Diabetes is the most common endocrinal disorder characterized by hyperglycemia and long term complications. It has been reported that oxidative stress and excess of free radicals play major roles in diabetes. Development of antidiabetic drugs has been recently emphasized on natural products with less side effect. Antidiabetic activities of white saffron (Curcuma mangga) have been reported. In this study, antiadiabetic activity of four fractions of C. mangga extract (water, hexane, ethyl acetate, buthanol), white saffron extract and butylated hydroxytoluene/antioxidant standart) was measured by α-amylase activity assay, while antioxidant activity of those fractions was measured using 2-diphenyl-1-picrylhydrazyl scavanger, and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) assay. These fractions were also compared to antidiabetic drug, acarbose, as control. Ethyl acetate fraction and white saffron extract showed higher α-amylase inhibitory activity (IC50 = 840,23 dan 363,67 µg/mL) among fractions. Ethyl acetate fraction of C. mangga showed the higher antioxidant activities among fractions as indicated by DPPH activity DPPH (IC50 = 83,95 μg/ mL), and ABTS (IC50 = 27,37 μg/ mL).

Maize noodles processing is different from that of conventional noodles made of wheat flour. In pro-ducing non wheat (gluten free) noodles, engineering is needed in the manufacturing process to obtain noodles with good quality and similar to the physical quality of wheat noodles. Processing of maize noodles requires particular treatment, such as heating, shearing, and maize noodles processing with sheeting techniques had previously been reported. Maize noodles processing using extrusion technology has also been done, but in previous studies, the maize used was of the hybrid varieties. This study aims to identify the pasting properties of maize flour and optimize the processing of dried maize noodles from local variety obtained from Madura Island named Elos. Extrusion technology was used to produce maize noodles with good physical characteristics. This study used a cooking-forming single screw extruder and formula consisting of 100% maize flour (db), 70% moisture content, and 2% NaCl. The experimental design was a complete randomized factorial design with two process variables, i.e. extruder temperature setting (75, 90, and 105°C) and extruder screw speed setting (100, 130, and 160 rpm). Response surface methodology (RSM) was used for process optimization to obtain the best process conditions based on several physical characteristics as the responses, i.e. cooking loss, elongation, hardness and degree of gelatinization. The optimum process conditions resulted from the Design Expert 7.0 program were extruder temperature of 95°C and screw speed of 100 rpm. The optimum condition produced maize noodles with cooking loss of 10.11%, elongation of 156.73%, hardness of 6252 gf and degree of gelatinization of 92.26%, with a desirability value of 0.954.

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.

Fruit jam added with probiotics is an innovation in food product development. In this research, pineapple jam was made not only to increase the economic value of the pineapple but also to add the health properties due to the addition of probiotics (Lactobacillus acidophilus). The objective of the study was to evaluate the stability of L. acidophilus microcapsules ATCC 314 against heating and storage in low sugar pineapple jam. L. acidophilus was microencapsulated with emulsification method using sodium alginate and oil with Tween 80 as the emulsifier. The microcapsules size was 40-60 µm. Microencapsula-tion was found to improve the stability of L. acidophilus upon heat processing. Total healthy cells of the microencapsulated probiotics heated at 40 and 50°C (1.4x107 CFU/mL; 6.9x106 CFU/mL) were higher than the free probiotic cells (7.9x106 CFU/mL; 4.5x106 CFU/mL). The stability of the encapsulated probiotics in pineapple jam at 4°C (14 days of storage) was also better than that of the free cells. Conclusively, micro-encapsulation process with alginate could increase probiotic stability, thus can be considered in probiotic pineapple jam development.

