Abstract

Banana (Musa spp.) is mainly grown in the tropical and subtropical countries. Previous study reported that Musa spp. leaves had a potential antioxidant activity, but it was still rarely studied further. In this research, leaves of Musa balbisiana, Musa acuminate, and Musa paradisiaca were extracted using maceration method for 24 hours with three kinds of solvent having different polarities: ethanol (polar), ethyl acetate (semi polar), and hexane (nonpolar). The goal of this research was to compare and determine the stability of the antioxidant activity extracted from different Musa sp. leaves. The highest antioxidant activity is found from Musa balbisiana leaves extract with IC50 value 340.07±22.54 ppm (hexane fraction). Correlation analysis between antioxidant activity, total phenolic content, and total flavonoid of the extracts cannot conclude that the active antioxidant substances in these three banana species leaves were from phenolic or flavonoid groups. This crude extract from Musa balbisiana was then subjected to various pH levels (3.0, 5.0, 7.0, and 9.0) and temperatures (50, 70, and 90°C) to determine the stability of its antioxidant activity. It is found that the best stability condition is at pH 3.0 and temperature of 50°C with an increase of 63.1% in IC50, a decrease of 15.72% in total phenolics, and a decrease of 3.67% in total flavonoids as compared to before treatment.

Abstract

The development of functional foods requires extensive research and development (R&D) activities for product development, technology development and commercialization. However, it becomes rather a complex issue in developing countries, including Indonesia. This study briefly discusses the status of functional foods R&D in Indonesia by understanding the opportunities and challenges. Employing scientometrics with bibliometric data from Scopus Database from the early retrievable date to October 29, 2018, the study finds out that R&D on functional foods in Indonesia indicates a substantially increasing trend in the last decade. The research activities are mostly conducted by public research institutes (PRIs) and universities in the area of identification of bioactive compounds and their effects on health. They explore the abundant potentially indigenous biodiversity from Indonesia, both land and marine resources. Nonetheless, the R&D activities are still lacking of network and integration between the subject areas. Underdeveloped infrastructure, limited human resources and financial support, costly preparation for the clinical test to satisfy health claims regulation and the gap between academic research and industry have been key issues in Indonesian functional foods R&D. By using innovation system perspectives, this study suggests that public R&D on functional foods demands active collaboration between PRIs, universities and industry as well as the supportive regulation system from policymakers to enhance the development of functional foods in the future.

Abstract

Sardinella (lemuru) is a genus of fish that is widespread in the East Java Sea region, especially in Muncar, Banyuwangi in East Java Province, Indonesia. Marine fishes are rich in essential fatty acids, including omega-3. This study aims to improve the quality of lemuru fish oil through the use of adsorbent materials such as bentonite and activated carbon. The sample was analyzed to determine its free fatty acid (FFA) content and peroxide value (PV) using the titrimetric method. The clarity of the oil was determined using the spectrophotometric method (λ 440 nm). The omega 3 content from the fish oil sample was then enriched through enzymatic reactions using lipase. Enzymatic reactions were carried out for 5, 10, 15, 20, 35, and 47 hours with a lipase concentration of 500, 1000, 1500, and 2000 units respectively. The omega-3 content of the fish oil products was analyzed using the GC-FID method. The results show that the addition of 3% activated carbon and bentonite in the fish oil reduced the FFA and PV results. Moreover, the absorbance value at λ 440 nm was also reduced from 0.883 to 0.559. The highest content of omega-3 was obtained through hydrolysis with lipase at a concentration of 1000 units for 35 hours with alpha-methyl linolenate (ALA), methyl all-cis-5,8,11,14,17-eicosapentanoate (EPA) and cis-4,7,10,13,16,19-docosa-hexaenoic acid methyl ester (DHA) at 0.78, 1.06, and 0.29% respectively.

Abstract

Weaning food biscuit based on mocaf (modified cassava flour) with substitution of soybean, mung bean and red kidney bean flour is expected increasing protein of the product. However, in the legumes flour there are anti-nutritional agent that can affect the absorption of other nutrient such as protein and iron. The purpose of this study was to evaluate the absorption of protein and iron from mocaf based-weaning food. Protein and iron absorption were determined from weaning food (biscuit) using Sprague-Dawley rats, 3 weeks old, weight 70-80 g for 0, 30, 60, 90, and 120 minutes. The treatments of this study were mocaf biscuits (as a control), biscuits with substitution of soybean flour (MSF), mung bean flour (MMF), red kidney bean flour (MRF) and commercial biscuits (CB). The highest protein absorption of control, MSF and MRF were at 120 minutes with absorption percentages 27.76, 38.94, and 9.35%, respectively. Samples MMF and CB had the highest protein absorption at 60 and 90 minutes, with absorption percentages 15.58 and 37.57%. Meanwhile, the highest iron absorption of control, MSF and MMF were at 90 minutes with absorption percentages 53.86, 4.71, and 54.29%. Samples MRF and CB had highest iron absorption at 60 minutes with absorption percentages 7.97 and 69.76%, respectively. The MSF sample had highest protein absorption than other samples. Meanwhile, the MMF sample had an iron absorption value that approached to commercial biscuit.

