Abstract. Chutney is a native Indian processed product, made from cuts of fruits or vegetables and nuts cooked in a sweet, sour and spice mixture. The quality requirements of chutney are influenced by the use of raw materials herbs and spices. The purpose of this study was to determine the response of three varieties of mango and its interaction with concentration of apple vinegar towards physicochemical characteristics of mango chutney. The experimental design of this study used a nested design with two factors. The first factor was three varieties of mango consisting of podang mango, gadung, and kweni and the second factor was the concentration of apple vinegar (5%: 10%: 15%).Parameters analyzed were moisture content, ash content, vitamin C, total soluble solids, total titrated acids, pH, crude fiber, antioxidant activity, color intensity, topicality and hedonic test (flavor, aroma, and appearance). The study showed that differences in mango varieties and apple vinegar concentration did not interact with moisture content, ash content, total soluble solids, total titrated acids, vitamin C, crude fiber, antioxidant activity, pH, color intensity, topicality and hedonic test. The differences in mango varieties significantly affected on water content, color intensity (L and a+), topicality, and hedonic test, whereas the difference of apple vinegar concentration had no significant effect on ash content, pH, total soluble solids, total titrated acids, vitamin C, crude fiber, and antioxidant activity.

Abstract

Abstract.Currently ethanol produced from molasses, cassava and maize, thereby competing with the need for food, animals feed and other industrial raw materials, so that the supply of raw materials is not continuity. If this continues, it will certainly have an impact on food prices spike, it will create new problems on the economy of the community, and one of an alternative raw material for bioethanol production is cellulose biomass.To convert biomass into bioethanol through several stages, including pretreatment, hydrolysis and fermentation. The content of lignin in biomass will disturb the enzymatic hydrolysis process, so it is necessary to encourage the delignification in the pretreatment stage. Microwave - alkali pretreatment can reduce more lignin and hemicellulose in rice straw, so it needs to be an effort to change the composition of lignocellulose and improve the hydrolysis of corn cob is fermented to become ethanol. Pretreatment of corn cobs research was done using randomized block design arranged in factorial and repeated 2 times. The first factor is the concentration of NaOH for 0,5 N, 1 N and 1,5N. The second factor is the time of exposure to microwave heat radiation for 10, 20 and 30 minutes. The results showed that cellulose content increases with prolonged exposure concentrations of NaOH and microwave, as well as to the content of hemicellulose and lignin decreased along with the increase of exposure duration of Microwave and the increase of NaOH concentrations.

Abstract

Abstract.Edible film is a thin layer to protect food which it can be consumed. One of the main components to make edible film is starch, which could be derived from taro tubers. Taro tubers contain high starch content about 70-80% which consists of 5.55%  of amylose and 74.45% of amylopectin with yield reach to 28.7%. However, the weakness of starch-based edible film are low resistance to water and low barrier properties to water vapor. One of the recommended hydrophobic biopolymers to improve the film characteristics of starch as well having antimicrobial activity is chitosan. The objectives of this research are to know the interaction and influence of starch concentration from taro tuber and concentration of chitosan on physical and mechanical character of edible film, including thickness, density, transparency, tensile, elongation and water vapor transmission eate (WVTR). The best treatment from  first objective will apply on dodol (food made by glutinous rice) substituted by seaweed to know the effect of its application on dodol shelf life (texture analysis, weight loss and microbiology). Therefore this research was conducted in 2 stages and 2 experimental design methods. The first stage was the process of making edible film using Randomized Block Design method and the second stage was the application of edible film using Random Design Complete method. The results of physical and mechanical analysis of edible film based on its effect on the storage of dodol showed that the best treatment was obtained of P3K3 treatment (6% of Taro starch: 3% of Chitosan), P3K1 (6% of Taro starch: 1% of Chitosan) and P3K2 (6% Taro starch: 2% of Chitosan). The application of 3 types of edible films based on the best treatment of dodol substitute of seaweed  has significant effects on the value of weight loss, texture and total plate count during the storage period. Effectiveness of edible film in inhibiting damage to dodol was obtained of P3K3 treatment (6% of Taro starch: 3% of Chitosan) with WVTR value equal to 0.189 g / cm2 hour, 0.170 N / mm2 of tensile strength, 0.088% of elongation, 0.160 mm of thickness, 0.151 of density and 0.000 mm-1of transparency.

