Abstract

Buah sukun memiliki kandungan karbohidrat yang tinggi, namun memiliki umur simpan yang pendek dan cepat busuk, maka perlu diolah menjadi tepung yang nantinya dapat diolah lebih lanjut menjadi berbagai produk pangan. Akan tetapi tepung sukun memiliki pengembangan dan pengikatan air rendah sehingga diperlukan modifikasi sehingga dapat diaplikasikan secara luas pada produk pangan salah satunya meat analog. Meat analaog umumnya terbuat dari bahan nabati yang memiliki sifat kurang kompak, kenyal dan cenderung keras sehingga membutuhkan bahan pengikat. Penambahan tepung sukun termodifikasi ini berpotensi sebagai bahan pengikat. Tujuan dari penelitian ini yaitu untuk mengatahui pengaruh perbandingan modifikasi fisik dan kimia terhadap karakteristik fisik tepung serta aplikasinya pada meat analog. Hasil penelitian menunjukkan bahwa modifikasi asetilasi meningkatkan swelling power, WHC, OHC dan menurunkan kelarutan. Modifikasi oksidasi meningkatkan swelling power dan kelarutan akan tetapi menurunkan WHC dan OHC. Modifikasi pregelatinisasi meningkatkan swelling power, kelarutan, WHC akan tetapi menurunkan OHC. Modifikasi Heat moisture treatment meningkatkan kelarutan akan tetapi menurunkan swelling power, WHC dan OHC. Aplikasi tepung sukun termodifikasi pada meat analog cenderung menurunkan nilai L* dan kekerasan, meningkatkan kekenyalan dan kekompakan. Penambahan tepung sukun termodifikasi cenderung meningkatkan sensoris kelengketan, kelunakan dan elastisitas. Kata kunci: meat analog, modifikasi fisik, modifikasi kimia, sukun

Abstract

The cross-linking agent plays an important role in bioplastic mechanical properties. This study aimed to determine the effect of Sodium Hyaluronate (SoHA) as a synthetic cross-linking agent and the addition of Nyamplung Cake Extract (NCE) as an antimicrobial agent in the manufacture of bioplastic with hydroxypropyl starch (HPS) as based ingredient using the thermo-compression method. The novelty of the study was thiocyanate (SCN) formation in zone 3 (2161.66-2162.02/cm) and cyanate (C-N=O) in zone 6 (1,411.57 - 1,412.61/cm) of (1, 2 and 3%) SoHA bioplastic and cyanate formation in zone 6 and 7 (1,411.37 - 1,558.59/cm) of (1, 2 and 3%) SoHA – 20% NCE combined bioplastic originating from acetanilide group in SoHA and amide group in NCE. The formation of SCN and C-N=O in 2 and 3% SoHA bioplastic improved its sensitivity against gram-positive bacteria (Staphylococcus aureus) indicated by 0.6 mm and 0.45 mm inhibition zone, respectively. C-N=O formed in (1, 2 and 3%) SoHA – 20% NCE combined with bioplastic had 3.25 mm average inhibition zone against gram-positive bacteria (S. aureus), 2.75 mm against gram-negative bacteria (Escherichia coli), and 0.71 mm against fungi (Aspergillus niger). The analysis of mechanical properties showed that an addition of 3% SoHA was able to increase tensile strength and modulus of elasticity while reducing elongation, water solubility and water vapor permeability. Addition of (1, 2 and 3%) SoHA – 20% NCE resulted in a reverse effect.

Abstract

Pears (Pyrus pyrifolia) are tropical fruits with a sweet taste, crisp texture, and high water content. Cut pears have a short shelf life of 3-5 days due to enzymatic browning and physical damage after cutting. One method to extend shelf life is the use of edible coatings. This study aimed to test the effectiveness of sodium alginate and calcium chloride as coatings for cut pears in maintaining physical quality and extending shelf life. This study used a completely randomized design (CRD) with two factors: the first factor was sodium alginate concentration and the second factor was calcium chloride concentration. Pear coating was carried out by making a solution of sodium alginate and calcium chloride with concentrations of 1% and 2%, respectively. The coating process was carried out using the dipping method. The pears were washed and then peeled. The samples were then dipped in a sodium alginate solution for 2 minutes, and then dipped in a calcium chloride solution for 1 minute. Then the pears were stored at 4 Celcius degree and tested for 0, 6, and 12 days. Based on the results of the study, it showed that coating using sodium alginate and calcium chloride was able to suppress the increase in weight loss, total soluble solids, and maintain the color value of the pears. At a concentration of 2% sodium alginate and 1% calcium chloride, it had an effect on slowing down the decline in pear quality during storage.
