 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.

Rumput laut merupakan sumber daya hayati yang sangat berlimpah di perairan Indonesia. Namun demikian pemanfaatannya untuk pengolahan produk pangan sangat terbatas, terutama untuk produk pangan fungsional. Rumput laut berpotensi dikembangkan sebagai produk pangan fungsional karena mengandung zat gizi dan komponen bioaktif yang berkhasiat untuk kesehatan. Rumput laut mengandung sejumlah komponen bioaktif seperti senyawa fenolik, pigmen alami, polisakarida sulfat, serat dan komponen bioaktif lainnya yang telah diteliti berkhasiat untuk kesehatan. Untuk dapat dikembangkan sebagai produk pangan fungsional, rumput laut yang digunakan harus bebas dari cemaran logam berat dan bahan pencemar lainnya, harus mengandung komponen bioaktif dan zat gizi yang tinggi sehingga harus ada penerapan standar penanaman dan penanganan pasca panen yang baik di tingkat petani rumput laut. Selain itu Proses pengolahan pangan yang diterapkan tidak merusak komponen bioaktif yang terkandung dalam rumput laut. Optimalisasi pengolahan rumput laut sebagai produk pangan fungsional merupakan alternative pemanfaatan potensi rumput laut Indonesia yang dapat meningkatkan nilai ekonomi rumput laut dan yang lebih penting dapat menyediaakan akses pangan sehat bagi masyarakat luas.Seaweed is a living resource that is abundantly available in Indonesian water. However, its utilization in food processing is very limited, especially as functional food products. Seaweed has the potential to be developed as functional food products because it has nutrient and bioactive components that are beneficial for health. Seaweed has a number of bioactive components such as phenolic compound, natural pigment, polysaccharide sulphate, fiber and other bioactive components that has been studied to be advantageous for health. For a seaweed to be developed into functional food product, it must be free from heavy metal and other pollutant contamination, and must contain bioactive components and high nutrients, thus, a good cultivation and postharvest handling standard have to be applied in seaweed farmer level. Moreover, the food processing applied should not damage the bioactive component within the seaweed. Optimization of seaweed processing into functional food product is an alternative for seaweed potential utilization in Indonesia, which could improve the economic value of the seaweed, and more importantly it could provide access for healthy food for community.

Rice-analogue (RA) made from sorghum (Sorghum bicolor L. Moench) has recently been popular in Indonesia for its potential as an alternative staple food besides rice. Sorghum has many phytochemicals with various functional properties including those which correlate to anticancer activity. The RA production in-volves several steps; polishing, milling, mixing, extruding, and oven drying. This study used FTIR based metabolomics to identify if these steps affect sorghum phytochemicals composition and its cytotoxicity acti-vity against HCT-116 cell lines in-vitro. It was discovered that sorghum cytotoxic activity was relatively sta-ble during the process. The RA final product (oven dried RA) showed higher activity (90.85%) as compared to other samples taken from previous step (2000 ppm dose). The correlation between FTIR profile and cytotoxic activity of RA was analyzed using one of the multivariate data analysis method namely orthogonal projection to the least square (OPLS). By comparing the OPLS data with FTIR data of compounds reported to be found in sorghum, it is shown that typical FTIR patterns for phenolic compounds particularly ferulic acids, p-coumaric acid, and procyanidins, as well as phytosterols, were highly correlated with RA?s cytotoxic activity. The signals were found to be dominant in the most active sample (oven dried RA). It can be concluded that sorghum phytochemicals responsible for its cytotoxic activity were not affected by processing steps, therefore RA is potential to be promoted as alternative func-tional staple food in Indonesia.

Moringa oleifera seed has the potential as a source of new food ingredients having high nutritional content, especially protein. The objective of this study was to evaluate the effect of fermentation toward biochemical composition and in vitro protein digestibility (IVPD) of Moringa seed flour. Fermentation was carried out by soaking the seeds at room temperature (30±2°C) for 24 and 48 h, either naturally (without starter addition) and with starter addition (i.e. commercial starter containing lactic acid bacteria/LAB). Unfermented and fermented seeds were processed into flour and their proximate composition, antitrypsin, tannin and IVPD were analyzed. The statistical methods used were ANOVA and Duncan's test at confi-dence level of 95%. The best treated flour was chosen using the De Garmo method and the amino acid profile was then analyzed. Protein digestibility-corrected amino acids (PDCAAS) were calculated to deter-mine the biological quality of proteins. The results showed that fermentation affected the changes in bio-chemical composition of the flour. Longer fermentation time could reduce the crude protein and antitrypsin content in both types of fermentation. On the other hand, there was an increase in tannin content during fermentation. The IVPD also increased by 75% at 48 h fermentation from the initial digestibility of raw seeds of 71%, thus increase in tannin content did not affect the IVPD. Natural fermentation of moringa seeds for 48-hour resulted in the best flour with IVPD and PDCAAS values of 75.33% and 0.18 (18.31%) respectively.

