Deterioriation of palm oil fortified with vitamin A and provitamin A could be caused by the presence of oxygen and light exposure. The purpose of this study was to determine the effect of the initial peroxide value (PV) in palm oil (1.99, 3.98, and 9.95 meq O2/kg oil) and light intensity (15000, 10000, and 5000 lux) on the rate of oxidation and the shelf life of palm oil fortified with Red Palm Oil (RPO) equal to 45 IU vitamin A. The RPO contained β-carotene as provitamin A in the amount of 504.67 ppm. The PV and free fatty acid (FFA) content were observed as the parameters of oil deterioriation during storage. The results showed that the rate of PV was influenced by light intensity, while the rate of FFA formation were more influenced by the amount of initial PV in the oil. Based on the palm oil standard quality for PV (SNI 7709: 2012), the shelf life of palm oil with the lowest initial PV at ambient temperature was 9.5 days, while that with the highest PV was 1.32 hours. The deterioration rate of RPO fortified palm oil due to light exposure was also compared with its deterioration rate due to heat and the deterioration rate of palm oil fortified with vitamin A. The shelf life of vitamin A fortified palm oil stored in the dark was 90.67 days, while RPO fortified palm oil was 68.12 days. This shelf life results showed that RPO had a potency as provitamin A fortificant for palm oil as long as it is stored in a closed container in the dark.

Cardiovascular disease is related to the high consumption of trans fatty acid. This issue has driven SEAFAST IPB Laboratory to develop a trans fatty acid analysis method for gas chromatography based on AOCS Official Method Ce 1h-05. This research was aimed to validate the method via three steps: preparation step, procedure orientation test, and method validation. During instrument performance testing in the preparation step, linearity, limit of detection (LoD), limit of quantitation (LoQ), range, and precision parameters were validated for FAME 9t-C18:1 and C18:2 isomer mixed standard solution. During the method validation step, specificity, precision and accuracy parameters were validated for 9t-C18:1 compound attached to food matrix, i.e. doughnut. The instrument validation result of 9t-C18:1 standard solution had fulfilled the criteria of linearity (r2=1, requirement r2 > 0.990) within the range of 0.0020 to 0.1200 mg/mL; precision (RSD) 0.24%; LoD 0.0007 mg/mL and LoQ 0.0020 mg/mL. The instrument validation result for each isomer in C18:2 standard solution also met the criteria of linearity (r2= 0.9999, requirement r2 > 0.990) with precision (RSD), LoD and LoQ respectively; 1) 9t,12t-C18:2: 1.40%; 0.0033 mg/mL; 0.0100 mg/mL; 2) 9t,12c-C18:2: 1.89%; 0.0015 mg/mL; 0.0045 mg/mL; 3) 9c,12t-C18:2: 2.39%; 0.0015 mg/mL; 0.0044 mg/mL; 4) C18:2 cis: 3.39%; 0.0006 mg/mL; 0.0019 mg/mL. The validation result for 9t-C18:1 in 100 mg fat extract of doughnut suggested that the modified method is validated in term of specificity (Rs = 1.2), precision (RSD fatty acid content (mg/g) = 1.78%; RSD percentage of fatty acid content towards total fatty acid = 0.72%) and accuracy (as percentage of recovery) 80.54-94.25%.

Cinnamon has been used as a traditional treatment for thousands of years. Aqueous cinnamon extract namely cinnulin is known to have positive effects on type-2 diabetes mellitus (T2DM). We aimed to study the effect of cinnulin enriched drink rich in polyphenols on plasma malondialdehyde (MDA), interleukin-6 (IL-6) and cyclooxygenase-2 (COX-2) in T2DM patients. 255 mg of cinnulin was mixed with tea extract into a 2.5 gram of instant drink with alumunium foil as the packaging material. A single blind study were performed on 33 respondents with T2DM from Dramaga District. Respondents were divided into three groups, i.e. group given cinnulin enriched drink (1), instant tea drink (2), and none of the products (control) (3). Group 1 and 2 were assigned to drink two sachetsof the products a day for 5 weeks. The MDA content of all groups remain unchanged after treatment although slightly increased (Wilcoxon, P>0.050) and no differences between groups was observed (P>0.050) suggesting that high phenolic content in the producst cause a reverse effect. Both inflammation marker (IL-6 and COX-2) decreased significantly for groups given cinnulin enriched drink and instant tea, whereas there is a significant increase for IL-6 and a significant decrease for COX-2 in control group. These results conclude that cinnulin enriched drink can be used as an antiinflammation drink for T2DM.

