SENSORY PROFILE OF 3 IN 1 INSTANT COFFEE USING EMOTIONAL-SENSORY MAPPING, FLASH PROFILE, AND CATA (CHECK-ALL-THAT-APPLY) METHODS
Get PDFThree in one instant coffee is popular among university students. A variety brands of such instant coffee are available on the market. However, the literature on the sensory aspects of the instant coffee is rather limited slim. The project aimed to test three-in-one instant coffee sachets for their sensory characteristics. Two methods, CATA (Attributes and Emotional Mapping) and Flash Profile (extension of Free Choice Profiling) were employed to generate the attribute profiles and emotional dashboard. Sixty IPB University students were selected as panelists. Sensory attributes terminologies and their relation to emotion were generated using Focus Group Discussion among instant coffee heavy drinker. Profile of coffee D showed a creamy texture, while sweetness and milky was dominant when it came to coffee B and coffee C. The creaminess in coffee G was strongly related to feelings of happiness in a consumer. In addition, the sweet and milky taste and flavor in coffee B was seen as a relaxing and luxurious feeling. A Preference Mapping was constructed, and it showed that sweetness, milky, and creaminess improved the liking of the student consumers that make coffee C the most preferred brand among the panelists. In short, the use of flash profiles and check-all-it-dilute/CATA (attributes and emotional) equipped with preference mapping can provide emotional attributes and dashboards that will be important to understand products more than just consumer liking
Potensi Probiotik Bakteri Asam Laktat Asal Madu dari Tiga Jenis Lebah yang Berbeda
Get PDFCertain strains of Lactic acid bacteria (LAB) especially from the genus of Lactobacillus and Bifidobacteria have been recognized to have health beneficial effect as probiotics. Honey has been known to have health beneficial effects and contains lactic acid bacteria. However, information pertaining the characteristics of LAB from honey is still limited. The present research aimed to isolate LAB from different types of honey and to evaluate their potency as probiotic. The LAB were enumerated and isolated from honey produced by three different honeybees: Apis cerana, Heterotrigona itama, and Trigona laeviceps. The results showed the count of LAB in three different honey ranged from 5.0x101 to 2.3x107 CFU/mL and affected by different time of sampling. The highest of average LAB count was found in honey of Heterotrigona itama. There were 48 Gram positive catalase-negative bacterial isolates obtained from the three different honey types. Twelve isolates were selected based on their survival in bile salt. The twelve selected isolates were capable of growing in MRSB pH 2.5, and MRSB containing 0.3% bile salt. They also exhibited strong antibacterial activity against pathogenic bacteria. Identification based on 16S rRNA revealed that of the twelve isolates, nine were identified as Lactiplantibacillus plantarum and three others as Pediococcus acidilactici. The twelve isolates showed high survival at low pH dan bile salt and exhibited antimicrobial activity against pathogen, hence they are considered as probiotic candidates
PENGARUH PEMBERIAN JUS BIT TERFORTIFIKASI FESO4 INSTAN (JUS BEEFE) DALAM MENANGGULANGI ANEMIA ATLET REMAJA PUTRI
Get PDFProlonged physical exercise has the risk of increasing free radicals which will affect the breakdown of red blood cells and promote the risk of decreased hemoglobin. Adolescent female athletes have a risk of decreasing hemoglobin due to menstruation. This situation can get worse if the athletes have iron defi-ciency or anemia as the result of poor diet choice. Increased radicals and anemia affect the amount of oxygen carried to the tissues and the maximum volume of oxygen an individual can use to produce energy (VO2 max). Beets have benefits for athlete\u27s performance and have been developed into an instant drink. The purpose of this study was to determine the effect of an instant FeSO4 fortified beet juice (BeeFe juice) in overcoming anemia on female adolescent athletes. This research using an experimental study with controlled trial pre-posttest design. Twenty-nine adolescent female athletes, aged 13-19 years, were divided into two groups. Fe tablet supplementation (containing Fe 60 mg) was given to 15 athletes in the control group and BeeFe juice (containing Fe 17 mg) was given to 14 athletes in the treatment group du-ring the luteal and menstruation phase (±14 days). Hemoglobin levels, Malondialdehyde (MDA) and maxi-mal oxygen volume (VO2 max) were examined before and after the intervention. Data were analyzed using paired t-test and independent t-test IBM SPSS version 22. This research has obtained Ethical Appro-val with number KE/FK/0633/EC/2018 from the Ethical Commission of FKKMK UGM. The results showed no significant difference between the group given Fe tablets and the group given BeeFe juice on hemo-globin levels (P>0.05), MDA levels (P>0.05), and VO2 max levels (P>0.05) in the menstrual and luteal phases of menstruation. It can be concluded that BeeFe juice has the same effectiveness as commercial Fe tablets. BeeFe juice can be an alternative food ingredient in iron supplementation
Differentiation of beef, buffalo, pork, and wild boar meats using colorimetric and digital image analysis coupled with multivariate data analysis
