Roti manis dianalisis secara fisik (tekstur dan porositas) dan kimia (kadar air, kadar abu, kadar lemak, kadar protein, dan kandungan karbohidrat), dan analisis umur simpan dengan FFA, uji organoleptik dan jamur setiap dua hari selama delapan hari penyimpanan di suhu ruang. Variasi perlakuan roti manis adalah dari rasio konsentrasi VCO: margarin: mentega, K (0%: 8%: 8%); A (4%: 6%: 6%); B (8%: 4%: 4%), C (12%: 2%: 2%); D (16%: 0%: 0%). Hasil penelitian menunjukkan bahwa VCO tidak memiliki pengaruh yang signifikan terhadap karakteristik fisik dan karakteristik kimia roti manis. Namun, VCO berpengaruh signifikan terhadap kadar air roti manis yang dihasilkan, roti manis K memiliki kadar air tertinggi (22,36%) dan berbeda dengan sampel roti manis lainnya. VCO secara efektif menghambat pertumbuhan jamur di roti manis pada konsentrasi 8%, 12%, dan 16%.

So that VCO can provide a preservative effect on food ingredients, one of which is sweet bread. This research was conducted to evaluate the effect of VCO on characteristics (physical and chemical) and shelf life of sweet bread. Sweet bread was analyzed physically (texture and porosity) and chemistry (moisture content, ash content, fat content, protein content, and carbohydrate content), and shelf life analysis with FFA, organoleptic and mold tests every two days for eight days of storage at ambient temperature. Treatment variations of sweet breads is from the ratio of the concentration of VCO: margarine: butter, K (0%: 8%: 8%); A (4%: 6%: 6%); B (8%: 4%: 4%), C (12%: 2%: 2%); D (16%: 0%: 0%). The results showed that VCO did not have a significant effect on the physical characteristics and chemical characteristics of sweet bread. However, the VCO has a significant effect on the water content of the sweet bread produced, sweet bread K has the highest moisture content (22,36%) and it is different from other sweet bread samples. VCO effectively inhibits the growth of sweet bread mold at concentrations of 8%, 12%, and 16%.

The use of mocaf is intended as one of food diversification. One of the important steps in making bread is proofing. Proofing is the time needed for the mixture to expand, which can be done by covering with plastic or by providing water vapor in the resting shelves.Preliminary research has been carried out on the length of proofing time (10, 15 and 20 minute), which was needed until the bread can expand perfectly. From preliminary research it was found that the optimum proofing was carried out for 20 minutes. This research was conducted using a randomized complete design with 2 factors,  first factor was  the  use of  mocaf flour with ratio of 10: 20 and 30 precent, second factor was proofing treatment, that was using water vapor method and using covering plastic method.Mocaf bread produced  was tested for color, taste, texture and overall preference for bread both using panelists and using equipment. Data obtained was analyzed using analysis of variances with significance of 5%.

This research aimed to determine the effect of the addition of beeswax emulsion and zinc oxide nanoparticles (ZnO-NPs) on the physical and mechanical properties of chitosan based films. The film was prepared by dissolving ZnO-NPs (0, 1 and 2% by weight of chitosan) into 100 mL of distilled water followed by the addition 1 g of chitosan and or, addition of beeswax emulsion (0 and 5% by the volume of solution). The result showed that the addition of beeswax emulsion ZnO-NPs into chitosan based film significantly decreased WVTR value from 24.03 to 10.38 g/m2 hours and the  tensile strength value from 8.30 to 6.92 Mpa. The addition of beeswax emulsion and ZnO-NPs also changed the physical properties of chitosan-based film significantly; in terms appearance, color and thickness.

The water extract was prepared by the infusion method, while the essential oil was made by steam and water distillation. The phyto-chemicals composition of the water extract and essential oil was analyzed by qualitative colorimetric phyto-chemical screening and Gas Chromatography-Mass Spectroscopy (GC-MS) technique, respectively.

Germination was performed at four levels of incubation time (0, 48, 72, and 96 hours) at room temperature in the dark room and two levels of blanching time (0 and 30 second). The functional properties analyzed consisted of bulk density, flour solubility, water and oil absorption, and capacity and stability of emulsion.

Blanching decreased the functional properties of the flour. The statistical analysis showed that there was no significant interaction between two factors in all parameters.
