Abstract
The edible coating is biodegradable and sustainable packaging has come into attention since the past few decades as an effort to reduce packaging waste. On a landmark fruit, the edible application layer is used to reduce the occurrence of loss of moisture, improve appearance, acts as a barrier to the exchange of gases, as well as having functions as an antifungal and antimicrobial. In addition to extending shelf life can be eaten these many layers are used such as it does not endanger human health, can be eaten as well as easy to untangle nature. One of the natural ingredients that can be used such as a layer of edible is Aloe Vera. From the results obtained that the weight without warming treatment gel stored at cool temperatures is relatively constant, while to gel without or with the treatment of warming that is stored at room temperature a little decline. The reduction drastic invisible on the gel with the saved warming treatment in cold temperatures. Aloe gel good shaped pieces that are stored at room temperature has decreased the weight but that is stored on the cold temperatures are relatively stable. The aloe vera gel with warming and stored at cool temperatures until day 5 relatively stable, as seen from the variable weight shrinkage, color, pH, viscosity, and moisture content. While the gel is stored at room temperature decrease began day 2. Aloe Vera gel should be stored at cool temperatures with a sealed container. The best characteristics of Aloe Vera gel that treatment with sorbitol can extend the shelf life strawberry fruit. edible coating base on Aloe gel can be applied at post-harvest handling fruits.
Highlights
Strawberry fruits are a source of vitamins, minerals, and fiber that has nutritional benefits which are very good for health
This research aims to study the characteristics of the Aloe Vera gel as edible coatings in terms of the type and concentration of the addition of fillers, that will be applied to the handling of post-harvest fruit strawberry so have time to save
3.1 Edible coating base on Aloe Gel Aloe Vera gel without the warming that is stored at room temperature on day 3 is already
Summary
Strawberry fruits are a source of vitamins, minerals, and fiber that has nutritional benefits which are very good for health. Public awareness of the importance of health and nutritional value of the food they consume that stimulated. This increase from a demand for high-quality fruit, i.e. have a good appearance, relatively durable, and not quickly wither and rot during storage. Edible coating very potential to increase the shelf life of fruits due to the theoretical development edible coating will form a coating that is capable of acting as a barrier to prevent moisture loss, are permeable to certain gases, as well as controlling the migration of water-soluble components that could cause pigmentary changes and nutritional components in fruits. Preservatives act as antioxidants, which will suppress the reaction that occurs upon contact with oxygen, food, rays, heat and some metal to prevent the onset of rancidity and the emergence of black smudges on the food products