Get PDFBeef price is relatively expensive, which makes this commodity vulnerable to be counterfeited. The development of rapid, cheap and robust analytical methods for meats authentication has therefore become increasingly important. In this study, colorimetric and digital image analysis methods were used to characterize and classify four types of meat (beef, buffalo, pork, wild boar) and two muscle types from each sample (Semitendinosus and Vastus lateralis). Multivariate data analysis (PCA and OPLS-DA) was used to observe classification pattern among species using different color parameters data obtained from meat chromameter and digital image measurement. The results showed that PCA and OPLS-DA successfully classified meat from different species and different muscle type based on color, both in chromameter and in image analysis. It was shown that pork had the highest lightness level, and was the most different among the four types of meat tested. Beef was predominated by yellowish color, while buffalo meat had the highest reddish color level. Semitendinosus and Vastus lateralis muscles had different color intensity where Vastus lateralis exhibited darker color intensity. This study showed that meat color analysis using chromameter and imaging techniques can be used as cheap and quick tools to discriminate meats form different species and different muscles type
Optimasi Formula Tepung Komposit Tinggi Protein dan Seng dengan Response Surface Methodology
Get PDFCovid-19 pandemic had limited people’s movement despite the demand to remain productive and maintain good health. Therefore, it was necessary to provide foods which are easy to distribute, durable, nutritious, and easily transformable to increase immunity. This research aims to develop a composite flour (TK) formula with optimal proportion of wheat flour (TT), snakehead fish flour (TIG), pumpkin flour (TBuL), and pumpkin seed flour (TBiL) which then enriched with zinc. The resulting TK is expected to be used as an ingredient for nutritious snacks containing high protein and zinc. The research was conducted in four stages, namely the making of each constituent flour, determining the best formulation with the Response Surface Methodology using Central Composite Design model, characterizing the physicochemical properties of TK and making meatballs, biscuits, and unting-unting from the TK. The three products were tested on experimental animals for their metabolic responses. The optimization of the formula resulted in three optimal formulations, namely formula A, B, and C with the proportion of TT:TIG:TBuL:TBiL respectively as follows 55:20:15:10; 56.65:20:13.35:10; 57.98:20:12.02:10. The most optimal formula of composite flour was formula A with the highest protein (26.12%) and zinc (18.06 mg/kg) content among other formulas. Then, zinc was added into Formula A using microencapsulation, and TK with protein content of 26.74% and zinc of 56.8 mg/kg were obtained. The histopatology observation on experimental animals showed that the three products made from TK did not cause necrosis of the liver or cell infiltration in the kidneys
Low Fat Premixed Mayonnaise Block Used OSA-Corn Starch as Egg Yolk Replacer Plus Corn Starch Binding Agent
Get PDFMayonnaise contains a substantial amount of fat and water. Therefore, it is easily degraded during storage. Reducing fat and moisture content in mayonnaise could extend its shelf life. It can be done by replacing the egg yolk to octenyl succinic anhydride (OSA)-corn starch and then forming it as a premixed block using a binding agent. The research objective was to obtain technology for low-fat mayonnaise making by OSA-cornstarch and corn starch addition but still acceptable by consumers based on its physicochemical and sensory characteristics. The low fat premixed mayonnaise was made by mixing the egg yolks and/or OSA-corn starch, corn starch, mustard, sugar, salt, and xanthan gum. A completely randomized research design was used with three levels of OSA-corn starch (0, 25, and 50%) to replace egg yolk and its combination with corn starch as a binder agent at 43 and 50%. The parameters analyzed on the premixed mayonnaise blocks included moisture and fat content, water absorption index, and water solubility. In contrast, parameters for constituted mayonnaise were moisture content, viscosity, and hedonic sensory analysis by 25 semi-trained panelists. The constituting step of the mayonnaise was the further addition of water, oil, and lime juice before serving. The data were analyzed with ANOVA. The results showed that OSA-corn starch and corn starch addition could reduce the fat content of premixed mayonnaise by 41.7% which was obtained from 50% OSA-corn starch and addition of 43% corn starch. The resulted mayonnaise was slightly liked by the semi-trained panelists (scored 3)
Karakterisasi Aktivitas Fungsional Senyawa Bioaktif dari Whey Hasil Samping Produksi Tahu
Get PDFTofu whey is a by-product obtained during tofu production that contains proteins and peptides, soluble carbohydrates, soy isoflavone, and minerals. This research aimed to characterize the functional properties of whey protein from tofu through separation using membranes with different pore sizes. The permeate resulted from Whatman No. 3 filtration was subjected to acidity (pH) and protein content measurement, while its protein profile was characterized by SDS-PAGE. electrophoresis. Additionally, this permeate was further sieved using ultrafiltration membranes with 30, 10, and 5 kDa cut-off. The corresponding filtrates were analyzed for antioxidant activity, isoflavone content, and ACE inhibitor activity. The tofu whey had a pH of 3.14, crude protein of 2 g/100 g sample, and soluble protein content of 1.47mg/mL. The separation of protein bands using SDS-PAGE showed that the dominant protein or peptides in tofu whey had molecular weights below 18 kDa. The use of ultrafiltration membranes could increase the bioactivity of permeates. The filtrate resulting from the smallest membrane cut-off (i.e., 5 kDa) had a higher antioxidant activity, isoflavone content, and ACE inhibitory activity
