Abstract

AbstractMinimally-processed mango is a perishable product due to high respiration and transpiration and microbial decay. Edible coating is one of the alternative methods to maintain the quality of minimally - processed mango. The objective of this study was to evaluate the effects of bionanocomposite ediblecoating from tapioca and ZnO nanoparticles (NP-ZnO) on quality of minimally - processed mango cv. Arumanis, stored for 12 days at 8°C. The combination of tapioca and NP-ZnO (0, 1, 2% by weight of tapioca) were used to coat minimally processed mango. The result showed that application of bionanocomposite edible coatings were able to maintain the quality of minimally-processed mango during the storage periods. The bionanocomposite from tapioca + NP-ZnO (2% by weight of tapioca) was the most effective in reducingweight loss, firmness, browning index, total acidity, total soluble solids ,respiration, and microbial counts. Thus, the use of bionanocomposite edible coating might provide an alternative method to maintain storage quality of minimally-processed mango.AbstrakMangga terolah minimal merupakan produk yang cepat mengalami kerusakan dikarenakan respirasi yang cepat, transpirasi dan kerusakan oleh mikroba. Edible coating merupakan salah satu alternatif metode untuk mempertahankan mutu mangga terolah minimal. Tujuan dari penelitian ini adalah untuk mengevaluasi pengaruh pelapis bionanokomposit dari tapioka dan nanopartikel ZnO (NP-ZnO) terhadap mutu mangga terolah minimal cv. Arumanis yang disimpan selama 12 hari pada suhu 8oC. Kombinasidari tapioka dan NP-ZnO (0, 1, 2% b/b tapioka) digunakan untuk melapisi mangga terolah minimal. Hasil menunjukkan bahwa pelapisan bionanokomposit mampu mempertahankan mutu mangga terolah minimal selama penyimpanan. Bionanokomposit dari tapioka + NP-ZnO (2% b/b tapioka) paling efektif dalam menghambat penurunan susut bobot, kekerasan, indeks pencoklatan, total asam, total padatan terlarut, respirasi dan total mikroba. Dengan demikian, pelapis bionanokomposit dapat digunakan sebagai salah satu alternatif untuk mempertahankan kualitas mangga terolah minimal selama penyimpanan.

Abstract

AbstractMango is one of Indonesia export comodities which vulnerable to decay during transportation and storage. Coating is known as an effective method to overcome such shortcomings of mango during storage. The objective of this study is to examine the effect of carrageenan-based bionanocomposite coating application for maintaining quality of mango type Gedong gincu stored at 20 oC as well as characterize the mechanicaland water vapor barier properties of resulting film. Zinc oxide nanoparticles (ZnO NPs) (1 % w/w carrageenan) and beeswax (3 % v/v solution), as hydrophobic component, were incorporated into carrageenan polymer to produce bionanocomposite solution. The results showed the mechanical and water vapor barrier properties of carrageenan films were improved by the addition of beeswax and ZnO NPs. N1B1 (carrageenan + beeswax + ZnO NPs) emerged as the most effective coating formulation to delay the change of weightloss, firmness, CO2 production, total acidity as well as alteration in color parameters (L, a and b) of mangoduring storage. Carrageenan-based bionanocomposite coating was potential as alternative method to keepthe quality of mango during storage.AbstrakMangga merupakan salah satu komoditas ekspor Indonesia yang rentan mengalami kerusakan selama transportasi dan penyimpanan.

