Abstract

The research aimed to know physical and chemical characteristics of Canna edulis Kerr and Dioscorea hispida Dennst unmodified and modified starch with cross-linking method. This research was divided into two stages. The first stage of the research was characterization of starch from Canna edulis Kerr and Dioscorea hispida Dennst and the second stage of the research was processing of modified starch from Canna edulis Kerr and Dioscorea hispida Dennst through crosslinking by using POCl at the concentration of 0.04%(v/v), 0.08%(v/v), dan 0.12%(v/v). There was no specific research design for the first stage of the research.  The collected data was tabulated. The research design for the second stage was non factorial completely randomized design with five replications. The results showed that C. edulis contained starch content (41.35%) and D. hispida (38.80%). C. edulis starch had amylose content (17.59%) and D. hispida starch 8.92%. The modification of C. edulis starch contained of phosphate (15.74 ppm) and D. hispida 9.54 ppm. The starch granule was found in C. edulis (20-50 μm) and starch granule was in D. hispida (4.23 to 4.52 μm). The physical and chemical characteristics of modified C. edulis and D. hispida starch were not similar to the unmodified starch. The amylose and starch contents in the modified starch was reduced, on the other hand, the phosphate content was increased, whereas the granule size was unchanged.3ABSTRAKPenelitian ini bertujuan untuk mengetahui karakteristik fisik dan kimia pati ganyong dan gadung sebelum dan setelah dimodifikasi dengan menggunakan metode ikatan silang (cross linking).

Abstract

The chemical compositions of tempe indicated their typical characteristics. As a result, the micro or macromolecule changes were likely to produce difference characteristic of tempe. High pressure carbon dioxide was a non-thermal processing method that could retain nutrition qualities, but it affects nonpolar and non covalent bond of substances. This research was conducted to evaluate chemical characteristics of tempe after being processed with high pressure carbon  dioxides. The experimental design was carried out in factorial completely randomized design with two factors, that were pressure at 7,6 MPa and 6,3 MPa, and holding time for 5, 10, 15, and 20 minutes. The proximate, calcium, vitamin B and texture were determined in control and treated tempe. The results showed that the treatments of pressures, the textures. The high pressure of both 7,6 MPa and 6,3 MPa sharply reduced the fat content of all the treated tempe and water content as well. It was only the pressure of 7,6 MPa decreased the protein content. The high pressure treatments increased the calcium of treated tempe but they did not affect the vitamin B.ABSTRAKKarakteristik khas tempe dihasilkan dari komponen makro dan mikromolekul penyusunnya sehingga perubahan konsentrasi senyawa di dalam tempe akan mengubah karaktersitiknya. Karbon dioksida bertekanan tinggi merupakan teknologi pengolahan tanpa panas yang dapat mempertahankan kualitas gizi produk walaupun dapat mempengaruhi senyawa nonpolar dan senyawa dengan ikatan non kovalen. Penelitian ini bertujuan untuk mengevaluasi karakteristik kimia dan tekstur tempe setelah diproses dengan karbon dioksida bertekanan tinggi. Percobaan menggunakan rancangan acak kelompok yang disusun faktorial dengan dua faktor perlakuan dan tiga kali pengulangan. Tempe yang diperlakukan dengan tekanan 7,6 MPa selanjutnya disebut tempe PS sedangkan yang diperlakukan dengan tekanan 6,3 MPa disebut tempe PC. Faktor pertama adalah tekanan dengan dua level perlakuan meliputi 7,6 MPa dan 6,3 MPa, sedangkan faktor ke dua adalah lama waktu tekanan dengan 4 level yaitu 5, 10, 15, 20 menit. Parameter yang diamati meliputi tekstur, kadar air, protein, lemak, abu dan karbohidrat, mineral kalsium, dan vitamin B1, B2, B pada tempe kontrol dan tempe perlakuan. Hasil penelitian menunjukkan bahwa tekanan, lama waktu tekanan dan interaksinya berpengaruh nyata terhadap kadar air, protein, lemak dan abu, tetapi tidak berpengaruh terhadap tekstur. Karbon dioksida tekanan tinggi baik pada 7,6 MPa maupun 6,3 MPa menurunkan kadar air dan lemak, tetapi kadar air tempe PC lebih tinggi dibanding tempe PS. CO2 3 tekanan 7,6 MPa yang menurunkan kadar protein. Perlakuan tekanan tinggi (7,6 MPa dan 6,3 MPa) juga menurunkan mineral kalsium tetapi tidak mempengaruhi kandungan vit B.