In Indonesia, the utilization of winged bean seeds as a food source is very limited. Currently there is inadequate information on the characteristics of the seeds, especially the chemical properties associated with its maturity. This research aimed to analyze the chemical properties of winged bean obtained from different harvesting time. Three different harvesting times were investigated, i.e. eight (K1), twelve (K2), and as six (6) weeks after the first flowering stage as a control. K1 and K2 were dried at 40°C (24 h) to mimic the conventional preparation of beans practiced in Indonesia, while K3 was unripe seeds commonly consumed fresh thus it is analyzed as fresh seeds. K1 and K2 have water content between 12.3-13.0% (wb), ash content 4.7-4.8% (db), lipid content 13.4-15.4% (db), protein content 38.9-40.7% (db), carbo-hydrate content 40.8-41.0% (db), total phenolic content 7.6 and 5.3 mg GAE/g (db), antioxidant activity (IC50) 558.3 and 511.1 µg/mL, starch content 25.6-29.1%, reducing sugar content 1.3-1.7 mg/g. Mean-while, the unripe winged bean seeds (K3) has water content of 75.5% (wb), ash content 5.0% (db), protein content 19.6% (db), carbohydrate content 68.4% (db), total phenolic content of 59.4 mg GAE/g (db), anti-oxidant activity (IC50) 485.6 µg/mL, starch content 7.2% and reducing sugar 5.4 mg/g. Based on these che-mical properties and time efficiency, harvesting winged bean at 8 weeks (K1) was sufficient to produce winged bean potential as protein source, as well as a potential functional foods with good antioxidant acti-vity, total phenolic content, low starch and reducing sugar.

Some of Lactobacillus species isolated from breast milk are known to have antimicrobial activities, including against Escherichia coli. The aims of this study were to evaluate the antimicrobial activity of Lactobacillus species isolated from breast milk against enteropathogenic Escherichia coli strain K1.1 and the effectiveness of the Lactobacillus isolates to prevent diarrhea on rats (Sprague Dawley). The infective dose of E. coli K1.1 to induce diarrhea without causing death were also determined. Based on the antimicrobial activity there were three isolates of Lactobacillus that exhibited good inhibition againts E. coli K1.1, i.e. Lactobacillus rhamnosus R14, L. rhamnosus R23, and L. rhamnosus B16. Determination of E. coli infective dose showed that 108 CFU of E. coli K1.1 was sufficient to induce diarrhea on rat without causing death. The number of diarrhea rats and severity level in group treated with L. rhamnosus were lower than groups untreated with the Lactobacilli. This study showed that the three L. rhamnosus isolated from breast milk were able to prevent diarrhea due to infection of E. coli K1.1 when the Lactobacillus was regularly introduced prior to infection. L. rhamnosus R23 showed the best capabilities of preventing diarrhea in rats as compared to two other isolates of Lactobacillus. The incidence of diarrhea correlated with the number of lactobacilli in the feces. However when the period of diarrhea ceased, there were no difference in total lactobacilli and E. coli in the caecum, colon and feces between rats treated with L. rhamnosus and the control. This finding revealed the L. rhamnosus isolated from breast milk were potential for prevention of diarrhea when consumed regularly.

Kekurangan Vitamin A (KVA) di Indonesia masih merupakan masalah utama. Kekurangan vitamin A tingkat berat (rabun senja) telah jarang ditemui, tetapi tingkat KVA subklinis masih bisa ditemukan. Minyak sawit mentah (CPO) memiliki kandungan tinggi karotenoid sebagai sumber provitamin A. CPO secara alami berwarna merah karena mengandung karotenoid yang tinggi, dan belum dimanfaatkan di Indonesia. CPO mengandung karotenoid dan vitamin E yang berfungsi sebagai antioksidan bagi tubuh. Antioksidan dapat mengurangi kerusakan sel dengan menetralisir radikal bebas serta mencegah kerusakan lipid, protein, enzim, dan DNA. Tujuh puluh responden dipilih untuk konsumsi CPO selama 2 bulan dengan dosis ± 3.27 ml/hari. Plasma darah dari 22 responden yang sehat dianalisis dengan metode asam Tri Fluoro asetat (TFA), enzim aspartat Transaminase (AST), Alanine transaminase (ALT), Alkaline Phospatase (ALP) kit. Hasil penelitian menunjukkan 16 responden mengalami peningkatan jumlah retinol plasma dan penurunan tingkat aktivitas AST, ALT, dan enzim ALP. Penelitian ini menunjukkan bahwa CPO memiliki aktivitas antioksidan yang dapat meningkatkan kesehatan hati, sehingga dapat menjadi alternatif sumber provitamin A untuk menangani kekurangan vitamin A di Indonesia
