Abstract
In the last decade, bread consumption was decreasing in Hungary (from 44.5 kg to 34.4 kg/capita). Our aim is to identify the factors influencing the consumption of different bread and bakery products, using the Food Choice Questionnaire (FCQ).
FCQ is frequently used to explore factors (e.g., price, packaging, etc.) influencing the purchase of different food products. The adapted version of the FCQ for breads and bakery products is not yet available in Hungarian language. Word association (WA) and triangulation methods are usually used in the adaptation process.
Due to COVID-19, WA method was performed with a newly developed application presenting six photos of breads. This was completed by 193 participants. Responses were analysed using a categorizing triangulation technique, based on which the FCQ was modified.
In this study, we present the implementation and the results of the digitalized WA method and its use in the adaptation process of the FCQ.
Abstract
The soaking step of dry pulse products' – e.g. chickpeas' – food processing is a time consuming process. Soaking time can be significantly reduced by ultrasonic treatment or using higher processing temperatures. The effect of ultrasonic treatment can be investigated by examining the soaking water characteristics. Ultrasound-assisted soaking of chickpeas was performed at 25, 35 and 45 °C, respectively. Additionally, control samples were also prepared without ultrasonic treatment at the same temperatures. The dynamics of the fitted curve clearly shows the relationship namely the higher the treatment temperature, the faster the hydration of the raw material for both untreated and treated groups. In contrast to control group, swelling rate of 2.00 – except the group 45 °C – is not achieved during ultrasound-assisted soaking. In case of treated group, the swelling rate was about 1.90 for all temperatures applied. The ANOVA test shows that the color of the ultrasonically treated samples was significantly different compared to the control (F (5;12) = 207.86; P < 0.001). Average dry matter content and °Brix value were significantly higher in the ultrasound treated group compared to the control in case of all temperatures. This may indicate the destructive effect of ultrasound, which may cause more components to dissolve out of the raw material by the end of the soaking process.
