The effect of proteolytic and cytolytic enzymes, as well as extraction time, on the efficiency of selenium extraction from vegetable materials was evaluated. The materials containing selenium to be extracted were Chinese lettuce (Brassica rapa) of pak-choi variety and amaranth (Amaranthus caudatus L.) of Kharkovskiy variety, both undergone selenium enrichment via agrochemical cultivation. A single water solution of DistizymProtacid Extra (proteolytic) and Viscostar (cytolytic) enzymes served as the extracting agent. Said solution was introduced into samples, with the exception of two control samples, in such quantities that the dosage of non-diluted enzymes was 1 µl each enzyme to 1 g sample. Accounting for the dilution, the resulting dosage was 1 part water solution to 12 parts vegetable material. Extraction time amounted to 24 hours. The temperature of extraction was either 45°C or 55°C. Selenium content in the extracts obtained was determined according to GOST R 53182–2008. It was found that the amount of dry matter in extracts became larger as extraction process continued. The maximum of dry matter content in pakchoi lettuce and amaranth extracts was achieved at non-zero enzyme dosage (1 µl per 1 g) and the extraction temperature of 55°C and was equal to 7.40 g?100 cm–3and 2.95 g?100 cm?3 dry matter, respectively. Selenium content in all extracts amounted to 257.3 µg?dm?3 at 45°C and 284.9 µg?dm?3 at 55°C; in amaranth extracts 325.8 µg?dm–3 (45°C) and 347.0 µg?dm?3 (55°C). The results obtained may be further applied to preparation of food adjuncts and functional foods.

Получение селенсодержащих экстрактов из растительного сырья

Marriage aims not only to obtain social acceptance but also to have a long-lasting companionship. Longdistance marriage is a relationship between husband and wife that is both legally and religiously bound. In this research, three samples are used: one sample is an employee, one sample is a lecturer, and one other sample is a university student. In more detail, the samples are: N (26) with a husband working in Cikarang, P (28) is an employee whose husband working in Makassar, and R (35) is a university student whose husband working in Kendari. The research aims to identify the role of husbands in long-distance marriage life and the wives' expectations in living with this marriage. The research methodology used in this research is interview involving instructions and open questions. The result of this research shows that the three samples experienced problems in communicating, so they often had an argument, suffered from loneliness, and lacked the husband’s participation in parenting.

A Perspective of Husband and Wife Roles in Long-Distance Marriage

Marriage patterns and reproductive behavior in Russia have undergone important changes in recent years, with profound implications for the nation as a whole. New public policies may be necessary to deal with the consequences.
