Purpose: More than 100 plant species have been classified as oil products, but only a few of them are used in industrial production. In the available literature, there are no studies that would describe the relationship between the content of plant dyes and their impact on auto-oxidative processes. Therefore, this study aimed to determine dye composition and to define their effect on the acid value, peroxide value and quality assessment of selected refined and unrefined oils. Materials and methods: Twenty samples from different manufacturers were evaluated. Oils were purchased from retail trade of the Bialystok city. The total colour, acid, and peroxide values were determined in accordance with the Polish Standards PN-ISO 3960: 1996, PN-A-86934: 1995 and PN-ISO 3960: 1996, respectively. Results: Statistically significant differences of total colour values between both groups were found (p=0.002). The acid value of refined oils was lower than in an unrefined group (p=0.02). A positive statistically significant correlation was noticed between the total colour value and the acid value in the refined group (R=0.65, p=0.04). No significant effect of plant dyes on the acid or peroxide value of unrefined oils was observed. Conclusions: Refined and unrefined oils purchased in the city of Bialystok mostly met the standard values with the exception of cold-pressed oil from black cumin seeds, where the acid and peroxide value exceeded the values set in Codex Alimentarius.

Purpose: Respiratory tract infections and severe allergy reactions are a leading cause of hospitalization and morbidity in infants and children. The protection of breastfeeding against infectious diseases as well as allergy development has often been suggested. The aim of the study was to assess the relationship between the various models of infant nutrition, its immunity influence and children response after 3-6 years of age. Materials and methods: The research was based on a voluntarily questionnaire, filled in by parents of pre-school children. Information on breast and milk formula feeding duration (never; 1-6 months; 6-12 months; 12-24 months; 24>months) were collected. The frequency of infections, chronic diseases, and allergies occurrence was analysed. Results: A statistically significant differences between infants breastfeeding and milk formula feeding in case of reduced infection (p=0.003) and infection recurrences (p=0.001) were found. This relationship was not found among children at further stages of development. There was no correlation between the consumption of only mothers’ milk, and the reduced occurrence of asthma, allergies, and eczema. Conclusions: Maternal milk has an influence on the reduced risk of infection in the first year of the child’s life compared to children fed only with artificial mixtures