Abstract

Mangoes of Gedong variety (Mangifera indica L. var. gedong) is one of the exported commodities from Indonesia. Half mature mangoes of this type are called gedong mangoes, whereas the full ripe mangoes are called gedong gincu mango. This research aimed to determine the physicochemical charac-teristics, sensory attributes and volatile compounds of the above two mango types. The results showed that gedong mangoes had a lower pH value, less total soluble solid, harder texture, and the skin color had a lower intensity of lightness, redness, and yellowness as compared to gedong gincu mango. The sensory analysis using rate-all-that-apply (RATA) method showed that attributes of color, fibrous, aroma (fruity, caramel, cooked, green, fermented, floral, sweet), taste (sweet, sour), melting, firmness, juiciness and astringency were significantly different between gedong and gedong gincu mango. The overall sensory of gedong gincu mangoes was more preferred by the panelists with the hedonic score of 6.20±0.09 (6= like) while that of gedong mango was 5.37±0.09 (5= slightly like). The sensory profiles of both mangoes were supported by the analysis of their volatile compounds. The gedong mango had predominantly green type of volatiles aroma while the gedong gincu was dominated by the fruity sweet ones. The sensory acceptability of gedong gincu mango was significantly higher rather than that of gedong mango.

Abstract

Previous study successfully conducted encapsulation of the purple-fleshed sweet potato’s anthocyanin but the study has yet to reveal the stability of encapsulated anthocyanin. Therefore, this research aims to observe the stability of encapsulated anthocyanin regarding the characteristic of low anthocyanin stability, which depends on environmental factors, such as temperature, pH, humidity, and water activity. The kinetic parameters of stability, including kinetic constant (k), reaction order, and half-life (t1/2), were also studied. Stability testing was conducted in high water activity of 0.75 and various in-cubation temperatures at 16, 25, 35, and 45°C. Un-encapsulated anthocyanin extract was also tested for its stability in the same condition in order to be compared with encapsulated anthocyanin. This study re-vealed that the encapsulated anthocyanin had lower stability than un-encapsulated anthocyanin extract. It was proven by higher kinetic constant and lower half-life of encapsulated anthocyanin for every incubation temperature which was induced by higher pH of encapsulated anthocyanin compared with anthocyanin extract. Besides, high water activity reduced glass transition temperature (Tg), in which encapsulated anthocyanin was in rubbery state. Both encapsulated anthocyanin and anthocyanin extract were degraded following the first order kinetic. Using the Arrhenius equation, it was obtained that the degradation kinetic constant of encapsulated anthocyanin was stated as k= 420.44 exp (-23.33/RT). Meanwhile, k= 1.12x106 exp (-46.70/RT) described degradation of kinetic constant of anthocyanin extract. The stability test re-vealed that the application of encapsulated anthocyanin was not suitable for wet-type food product.

Abstract

This research aims to study and characterize the effect of the annealing conditions (temperature and heating duration) on the gelatinization profile and antioxidant components of annealing-modified black glutinous rice flour (ABGRF). This experiment used a 2x3 factorial design consisted of temperature factor (54 and 58°C) and heating duration factor (4, 5, and 6 hours) with 2 replications. Research results showed that both factors and their interactions significantly affected all parameters of the gelatinization profile and antioxidant component of ABGRF (except through viscosity). Compared to its native, ABGRF showed an increase in peak viscosity, through viscosity (except treatment 54°C:5 hours), peak time and pasting tem-perature, indicated ABGRF resistance improvement to the heating process. Generally, the temperature treatment increment increased breakdown, setback, and final viscosity, but the heating duration increment decreased those values. The variation of ABGRF gelatinization profiles increased the diversification potential of BGRF-based food products. Annealing caused an overall decrease in ABGRF antioxidant ability. ABGRF produced by 54°C:4 hours treatment had the highest amount of antioxidant components (total anthocyanins contents 103.78±2.24 mg C3GE/100 g, total phenolic compounds 241.65±1.98 mg GAE/100 g, DPPH 267.14± 3.23 mg AAE/100 g, FRAP 473.94±1.43 mg AAE/100 g), thus using it as ingredients in functional food is more recommended, especially as composite flour for bread and cake.

