Abstract

Nasi kuning instan menjadi salah satu alternatif menu sarapan pagi karena memiliki waktu penyajian yang singkat. Tujuan penelitian ini adalah untuk menghasilkan formula terbaik produk nasi kuning instan dengan waktu rehidrasi yang optimum dan menentukan karakteristik fisikokimia produk nasi kuning instan. Faktor yang diuji adalah formulasi bumbu (kontrol dengan menggunakan bumbu instan, formula A menggunakan 1 paket bumbu nasi kuning, formula B menggunakan 1,25 paket bumbu nasi kuning dan formula C menggunakan 1,50 paket bumbu nasi kuning) dan kadar amilosa beras (rendah, sedang dan tinggi). Hasil uji analisis one way anova menunjukkan bahwa antara formulasi dan kadar amilosa beras berbeda secara nyata dari karakteristik fisikokimia nasi kuning instan (p<0,05). Formula dan nasi kuning instan yang terpilih adalah formula 1,25 paket bumbu nasi kuning dari beras Sintanur dengan kadar amilosa rendah adalah waktu rehidrasi 4,59 menit, rendemen 90,23%, volume pengembangan 30,89%, daya serap air 49,68%, densitas kamba 0,62 g/mL, nilai °Hue diatas 90%, dan nilai kekerasan 74,03%. Produk ini mengandung kadar air 8,07%, abu 3,35%, protein 9,19%, lemak 2,08%, karbohidrat 76,32%, dan kadar pati 64,11 %. Formulation, Characterization, and Optimization of the Rehydration of Yellow Rice Instant.Instant yellow rice is an alternative to breakfast because it has a short testing time.

Abstract

Handling of bulk cooking oil is not good, cause a decrease in the quality of cooking oil when in storage in the selling process. Wrapping packaging of bulk cooking oil that is not appropriate and direct interaction with the sun and microbes can change the quality of cooking oil. Besides the fabrication of bulk cooking oil, to make people uneasy. For it is necessary for the analysis of bulk cooking oil quality on a variety of storage (closed and open) in the traditional markets in in Jabotabek Area through the physical trials and chemical tests. Analysis physics for odor and color is done organoleptic. Chemical analysis of water content using gravimetric method. Determined acid number by titration of alkalimetri with NaOH. Peroxide number determined with Tio 0.02 N. For example pelicans oil test alcohol 5N KOH.Based on this research, to test the physics of odor obtained normal results for sealed storage and smelling a bit stale at week 4 and to 5 in the open storage, while the average for the color of pale yellow oil, yellow, until golden brown. To test the chemical in terms of water content and acid number in the average closed storage meets the requirements of ISO - 3741 - 2002, while the open storage of the average moisture content does not meet the requirements for the number of acid still meet the quality standards II. The results of the analysis of peroxide numbers in a closed storage on average to meet the requirements of ISO - 3741 - 1995, while the open storage do not meet the standards. To test the oil did not reveal any falsification pelicans.Keywords : analysis, cooking oil, gravimetry, alkalimetry titration

Abstract

In the manufacture of jelly milk drinks are necessary also other additional ingredients such as sugar is used as a sweetener in the manufacture of jelly while working to ease hydrocolloid dispersion. Potassium citrate is used for auxiliary materials, especially the formation of gel texture carrageenan, citric acid is used as a substance other than flavor in soft drinks, used also as an inhibitor of microbial growth in milk jelly drinks.An analysis of milk jelly beverage products, including the organoleptic analysis of where the testing is done against the panelists to determine the level of liking for the product. Viscosity to determine the viscosity of the product before the final product, the analysis is conducted to determine the strength of the gel on which the final product gel strength will be measured by looking at the gel fracture when pressed with a certain weight. PH measurement is necessary to know the level of acidity flavor obtained from addition of citric acid and then measuring brix to see the level of sweetness of the product because of sweetener used is pure sugar. In this study the analysis of protein levels because the products contain milk which is produced by converting nitrogen compounds into ammonium sulfate and then elaborated by NaOH, whereas the liberated ammonia was tied with H3BO4 and then titrated with HClKey words: Gels, hydrocolloid, sugar, potassium citrate, citric acid, organoleptic, viscosity, gelstrength, pH, brix, protein levels

Abstract

Dry, scaly, rough skin conditions accompanied by wrinkles and black spots characterize the skin that experiences premature aging. One of the causes of premature aging is free radicals. These free radicals can be overcome with natural or artificial antioxidants. Natural antioxidants are found in fruits and vegetables, one of which is tomatoes. Tomatoes in direct use are less effective, so they are made in the form of hand and body cream. Production of vegetable tomato and cherry tomato extracts fruit extraction and maceration using 96% ethanol, then concentrated with a rotary evaporator until the extract is thick. The extracts of vegetable tomatoes and cherry tomatoes were then tested for phytochemical, antioxidant activity, and identification of compounds with LC-MS, then applied to hand and body cream with a concentration of 1% and 3% with codes F0, F1, F2, F3, and F4. Hand and body cream of tomato extract are tested by measuring pH, viscosity, specific gravity, total microbial Contamination, homogeneity and testing for antioxidant activity using the DPPH method. Phytochemical test results showed that flavonoid compounds were present in both extracts. The antioxidant activity of vegetable tomato ethanol extract was obtained with an IC50 value of 947.81ppm, and an IC50 value of 473.51 ppm was obtained for cherry tomato extract. From the LC-MS analysis, the compounds contained in cherry tomatoes, namely esculeoside A and B as cytotoxic activity, dehydrotomat as an antibacterial, kaempferol-3-O-rutinoside as an antioxidant, and tomatidine as an antibiotic. Antioxidant activity of hand and body cream, hand and body cream F4 (964.05 ppm), hand and body cream F3 (1001.97 ppm), hand and body cream F2 (1033.73 ppm), hand body cream F1 (1036.61 ppm), and hand and body cream F0 (1486.14 ppm). Hand and body cream cherry tomato extract 3%, formula 4 (F4), has the highest antioxidant activity. It can be concluded that the addition of extract concentration affects the antioxidant activity value of hand and body cream. Body cream F2 (1033.73 ppm), hand body cream F1 (1036.61 ppm), and hand and body cream F0 (1486.14 ppm). Hand and body cream cherry tomato extract 3%, formula 4 (F4), has the highest antioxidant activity. It can be concluded that the addition of extract concentration affects the antioxidant activity value of hand and body cream. Body cream F2 (1033.73 ppm), hand body cream F1 (1036.61 ppm), and hand and body cream F0 (1486.14 ppm). Hand and body cream cherry tomato extract 3%, formula 4 (F4), has the highest antioxidant activity. It can be concluded that the addition of extract concentration affects the antioxidant activity value of hand and body cream.
