5-Hydroxymethylfurfural (HMF) formation during subcritical water extraction
The aim of this study was to investigate the
effect of material type (artichoke leave, lemon peel, flaxseed meal), extraction temperature (50, 100, 120, 140, 160,
180, 200 C) and static extraction time (5, 15, 30, 45 min)
on 5-hydroxymethylfurfural (5-HMF) formation during
subcritical water extraction. 5-HMF content of artichoke
leave and lemon peel extracts increased 7.2 and 26.1 times
with the rise of extraction temperature from 160 to 180 C
for 5 min during subcritical water extraction, respectively.
Besides, 5-HMF content of artichoke leave, lemon peel and
flaxseed meal extracts increased 1.4, 2.0 and 4.5 times as
static extraction time increased from 15 to 45 min at
180 C during subcritical water extraction, respectively.
The highest 5-HMF content of artichoke leave and lemon
peel extracts were obtained as 58.83 and 231.21 mg/L at
180 C and 45 min, respectively. However, for flaxseed
meal, the highest 5-HMF content (222.94 mg/L) was
obtained at 200 C and 15 min during subcritical water
extraction.Project Nos. 2014.M80.02.03, 2014.M80.02.04 by Artvin Coruh University Scientific Research Project Uni
Correlates of Out-of-Pocket and Catastrophic Health Expenditures in Tanzania: Results from a National Household Survey.
Inequality in health services access and utilization are influenced by out-of-pocket health expenditures in many low and middle-income countries (LMICs). Various antecedents such as social factors, poor health and economic factors are proposed to direct the choice of health care service use and incurring out-of-pocket payments. We investigated the association of these factors with out-of-pocket health expenditures among the adult and older population in the United Republic of Tanzania. We also investigated the prevalence and associated determinants contributing to household catastrophic health expenditures. We accessed the data of a multistage stratified random sample of 7279 adult participants, aged between 18 and 59 years, as well as 1018 participants aged above 60 years, from the first round of the Tanzania National Panel survey. We employed multiple generalized linear and logistic regression models to evaluate the correlates of out-of-pocket as well as catastrophic health expenditures, accounting for the complex sample design effects. Increasing age, female gender, obesity and functional disability increased the adults' out-of-pocket health expenditures significantly, while functional disability and visits to traditional healers increased the out-of-pocket health expenditures in older participants. Adult participants, who lacked formal education or worked as manual laborers earned significantly less (p < 0.001) and spent less on health (p < 0.001), despite having higher levels of disability. Large household size, household head's occupation as a manual laborer, household member with chronic illness, domestic violence against women and traditional healer's visits were significantly associated with high catastrophic health expenditures. We observed that the prevalence of inequalities in socioeconomic factors played a significant role in determining the nature of both out-of-pocket and catastrophic health expenditures. We propose that investment in social welfare programs and strengthening the social security mechanisms could reduce the financial burden in United Republic of Tanzania
