We report both experimental measurements and molecular simulations of the melting freezing behavior simple fluids in porous media. The studies are for carbon tetrachloride nitrobenzene controlled pore glass (CPG) Vycor. Differential scanning calorimetry (DSC) was used to determine point materials each samples. In case (which has a nonzero dipole moment), dielectric spectroscopy also points. Measurements by two methods were excellent agreement. found be depressed relative bulk value fluids....

The antioxidant capacity (AC) of boiled-type coffee brews (CB) and phenolic acids (PA) isolated from them, obtained the caffeinated decaffeinated beans different geographical origins species with roasting degrees, was examined. AC PA CB samples tested in five assays: a total antioxidants reducing assay using Folin–Ciocalteu reagent (FCR), ferric ion power (FRAP) assay, DPPH· radical-scavenging activity (DPPH) metal chelating (MCA) radical trapping parameter (TRAP) assay. In most samples,...

The oxidative stability of vegetable oils mainly depends on their fatty acid composition, degree unsaturation, and the presence compounds with antioxidant activity. This paper reports effects process roasting oil seeds, prior to pressing them, basic characteristics produced stability. differential scanning calorimetry (DSC) technique was used study oxidation samples in an oxygen-flow cell. Chromatographic analysis revealed that seeds increased levels chlorophyll β-carotene all cold-pressed...

The aim of this study was to test selected factors, such as sample preparation and measurement procedure, potentially influencing repeatability DSC analysis milk fat melting crystallization. investigated the effect factors scanning rate, type pans, method butter dehydration, final temperature in cooling experiment. Based on recorded results, it observed that rate has a considerable temperature, enthalpy, height peaks process crystallization, well peak enthalpy process. By contrast, no...

The cold-pressed oil from Japanese quince seeds (JQSO) is notable for its favorable fatty acid profile, low oxidation rate, and bioactive compounds like antioxidants, sterols, carotenoids. This study offers a detailed molecular-level physical characterization of JQSO minor components using differential scanning calorimetry (DSC), Langmuir monolayer studies, various spectroscopic methods, including UV–vis absorption, fluorescence, FTIR. DSC analysis identified five peaks related to...

Triticale is a hybrid obtained by crossing wheat with rye. One of the factors limiting its application into food industry still lack knowledge about this cereal. The aim study was to characterize and compare features triticale starch from grain five new Polish varieties: Madilo, Baltiko, CHD 3012/99, Pizarro Fredro. Starch content in analyzed cultivars varied narrow range, while differences falling number values, spite same growing condition, more significantly. All investigated starches had...

The effects of black seed (

The characteristics of six cold-pressed raspberry seed oils, investigated by melting and crystallization phase transition analysis using differential scanning calorimetry (DSC), UV-VIS Fourier transform infrared (FTIR) spectra, as well the fatty acid composition, was aim this study. Two groups oils samples were investigated: commercial (I-group) laboratory-pressed (L-group). UV/VIS FTIR spectra oil revealed important wavelength wavenumber ranges to indicate qualitative differences between I-...

The aim of this study was to investigate the quality changes raw ground pork with addition allspice, bay leaf, black seed, caraway, cardamom, cloves or nutmeg extract and stored at 4°C. Lipid oxidation evaluated by peroxide value (POV), conjugated diene (CD) content, induction period (IP) differential scanning calorimetry (DSC), thiobarbituric acid reactive substances (TBARS), hexanal content; whereas protein thiol group content. Moreover, total viable aerobic bacteria count (TVC),...

Deep pectoral myopathy (DPM) of musculus pectoralis minor is an anomaly observed in gallinaceous poultry. To date its cases have been reported adult pedigree turkeys and hens recent years also broiler chickens. This degeneration manifested abnormal appearance breast muscles, with changes colour from pink to green, as well the texture muscle tissue. The found most frequently genetic lines chickens characterised by dynamic weight increment rearing period a considerable increase proportion...

The aim of this study was to examine the thermal denaturation properties proteins from fresh and frozen pond mussels Anodonta woodiana by differential scanning calorimetry (DSC). A. (Lea, 1834) were collected bottom a lake located in West Poland. Three parts mussel: adductor muscle (AM), foot (FO) part internal organs (IO), taken for analysis. DSC technique used characterize stability protein system, SDS-PAGE applied separation identification proteins. Thermal analysis all mussel revealed...

The aim of this study was to describe the thermal properties selected cultivars flaxseed oil by use differential scanning calorimetry (DSC) technique. crystallization and melting profiles were analyzed depending on different rates (1, 2, 5 °C/min) as well oxidative induction time (OIT) isothermally at 120 °C 140 °C, oxidation onset temperatures (Ton) 2 °C/min measured. manifested a single peak, differing for cooling rate 1 °C/min. curves more complex with differences among heating °C/min,...

Steady-state emission spectroscopy of 1-anilino-8- naphthalene sulfonate (ANS) and 1,6-diphenyl-1,3,5-hexatriene (DPH), fluorescence anisotropy, DSC methods were used to characterize the interactions newly synthesized 1-carba-alpha-tocopherol (CT) with a 1,2-dipalmitoyl-

Quality variation in oxidative stability between raspberry seed oils produced by industry and manually-pressed laboratory was investigated. Oxidation induction time measured differential scanning calorimetry (DSC) at 120 140 °C for industrial ranged from 60 to 100 min 14 26 min, respectively, while laboratory-pressed oils, 96 106 23 28 respectively. Both groups of contained a high amount tocopherols, ranging 95 256 mg/100 g, where γ-tocopherol dominated up 70% the total tocopherols....
