Избыточное потребление сахара (более 65 г в сутки) является причиной ряда неинфекционных заболеваний, вызванных быстрым ростом содержания глюкозы и инсулина крови. В России превышает рекомендуемый уровень не менее чем 1,4 раза. связи с этим существует необходимость замены сахарозы на ингредиенты пониженным гликемическим индексом калорийностью. Целью исследований являлось экспериментальное обоснование состава мороженого со сниженным содержанием сахарозы. Исследовали образцы молочного жира 10...

An effective mode register is method differential scanning calorimetry (DSC). As result studies differences during pork, beef, chicken and turkey were defined by appearance endothermic peaks DSC thermograms. The main variances are associated with myosin sacroplasmic indicate indirectly their quantitative ratio meat. values specific heat capacity 20 obtained as well...

As a consequence of insufficient study water phase change in meat accompanied by crystallization, its modeling is currently based on the empirical dependence frozen portion temperature. Such model does not allow answering number questions such as metrological order, and also physicochemical interpretation processes occurring during crystallization. In this paper, we propose an approach to process freezing basis phonon theory Debye which allows obtain physically justified dependences heat...

Alzheimer's disease (AD) causes pronounced hippocampalatrophy, as measured by structural magnetic resonance imaging (sMRI). Studies using resting-state functional MRI (rs-fMRI) have also revealed that AD disrupts connectivity within the brain's default-mode network, which: -36px; font: normal 12px/normal arial; '' > hypometabolism during early stages of AD). However, current understanding regarding effects on hippocampus is limited. The goal present study was to examine whether alters...

The production of enriched fermented milk products with a long shelf life using ice cream technology makes it possible to expand the range functional due varieties used in thawed form. An important feature is use gel-forming stabilizers capable retaining moisture and maintaining gel structure after thawing. formation product high dispersion structural elements preservation air phase defrosted state are facilitated by process simultaneous saturation mixture freezing, adopted cream. based on...

Speakers discuss how data is stored, shared, and monetized connecting an entire ecosystem with benefits. In addition, EHRs, genomic DNA, wearables, pharmacy social determinants of health accelerated access to de-identified, tokenized, real-time addressed in shaping a new economy.

The paper proposes a model for the process of free moisture crystallization in beef within framework Debye concept with establishment dependencies parameters on initial content. Model adequacy was validated by comparison calculation results experiments determination values heat capacity and phase transition enthalpy different obtained differential scanning calorimetry method. It is shown that end water range 37% to 80% occurs at temperature 243 К. Calculation used are presented.

A multi-modal imaging approach was applied to understand alterations in the default-mode network from normal aging mild cognitive impairment (MCI) and Alzheimer's disease (AD). Participants included 10 probable AD, 11 amnestic MCI, 12 age education-matched control (NC) subjects. Whole-brain resting-state functional, diffusion tensor volumetric MRI as well FDG-PET data were acquired.

Мороженое сливочное и пломбир является наиболее производимым. Традиционно для стабилизации структуры мороженого используют комплексы стабилизаторов-эмульгаторов, содержащие 4–6 пищевых добавок. Что ограничивает потребление этих разновидностей у определенной категории людей. Целью исследований являлось установление возможности применения цитрусовых волокон их композиции с гуаровой камедью взамен эффективных стабилизаторов-эмульгаторов в производстве ограниченным содержанием В качестве...

Ice cream is a popular cold dessert. Its air phase consists of tiny bubbles with an average diameter 15–60 µm. New ice formulations depend on the way composition and production factors affect phase. As result, producers need new time-saving reliable methods to determine dispersion. The research objective was create computer program for marking position centers microscopic images bounding circle type.
