Pedada fruit contains 56.74 mg/100 g of vitamin C and 79% of water.  One of the uses of this fruit is for a raw material of fruit ice cream. Objectives of this research was to evaluate quality of fruit ice cream made from padada fruit and young coconut juice with addition of Carboxy Methyl Celulose (CMC). Randomized completely design with two factors was implemented in this research. The first factor was proportions of pedada fruit and young coconut juice consisting of three levels, that was i.e., 25%:75%, 50%:50%, and 75%:25%.  The second factor was CMC concentrations consisting of three levels, that was i.e., 0.1, 0.2, and 0.3%.  The best quality of fruit ice cream was obtained from 25% padada fruit juice and 75% young coconut juice with addition of 0.3% CMC.  The physical and chemical characteristics of the ice cream were a melting time of 11.11minute/10g, an overrun of 5.71%, a relative viscosity of 8.15 (Poiseuille x103), a fat content of 0.06%, a protein content of 1.29%, and a vitamin C content of 0.76mg/10g. The sensory characteristics of the ice cream were brownish, rather sour and sweet, and pedada-fruit aroma.

Tempe is a processed soy product that has been experiencing a decline in odor as a result of fermentation. Tempe juice beverage is one example of product diversification of food products based on tempe. Siam is one of the local fruits that are quite popular by the community and become the main commodity in West Kalimantan. In the process of making tempe juice, need to add a stabilizer CMC (Carboxy methyl cellulose) as much as 0.25% to produce quality tempe juice. The purpose of this research is to know the making of tempe juice extract with orange extract of siam (citrus nobilis) in terms of organoleptic quality, vitamin C level and isoflavone antioxidant activity level. The research method used experiment with 3 treatment of Siam orange extract 30%, 40% and 50%. The panelists used in the study were slightly trained panelists totaling 25 people. Based on statistical test, there is no effect of making tempe juice with orange extract (citrus nobilis) in terms of organoleptic quality based on color, flavor and taste. Due to the color -0.10 <3.23, the aroma is 2.42 <3.23 and the flavor is 0.17 <3.23. The results of this research is the addition of 50% more siam orange extract can be accepted by panelists. The results of this beverage viscosity were 30% concentration 0.40 dpas, 40% 0.34 dpas and 50% 0.32 dpas. Vitamin test results showed vitamin C content in tempe juice is 56.556 mg / 250 ml sample. Based on the results of isoflavone antioxidant activity test showed antioxidant levels 23%. Can be recommended as one of the beverages that contain antioxidants and vitamin C to meet the needs of the day and need to do further research on the storage power of tempe juice with the addition of orange extract.

Striae Gravidarum

Background: Striae gravidarum, a clinical condition commonly seen in pregnant women, produces serious cosmetic problems and may lead to psychological problems. Aim: The present study investigated whether there was any relation between the presence of striae in primigravid pregnant women and blood vitamin C levels, and factors thought to contribute to the formation of striae such as family history, weight gained during pregnancy, smoking status, abdominal and thigh circumference, and age. Methods: Overall, 69 primigravid women attending routine antenatal follow-up and, using prophylactic iron and vitamin preparations, underwent investigation. All were pregnant 36 or more weeks. Scoring was based on striae examination and whether striae were present. The relation between the presence of striae, vitamin C blood levels, and other factors was investigated. Results and Conclusions: Multiple logistic regression analysis showed a significant relation between the presence of striae and blood vitamin C levels (p = 0.046) and between the presence of striae and family history (p = 0.023). No significant relation was found between the presence of striae and age, weight gained during pregnancy, abdominal and thigh circumference, or smoking status. It was concluded that further, more comprehensive studies on the issue are required.

The Relationship

This study investigated the relationship between the intake of antioxidant nutrients and the suffering of cataracts in 177 institutionalized elderly people (61 men and 116 women) aged ≥ 65 years. Dietary intake was monitored for 7 consecutive days using a "precise individual weighing" method. Subjects, who during their earlier years were exposed by their work to sunlight, had a greater risk of suffering cataracts (OR = 3.2; Cl: 1.1–9.3, P < 0.05) than those who worked indoors. A relationship was found between increased vitamin C intake and a reduced prevalence of cataracts (i.e., when comparing those above P95 for vitamin C intake with those below P5; (OR = 0.08; Cl: 0.01–0.75, P 0.05). Among subjects with cataracts, 12.1% had vitamin C intakes of < 61 mg/day (P10) and only 2.2% had intakes of > 183 mg/day (P95) (p < 0.01). Subjects who consumed > 3290 μg/day (P95) of lutein were less likely to have cataracts (OR = 0.086; Cl: 0.007–1.084; p < 0.05) than those whose consumption was < 256 μg/day (P5). In men, high intakes of zeaxanthin seemed to provide a protective effect against the problem (OR = 0.96; Cl: 0.91–0.99; p < 0.05). The results suggest an association exists between exposure to sunlight and the development of cataracts, and that vitamin C, lutein, and zeaxanthin offer some protection against this disorder.

Abstract. Background: Vitamin C is a strong antioxidant, and the health effects of vitamin C megadoses have not been validated despite the apparent health benefits. Therefore, the present study sought to confirm the effects of vitamin C megadoses. Materials and Methods : Four groups of six guinea pigs were used. Each group was fed one of the following diets for three weeks: normal diet, methionine choline-deficient diet, methionine choline-deficient diet + vitamin C megadose (MCD + vit C 2.5 g/kg/day), and methionine-choline deficient diet + ursodeoxycholic acid (MCD + UDCA 30 mg/kg/day). The MCD diet was given to induce nonalcoholic steatohepatitis, and UDCA was used to treat nonalcoholic steatohepatitis. Three weeks after initial diet administration, the results of biochemical tests and liver biopsy were compared between the groups. Results: The cytoplasm state was similar in the MCD + vit C and MCD + UDCA groups, exhibiting clearing of the cytoplasm and ballooning degeneration. However, macrovesicular steatosis was not observed in the MCD + vit C group. Aspartate transaminase and alanine transaminase were elevated significantly following vitamin C administration. Conclusions: The present study confirmed that alone vitamin C megadoses are potential remedies for nonalcoholic steatohepatitis, based on the liver biopsy results of guinea pigs that were unable to synthesize vitamin C.

Konsum und Kontrolle: Wie Vitamin C zu einem Allheilmittel werden konnte

Vitamin C

Zusammenfassung. Künstliches Vitamin C ist heute ein Massenprodukt. Dass sich Ascorbinsäure seit ihrer Erfindung 1933 zu einem alltäglichen Konsumgut mausern konnte, ist weniger durch ihr medizinisches Potential zu erklären, sondern verdankt sich vielmehr einem dynamischen Zusammenspiel von Produktion, Vermarktung und Gesundheitspolitik. Der Beitrag fokussiert insbesondere auf die komplexen Interaktionen zwischen Gesundheitskonzepten, diagnostischen Instrumenten und ärztlichem Blick. Dabei scheinen nicht nur die Differenzen zwischen „rein naturwissenschaftlichen“ und „ärztlich-biologischen“ Standpunkten auf, sondern es zeigt sich auch, dass Nahrungsbestandteile immer auch gesundheitspolitisch und ethisch aufgeladen sind.
