Dill (Anethum graveolens L.) is a popular herb used in many regions, including Baltic countries. Dill is widely used for flavoring foods and beverages due to its pleasant spicy aroma. The aim of this work was to determine the best blanching method for processing of dill prior to microwave vacuum drying based on sensory properties, color and volatile compounds in dried product. Two blanching med...

Watercress (Nasturtium officinale) colour changes due to blanching by heat and a combined treatment of heat/ultrasound (thermosonication) were studied in the temperature range of 82.5 to 92.5 °C. The application of thermosonication was intended to enable less severe blanching treatments and, therefore, improve the quality of the blanched product. The thermosonication blanching processes promote...

The use of ultrasound in food processing creates novel and interesting methodologies, which are often complementary to classical techniques. In this work, the effect of heat and the combined treatment heat/ultrasound (thermosonication) on the thermal degradation kinetics of vitamin C in watercress (Nasturtium officinale) was studied in the temperature range of 82.5 to 92.5 °C. First order react...

Many workers using vibratory tools suffer from handarm vibration syndrome. Among symptoms of the syndrome, blanching attack is the most typical. In terms of medico-legal aspects, objective recognition of Raynaud’s phenomenon is considered to be most important in judging the syndrome as an occupational disease. Measurement of finger systolic blood pressure test (FSBP%) in the laboratory has rece...

high nutritional value and existence of bioactive components in sesame seeds converted it to a valuable food. one of the methods to increase per capita consumption is processing of sesame with different ways such as production of sesame milk. in this study, the effect of blanching time (0 as a control sample, 15 and 30 min) at 95°c and roasting temperature (0 as a control sample and 145°c) for ...

Investigations were carried out to study the effects of selected blanching treatments on the quality of carrots over a temperature range of 80–100C. The blanching treatments selected were steam, water, 0.05 N acetic acid solution and 0.2% calcium chloride solution. These blanching treatments were evaluated with respect to the inactivation time of peroxidase (POD) and catalase, and the process w...

The sites of 92 rheumatoid nailfold lesions were compared with sites of pressure as indicated by tissue blanching during gripping. A close correspondence between sites of blanching and sites of vasculitis was found, and this is discussed in relation to the possible role of vascular compression and blood stasis in the development of rheumatoid vasculitis.

The use of ultrasound in food processing creates novel and interesting methodologies, which are often complementary to classical techniques. In this work, the effect of heat and the combined treatment heat/ultrasound (thermosonication) on the thermal degradation kinetics of vitamin C in watercress (Nasturtium officinale) was studied in the temperature range of 82.5 to 92.5 °C. First order react...

Effects of two blanching conditions using peroxidase (POD) and lipoxygenase (LOX) as indicator enzyme on residual enzyme activities, ascorbic acid and chlorophyll content in green beans during frozen storage were studied. No reactivation of both LOX and POD enzyme was observed during storage. The losses of ascorbic acid and chlorophylls during storage followed first order kinetics. Half-life of...
