Food safety research and improvement of the technology of cottage cheese product with the use of green buckwheat.

The purpose of thе article is to study the safety indicators of the curd product, which includes cottage cheese prepared with a starter culture of direct application "Evitalia," consisting of bacteria of the genus Lactococcus (L. acidophilius), Streptococcus (Streptococcus thermophilius) and propionobacteria. Other ingredients are crushed mass from green buckwheat, candied pumpkin, cooked Jerusalem artichoke sirup, and fat emulsion based on coconut oil. The sweetness of the curd product is provided by Jerusalem artichoke sirup, whereas fat emulsion based on coconut oil enriches the product with unsaturated fatty acids and gives plasticity and uniformity of structure. The results of the study showed that the formulation with the following ingredients: 40% of cottage cheese, 40% of crushed mass from green buckwheat, 10% of candied pumpkin, 10% of coconut oil emulsion-has the best organoleptic, physico-chemical, structural and plastic properties. The ratio of milk protein of cottage cheese and vegetable protein of green buckwheat is 1:1. This allowed to obtain the chemical composition of the product: proteins-29%, fats-9%, carbohydrates-59%, ash-3%. The obtained research and technological solutions can be used at dairy industry enterprises in the production of combined dairy and vegetable products.

Optimism, Resilience, and General Self-Efficacy Predict Lower Somatic Burden during the COVID-19 Pandemic.

There is scarce evidence of a relationship between positive and psychosomatic characteristics. This study aimed to examine the associations of somatic burden with psychological resources such as optimism, resilience, and general self-efficacy. Russian participants (n = 1020) completed measures of psychological resources at Time 1 and somatic symptoms at Time 2. The results showed that somatic burden decreased with greater levels of optimism, resilience, and general self-efficacy. Regarding health and sociodemographic characteristics, female sex increased somatic burden in the model with optimism scores, university education decreased somatic burden in the model with resilience scores, and history of COVID-19 disease increased somatic burden in the models with optimism, resilience, and general self-efficacy scores. This study has theoretical and practical contributions. It combines positive psychology and psychosomatic medicine and highlights the value of psychological resource interventions in the treatment and prevention of somatic burden. These findings may be useful for scientists, clinicians, and practitioners.

Somatic burden in Russia during the COVID-19 pandemic.

Somatic burden has become one of the most common psychological reactions to the COVID-19 pandemic worldwide. This study examined the prevalence of somatic burden, latent profiles, and associated factors of somatic symptoms during the pandemic in a large sample of Russians. We used cross-sectional data from 10,205 Russians collected during October-December, 2021. Prevalence of somatic burden was assessed with the Somatic Symptom Scale-8. Latent profiles of somatic burden were identified using latent profile analysis. Multinomial logistic regression was used to examine demographic, socioeconomic, and psychological associated factors of somatic burden. Over one-third (37%) of the Russians reported being somatised. We selected the three-latent profile solution with high somatic burden profile (16%), medium somatic burden profile (37%), and low somatic burden profile (47%). The associated factors of greater somatic burden were female gender, lower education, history of COVID-19 disease, refusing vaccination against SARS-CoV-2 infection, poorer self-rated health, greater fear of COVID-19 pandemic, and living in regions with higher excess mortality. Overall, this study contributes to knowledge about the prevalence, latent profiles, and associated factors of somatic burden during the COVID-19 pandemic. It can be useful to researchers in psychosomatic medicine and practitioners in the health care system.
