Abstract

The purpose of this research was to observe the effects of threadfin breams surimi (Nemiptarus nematophorus) and mussel (Pilsbryoconcha exilis) to physical, chemical and sensory characteristics of nugget. This research used randomized block design (RBD) consisted of one factor treatment and three replications. Factor treatment consisted of combination ratio threadfin breams surimi and mussel 100% : 0%, 75% : 25%, 50% : 50%, 25% : 75%, 0% : 100%. The variables observed were physical characteristics (elasticity), chemical characteristics (moisture content, ash, protein, fat, carbohydrate, and iron) and sensory analysis on appereance, flavour, taste and texture of the final products. Different combinations of threadfin breams surimi and mussel had significant effect on elasticity (222.53 gf, 278.33 gf, 300.66 gf, 312.13 gf, 452.86 gf), ash content (3.26%, 2.51%, 2.23%, 1.63%, 1.45%), protein content (8.27%, 12.11%, 14.8%, 17.14%, 20.73%), carbohydrate content (17.32%, 14.34%, 11.11%, 8.42%, 3.5%), and iron (23.61%, 18.56%, 12.77%, 7.24%, 1.54%). Based on the results, the greater addition of surimi concentration caused the increasing value of elasticity, protein, and water content. While the greater addition of mussel concentration resulted on the increased value of ash, fat and iron. This research showed that the combination of 75% threadfin breams surimi and 25% mussel produced on nugget with the best characteristics.

Abstract

The purpose of this research was to observe antioxidative activity of chitosan monosaccharides complex. The research was conducted in May until June 2013 at chemistry and microbiology laboratory, study program of agricultural technology. All treatment are chitosan, chitosan glucose complex, chitosan galactose complex and chitosan fructose complex using a invitro testing. The parameters were brown color analysis, analysis antioxidant activity with DPPH and reducing power method . The result showed that all chitosan monosaccharides complex demonstrated better antioxidative than chitosan. It is indicated that Maillard reaction product (MRP) exhibited antioxidant activity. The brown color analysis (0.031-0.224), antioxidant antioxidant analysis with DPPH method of IC50 (92-131 ppm) and reducing power method was 1.059-1.274. Chitosan galactose complex (A2) is the best to antioxidative from all treatments. Chitosan monosaccharides complex could be used as natural preservatives, edible packaging (film and couting) and food additive.

Abstract

The purpose of this research was to observe antioxidant activity of lotus leaves extract (Nelumbo nucifera). The extraction  process was carried out using three different solvents namely methanol, ethyl acetate and n-hexane. The observed parameters were extraction yields phytochemical compounds (alkaloid, flavonoid and tanin) and antioxidant activity using DPPH method. The results showed that the methanol extract exhibited the highest yield with a value of 0.708% and had a flavonoid tannin content of 1161 ppm. The antoxidant activity of the same extract as indicated by IC50 value was 199 ppm. The extract ethyl acetate and n-hexane solvents did not show potential antioxidant activities

Abstract

The purposes of the research were to compare the method of makes daruju (Acanthus illicifolius) leaves the tea to determine the bioactive compounds. The research was conducted from June 2016 until December 2016. This research uses laboratory experimental methods and data analysis was done descriptively. The parameters observed testing phytochemical compounds flavonoids, alkaloids, tannins, saponins, phenols and steroids and analysis of antioxidant with DPPH and reducing power. The result showed that the crude extract daruju leaves tea has a bioactive compound acts as an antioxidant compound. The result of antioxidant activity DPPH methods was medium in the methanol extract with IC50 values of 101.4 ppm and boiled extract (217.5 ppm) and a very weak activity in the brewed extract (294.9 ppm) while the reducing power method shown good results in the methanol extract instead of boiled extract and brewed extract. From the results of the antioxidant activity of these three methods, the use of extraction are best is methanol. While the comparing from the method of makes daruju leaves the are best is boiled extract than brewed extract.

Abstract

The purpose of research was to determine the effectiveness use of chitosan as a coating solution at a concentration (0%, 1.5%, and 3%) the quality and shelf life minced fish meat snake head fish (Channa striata) during storage. The research used the Factorial randomized block design (RBD) with two factors of treatment and two replications. Factor treatment consists of treatment differences chitosan concentration (K0 = 0%, K1 = 1.5%, and K3 = 3%) and storage time (H0 = without storage, H1 = 3 days, 6 days = H2, and H3 = 9 days). Parameters observed test total volatile base, total plate count, and protein content. The results showed that differences in chitosan concentration and storage time significantly affected total volatile base (TVB) and total plate count (TPC). The use of 3% chitosan solution gives the best results based on the parameters protein content, TVB, and total plate count (TPC). Best treatment combination for quality meat minced snake head fish found in K2H3 treatment.

Abstract

The purpose this study was to determine the effect of different cooking methods (boiling, steaming, and deep frying) on chemical and amino acids composition of silver rasbora fish (Rasbora argyrotaenia). This method used completely randomized design (CRD) with three replications. Fresh silver rasbora served as control. During cooking, temperature was measured using thermocouple every minutes until done. The result showed that different cooking methods contributed to changes in chemical dan amino acid composition of silver rasbora fish. Steaming was the best method to maintain the high protein level of fish composed to boiling and deep frying. Results of analysis showed that the lowest water content (7.85%) was fand in deep fried fish while the lowest fat level was found in steamed fish with the value of 2.05%. The highest protein level was found in steamed fish is (12.223 mg/mL). Glutamic acid, leucine, proline and lysine were in high proportion of amino acid content in silver rasbora fish.

Abstract

Burgo merupakan salah satu menu makanan dengan bahanbdasar tepungktapioka danktepung beras kemudian dibentuk dengan cara digulung. Penelitian ini bertujuan untuk menentukan perlakuan suhu dan waktu pengovenan terbaik pada pembuatan bumbu kaldu burgo instan. Penelitian ini menggunakan analisis Rancangan Acak Kelompok dengan 2 faktor. Faktor I suhu pengeringan terdiri dari 3 level (60?, 80?, dan 100?) dan faktor II lama pengeringan terdiri dari 3 level (6 jam, 9 jam, 12 jam). Parameter  pengamatan meliputi warna, total padatan terlarut dan organoleptik. Hasil penelitian dengan perlakuan waktu dan suhu menunjukkan perbedaan signifikan terhadap nilai total padatan terlarut. Total padatan terlarut yang diperoleh  mengalami peningkatan, sejalan dengan bertambahnya waktu dan suhu pengovenan dan berpengaruh nyata terhadap waktu dan suhu pengovenan. Berdasarkan tabel hasil pengamatan jumlah tanggapan yang benar untuk warna, rasa, aroma, dan kenampakkan adalah 18, 18, 18, dan 19. Sedangkan berdasarkan tabel binomial diperoleh minimum tanggapan yang benar pada taraf 5% adalah 18, sehingga sampel yang tidak berbeda nyata pada warna (suhu 80? selama 12 jam), rasa (suhu 80? selama 9 jam), aroma, dan kenampakan (suhu 100? selama 6 jam). Hasil penelitian terbaik terdapat pada perlakuan yang menggunakan suhu 80? selama 12 jam dengan rerata total padatan terlarut 42,35 mg/L, dan hasil organoleptik mendekati sampel burgo pasaran pada warna (kekuningan) dan aroma
