: Affective-related disorders, including depression, are constantly rising, complicating people's personal lifestyle increasing disqualification and hospital care. Because of the high intensity of urbanization, our lifestyle and food have altered dramatically in the last twenty years. These food modifications have been associated with scores of depression and other affective-related disorders in urbanized countries with high economic levels. Nutrients imbalance is considered as one of the critical causes enabling the pathophysiological mechanisms for the development of psychiatric disorders. The application of additional nutritional interventions for treatment of mood deteriorations can be beneficial for both the prophylaxis and therapy of affective-related disorders. This paper will review recent research on the relation of Vitamin D levels and the epidemiology of depression in women. : In this paper, we will provide an overview of the results of a variety of different studies taking into account research which both suggests and refutes an association. Based on these findings we will propose important directions for future research in relation to this topic.

-Large amounts of dates are produced and consumed around the world each year. Apomyelois ceratoniae causes main losses during storage and export of date fruit. Fumigation is the most widely used treatment to prevent postharvest losses. However, this treatment negatively affects the biological value of dates, environmental and economic parameters of production. Widespread fumigation agent methyl bromide is toxic to a human body and contributes to the destruction of the ozone layer. The aim of the current work was to find a new method based on the use of low temperature refrigeration to reduce the pest and insect infestation preserving the nutritive value of dates during cold storage at the same time. A. ceratoniae mortality under different temperatures and dates respiration rate, sugar, organic acids, pectic substances content and sensorial characteristics were studied. The results indicate that at −18 °С the A. ceratonie larva dies within 2 h, the eggs and larvaewithin 24 h respectively. Thus, it is clearly shown that there is no need in using chemicals or irradiation to prevent dates pests. Physicochemical and organoleptic proprieties of dates were satisfactory during 360 d at −18 °С and during 180 d at +4 °С. The low temperature refrigeration and storage at −18 °С is recommended for dates to prevent pests and quality losses. It is apparently advantageous for environment and climate if compared with other anti-pest treatment variants.

This article provides data on the analysis of the properties of chitosan derivatives as a functional ingredient used in food technologies as a structure-forming agent, immunomodulator, enterosorbent of xantobiotics, anti-sclerotic and anti-arthritic factor, and as a regulator of the acidity of gastric juice. The expediency of the use of N-methylallyl-chitosan (chitosan derivative) as a substance that improves the functional-technological (moisture and fat-retaining power) and rheological properties of meat-and-vegetable emulsions is shown. The modes of micronising the emulsion depending on the chitosan derivative mass concentration, the speed of rotation of the knives of the microniser and the processing time were studied. Dependences on the change of moisture and fat-retaining power (MRP, FRP) and effective viscosity (η) on the above-mentioned parameters were investigated. The parameters of micronising were validated: the speed of rotation of the knives (υ) was 2500 rpm, the processing time (τ) was 60 s, υ was 3000 rpm, and τ was 50 s; also, the mass fraction of chitosan derivatives was 0.06%, which ensures the production of meat-and-vegetable emulsions of high quality.

BACKGROUND: Research on changes in the content of monomeric and dimeric phenolic compounds and their amount during freezing and storage of semi-finished products is relevant because the varieties of endive Cichorium endivia, which have many useful elements, are applicable for medical and dietary nutrition. AIM: This article aimed to analyze the kinetics of the oxidation and hydrolysis reactions of phenolic compounds of three varieties of endive during freezing and storage. MATERIALS AND METHODS: The total content of phenolic compounds and the amount of phenolcarboxylic acids and flavonoids in fresh vegetables and semi-finished products from Russian varieties Kruzhevo and Elvira endive, as well as the Italian variety Kornetto K-56, were determined by spectrophotometry in fresh endive after harvesting, then after homogenization, freezing, and periodically in the process of low-temperature storage. RESULTS: Kinetic dependencies of changes in the content of phenolic compounds on the duration of storage of semi-finished products from endive varieties Kruzhevo, Elvira, and Kornetto K-56 in a frozen state were revealed. The constants of the reaction rate (pseudo-first order) of the change in the content of the studied substances during storage of endive semi-finished products were calculated. To reduce the loss of cell sap during defrosting to maintain the amount of phenolic compounds during storage of endive semi-finished products, adding pectin in the homogenization stage at an amount of 3.0% by weight of the homogenized endive of the varieties under study is recommended. CONCLUSIONS: During storage of endive, phenolic compounds are preserved to the maximum, and cell sap losses are reduced within 180 days in the Elvira and Kruzhevo varieties, and within 150 days in the Kornetto K-56 variety. The frozen semi-finished product from homogenized endive of the studied varieties is recommended for use in healthy nutrition technologies, particularly in the production of low-calorie drinks and bakery and confectionery products.