Abstract

Cooking oil is a necessity of the people of Indonesia that is always needed. Based on the stages of manufacture, oil is divided into two, namely branded oil and bulk oil. Until now, branded oil is still the main choice even though it is economically more expensive than bulk oil. This is related to the tendency of bulk oil to experience rancidity due to oxidation reactions. The quality of bulk oil can be scientifically improved by the addition of antioxidants. Commonly used antioxidants are synthetic antioxidants such as TBHQ. Natural antioxidants are less popular because they have only stalled in the study but have not been compared significantly with synthetic antioxidants. In this study, a research is used to find out the stability of bulk oil with the addition of bay leaf ethyl acetate fraction and as a comparison of the use of TBHQ. Analysis of antioxidant activity of DPPH method was also used to find out determine the relationship between the power of antioxidant activity with the quality of bulk cooking oil. The evaluation was performed on the addition of bay leaf extract with various concentrations treated on bulk oil by heating for 20 minutes using 90ËšC temperature. The results showed that the bay leave ethyl acetate fraction has IC50 value of 19.473 ppm, so it can effectively reduce the number of peroxide. The smallest peroxide number was obtained at treatment P6 (1%) that is 5,304 meqO2 / kg, where TBHQ (0,2%) as comparison have value equal to 4,147 meqO2 / kg. This shows that the antioxidant activity is very strong in bay leaf significantly affect the inhibition of bulk oil destruction. Natural antioxidant from bay leaf can prevent bulk oil from oxidation as well as synthetic antioxidants, but safer than synthetic antioxidants.

Abstract

Bakso daging sapi merupakan lumatan daging sapi yang mudah mengalami kerusakan. Berdasarkan data yang dihimpun oleh BPOM pada tahun 2005 bahwa bahan tambahan pangan yang paling sering di gunakan untuk bakso adalah boraks dan formalin. Mengingat bahaya boraks dan formalin apabila dikonsumsi, maka perlu dilakukan penelitian mengenai metode pengawetan bakso secara aman yaitu pelapisan edible coating dengan penambahan oleoresin dari rimpang jahe sebagai senyawa antibakteri. Penelitian ini bertujuan untuk mengetahui apakah pemberian edible coating dapat meningkatkan umur simpan bakso daging sapi pada penyimpanan suhu ruang. Penelitian ini bersifat eksperimen di laboratorium dengan rancangan acak lengkap sederhana dengan faktor penelitian yaitu konsentrasi oleoresin dari rimpang jahe emprit yang terdiri dari lima level yaitu 0%, 0,5 %, 1 %, 1,5 %, dan 2 % dengan 3 kali pengulangan. Umur simpan bakso daging sapi dilihat melalui TPC, pH, kadar air, kadar protein, susut bobot dan uji tekstur. Data penelitian dianalisis ANOVA dan uji lanjut menggunakan uji Duncan (DMRT). Bakso berpelapis edible coating berbasis pati jahe dengan dengan penambahan 2% oleoresin dan penyimpanan suhu ruang menghasilkan umur simpan 48 jam, sementara bakso tanpa pelapis (kontrol) hanya bertahan 24 jam. Perlakuan oleoresin sebanyak 2% berpengaruh nyata (p<0,05) terhadap karakteristik bakso dengan nilai TPC yaitu 7,3 x107 cfu/g, nilai kadar air 69,62 %, susut bobot 0,172 %, kadar protein 5,08 %, pH sebesar 6,050 dan tekstur 0,030 N/m2.
