Abstract

The mechanism of the drying process is the process of heat transfer and mass transfer that takes place simultaneously. The pressure of the water vapor in the acid gelugur is higher than that on the surface interface of the gums and air acids. Intensity solar radiation averages around 300-590w / m2 and Ambient Temperature 28,830C. The hot air condition in the drying box averages 320C. The content of total citric acid gelugur acid was 1.2787% with 3mm slice thickness and 1.3981% with a 5mm slice thickness. Drying is done from 08.00-17.00 am with a hot air flow rate of 1.5m/s.

Abstract

The attractive colors and colors derived from natural pigments are very much favored by consumers, as natural pigments in addition to being dyes also serve as a source of vitamins. The aims of this  study were to determine the effect of the amount of nanoemulsion applied  and storage duration on the color of wet banana noodles and the potential of wet noodles as a source of carotenoids and to increase the level of consumer acceptance of the color of wet noodles. The research used complete Random Design (RAL) factorial where first factor was the amount of nanoemulsion consisted of 3 levels namely: 0%, 3% and 6%. Second factor was storage duration consists of 3 levels :0 days, 3 days, and 6 days. Each treatment with three replications. The results showed that the color of wet noodles ranged from yellowish to yellow. The intensity of the yellow color decreased during the storage process. The 3% nanoemulsion applied on wet noodles potentially suffice 4.4% of the vitamin A requirement  and its potency decreased to 2.6% after the noodles were stored for 6 days. While noodles applied 9% nanoemulsion on noodle was potentialto suffici vitamin A by 10,4% from requirement of vitamin A, but decrease to 4.3% after wet noodles were kept for 6 days. The storage duration gave no significant effect on the color preference test but the nanoemulsion application increased thelevel of panelist's preference on wet noodles color from  2.2 (dislikes) to 4.05 (like).Key words: wet banana noodle, nanoemultion, colour,  vitamin A

Abstract

The noodle circulating in the market and which we often consume the main ingredient is wheat flour so that the nutrient components such as fiber and carotenoids contained in noodle is very minimal. To increase the content of fiber and carotene noodle it is necessary to substitute flour with local food containing fiber and carotenoids. For example breadfruit and pumpkin. This study aims to determine how the influence of the amount of pumpkin paste and breadfruit as the substitution of flour to the characteristics of wet noodles and to the color preferences test and to determine the effect of storage duration on carotenoid content of wet noodles. The experiment was conducted by non factorial randomized design by comparing the amount of pumpkin paste to breadfruit paste and storage duration. The results showed that water content, ash content and protein content were not influenced by the ratio of the number of pumpkin paste to breadfruit paste. But the fiber content increased from 1.22% to 3.16% and carotenoid levels from 0.07 ppm to 0.10 ppm. The color preference level increases from 1.86 (dislikes) to 3.35 (like). Time storage can lower carotenoid levels from 0.105 ppm at 0 days storage to 0.08 ppm at 4 days. The conclusion of flour substitution with breadfruit paste and pumpkin paste can increase the fiber content and wet carotenoid noodles. Storage results in decreased carotenoid levels.

Abstract

The aims of this research are to determine the effect of the concentration addition level of karamunting (Rhodomyrtus tomentosa) fruit extract on the quality of yogurt during 9 d storage period to increase the functionality of yogurt as a probiotic food, a source of antioxidants and the use of karamunting as a natural colorant for food. This research used a completely randomized design consisting of two factors, that is the concentration of karamunting fruit extract which consisted of 4 addition levels (0%, 12%, 15% and 18% w/w) and the storage period of yogurt which also consisted of 4 levels (0 d, 3 ds, 6 d and 9 ds). The parameters that have been observed in this research were pH, total acid, water content, fat content, protein content, color analysis, antioxidant activity and organoleptic tests (aroma, taste, viscosity and color) of the yogurt. The results showed that karamunting fruit extract had a significant effect on pH, total acid, color L*, a* and b*, and organoleptic (aroma, viscosity and color) of the yogurt, but had no significant effect on water content, fat content, protein content and flavor of the yogurt. Storage period had a significant effect on pH, total acid, protein content, color L*, a* and b*, and organoleptic (aroma, taste, viscosity and color) of the yogurt, but had no significant effect on water content and fat content of the yogurt. The addition of 18% (w/w) karamunting fruit extract and 9 d of storage period resulted in yogurt with the characteristics as follows pH 4.2; total acid 1.57%; water content 87.05%; fat content 3.66%; protein content 2.7%; color L* 72,24; a* 8.28; and b* 9.38 and organoleptic (aroma, taste, thickness and color) which were quite favorable, as well as a strong antioxidant activity value of 85.35 ppm IC50.

Abstract

Abstract The increasing variety of benefits of the butterfly pea flower requires the availability of dried butterfly pea flowers to replace fresh butterfly pea flowers. A study has been carried out on "The Influence of Packaging Type and Storage Time on the Quality Characteristics of Dried Butterfly Pea Flower (clitoria ternatea). The aim of the study was to determine the effect of the type of packaging and storage time on the quality characteristics of dried butterfly pea flowers. The study was conducted using an experimental method with a Completely Randomized Factorial Design (RALF). Treatment of packaging types: K1 = PolyPropylene (PP) Plastic Packaging and K2 = Aluminum Foil (AF) Packaging. Storage time: L0= 0 days; L1= 7 days; L2= 14 days; L3=21 days. The research was conducted with 3 replications. Data were analyzed using SPSS software version 20. Significantly different effects were tested by Duncan's test at the level of p=0.05. The results showed that the water content of the butterfly pea flower was 10.1% in the PP packaging and 9.7% in the AF packaging. Dried butterfly pea flowers contained a total phenol of 9.74 mg/g in PP packaging and 11.5 mg/g in aluminum foil packaging. IC50 values in PP and AF packaging were 242.7 and 224.4 ppm, respectively. The water content of the butterfly pea flowers increased significantly from 8.7% at 0 days of storage to 11.1% at 21 days of storage. Anthocyanin and flavonoid bioactive compounds were detected by positive tests up to 21 days of storage. The total phenol of the butterfly pea flower decreased significantly from 14.95 mg/g at 0 days of storage to 6.19 mg/g at 21 days of storage. IC50 value (antioxidant activity) increased from 140.1 ppm to 293.1 ppm during storage.Keywords: Butterfly pea flower, PolyPropylene and aluminium foil packaging, anthocyanin and phenol  AbstrakMeningkatnya ragam manfaat bunga telang menuntut tersedia bunga telang kering untuk menggantikan bunga telang segar.
