This research was conducted to use native sago starch (PSA), hydroxypropyl sago starch (PSHP, molar substitutions (MS) 0.058) and hydroxypropyl-acetyl sago starch (PSHP-AS MS 0.058; degree of substitutions (DS) 0.061) as basic materials for edible film, prepared with 3, 4 and 5% w/v. Edible film solution was prepared at 70oC for 30 min with glycerol (0.5% w/v) addition as plasticizer, and then dried-up using oven at 40oC. Analysis was conducted for physical characteristics of edible films including film thickness, elongation, tensile strength, water vapor transmission rate (WVTR), and solubility. Sago starch film produced by PSA, PSHP (MS 0.058) and PSHP-AS (MS 0.058-DS 0.061) showed different characteristics compared to PSA, including thickness, tensile strength, elongation, and WVTR of the films. The best edible film produced by PSHP‑AS (5%, w/v) with lowered WVTR was 11.27 g H2O/m2 h, its thickness was about 0.085 mm, tensile strength was 13.91 MPa, elongation was 0.32% and solubility was 90,595%.

Native sago starch (NSS) was chemically modified with propylene oxide. Hydroxypropylation reaction was aranged using 2.5, 5.0 and 7.5 mL in alkaline condition at 40oC for 24 h. The objective of this study was to identify the effect of propylene oxide on the properties of hydroxypropyl sago starch (HPSS). In addition, swelling power, starch solubility, paste clarity, amylograph properties and starch color were measured. Fourier transform infrared (FT-IR) spectroscopy was used to examine the substitution of hidroxypropyl group. The result showed that molar substitution (MS) HPSS was 0.03-0.09. Swelling power (21.32-51.11 g/g), initial gelatinisation temperature (IGT) (58.5-67.5 oC) and peak ge- latinisation temperature (PGT) (69-75 oC) was the lowest in comparison to NSS was 51.11-77.78 g/g,71.50-72 oC and77.25-79.50 oC respectively for swelling power, IGT and PGT. Paste clarity 59.23-82.18; 35.23-42.09 and 35.70-44.25%T respectively for hidroxypropyl sago starch (HPSS) Tuni, HPSS Ihur and HPSS Molat was highest compared to NSS56.20, 33.27 and 30.22 %T respectively for NSS Tuni, NSS Ihur and NSS Molat. The color of HPSS (L* 93.39-97.58)was highest compared to NSS (L* 62.75-65.01) with a* (0.25-1.38) and b* (6.38-9.37) was the lowest.ABSTRAKPati sagu alami (PSA) telah dimodifikasi dengan propilen oksida. Hidroksipropilasi dengan variasi propilen oksida berturut-turut 2,5, 5,0 dan 7,5 mL dalam suasana alkali pada suhu 40 oC selama 24 jam. Tujuan penelitian ini adalah untuk mempelajari pengaruh variasi propilen oksida terhadap sifat-sifat pati sagu hidroksipropil (PSHP). Parame- ter perubahan yang diukur meliputi kemampuan menggelembung, daya larut, kejernihan pasta, sifat amilografi dan warna pati. Spektra fourier transform infrared (FT-IR) digunakan untuk menunjukkan tersubtitusinya gugus hidrok- sil oleh gugus hidroksipropil. Hasil penelitian menunjukkan bahwa molar subtitusi (MS) PSHP adalah 0,03-0,09. Sifat-sifat seperti kemampuan menggelembung 21,32-51,11 g/g, suhu awal gelatinisasi (SAG) 58,5-67,5 oC dan suhu puncak gelatinisasi (SPG) 69-75 oC adalah rendah jika dibandingkan dengan PSA yaitu 51,11-77,78 g/g,71,50-72 oC dan 77,25-79,50 oC berturut-turut untuk kemampuan menggelembung, SAG dan SPG. Kejernihan pasta 59,23-82,18;35,23-42,09 dan 35,70-44,25 %T berturut-turut untuk pati sagu hidroksipropil Tuni (PSHPT), PSHP Ihur (PSHPI) dan PSHP Molat (PSHPM) lebih tinggi dibandingkan PSA 56,20, 33,27 dan 30,22 %T berturut-turut untuk PSA Tuni, PSA Ihur dan PSA Molat. Warna PSHP (L* 93,39-97,58) menunjukkan nilai yang lebih tinggi jika dibandingkan dengan PSA (L* 62,75-65,01) dengan nilai a* (0,25-1,38) dan nilai b* (6,38-9,37) rendah.