The utilization of sorghum as food products is restricted by its lack of digestibility and the presence of anti-nutrients factors. Fermentation process has been recommended to improve cereal-based flour quality. This study was aimed to evaluate the effect of two fermentation methods namely solid state (a method adopting tempeh processing procedure with fermentation course of 60 and 72 h) and submerged fermentation (similar to ampok processing procedure with fermentation course of 72 and 84 h). The fermented-sorghum grains were then dried, and milled to produce sorghum flour. Analyses of proximate, physical poperties (particle size index/PSI, Water Absorption Index/WAI, swelling power) and amylograph profiles were carried out to obtain the flour characteristics. The results showed that both fermentation methods significantly influenced the proximate, physical and amilograph properties of the sorghum flour. Solid state fermentation of sorghum grains decreased the starch content, reduced its lightness, swelling power and viscosity, while increased the PSI and WAI. However, the solid state fermentation did not significantly change the protein, fat, ash and moisture content of the sorghum flour. Submerged fermentation of sorghum grain decreased the starch and protein content, increased the lightness, swelling power and viscosity, while did not significantly modify fat, ash and moisture content of the flour. Based on the characteristics obtained, it is suggested that sorghum flour made from solid state fermented-sorghum grain may be applicable for making–not viscous-food products, such as porridge. On the other side, the sorghum flour made from submerged-fermented-sorghum grain may be used as thickening agent, binder or for making highly viscous food products.

This study aimed to utilize saponins from papaya leaves as antifungal on maize husk packaging. Crude and semi-pure saponins were extracted from papaya leaves using Soxhlet and Ultrasonic-Assisted Extraction (UAE) methods. The total saponin contents were determined using UV-Vis spectrophotometry. Their ability to inhibit Aspergillus niger was tested by macrodillution method. The extracts were also applied to maize husk by soaking it for 5 minutes at concentration of 10, 20 and 25 mg/mL. The parameters observed were physical and mechanical properties (tensile strength and elongation), water vapor transmission rate (WVTR), total plate count (TPC) and mold and yeast counts (MYC) after 25 days of storage at room temperature (±28ºC). Drying of young papaya leaves using cabinet dryer resulted in the highest yield of crude saponin (12.96 ± 0.26%). Total saponin content in crude saponin extract was 115.43 mg/g, while in semi-pure saponin extract was 480.19 mg/g. Crude saponin and semi-pure saponin extract at concentration of 25 mg/mL could inhibit the growth of A. niger for 1.35 and 0.36 log CFU/mL, respectively after 24 hours. The WVTR test indicated that treatment with a concentration of 25 mg/mL of crude saponin extracts showed the lowest transmission. The addition of crude saponin and semi-pure saponin extract to the maize husk at the concentration of 10, 20 and 25 mg/mL was able to inhibit the microbial growth, represented by constant number in TPC and MYC for 25 days storage. This study showed that crude saponin and semi-pure saponin extract could improve the functional properties of maize husk as packaging materials.

The giant swamp taro starch or daluga corm starch in this study was extracted from corms collected from Siau Island of North Sulawesi Province in Indonesia. Native starch daluga corm has low resistant starch content, so starch modifications method were needed to increase its resistant starch content. The effect of acid hydrolisis, debranching, autoclaving-cooling and heat moisture treatment on the changes of RS3 daluga were studied. The corrm starch was first modified with acid hydrolysis (HA) and debranching with pullulanase (D). The starch was then modified with one cycle autoclaving-cooling (HADAC1x), HADAC1x with heat moisture treatment (HADAC1x+HMT), three cycle autoclaving-cooling (HADAC3x), HADAC3x with heat moisture treatment (HADAC3x+HMT) which increased its RS3 content to 42.37, 40.47, 31.12, and 31.18% (db), respectively. The starch modification method can affect other chemical properties changes such as starch content, amylose content, and reducing sugar content.