Abstract

AbstractAnthocyanins from different sources have been reported for its potential as thermal process indicator. This research aimed in particular to study the color degradation kinetics of anthoyanin from Roselle and in general to provide alternative natural indicator for thermal process. Roselle’s anthocyanin extract was incorporated into 3 biodegradable films (i.e agar, pectin, PVA). Thermal degradation kinetics of anthocyanin’s color (ΔE and Chroma) in biodegradable film was studied at selected temperatures (80oC, 90oC, and 100oC). The color change was observed at minute 0, 30, 60 and 120 by computer vision method. The results showed that anthocyanin incorporated into PVA film had the highest value of activation energy (Ea), while anthocyanin incorporated into pectin film had the smallest value of Ea. Lower value of Ea indicating that the anthocyanin chroma is easily degraded at low temperature. Higher value of Ea indicating that it needshigher energy or higher temperature to degrade the color. The results of this study showed that anthocyanin in PVA film can be selected as indicator for high temperature thermal process (e.g. sterilization), while anthocyanin in pectin film can be used in lower temperature thermal process (e.g. pasteurization). AbstrakPotensi antosianin dari berbagai sumber sebagai indikator proses termal alami telah banyak dilaporkan. Penelitian ini bertujuan mempelajari kinetika degradasi warna film-antosianin serta menentukan kombinasibiodegradable film-antosianin terbaik sebagai alternatif indikator proses termal. Pengamatan kinetik ini dilakukan pada suhu 80oC, 90oC, dan 100oC dan parameter degradasi warna yang diukur adalah ΔE danChroma. Hasil penelitian menunjukkan bahwa antosianin pada film PVA mempunyai nilai energi aktivasi (Ea) paling besar, sedangkan antosianin pada film pektin mempunyai nilai Ea paling kecil. Nilai Ea degradasiwarna antosianin yang kecil pada film pektin menunjukkan bahwa degradasi warna sudah dapat berjalan pada suhu yang rendah. Sedangkan nilai Ea degradasi warna antosianin yang lebih besar pada film PVA menunjukkan bahwa antosianin pada film tersebut merupakan yang paling sensitif terhadap perubahan suhu dan paling signifikan perubahan warnanya. Namun perubahan warna yang signifikan pada antosianinpada film PVA membutuhkan suhu yang lebih tinggi sehingga lebih tepat untuk digunakan sebagai indikator pada proses termal dengan suhu yang tinggi (misalnya sterilisasi), sedangkan antosianin pada film pektin dapat digunakan pada proses termal dengan suhu yang lebih rendah (misalnya pasteurisasi).

Abstract

Snake fruit (Salacca edulis Reinw.) is one of the leading agricultural commodities in Indonesia with sweet taste and crispy texture. Unfortunately, it has a short storage life due to high respiration and transpiration and fungal decay. Therefore, the present study was aimed to evaluate the effect of pectin-based nanocomposite coating on postharvest quality of snake fruit stored at ambient temperature. The pectin solution was prepared by dispersing ZnO NPs (2%, w/w to pectin) and stearic acid (1%, w/w to pectin) into a pectin solution (1%, w/v in distilled water). Snake fruits were coated by dipping method and stored at room temperature during 14 days. The quality parameters and microbial growth were evaluated periodically. Results showed that application of nanocomposite coating on snake fruit could reduce weight loss (from 41.18±1.77% to 27.78±1.20%) and inhibit microbial growth (from 7.52 log cfu/g to 4.48 log cfu/g) significantly. The coating layer was transparent so did not affect the appearance of snake fruit. Thus, these results suggest that the pectin-based nanocomposite coating might provide an alternative method to maintain storage quality of snake fruit.

Abstract

Sliced kebab meat is produced by roasting raw kebab meat to make it easier to distribute at cold temperature. However, its quality could be damaged if it is distributed for long period, so preservative is needed. The study consisted of two phases. The first phase determined the type and concentration of preservatives consisting of potassium sorbate at concentrations of 750, 1000, 1250 ppm, and sodium nitrite at concentrations of 30, 50, and 100 ppm used a completely randomized design. The second phase was carried out to study the stability of sliced kebab meat with the addition of selected preservatives during refrigeration storage (5°C). The results showed that the best treatment was the use of potassium sorbate at 1250 ppm which resulted in the lowest mean total plate count (TPC), mold yeast values, and the highest scores of sensory attributes. The stability could be maintained at refrigeration storage for up to 14 days. On the 14th day, the sliced kebab meat had a pH value of 6.59, aw of 0.70, total acidity of 0.55%, TPC of 2.81 logs CFU/g, the color score of 3.8 (slightly brownish red), the aroma of 4 (typical meaty smell), the taste of 3.8 (slightly the savory), the texture of 3.5 (neutral) and overall of 3.5 (rate as liked).

