Moisture Treatment

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. Sifat fisik pati ganyong termodifikasi tersebut adalah SP 16,90 ± 0,48 g/g, IKA 10,28 ± 0,25 %, IAA 112,58 ± 0,38 %, DP 0,94 ± 0,11 mL/g, dan DK 0,73 ± 0,026 g/mL.Kata kunci: Pati ganyong; gum xanthan; HMT; modifikasi; sifat fisik

Heat moisture treatment (HMT) can be a useful method of wheat flour functionality modification, improving the nutritional value of pasta along with grape peels (GPF) addition. The aim of this study was to investigate the combined effects of HMT temperature, time, and moisture and GPF level on dough and pasta properties. Dough rheology and texture, pasta color, texture, total polyphenols (TPC), dietary fiber (DF), and resistant starch (RS) contents were evaluated. Furthermore, an optimization was performed based on Response Surface Methodology (RSM) and desirability function. The results showed that HMT regime and GPF determined proportional dough viscoelastic moduli and firmness increase. On the other hand, cooked pasta firmness and gumminess decreased with HMT conditions and GPF level rise. Higher pasta RS and DF content was promoted by HMT and GPF components. The reduction effect of HMT on TPC was countered by the incorporation of GPF, a rich source of polyphenols. The optimization revealed that the recommended wheat flour treatment regime would be 87.56 °C, 3 h, and 26.01% moisture, while the quantity of GPF that could be added was 4.81%. For these values, the maximum functional and nutritional values would be achieved with minimum negative impact on pasta quality.