Lemongrass (Cymbopogon citratus (DC.) Stapf, Poaceae) has been known for demonstrating anti-microbial activity against food spoilage bacteria. These antimicrobial properties can be further utilized for the development of natural food preservatives. In this study, the compounds present in water extract and essential oil of lemongrass were analyzed and their potential as tofu preservatives was evaluated. The water extract was prepared by the infusion method, while the essential oil was made by steam and water distillation. The phyto-chemicals composition of the water extract and essential oil was analyzed by qualitative colorimetric phyto-chemical screening and Gas Chromatography-Mass Spectroscopy (GC-MS) technique, respectively. Their preservative activity on tofu was evaluated by observing their ability to inhibit the growth of bacteria on the tofu and the physical changes of tofu during 10 days of preservation at room temperature. The results showed that lemongrass water extract contained terpenoids, tannins, and saponins. The GC-MS analysis identified 13 compounds in the essential oil. Neral, geranial, β-myrcene, juniper camphor, and viridiflorol were found as the major compounds. At concentration of 20%, lemongrass water extract demonstrated inhibition of bacterial growth during 10 day storage of tofu and improved the shelf life by 4 days longer from those of the negative control. In contrast, lemongrass essential oil did not show inhibitory activity in bacterial growth in tofu but it was capable of maintaining the color, odor, and texture of tofu as well as delaying the slime formation up to 4 days.

Tea is one of the most widely consumed beverages in the world. Different types of tea provide different sensory profiles. The present study aimed to evaluate sensory characteristics of green tea by analytical sensory evaluations through QDA (Quantitative Descriptive Analysis) and CATA (Check-All-That-Apply) methods. The sensory characteristics of green tea from three different countries (China, Thailand and Indonesia) were evaluated using QDA by trained panels and CATA by consumer panels. The QDA method revealed sensory characteristics of green tea, while CATA method presented information on consumer preferences towards the most desirable characteristics of green tea. The results showed that green tea has dominant characteristics of bitter taste, astringent aftertaste, green flavor, fermented flavor and dry aroma. Moreover, floral aroma and flavor in green tea have considerable influences on the panelist preferences. However, “nice to have” attribute was not found in the penalty analysis. The “must have” attribute in green tea was floral aroma, while the “must not have” attributes were burned aroma, burned flavor and dry aroma.

Germination constitutes one of bio-processing techniques and has attracted a tremendous attention due to its advantageous effects on the improvement of technical functional properties of grains. Mean-while, blanching has been used as the complementary treatment in germination. The aim of this study was to evaluate the changes in the functional properties of Moringa oleifera seed flour due to germination and blanching that affect the characteristics of the resulting food the products. Germination was performed at four levels of incubation time (0, 48, 72, and 96 hours) at room temperature in the dark room and two levels of blanching time (0 and 30 second). The functional properties analyzed consisted of bulk density, flour solubility, water and oil absorption, and capacity and stability of emulsion. The results of this study showed that germinated Moringa seed flour had significantly better technical functional characteristics than the ungerminated ones, i.e. bulk density (0.33-0.43 g/mL), flour solubility (16.82-21.00 g/g), water absorp-tion capacity (0.93-0.99 g water/g), oil absorption capacity (1.18-1.58 mL oil/g), and emulsion capacity (88.80-91.70%). Blanching decreased the functional properties of the flour. The statistical analysis showed that there was no significant interaction between two factors in all parameters. This study shows that ger-mination is a good method to improve the functional properties of Moringa seed flour, but blanching dec-reases them. Germination without blanching is recommended to improve the technical functional charac-teristics of the flour.

Tea beverages are getting more popular in Indonesian market. Today, consumers can find tea beverage products in many variants, including ready to drink (RTD) tea beverages. One of the most important ingredient in tea beverages is sugar that provides sweet taste. Due to the increasing concerns on the risk of diabetes mellitus type 2, the Indonesian government has campaigned to reduce sugar consumption. This research purposes were to understand and analyze the type of sweeteners in RTD tea beverages and the producer strategy in reducing sugar. The study was conducted by collecting available RTD tea beverages in modern retail shops. All ingredients on the label was recorded then the correlation with other information on the label and regulation was analyzed. The results showed that all of the sweetened RTD tea beverages (n=58) use sucrose as the sweetener. Sucrose was used singly (81%) or in combination (17%) with other sweeteners. Most RTD tea beverages (60%) used sucralose in combination with sucrose. Others used steviol glycoside (20%) and fructose (20%). There were 24% of the RTD tea beverages that provides claim, 64% of the claim was regarding sugar and calorie. Based on the correlation analysis, it was concluded the tea beverage producers use three strategy in reducing calorie and sugar content in their products, i.e. by 1) totally removing the sugar content, 2) reducing the sweetness level, or 3) combining sucrose with high intense sweetener.
