Abstract

Nugget is favorite fast food, which contain a high cholesterol and low in minerals such as calcium. Chicken eggshell is an idle resource, which contain high calcium. Fortification of calcium sources from chicken eggshell powder is a good innovation to increase the nutritional value of nuggets, and utilizing of idle resources that are currently not properly managed. The purpose of this research was to determine the effect of additional chicken eggshells powder as calcium fortification to the characteristics of nuggets, and percentage of additional chicken eggshell powder to produce the best nuggets. This research was an experimental study using a Completely Randomized Design with the treatment of additional chicken eggshell powder for nuggets. The treatment carried out with five levels of 0%, 5%, 10%, 15%, and 20%, by weight of the nugget raw material. Each treatment was repeated three times. The results of physical, chemical, and organoleptic characteristics analysis showed that the additional of chicken eggshell powder has a significant effected to the water content, ash content, protein content, calcium content, taste, and texture, but did not significant affected the fat content, pH value, hardness level, color, and flavor of the nuggets. Based on the results of the effectiveness test, the best treatment in this research was the addition of 5% chicken eggshell powder. The addition of chicken eggshell powder can significantly increase calcium and ash content of the nuggets, but significantly decrease taste and texture of the nuggets. The addition of 5% chicken eggshell powder produced the best nuggets.

Abstract

Pandanus fruit that is yellow to orange can be used as a food coloring as well as a source of pro vitamin A. Food coloring from pandanus extract is made in powder form for easier use and more stable in storage. The purpose of this research is to determine the best encapsulan type and concentration to produce pandanus fruit color extract encapsulat. The main ingredients of the research are yellow to orange pandanus, acetone, chloroform, maltodextrin, and gum arab. The experiment was a two-factor factorial experiment using randomized block design. The first factor is encapsulation (maltodextrin and gum arab), second factor is concentration of encapsulan solution (10, 20, 30%). Prepared a powder 60 mesh with water content of about 8-10%, then extracted with chloroform acetone solvent (1: 3), at 50 ° C, for 5 hours, resulting in extracts of thick pandanus color. The thick pandanus colorant extract was encapsulated using maltodextrin and gum arab respectively with concentrations of 10, 20, and 30%. The results showed that the best encapsulan type and concentration to produce pandanus fruit extract encapsulat was 10% gum arabic with water content characteristic 9.40 ± 2.01%, solubility 92.57 ± 0.63%, total carotenoid 18.78 ± 1.78 mg / 100g, surface carotenoid 0.04 ± 0.03 mg / 100g, encapsulation efficiency 99.88 ± 0.09%, brightness, redness, and yellowish levels of 28.53, 8.67, and 45.39 respectively.

Abstract

Liquid pulp by-product of fermentation of cocoa beans can be processed into cocoa vinegar. Cocoa vinegar as a new food product needs to be determined its shelf life. The objectives of this study were: (1) to know the stability of cacao vinegar distillate products during storage, and (2) to determine the shelf life of cocoa vinegar distillate using Accelerated Shelf-Life Testing (ASLT) method based on Arrhenius approach for determination of expired period of product. In this study, the storage of cocoa vinegar distillate for 10 weeks at three different temperatures, namely: 28oC, 40oC, and 50oC, and each experiment was done twice repeated. Weekly observations were done on the characteristic parameter of cocoa vinegar distillate. The results obtained show that: (1) during storage there is a decrease in acetic acid concentration, but an increase in pH, TSS and clarity value (OD600) of cocoa vinegar distillate; (2) the determination of shelf life is based on pH characteristics with equation of Ln k = -2217.2 (1/T) + 5.1875, which shelf life at temperatures: 10oC, 20oC, 28oC, 40oC, and 50oC respectively: 35.28 weeks (8.23 months), 27.01 weeks (6.30 months), 22.09 weeks (5.15 months), 16.65 weeks (3.89 months), and 13.37 weeks (3.12 months). The data of shelf life may be used to specify the expiration period, which must be included in the packaging label.

Abstract

One of tropical plant used as a traditional beverage in Bali is Kecemcem or Cemcem (Spondias pinnata (Lf) Kurz) or in Indonesian called Kedondong Hutan. Empirically, the beverage is mentioned for treating coughs, increasing appetite, and body refreshment. Besides used as a beverage, Cemcem leafs are also used as a flavor enhancer of fish products. The study was carried out to determine the characteristics of Cemcem instant powder produced by encapsulation using maltodextrin and dried by the thin layer drying method. Cemcem instant powder was then analyzed its content of vitamin C, total phenols, tannins, antioxidant capacity, water cntent, ash content, and solubility. The flavor compounds in Cemcem instant powder obtained in Bukit Jimbaran area are identified by GC-MS devices. The result showed that cemcem instant powder which was produced by 24 hours of maceration time has the best characteristics and potential to be developed as a natural antioxidant products. It has the highest of total phenol, tannin, vitamin C, and antioxidant capacity. The content of vitamin C, total phenol, and tannin were 135.06 mg/100g, 38.95 mg GAE/g, and 11.01% respectively. The antioxidant activity of cemcem instant powder which analyzed by DPPH method was about 43.80%. There are 17 compounds detected by GC-MS, these compounds belonged alkenesalcoholsphenols compounds and esters of fatty acidsThe whole compounds were the building blocks of flavor cemcem leaves.Keywords : Characteristic of cemcem instant powder, antioxidant capacity, andflavor compounds of cemcem leaves

Abstract

Cemcem leaves (Spondias pinnata (Lf) kurz is one plant that is used as a traditional drink for health benefits. This study was carried out to (1) Influence of Cemcem leaves powder extract to increased antioxidant capacity, enzyme activity of Superoxide Dismutase (SOD) and Malondialdehyde (MDA) levels in the Sprague Dawley (SD) rat liver and (2) determine the best doses to increased antioxidant capacity and enzym activity of SOD and decreas the levels of MDA in the Sprague Dawley (SD) rat liver. Methods used to determination of the effect of Cemcem leaves powder extract on levels of antioxidant capacity, SOD and MDA were performed in SD rat. The dose which was consumed were 50 mg/kg/day, 100 mg/kg/day, 150 mg/kg/day, and 200 mg/kg/day. The results showed that the cemcem leaves powder extract that was consumed orally for seven weeks at a dose of 50 mg / kg / day up to 200 mg / kg / day was able to significantly (P <0.05) decrease the levels of MDA and increase antioxidant capacity and SOD enzyme activity in rat liver. The conclusion of this study is that the extract at a dose of 50 mg / kg / day up to 200 mg / kg bw / day can increase the antioxidant capacity and SOD enzyme activity, as well as decrease the levels of MDA in the Sprague Dawley rat liver and Cemcem leaves powder extract at a dose of 200 mg / kg / day have the same ability by administering Vitamin C 50 mg / kg / day.Keywords : Cemcem Leaf Powder Extract, Maltodextrin, antioxidant capacity, SODand MDA
