The antioxidant activity of cookies prepared by the addition of sugarbeet dietary fibers was investigated in order to estimate their influence on functional characteristics and shelf-life of cookies. Treated fiber (TF) was obtained from sugarbeet by extraction with sulfurous acid (75 °C at pH = 5.7during 60 min) and treatment with hydrogen peroxide (20 g/LH2O2 at pH = 11 during 24 h). The fiber obtained was dried (80 °C), ground and sieved. TF was investigated in comparison with commercially available Fibrex®. The cookies were prepared by the addition of 0, 7, 9 and 11% of sugarbeet dietary fiber as a substitute for wheat flour in the formulation of cookies. The antioxidant properties of cookies were tested every 7 days using a DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity test during 6 weeks of storage at room temperature (23 ± 1 ºC). The obtained results indicated that substitution of wheat flour with Fibrex® in the formulation of cookies upgraded the antioxidant activity, i.e. the functional characteristics of Fibrex®-enriched cookies and could prolong their shelf-life. In contrast, TF did not increase the antioxidant activity of TF-enriched cookies. The better antioxidant activities of Fibrex®-enriched cookies could be attributed to the presence of ferulic acid.

Jackfruit has a short shelf life, can only last between 2-3 days at room temperature. Several ways can be done to maintain the shelf life of jackfruits, such as storage in the cold room, pressurized space, or modification of the atmosphere of the room. But this method requires expensive operational costs. The purpose of this study was to examine the effect of using aloe vera gel as an edible coating to be applied to the jackfruit. The study was conducted with the stages of making aloe vera gel as an edible coating, coating the edible coating on the sample, then the sample was stored at 10 and 29oC for 10 days. The research parameters observed were water content, texture, and color. The results showed that the water content of jackfruit could be maintained using an edible coating. The shelf life of jackfruit was longer stored at 10oC than stored at 29oC. The best edible coating results obtained on the treatment of aloe vera gel with a concentration of 0.5% CMC because it can inhibit the increase in water content, maintain texture, and the color of jackfruit is still like fresh fruit. To improve the results of this study, it is necessary to conduct further research by examining the effect of aloe vera gel on the taste and aroma of jackfruit.

Jenang, or what is often called dodol, slab, or gelamai, includes dense, chewy, half-processed products. Jenang, which was innovated from chayote, has a relatively short shelf life, which is only able to survive 3-5 days at room temperature (27ºC). Therefore, a good packaging is needed that can extend the shelf life of one of them is edible coating, which is the packaging of edible materials. Edible coating is one of the efforts that can be done to maintain the quality of a food. The purpose of this study was to determine the quality and estimation of chayote with and without edible jenang based on physical, chemical, and microbiological parameters. In this study using the analysis of water content, peroxide numbers, and total microbes and using the edible dip method. From the research it can be seen that the chayote jenang based on physical quality in edible samples can maintain the water content so that the texture remains elastic compared to without edible until the 15th day. Based on the chemical quality in jenang squash with edible, oxidation only occurred after storage on the 22nd day. Microbiological quality in the conjoined pumpkin jenang coated with edible or without edible was overgrown with a total amount of yeast mold ≥300,000 Cfu / g.
