“…У світовій індустрії HoReCa основним апаратом для термічної обробки наразі є пароконвектомат -універсальне теплове обладнання з широким спектром функцій, високим ступенем автоматизації, можливістю програмування технологічного процесу. Пароконвектомати уможливлюють задавати і контролювати температуру, вологість, швидкість руху повітря в робочій камері та час теплової обробки, що дає змогу зменшити вплив стану якості сировини і стабілізувати якість продукту та забезпечити його безпечність [3].…”

Background. The main aspects of quality assessment of fish raw materials and combi ovens for its heat treatment are considered. The results of connection researches of structural and mechanical properties of raw materials with its thermophysical characteristics and parameters of necessary culinary processing are presented. The expediency of using physical methods for assessing the quality of raw materials to predict the mode of heat treatment is determined. The aim of the study is to develop a system of rapid diagnostics of structural-mechanical and thermophysical properties of fish semi-finished products for the institutions of the HoReCa industry. Materials and methods. The object of research is the structural-mechanical and thermophysical properties of grass carp and their changes during storage. The subject of research – culinary semi-finished products, specifically – grass carp steaks. Determination of structural and mechanical properties of steaks was carried out by a measuring sensor of original design, developed on the basis of components of ITM LLC. The heating kinetics of grass carp semi-finished products were performed in a PolEco cabinet at a temperature of 180 ºC and forced convection. The temperature in the samples was recorded by standard thermal sensors of the UMCD with a measurement period of 20 seconds. The amount of active electricity, consumed for the preparation of steaks, was determined excluding the reactive component, by using current measuring clamp. Culinary processing of steaks was in the steam convection oven Convotherm OEB 6.10. Results. A set of structural and mechanical properties of grass carp steaks with different shelf life was determined with a sensor of the original design of UMCD. The correlation of changes in the indicators of adhesion, penetration and relaxation force after compression with the shelf life of steaks was established. A correlation between the shelf life and the heating speed of the samples was established with a standard thermo sensors of UMCD. The heating speed of the samples after 24 h of storage increases by 10–11 %. By recording the current in the power cable of the combi steamer, the electricity consumption for cooking 12 portions of steaks (2400 g) was determined. The possibility of saving electricity from 4.6 % for cooking freshly asleep fish and up to 16.5 % for chilled fish stored for 24 hours was established. Conclusion. The measuring sensor was tested. It allows determining the relaxation, strength and adhesion of fish raw materials in the express mode. It was found that the structural-mechanical and thermophysical properties of grass carp change with storage time. It is experimentally confirmed that the change of information parameters of heat treatment in the steam convection oven is a criterion of quality of culinary products from freshwater fish. The developed method of express diagnostics allows determining the rheological properties of raw materials from freshwater fish and optimizing the heat treatment of culinary products in restaurants in terms of differential quality of raw materials. Due to the selection of individual processing modes for fish raw materials of different consistency and shelf life, it is possible to reduce electricity consumption by the steam convection oven by 4.6–22.4 %.

Hyperthermia has been studied as a noninvasive cancer treatment. Cancer cells show stronger thermal cytotoxicity than normal cells, which is exploited in hyperthermia. However, the absence of methods evaluating the thermal cytotoxicity in cells prevents the development of hyperthermia. To investigate the thermal cytotoxicity, culture temperature should be regulated. We, thus, developed a culture system regulating culture temperature immediately and accurately by employing metallic culture vessels. Michigan Cancer Foundation-7 cells and normal human dermal fibroblasts were used for models of cancer and normal cells. The findings showed cancer cells showed stronger thermal cytotoxicity than normal cells, which is quantitatively different from previous reports. This difference might be due to regulated culture temperature. The thermal stimulus condition (43 °C/30 min) was, further, focused for assays. The mRNA expression involving apoptosis changed dramatically in cancer cells, indicating the strong apoptotic trend. In contrast, the mRNA expression of heat shock protein (HSP) of normal cells upon the thermal stimulus was stronger than cancer cells. Furthermore, exclusively in normal cells, HSP localization to nucleus was confirmed. These movement of HSP confer thermotolerance to cells, which is consistent with the different thermal cytotoxicity between cancer and normal cells. In summary, our developed system can be used to develop hyperthermia treatment.
