Abstract

This study examined the characteristics of the edible film mixture gelatin bovine split hide and soy protein isolate, cross-linked using transglutaminase enzyme with addition level of glycerol as a plasticizer.The material used gelatin  combination (Gelatin bovine split hide: soy proteinisolate = 90: 10 with 30 Utransglutaminase enzyme levels ), and glycerol. Data were analyzed  using completely randomized design each treatment was replicated thrice of glycerol as a treatment level ( 10%, 20% dan 30%). The results showed that the glycerol level significantly affected the thickness, elongation, solubility, degree of cross-linking and WVTR, but not the tensile strength.The addition of glycerol causing the film becomes more elastic and  the surface is more homogeneous and compact. Increasing the level to 30% glycerol affects the mechanical properties of an edible film.

Abstract

Low daily calcium intake in Asia, especially in Indonesia, is still a serious problem. The abundant fish bone waste from the fishery fillet industries in Indonesia,  can be employed as an alternative source of calcium to meet daily calcium needs. This research aimed to determine which of the six fish species (tilapia, catfish, grouper, snapper, tuna, kingfish mackerel) produces the best quality and the most cost-effective nano-calcium powder for a recommendation to the stakeholders. The calcium was extracted using an alkali treatment. The properties of the produced nano-calcium powders were analyzed for: proximate composition, calcium and phosphorus levels, color brightness level, XRD, FTIR, particle size, and SEM-EDX image analysis. The tilapia bone had the finest particle size of calcium (87.37 nm), while the grouper bone had the biggest particle size (281.4 nm). The brightness of all yields varied from 83.83 (beige-kingfish mackerel) to 90.64 (white-tilapia). The average calcium content from EDX analysis varied from 21.51% (snapper) to 34.37% (grouper). The average phosphorus levels ranged from 10.73% (kingfish mackerel) to 15.99% (grouper). The EDX Ca/P molar ratio was 1.41-1.66 across all samples. The FTIR spectra showed that all samples contained PO, CH, CO, NH, and OH groups. The XRD spectra pattern determined that the two main components of the fish bone nano-calcium powder were 90% hydroxyapatite and halite. All fish bone samples have the potential to be used as raw material for nano-sized calcium. However, grouper bone with the highest calcium content and the highest nano-calcium yield was the best choice for further study.

Abstract

Fish skin was a raw material for gelatin extracted. Fish skin drying was effectto physico-chemical of gelatin. Fresh fish skin and dry fish skin was compare tostudied gelatin extracted. Swamp ell skin and catfish skin was compare too. Swampell skin doesn’t have scales, with much mucus and a few fat for catfish, it’s different from another fish skin that gelatin extracted usually The first stage of the research was raw material preparation (fresh and dryfish skin) soaked in aquadest for 4 hours. Fish skin extracted using 0,05 M aceticacid for 10 hours, washed in water and then extracted using aquadest at 80oC for 2 hours to get gelatin liquid, the liquid was filtrated. Filtrat was dried in cabinet dryer at 55oC for 48 hours to get gelatin layers, and then blended to get gelatin granule.The results were showing viscosity of gelatin from dry fish skin as same asfrom fresh fish skin, gel strength and melting point of gelatin from dry fish skin washigher than from fresh fish skin. Influence of fish skin drying was increase turbidity and color of gelatin. The best gelatin was ekstracted from dry skin swamp ell withviscosity 6,65 cps, gel strength 206,30 Bloom, melting point 22,33oC. Gelatin fromfresh skin swamp ell was the best turbidity 1,65 ntu and color (L = 41,87, a = 8,90, b= 27,27).

Abstract

Skin of swam ell and catfish were potential to gelatin extracted. Swamp ell skin doesn’t have scales, with much mucus and a few fat for catfish, it’s different from another fish skin that gelatin extracted usually. This research was studied yield and proximate gelatin extracted from skin of swam ell and catfish. Influence of drying was observed too.The first stage of the research was raw material preparation (fresh and dryfish skin) soaked in aquadest for 4 hours. Fish skin extracted using 0,05 M aceticacid for 10 hours, washed in water and then extracted using aquadest at 80oC for 2 hours to get gelatin liquid, the liquid was filtrated. Filtrat was dried in cabinet dryerat 55oC for 48 hours to get gelatin layers, and then blended to get gelatin granule.The results were gelatin yield from dry fish skin lower than fresh fish skin. Gelatin protein from dry fish skin more higher than fresh skin. Influence of fish skin drying was decrease gelatin ash and fat, but gelatin moisture wasn’t influenced. Gelatin from fresh skin swamp ell was the best gelatin with moisture 9,91%, ash 3,07%,protein 91,61%, lipid 0,82%.

Abstract

Cassava starch is one of the processed products of cassava, which can be made into maltodextrin. Maltodextrin is often applied to the encapsulation method of instant drink packaging in Indonesia. One of the most favorite fruits in the instant drink industry is red guava. The research objectives are to know the characteristic of maltodextrin made by hydrolysis of cassava starch, and to identify the effects of the amount of maltodextrin added to the characteristic of red guava extract produced. In the research, the hydrolysis time of cassava starch is varied into 60, 90, and 120 minutes. Maltodextrin made will be analyzed, and its characteristics on the encapsulation of red guava extract will be defined. The red guava juice is encapsulated by the variants of maltodextrin concentration as 10%, 15%, 20%, and 25%. Red guava extract powder produced from the selected amount of maltodextrin then be analyzed for its characteristics. The results showed that the highest DE was found in maltodextrin with 120 minutes hydrolysis time. The increased amount of maltodextrin added affects the increase of solubility and vitamin C levels of the produced red guava juice extract. The water content is not affected by the amount of maltodextrin added.

Abstract

The utilization of native cassava starch in the food industry is limited. It needs a modified process to increase its utilization. This study aimed to evaluate the effect of a combination of steaming and acid hydrolysis and determine the best temperature and hydrolysis time that is suitable to apply as an encapsulant in the nanoencapsulation process of cocoa leaf crude extract. Modification of cassava starch used 50 ℃, 60 ℃, and 70 ℃ temperatures for 30, 60, and 90 minutes with HCl pH 1. The result showed that modified cassava starch produced from a combination of steaming and acid hydrolysis at 70℃ for 30 minutes has the best specifications with 60.48% solubility, 12.38% hygroscopicity, pasting profile (PV=48; BV=3; FV=66; SV=21). Then, it is combined with Arabic gum and used in the nanoencapsulation process using spray drying. This study showed that encapsulation can protect phenolic compounds of cocoa leaf crude extract resulting brownish-red color surrounded by a black circle. Nanocapsule powder has 13.56% moisture content, 350.3 nm particle size, 16.93 zeta potential, and 84.30% encapsulation efficiency. The combination of steaming and acid hydrolysis at 70 ℃ for 30 minutes produces modified cassava starch which is suitable for use as an encapsulant in the nanoencapsulation process of crude extract of cocoa leaves.
