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.

Tongka langit banana is one of the particular indigenous fruits in Maluku. Tongka langit banana contain high nutrients including pro vitamin A and has a lot of health benefits. However, it is also a perishable product, and would deteriorate if not processed or not completely consumed. Therefore, this banana should be processed into diverse products. It can be processed into intermediate product such as flour, which can be further applied in crackers making. Variables observed on crackers including taste, aroma, colour, texture and overall likeness. Results showed that crackers made from 40% banana flour and 60% wheat flour were mostly liked by panelists in terms of taste, colour, aroma, texture and overall likeness.