The objective of this study was to characterize modified Ihur sago starch as affected by treatment of acid hydrolysis. A completely randomized experimental non-factorial design was used in this research with four levels of treatments, i.e. native ihur sago starch, HCl concentrations of 1.1 N, 2.2 N, or 3.3 N, subsequently. Physical properties such as color, swelling power, solubility, and paste clarity were measured in this research. Moisture, ash, and amylose content were determined as chemical properties, while the resistant starch (RS) content was determined for its functional properties. Results showed that starch treated with acid hydrolysis caused changes to physical properties in comparison with native starch. These included higher (80.93–81.89) degree of whiteness (L*) than native starch (80.29), lower redness (a*) and yellowness (b*) than native (8.26 and 18.24) having the value of 5.13–6.34, and 13.21–15.39, respectively. Acid hydrolysis not only caused a decrease in swelling power (43.88–50.56%), but also an increase in solubility (8.92–12.34%) and paste clarity (74.70–77.73% T) compared to native starch. Higher moisture and ash content having the value of 8.72–15.01% and 0.22–0.37%, correspondingly but lower amylose (18.29–27.22%) and RS content were obtained by acid hydrolysis starch in contrast to native starch. The modified starch has improved heat stability with smaller breakdown viscosity, and setback viscosity less than native starch, and is easily to gelatinize. ABSTRAKPenelitian ini bertujuan untuk mengkarakteristik pati sagu ihur alami (PSIA) yang dimodifikasi dengan perlakuan hidrolisis asam. Rancangan yang digunakan yaitu rancangan acak lengkap non-faktorial dengan empat taraf perlakuan yaitu PSIA, hidrolisis asam (PSIHA) menggunakan HCl 1,1 N, 2,2 N, atau 3,3 N. Parameter yang diukur meliputi karakteristik fisik antara lain warna, kemampuan menggelembung, daya larut, kejernihan pasta, dan sifat amilografi. Karakteristik kimia meliputi kadar air, kadar abu, dan amilosa sedangkan karakteristik fungsional yaitu kadar pati resistan (RS). Hasil penelitian menunjukan bahwa perlakuan hidrolisis asam menyebabkan perubahan terhadap sifat fisik warna pati dimana nilai kecerahan (L*) pati hidrolisis asam (80,93–81,89) lebih tinggi dibandingkan PSIA (80,29). Sebaliknya nilai kemerahan (a*) dan kekuningan (b*) PSIHA (5,13–6,34 dan 13,21–15,39) lebih rendah dibandingkan PSIA (8,62 dan 18,24). Perlakuan asam juga menyebabkan kemampuan menggelembung PSIHA (43,88–50,65%) mengalami penurunan dibandingkan PSIA, tetapi meningkatkan daya larut (8,92–12,34%) dan kejernihan pasta (74,70–77,73% T). Untuk sifat kimia, kadar air pati sagu hidrolisis asam (8,72–15,01%) dan kadar abu (0,22–0,37%) relatif lebih tinggi dibandingkan pati alaminya, namun perlakuan asam menurunkan kadar amilosa (18,29–27,22%) dan kadar RS (0,06–0,37%). PSIHA memiliki kestabilan yang lebih baik selama pemanasan dengan breakdown viscosity yang lebih kecil dibandingkan dengan PSIA, serta kecenderungan teretrogradasi lebih rendah, yaitu ditunjukkan nilai setback viscosity yang rendah, dan lebih mudah mengalami gelatinisasi.

The purpose of this study was to evaluate the effect of the addition of several glycerol concentrations in the making of edible film from native and phosphate sago starch on physical, mechanical and barrier properties of the film. A completely randomized experimental design was applied in this study consisting of two factors of treatments, i.e.: native and phosphate sago starch, and the second factor was glycerol concentration with three levels of treatments, i.e.: 0.5, 1.0, and 1.5 % (w/w). The films were characterized for tensile strength, elongation, solubility, transparency, and water vapor transmission rate. Edible films have produced characteristics for tensile strength from 3.05 to 31.49 MPa, elongation from 3.03 to 20.94 %, solubility from 33.44 to 42.43 %, transparency from 0.59 to 4.14 %, and water vapour transmission rate from 7.76 to 15.80 g/m2.h. Glycerol was found to affect the increase of elongation, solubility, and water vapour transmission rate, as well as the decrease of its tensile strength and transparancy. The films made from sago starch phosphate showed to increase the solubility and to have significant effect compared with native sago starch, but not affecting the other properties. ABSTRAKTujuan penelitian ini adalah untuk mempelajari pengaruh penambahan beberapa konsentrasi gliserol pada pembuatan edible film dari pati sagu alami dan pati sagu fosfat terhadap sifat fisik, mekanik dan barrier film. Rancangan yang digunakan adalah rancangan acak lengkap yang terdiri dari dua faktor yaitu perlakuan jenis pati sagu dengan dua taraf perlakuan yaitu: pati sagu alami dan pati sagu fosfat dan tiga taraf konsentrasi gliserol yaitu: 0,5, 1,0 dan 1,5 % (b/b). Peubah yang diamati adalah tensile strength¸ elongasi, daya larut, transparansi, dan laju transmisi uap air. Karakteristik edible film yang dihasilkan meliputi tensile strength adalah 3,05 - 31,49 MPa, elongasi 3,03 - 20,94 %, daya larut 33,44 - 42,43 %, transparansi 0,59 - 4,14 %, dan laju transmisi uap air 7,76 - 15,80 g/m2.jam. Penambahan gliserol menyebabkan elongasi, daya larut, dan laju transmisi uap air meningkat, tetapi tensile strength dan transparansinya menurun. Perlakuan pati sagu fosfat hanya menyebabkan daya larut film meningkat, tetapi tidak untuk sifat-sifat film lainnya.
