Abstract

Minimally processed fruits provide convenience and freshness characters. Weight loss is a critical factor affecting the shelf life of minimally processed apples. These apples were limited by brown coloration that develops on surface. The objective of this study is to evaluate the effectiveness of edible coat and film made from aren starch against weight loss and browning on minimally processed apples. Edible coat and film solutions were prepared from 3% (w/v) aren starch, 6% (w/w) palmitic acid, and 1% (w/v) sorbitol. Minimally processed apples were either dipped in the coating solution or wrapping by edible film and then stored at ambient temperature for 8 hours. Browning appearance was determined every 4 hours and weight loss of apples was measured every hour.  Edible film was much effective on weight loss control than coating during storage. Color analysis showed that pati aren edible  coating and film wrapping did not significantly delayed browning reaction on  minimally processed apples.

Abstract

Pencegahan penyakit ternyata tidak terlepas dari diet beberapa makanan. Diet makanan yang kaya akan manfaat, seperti buah, sayur, dan biji-bijian telah diyakini berhubungan erat dengan pencegahan penyakit tertentu. Beberapa senyawa fitokimia yang terdapat dalam bahan makanan mempunyai aktivitas biologis dalam pencegahan penyakit, seperti kanker dan jantung. Buku PHYTOCHEMICALS AS BIOACTIVE AGENTS yang ditulis oleh Bidlack et al., ini menyuguhkan tentang aneka ragam senyawa organik yang dibentuk oleh tumbuhan, termasuk cara identifikasi dan evaluasi bioaktivitas fitokimia yang berperan dalam pencegahan penyakit tertentu.

Abstract

This research was carried out in order to reveal ganyong starch’s potential as a major ingredient of edible film, to understand the optimum concentration of ganyong starch and palmitic acid in the making process of edible film and to study their physical and chemical characteristics. The research has two stages, which were the starch preparation, and edible film preparation by using various concentrations of ganyong starch (1, 2, 3, and 4 % w/v) and palmitic acid (1, 2, 3, and 4% w/w). First research stage revealed that ganyong starch has a potential as a major ingredient of edible film because of its high amylose content (32.53% on dry basis). The next stage of the research showed that the optimum ganyong starch concentration of edible film was 2% (w/v). This concentration gives the WVTR (Water Vapor Transmission Rate) measurement of 11.86 (g. mm/m2. hour), film elongation of 2.26%, tensile strength of 3.29 Kpa, and film thickness of 0.0754 mm. The optimum concentration of palmitic acid was 4% (w/v). This results in the WVTR (Water Vapor Transmission Rate) measurement of 7.99 (g. mm/m2. hour), film elongation of 1.24%, tensile strength of 3.58 Kpa, and film thickness of 0.087 mm.