Abstract

Color is one of quality parameters that affects consumer intention to purchase ready to drink (RTD) green tea. Consumers expect RTD green tea to have yellow greenish color, however the color becomes brown and darker during the shelf life. This study aimed to evaluate the effect of phosphate mix addition to water prior to green tea leaves extraction on pH, color, and the tannin in tea extract, pre-RTD, and RTD during incubation period at 60°C for 2 days. The pre-RTD contained tea extract, sugar, and ascorbic acid. Addition of sodium bicarbonate was done in pre-RTD to obtain RTD with pH of 6.1±0.2. The type of phos-phate used was sodium acid pyrophosphate (SAPP) and phosphoric acid. The concentrations of SAPP were 650 and 1300 mg/L, while those of phosphoric acid were 125, 250, and 500 mg/L.The total phospho-rous added from the combination of SAPP and phosphoric acid was 221-521 mg/L. Meanwhile, green tea extracted without phosphate was used as a control. The results showed that phosphate addition to water prior to green tea extraction caused decrease in pH of tea extract from 5.83±0.18 to 2.8-3.8, decrease in browning intensity, and reduced tannin degradation during the incubation period. Sugar and ascorbic acid added to the tea extract resulted in pH in all samples <4.0 and maintained the lightness of the pre-RTD. Phosphate application was not able to retain the color of RTD after incubation period. This study showed that addition of phosphorous as a combination of SAPP and phosphoric acid to water at concentrations of 221-521 mg/L prior to green tea extraction had positive impact in reducing browning intensity of RTD green tea with pH of lower than 4.0.

Abstract

Several grains (green bean, red bean, soybean, corn, nuts, sesame, and millets) were processed to yield a high protein analogue rice. Red beans and green beans were soaked in water for six hours while soybean was boiled for 10 minutes and then peeled. Nuts were dried at 70°C, ground, and sieved to pass 80 mesh. All grains were ground into powder except for sesame which was in whole seed. Four formulas of rice analogues were produced at a different level of millet (0-15%), corn (35-50%) with fixed level of red beans (10%), soybeans (25%), green beans (10%), sesame (3%), and glycerol monostearate (GMS) (2%). The products were analyzed in terms of proximate composition, hardness, water absorption index, development ratio, cooking time, in vitro protein digestibility, amino acids composition, and protein digestibility-corrected amino acid score (PDCAAS). The four analogue rice formulas contained high level of protein and protein digestibility, but they did not fulfill the targeted complementation. The protein content of the analogue rice varied from 18.19 to 19.09% (wet based) with protein digestibility of 81.27-88.86%. The most preferred formulas of the rice analogue was composed of corn (40%), millet (10%, red beans (10%), soybeans (25%), green beans (10%), sesame (3%), and GMS (2%). It contained 42.48% of amino acids score and 36.53% of PDCAAS value.

Abstract

Kappaphycus striatum and Kappaphycus alvarezii are kappa carrageenan-producing seaweeds. K. striatum is also a source of iota carrageenan. The study was aimed to evaluate the effects of extraction time and alkali concentration on the characteristics of semi refined carrageenan (SRC) produced from seaweeds K. striatum and K. alvarezii. The SRC was extracted prepared by cooking dried seaweed samples in KOH solution (ratio seaweed:KOH solution= 1:40) with KOH concentrations of 6, 8 and 10% for 60 and 120 minutes at 70°C. The results showed that the best SRC characteristics produced from K. striatum seaweed were obtained from the extraction process at 6% KOH for 60 minutes which yielded 46.05±0.16%, carrageenan with gel strength of 362,07±21,44 g/cm2 and viscosity at 70°C 74 cP. Meanwhile the best characteristics of SRC produced from K. alvarezii seaweed were obtained from extraction in 10% KOH for 60 minutes having the highest yield of 39,03±0.95%, gel strength 1130.67± 16.34 g/cm2 and viscosity at 70°C of 59 cP. FTIR analysis showed that the functional groups which are kappa carrageenan and iota carrageenan characteristics were found in both samples at wave numbers of 846.97-847.09 and 800.53-801.29 cm-1, respectively.