Abstract

The aim of this study was to learn more about the macromolecular distribution of the food matrix system in the traditional food Dodol Ulame in order to better understand the interactions between starch, fat and sugar. Microstructural stages included dye selection, staining/coloring, material mixing, and observation. The starch was stained with APTS and the fat with Nile red. The starch was stained using the double staining method with covalent labeling. The samples were analyzed with a Zeiss Inverted LSM 800 AXIO Observer equipped with an AXIO cam 503 color camera and an excitation wavelength of 665 nm and 543 nm. The results indicated that GR was polyhedral. Fat and sugar are evenly distributed in the matrix system. Some of the fat interacts with the starch granules to form a coating that prevents the starch from interacting with the sugar and inhibits the imbibition of water into the starch granules at 50 °C and 70°C. Amylose escapes from the granules and reacts with the sugar solution at a higher temperature of 90 °C, while the free fat acts as a lubricant between the particles. This shows how flour, fat and sugar interact to affect the manufacturing process and the final properties of dodol ulame.

Abstract

Ketupat is an Indonesian indigenous food made from rice which is wrapped by young coconut leaves and cooked into the boiling water. Storage temperatures might affect the physicochemical and microbiological characteristics of ketupat. The objective of this research was to observe the effect of 2 rice varieties with different amylose content and the percentage of ketupat filling on the change of physicochemical and microbiological characteristics of ketupat during storage at cold temperature (T= 5 oC; RH= 19,2 %). Ketupat was produced by using two rice varieties, namely IR 64 and Pandan Wangi. The percentage of ketupat filling resulted in higher ketupat hardness during storage. In addition, the hardness of ketupat increased during storage. The percentages of ketupat filling did not affect pH and aw of the ketupat during storage; however, the higher the percentages of ketupat filling resulted in the lower water content. The water content and pH did not change during storage. Ketupat stored at cold temperature was able to maintain the microbiological quality until the 9th day.

Abstract

Beras merupakan makanan pokok bagi lebih dari setengah penduduk dunia. Ketupat merupakan produk olahan beras yang menjadi bagian dari budaya Indonesia. Ketupat memiliki umur simpan yang singkat. Suhu penyimpanan yang berbeda diduga memengaruhi profil tekstur ketupat. Penelitian bertujuan untuk memperoleh data pengaruh amilosa beras dan persentase pengisian ketupat pada perubahan profil tekstur ketupat selama penyimpanan pada suhu yang berbeda. Karakterisasi tekstur ketupat dilaksanakan pada dua suhu, yaitu suhu ruang dan dingin. Ketupat dibuat dengan beras varietas IR 64 dan Pandan Wangi. Selama penyimpanan suhu ruang, beras beramilosa tinggi serta persentase pengisian ketupat yang lebih rendah diperoleh ketupat dengan elastisitas yang rendah. Elastisitas meningkat selama penyimpanan pada suhu ruang, tetapi selama penyimpanan suhu dingin elastisitas tidak berubah. Amilosa beras serta persentase pengisian yang lebih tinggi diperoleh nilai daya kunyah ketupat tinggi selama penyimpanan disuhu dingin, tetapi saat kondisi suhu ruang kadar amilosa tidak berpengaruh pada daya kunyah. Selama penyimpanan, baik disuhu ruang ataupun suhu dingin, nilai daya kunyah ketupat meningkat. Kelengketan ketupat tidak dipengaruhi oleh kandungan amilosa dan persentase pengisian ketupat. Rice is a staple food for more than half of the world's population. Ketupat is an Indonesian indigenous food made from rice. However, ketupat has short a shelf life. The differences in storage temperatures might affect the texture characteristics. The objective of this research was to observe the effect of amylose content and the percentage of ketupat filling on the change of texture characteristics of ketupat during storage at different temperatures. Characterizations of ketupat during storage were conducted in two temperature conditions, i.e. room temperature and cold temperature. Ketupat was produced by using IR 64 and Pandan Wangi rice varieties. The higher amylose content and the lower percentage of ketupat filling resulted in the lower of ketupat springiness during storage at room temperature. The springiness of ketupat also increased during storage at room temperature, but it did not change significantly during storage at cold temperature. The higher amylose content and the percentage of ketupat filling resulted in the higher of ketupat chewiness during storage at cold temperature. However, at room temperature, the chewiness was not affected by the amylose content. The chewiness of ketupat increased during storage at room temperature and cold temperature. The amylose content and the percentages of ketupat filling did not affect adhesiveness, of the ketupat during storage.