Eggs consumption in Indonesia increases every year resulting in egg shell waste. In addition, the functional components including ovotransferrin existing in this waste has not been yet studied well. This research has been done to explore ovotransferrin in egg shell membrane from local Indonesia and leghorn hens. The ion exchange chromatography using SP-Sepharose Fast Flow was used to purify the ovotransferrin from egg shell membrane. The fractions from salt elution were analyzed for protein concentration and protein profile using sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS - PAGE). The result showed that the best concentration of salt elution to obtain ovotransferrin was 0.1 mM NaCl since the single band was detected among other fractions. The ovotransferrin concentration (%) per single egg was also calculated as much as 0.75±0.017 and 0.16±0.005 for leghorn dan local Indonesia hen, respectively. This result may provide the beneficial information to purify ovotransferrin from egg shell membrane which conceivably as a food preservative agent.

Soft tofu dessert is a traditional food made from soft tofu and ginger drink. The traditional ginger drinkcontains antioxidant compounds. There are many varieties of ginger in Indonesia which have different antioxidant activities. Partially subtitution of Zingiber officinale var. Rubrum by Zingiber officinale var. Amarum was expected to improve sensory characteristics and antioxidant activity of traditional ginger drink. The objective of this research was to improve the formula of ginger drink based on sensory characteristics and antioxidant activity in the development of soft tofu dessert as a functional food. Optimization was done by Response Surface Methodology (RSM) based on the value of lightness (L) and °Hue of ginger drink which measured by Chromameter and antioxidant activity determined by DPPH method. Independent variables using in this optimization were the concentration of ginger and brown sugar. The optimal formula of ginger drink and its application in soft tofu dessert were analyzed by the hedonic rating method. The result of optimal formula consisted of 10.00% Zingiber officinale var. Rubrum, 9.99% Zingiber officinale var. Amarum, and 10.00% brown sugar with a desirability value of 0.822. The antioxidant activity of the optimal formula of ginger drink was AEAC 553.40 ppm, lightness (L) value was 40.03, and oHue was 74.67. The result of sensory test showed that the panelist preference for optimal formula was higher than for the traditional formula of ginger drink, while the acceptance level of the optimal formula was also higher than the tradisional formula of soft tofu dessert.

Microencapsulation techniques have been used to improve the stability of carotenoids and in the development of food fortification. The aim of this study was to determine the effect of the ratio of the coating material formulation (maltodextrin (MD) and soy protein isolate (SPI)) to the core material crude palm oil (CPO) on the physicochemical characteristics of the CPO microcapsules. Microencapsulation were carried out with ratios of coating material (MD:SPI = 2:1(w/w)) and CPO of 1:1.0, 1:1.2, 1:1.4, and 1:1.6 (w/w). The mixtures were homogenized at 12.000 rpm for 3 minutes and then spray dryed at inlet temperature of 180°C and outlet temperature at 80°C. The CPO microcapsules were analysed for yield, moisture content, solubility, and encapsulation efficiency. The results showed that the formulation ratio of 1:1.6 (w/w) was the best because it had the highest yield (20.12±0.02%), total carotenoids (295.2±0.32 µg/g) and encapsulation efficiency (59.95±1.50%). The best CPO microcapsules had spherical shape and smooth surface with an average size of microcapsules of 1-12 μm. The results of X-ray diffraction (XRD) showed that microcapsules were in crystalline state with crystallinity and amorphous value of 69.3 and 30.7%, respectively.

Anthocyanins are red to purple pigments and one of potent safe and natural food colorants which possess superior antioxidant activity. However, the stability of anthocyanins depends on various factors, including structure and concentrations, pH, temperatures, light, co-pigment, ascorbic acid, enzymes, metal ions, sugars, protein, sulfur dioxide. The aims of this research were to evaluate the effects of sugar addition on the stability of anthocyanin of black mulberry under different fluorescent light intensities and to determine the appropriate concentration of sugar that could increase black mulberry (Morus nigra L.) anthocyanin stability. Fluorescent lamp at 3370, 4210, and 8820 lux (18, 23, and 32 watt, respectively) were used to illuminate black mulberry fruit extract (10.09 g/L) following 20, 40, 60% (w/v) of sugar addition. Determination of anthocyanin color stability in extract of black mulberry fruit was perfomed using degradation kinetics modeling to obtain the appropriate order. The concentration rate (k) and half life (t1/2) were then calculated based on subsequent order. The results showed that 20% sugar addition enhance the stability of black mulberry anthocyanin extract as compared to that of control (without sugar addition) as indicated by half life increment from 170.826 to 183.733 h. On the other hand, anthocyanin stability decreased to 166.618 and 146.235 h half life with further sugar addition to 40 and 60%, respectively. Therefore, 20% sugar addition to black mulberry extract could improve its anthocyanin stability.
