Dietary dragon fruit (Hylocereus undatus) peel powder improved in vitro rumen fermentation and gas production kinetics

Plant phytophenols especially condensed tannins (CT) and saponins (SP) have been demonstrated to impact on rumen fermentation. Dragon fruit (Hylocereus undatus) peel powder (DFPP) contains both CT and SP. The current study aimed to investigate the influence of DFPP and varying levels of concentrate and roughage ratios on gas production kinetics, nutrient degradability, and methane production “using in vitro gas production technique.” The dietary treatments were arranged according to a 3 × 5 Factorial arrangement in a completely randomized design. The two experimental factors consisted of the roughage to concentrate (R:C) ratio (100:0, 70:30, and 30:70) and the levels of DFPP supplementation (0, 1, 2, 3, and 4% of the substrate) on DM basis. The results revealed that the R:C ratio at 30:70 had the highest cumulative gas production when compared to other ratios (P < 0.01). The in vitro true dry matter degradability at 12 and 24 h was affected by R:C ratio (P < 0.01). Furthermore, volatile fatty acids (VFA) and propionate (C3) were significantly increased by the levels of DFPP, while acetate (C2) and C2:C3 ratios were decreased (P < 0.05). The rumen protozoal population was significantly decreased by DFPP supplementation (P < 0.05). Rumen methane production was significantly impacted by R:C ratios and decreased when the level of DFPP increased (P < 0.01), while NH3-N and ruminal pH were not influenced by the DFPP supplement. It could be summarized that supplementation of DFPP resulted in improved rumen fermentation kinetics and could be used as a dietary source to mitigate rumen methane production, hence reducing greenhouse gas production.

Dissipation pattern of azoxystrobin and difenoconazole in red dragon fruit (Hylocereus polyrhizus) cultivated in Indonesian highland (West Java) and coastal area (D.I. Jogyakarta) and its implication for dietary risk assessment

Background
Cultivation of red dragon fruit (Hylocereus polyrhizus) in Indonesian orchards is hampered by anthracnose and stem canker. A mixture of azoxystrobin 200 g/L + difenoconazole 125 g/L is recommended in supporting the obligated integrated pest management. For the consumer safety, dietary intake of the residues from fresh edible part should be assessed; therefore, information on correct dissipation pattern of the applied pesticide is required.
Materials and Methods
Field residue trials in Indonesian highland (West Java) and coastal area (Special Region of Yogyakarta) were done at recommended dose was 0.151 kg ai/ha azoxystrobin and 0.094 kg ai/ha difenoconazole, three times at 10 days interval. Whole fruit samples were collected at 70%–100% ripeness at −1, 0, 1, 3, 7, 10, and 14 days after last application, processed and determined its residue as soon as possible.
Result and Discussion
Photoisomerization of azoxystrobin was observed at Day 0, especially in coastal area; however, it has been dissipated to below lowest validated level in the following day. At Day 0, 3%–5% of the deposited azoxystrobin and difenoconazole penetrate into the flesh; however, most residues (95%–97%) were retained in peel, and dissipated in prolonged day. The dissipation pattern was non-linear. The dissipation data were better fit with bi-exponential double-first-order in parallel than single first-order kinetics model. The DT50 of both azoxystrobin and difenoconazole was 3 days. At harvest time, seventh day, only azoxystrobin residue was detected in flesh at 0.006 mg/kg; therefore, the long-term dietary risk was 0 per cent acceptable daily intake.
Conclusion
Fresh red dragon fruit is safe to consume.

DRAGON FRUIT SKIN FOR OVERCOME PAIN WHEN MENSTRUATION (DISMENOREA)

Menstrual pain, or medical dysmenorrhea, is pain in the lower abdomen during menstruation and can also be felt on the hips, lower back, or thighs. The pain is convulsive (convulsions), which are felt by some women at the beginning of menstruation. Dysmenorrhoea can also be overcome non-pharmacologically, which can naturally reduce the intensity of the pain. This research is an experimental analytical research that is a research on the level of naturalness (setting) where research is in addition to survey research and naturalistic (qualitative). Essentially, experimental research is to examine the effect of the treatment on the behavior that results from the treatment. This study was conducted to determine the intensity of menstrual pain after eating dragon fruit skin juice. The first 3 months focused on reducing the intensity of pain after eating dragon fruit skin juice with a composition of 100 grams of dragon fruit skin mixed with sugar and enough water. The second 3 months focused on reducing the intensity of pain after eating dragon fruit skin juice with a composition of 200 grams of dragon fruit skin mixed with sugar and sufficient water. The third 3 months focused on reducing the intensity of pain after eating dragon fruit skin juice with a composition of 100 grams of dragon fruit skin mixed with milk and sufficient water. In addition, the study also received information on how to reduce the intensity of menstrual pain by applying non-pharmacological techniques by using dragon fruit