Abstract

The objective of this research was to asses relationship between temperature and storage time of capsaicin degradation of red chilli paste and to measure activation energy and shelf life using the Arrhenius model. The treatmens were storage temperature (20°C, 30°C, 40°C) and storage times (0, 2, 4, 6, 8, 10 weeks).  Parameters analyzed were capsaicin content using HPLC method, pH, and particle size.  The data was analyzed using linier regression and Arrhenius equation  The results showed that temperature condition and storage time affected capsaicin degradation of red chilli paste, unlike pH and particle size.  The longer storage time the lower capsaicin content.  The capsaicin content of red chilli paste stored at 30°C and 40°C in week-4 was 746,36 μg/g and 714,19 μg/g respectively, and it declined to 149,31 μg/g and 136,77 μg/g after being stored for ten weeks.  Research concluded that red chilli paste stored for 10 weeks at 20°C caused the lowest capsaicin degradation from   916.8029 μg/g  to 683.8097 μg/g. Degradation rate of capsaicin followed the first order reaction.  Arrhenius equation for capsaicin was  Y= -9356.3x + 27.836, (R=0.76), and activation energy was 18.581 kcal/mol.  Shelf life determination of capsaicin followed kinetic reaction equation of the fi rst order  i.e t = ln(Ao-At)/k.  The self life of red chilli paste stored at 20°C, 30°C and 40°C were 10.62 weeks, 8.62 weeks and 8.45 weeks respectively.ABSTRAKTujuan penelitian untuk mengkaji hubungan suhu dan lama penyimpanan terhadap degradasi capsaicin cabai merah giling serta menghitung energi aktivasi dan waktu simpan dengan pendekatan model persamaan Arrhenius. Perlakuan terdiri dari dua faktor yaitu suhu penyimpanan (20°C, 30°C, dan 40°C) serta lama penyimpanan (0, 2, 4, 6, 8 dan 10 minggu). Metode analisis untuk kadar capsaicin menggunakan HPLC. Analisis pendukung yaitu pH dan ukuran partikel.  Data disajikan dengan grafi k persamaan regresi linier dan persamaan Arrhenius.  Hasil penelitian menunjukkan bahwa kondisi suhu dan lama penyimpanan berpengaruh terhadap degradasi capsaicin cabai merah giling, namun, pH dan ukuran partikel tidak berpengaruh secara signifi kan.  Semakin lama penyimpanan maka kandungan capsaicin semakin menurun. Kadar capsaicin cabai giling yang disimpan pada suhu 30°C dan 40°C  pada minggu ke-empat masing masing sebesar 746,36 μg/g dan 714,19 μg/g menurun perlahan sampai pada  minggu ke-10 menjadi 149,31 μg/g dan 136,77 μg/g.  Dari hasil penelitian disimpulkan bahwa kadar capsaicin cabai giling yang disimpan pada suhu 20°C selama 10 minggu merupakan degradasi terendah dari 916,80 μg/g menjadi 683,81 μg/g.  Laju degradasi capsaicin mengikuti orde satu.  Persamaan Arrhenius untuk Capsaicin adalah Y= 27,836-9356,3x (R=0,76) dan energi aktivasi sebesar 18581,65 kal/mol. Penentuan umur simpan capsaicin mengikuti persamaan kinetika reaksi orde satu yaitu t =ln(Ao-At)/k, maka umur simpan capsaicin cabai merah giling yang disimpan pada suhu 20°C, 30°C dan 40°C berturutturut sebesar 10,64 minggu; 8,62 minggu dan 8,45 minggu.

