| description | Hibiscus rosa-sinensis is a common found plant which leaves arewell
known to contain a polysaccharide biopolymer in the form of mucus. Polysaccharide
biopolymer is one of component in the manufacture of edible film. Until now, there
has been no research on edible biopolymer films from hibiscus leaves. The purpose of
this study is to identify the chemical characteristics of (moisture content, ash,
methoxyl, proteins, fats and carbohydrates), physical characteristics such as
(thickness, tensile strength (tensile strength), elongation (elongation), solubility) and
barrier properties (water vapor permeability) edible film produced by isolat
biopolymer hibiscus leaves with the addition of sorbitol as a plasticizer. For the
making process of biopolymer from hibiscus leaf, it needs to extract the hibiscus leaf
by using water, then carried precipitation with ethanol 96%, and continued with
drying, and milling. Edible films which made in this study are using a vary
concentration of biopolymers isolates 1%, 1.25%, and 1.5% w / v, with a fixed
concentration of plasticizer sorbitol, which is 30% w / w isolates biopolymers. The
results showed that the yield of isolates biopolymers hibiscus leaf is at 4.17% (w / w).
Isolates biopolymer contains 5.11% methoxyl, 11.70% ash, 9.13% moisture, 18.99%
protein, 0.96% fat, and carbohydrate (by difference) of 58.68%.In the reducing
sugar test showed no detection of biopolymers isolates indicated by the absence of
sediment and discoloration. The physical characteristics and barrier properties of
edible film show that the higher the concentration of biopolymers isolates will
increase the thickness, solubility and tensile strength, but decrease elongation and
permeability to water vapor. At the highest concentration of biopolymers isolates
were being used, ie 1.5% (w / v), the edible film has 0.09 mm thickness, tensile
strength of 4.82 MPa, 73, 80% solubility, 0, 09% elongation , and water vapor
permeability 17,43 g.mm/m2 day kPa. |
