Abstract

Background : Apples are known to contain antioxidants and vitamin C, which play important roles in protecting the body from oxidative stress and degenerative diseases. However, vitamin C is sensitive to heat, light, and oxygen, which can lead to degradation during processing. Objective : This study aimed to compare the vitamin C content of Rome Beauty apple (Malus sylvestris Mill) in various processed forms commonly consumed by the public, including fresh apple, apple juice, cider, dodol, and apple chips. Research Methods/ Implementation Methods : The research was conducted using a titrimetric method with 2,6-dichlorophenol-indophenol dye to determine vitamin C content. Five samples were analyzed in duplicate. The data were statistically tested using the Kruskal–Wallis and Mann–Whitney tests to evaluate differences among samples. Results : The vitamin C content ranged from 2.85 to 12.36 mg/100 g. The highest content was found in fresh apples (12.36 mg/100 g), followed by apple juice (6.41 mg/100 g), apple extract (5.23 mg/100 g), apple dodol (2.85 mg/100 g), and apple chips (2.85 mg/100 g). Statistical analysis showed significant differences (p < 0.05) among the samples, particularly between fresh or juiced apples and processed forms such as dodol and chips. Conclusion/Lesson Learned : Processing significantly reduces the vitamin C content of Rome Beauty apples. Heat treatment, oxidation, and exposure to air during processing are the major factors contributing to vitamin C loss. Therefore, consuming fresh apples provides the greatest nutritional benefit in terms of vitamin C intake.

Abstract

Background and aims: Type 2 diabetes (T2D) patients are at risk of developing cardiovascular diseases (CVD). Arrowroot cookies with porang glucomannan which are rich in dietary fiber may be able to reduce CVD risk in T2D patients. This study aimed to evaluate the effect of cookies consumption for 8 weeks on the atherogenic index of plasma (AIP) of T2D patients. Material and method: As many as 24 T2D subjects were recruited from primary health centers in Yogyakarta. The control group (n=12) was given nutrition education, and the intervention group (n=12) was given nutrition education and 5 pieces of cookies (65 grams) as snacks for 8 weeks. AIP [log(TG/HDL-C)], anthropometry, and food intake were measured before (week 0) and after (weeks 8) the study. Results: There was a decrease in AIP in the intervention group from 0.189 to 0.164 (medium-risk of CVD), although it wasn’t significant (p>0.05). On the contrary, the AIP level in the control group increased from 0.075 (low-risk of CVD) to 0.111 (medium-risk of CVD). The AIP changes between groups were not significantly different (p>0.05). There were no changes in anthropometry measures in both groups after the study (p>0.05). We found an increase in dietary fiber intake in both groups (p<0.05), however, it was not significantly different between groups (p>0.05). Conclusions: Consumption of 65g arrowroot cookies with porang glucomannan addition for 8 weeks did not significantly affect the AIP in T2D patients. However, it could maintain the AIP level in the intervention group in the medium-risk category.

Abstract

Background : Exclusive breastfeeding during the first six months of life is essential for optimal infant growth, development, and disease prevention. However, the coverage of exclusive breastfeeding remains below national and regional targets in many areas of Indonesia Objective : This study aimed to analyze the determinants of exclusive breastfeeding among mothers with infants aged 6–24 months in the working area of Puskesmas Waru, Penajam Paser Utara Regency, East Kalimantan Province. Methods : An observational analytic study with a cross-sectional design was conducted among 122 mothers selected using simple random sampling from a population of 345 mothers. Data were collected using structured questionnaires measuring maternal knowledge, maternal attitude, early initiation of breastfeeding (IMD), maternal occupation, family support, health worker support, and exclusive breastfeeding practices. Data were analyzed using Chi-square tests with a significance level of α = 0.05. Results : The results showed that 44.3% of mothers practiced exclusive breastfeeding, while 55.7% did not. Maternal knowledge (p = 0.000), maternal attitude (p = 0.000), and family support (p = 0.000) were significantly associated with exclusive breastfeeding. In contrast, maternal occupation (p = 0.875) and health worker support (p = 0.083) were not significantly associated with exclusive breastfeeding Conclusions : These findings indicate that behavioral and social factors play important roles in influencing exclusive breastfeeding practices. Strengthening health promotion programs that improve maternal knowledge, foster positive breastfeeding attitudes, and enhance family involvement is essential to increase exclusive breastfeeding coverage.