Abstract

Modification of Canna starch through heat-moisture treatment (HMT) and gum xanthan (GX) treatment was conducted to improve the disadvantage of natural Canna starch in order to expand its usage in food industry, especially for bakery products. The research was arranged in a factorial randomized complete block design with three factors (temperature, incubation time, and GX concentrations) and three replications for each factor.  The modified Canna  starch by HMT possessed water content of 15 % as well as combination of temperature (80 °C and 100 °C), periods (8 and 16 hours) and concentration of GX (0; 0.5; 1; 1.5 and 2 %). The observed variables were the swelling power, water solubility index, water absorption index, baking expantion, and bulk density of modified Canna starch. The result showed that the modification of Canna starch by temperature, time of HMT and concentration GX produced modified starch with physical properties that significantly differ among treatments and natural starch.  Modified Canna starch by treatments of 80 °C, 8 hours, and 1 % xanthan gum concentration showed had swelling power 16.90 ± 0.48 g/g, water solubility index 10.28 ± 0.25 %, water absorption index 112.58 ± 0.38 %, baking expantion 0.94 ± 0.11 mL/g and bulk density 0.73 ± 0.026 g/mL which alike with wheat flour so that it can be further developed as wheat flour substitute on bakery products. ABSTRAKPenelitian modifikasi pati ganyong melalui perlakuan heat-moisture-treatment (HMT) dan penambahan gum xanthan (GX) dilakukan untuk memperbaiki kelemahan pati ganyong alami sehingga menjadi luas aplikasinya dalam industri pangan terutama produk rerotian.  Penelitian menggunakan rancangan acak kelompok faktorial dengan 3 perlakukan dan 3 ulangan.  Perlakuan yang diberikan adalah waktu (8 dan 16 jam), suhu (80 °C dan 100 °C), kadar air 15 % dan konsentrasi gum xanthan (0, 0,5; 1; 1,5; 2 %).  Data dianalisis dengan sidik ragam (ANOVA) pada α = 0,05, dilanjutkan dengan uji BNJ (α = 0,05). Parameter yang diamati swelling power (SP), indeks kelarutan dalam air (IKA), indeks absobsi air (IAA), derajat pengembangan (DP), dan densitas kamba (DK) pati ganyong termodifikasi. Hasil penelitian menunjukkan bahwa modifikasi pati ganyong dengan kombinasi perlakuan suhu dan waktu HMT serta konsentrasi GX menghasilkan pati termodifikasi dengan sifat fisik yang berbeda nyata antar perlakuan maupun pati alaminya.  Modifikasi pati ganyong dengan HMT pada suhu 80 °C, waktu 8 jam, kadar air pati 15 % dan konsentrasi gum xanthan 1 % dapat menghasilkan pati ganyong yang sifat fisiknya mendekati tepung terigu kadar protein sedang dan berbeda dengan pati ganyong alami.

Abstract

Palembang fish crackers have a thick characteristic with a strong fishy aroma. Puffing of the thick fish cracker requires particular technique, for example the deep-frying techniques should use two different heating temperatures to obtain good quality of crackers. Another alternative method is to use heat from microwaves. One of the disadvantages of crackers that are processed with heat from the microwave is the easiness of the crackers lose its crispness. This study aimed to analyze the shelf-life of fish crackers puffed by microwave heat and deep-frying technique in some types of packaging. The research design was a factorial completely randomized design with two factors namely the type of packaging (polypropylene, nylon, metalized plastic) and type of crackers (microwaved and fried). Analysis of variance showed that all treatments have a significant effect on water content.  The indicator used for the prediction of shelf-life is water content. The water content changes during storage at room temperature for all treatments followed a first-order kinetic with the lowest k value for fish cracker packed in metalized plastic packaging with 57 days storage time (microwavable fish crackers) and 45 days (fried fish crackers)
