Abstract

Pineapple is a perishable agricultural products, therefore it needs an appropriate treatments at the postharvest stage. An appropriate treatment will contribute on maintaining the quality and prolong shelf life of the products. Recently, several efforts have been conducted to achieve the purposes. Moreover, appropriate treatments are still required for alternatives solution of pineapples producers. This study aims to determine the effect of the dipping on CaCl2 solution at various concentration on physical (mold incidence and mold severity), chemical (pH value) and sensory properties (color, texture, aroma, taste, and overall acceptance) of pineapple during storage. The dipping of the fruits were conducted at hot condition (50℃). The samples were MD-2 pineapple with two different classification of shell color (shell color 0 and shell color 2). The results showed that there was no significant effect of CaCl2 application treatment by dipping in hot water (50℃) on the parameters of pH value. The incidence and severity of mold were detected after 16th of storage on treated samples and the control. After storage for 40th days, the treated sample had better sensory properties, particularly on texture, color, and overall acceptance.

Abstract

The edible film aims to improve the shelf life and safety of food by providing a physical barrier to external influences to prevent food deterioration. Arrowroot starch has high amylose content and excellent gelling ability, and it is massively produced in Indonesia. At the same time, glycerol has water-soluble and polar properties. So, studies were carried out on edible film based on arrowroot starch as the polysaccharide and glycerol as the plasticizer. This study was contributed to investigate the effect of the concentration of arrowroot starch (3, 4% w/v) and glycerol (1.25, 1.5, and 1.75% w/v) on physical properties (thickness by micrometer, functional group by FTIR, molecular structure surface by SEM) of edible film. The results showed that increasing the concentration of arrowroot starch and glycerol could increase tensile strength. Besides that, the formulations of 30% arrowroot starch with 12.5% glycerol and 40% arrowroot starch with 17.5% glycerol had the best tensile strength of 27.24 and 22.88 MPa, respectively. However, the results of the morphological analysis of the edible film on the arrowroot starch-glycerol formulation still contained pores and cracks.

Abstract

Tujuan penelitian ini adalah mengkaji pengaruh konsentrasi gliserol terhadap karakteristik fisik dan kimia dari Edible film yang dihasilkan berbasis pati garut serta mengkaji pengaruh bahan pati garut terhadap karakteristik fisik dan kimia dari Edible film yang dihasilkan. Penelitian ini menggunakan metode rancangan percobaan Rancangan Acak Lengkap dengan 6 kombinasi perlakuan dan 3 kali ulangan. Perlakuan yang digunakan adalah jumlah pati garut 3 gram dan 4 gram serta konsentrasi gliserol 1,25%, 1,5%, 1,75%. Kesimpulan pada penelitian adalah hasil dari analisis kadar air, ketebalan, kelarutan dan warna (a,b) menunjukkan tidak ada perbedaan yang signifikan dengan menggunakan uji F pada taraf 5% kecuali parameter warna kecerahan (L) dengan kadar pati yang berbeda menunjukkan adanya pengaruh atau perbedaan yang signifikan tetapi tidak ada pengaruh ataupun perbedaan yang signifikan antara perbedaan konsentrasinya.
