parameters to be optimized.
