Abstract

This experiment aims to the observed morphology, reduction of fineness and distribution particle deterioration of W/O/W double emulsion in instant noodle seasonings which is kept in 3 weeks with different storage temperature and NaCl level treatments. Emulsion structure has an important role to hamper salt release rate from internal to external phase. Structure breakdown shows system inability to maintain continuous salty taste perception during consumption because of the increasing salt release rate in storage period of instant noodle seasoning. Samples are treated with 3 variations of storage temperatures which are low (4 °C), room (25 °C), high temperature (40 °C) and 6 variations of NaCl level which are 0; 0,2; 0,4; 0,6; 0,8; 1%. Samples are categorized into 2 groups, double emulsions, and instant noodle seasonings. The double emulsion is made by 2 phases emulsification to get primary W/O emulsion and final W/O/W emulsion. This experiment showed that low and high-temperature storage affected emulsion and seasoning particle morphology, fineness and distribution throughout several instability phenomena.

Abstract

Edible film is a potential biodegradable packaging in the food industry. This research is aimed to determine the physical, chemical and mechanical properties of Aloe vera with extra virgin olive oil and chitosan emulsion edible film. Complete Randomized Design was used with five treatments and four repetitions. The treatments were composition ratio between Aloe vera gel and extra virgin olive oil (EVOO) - chitosan emulsion that consists of T1 (40:60), T2 (45:55), T3 (50:50), T4 (55:45) and T5 (60:40). The method used in this study included making Aloe vera gel and an emulsion of EVOO 1% (v/v) in chitosan 1% (b/v), homogenizing the materials, casting and drying. The results showed that range of film thickness, solubility, water vapor permeability, antioxidant activity, extension and tensile strength were 0.067-0.073 mm, solubility 48.70-65.73%, 1.39 × 10-5 – 1.77 × 10-5 g mmHg-1 m-1 h-1, 3.31-6.56%, 6.78-14.72% and 0.29-0.68 MPa. The edible film composition showed significant difference (p ≤ 0,05) for thickness, solubility, antioxidant activity, extension and tensile strength film, however, the water vapor permeability was not significantly different (p ≥ 0,05).
