Edible Coating Berbasis Pati Sagu dengan Penambahan Antimikroba Minyak Sereh pada Paprika: Preferensi Konsumen dan Mutu Vitamin C

Paprika merupakan salah satu jenis sayuran buah yang memiliki prospek pasar yang cerah dan terbuka lebar baik untuk pasar domestik maupun ekspor. Namun, paprika merupakan sayuran buah yang tidak awet dan mudah rusak (perishable commodity) sehingga paprika memerlukan penanganan pascapanen yang tepat agar dapat meningkatkan masa simpannya. Salah satu teknologi potensial untuk diterapkan pada paprika yaitu pelapisan permukaan paprika dengan bahan edible (dapat dimakan) dan ditambah dengan antimikroba alami untuk menghindari serangan mikroba. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi minyak sereh dan lama perendaman terhadap sifat kimia dan organoleptik (warna, aroma, tekstur dan rasa) paprika merah yang diberi perlakuan edible coating berbasis pati sagu dan antimikroba alami minyak sereh. Selain itu juga dianalisis Perubahan mutu kimia vitamin C pada paprika merah selama penyimpanan. Perlakuan yang diberikan untuk pengujian karakteristik sensori yaitu (a) konsentrasi minyak sereh 0,2% dan 0,4% dan (b) lama pencelupan dalam formula edible coating yaitu 3 dan 5 menit. Paprika lalu disimpan pada suhu 8°C. Sebagai kontrol dilakukan juga pengamatan terhadap paprika yang tidak di coating dan yang di coating namun tanpa menambahkan minyak sereh. Hasil penelitian menunjukkan bahwa perlakuan coating tidak berpengaruh nyata pada penerimaan panelis terhadap atribut aroma, tekstur, rasa maupun penerimaan keseluruhan paprika. Perlakuan coating hanya berpengaruh nyata pada penerimaan panelis terhadap atribut warna paprika merah. Panelis dapat menerima perlakuan coating pada paprika, baik dengan atau tanpa penambahan antimikroba. Kandunganvitamin C pada paprika dengan perlakuan 0,4% minyak sereh pada suhu 8°C pada hari penyimpanan ke-27 masih tetap tinggi yaitu 1,5 mg/100g

Effect of Heat Moisture Treatment of Sago Starch on Its Noodle Quality

Sago starch has potential as source of flour for noodle. However, noodle made of sago starch has only been limitedly utilized due to the absence of gluten and lack of desired functional properties. Heat moisture treatment (HMT) is a promising technique for improving quality of sago noodle. The objectives of the present work were to study the effect of HMT of sago starch on its noodle quality. Four different origins of sago starch, i.e. Tuni, Ihur, Molat, and Pancasan, were treated with HMT method. HMT was performed by exposing the starch to high temperature (110oC for 16 hours) at moisture content of 25%. Sago starch was then processed into noodle. It was prepared by mixing the sago starch with binder (completely gelatinized starch and additive) into dough. The dough was pressed manually through a container with holes in the base. Noodles strains were steamed for 2 minutes and dried at 50oC in a convection drier. As the control, non-HMT sago starch was used and evaluated. Parameters evaluated were starch properties, physical strength, and cooking and sensory quality of the noodles. Analyses of variance was subjected to all parameters. Research results showed that the starch exposed to HMT changed its pasting profile from initial type A before treated to type B after treated. The noodle quality was also improved. Noodles resulted from starch treated with HMT showed higher firmness and elasticity, but they have lower stickiness compared to those of non-HMT. Less cooking loss and rehydration weight were also found, however, HMT increased cooking time of the noodles. HMT on Pancasan sago starch resulted in noodles which were preferred most by panelists. However, consumer testing is recommended to further validate consumers' preferences to the sago starch noodles. The study indicated that sago starch could be potentially used as raw material for noodles to increase the consumption of sago-based food

Survey Instrument Development for Consumer Perception Testing to RTE Product in Convenience Store

Global trade and the abolition of trade barriers lead to the proliferation of imported food products such as various types of fast food products (RTE: ready-to-eat food) sold by convenience stores mainly scattered in Jakarta. The question is what causes consumers choose certain convenience store to buy RTE Product and not choose another outlet category. To understand consumer perceptions, it is necessary to develop an instrument for measuring consumer perceptions of the option to purchase RTE Product at convenience stores. Variables used in this research are the perception and knowledge of the public/consumers against food safety, store attributes, service, and product attributes. The instrument used in this study is a questionnaire with a scalemeasuring1-5 to see the relationship between variables, we used the method of Structural Equation Modeling (SEM). The sample used in this study was 223 respondents that were divided into five areas in Jakarta, namely Central Jakarta, West Jakarta, South Jakarta, East Jakarta, and North Jakarta. The final outcome of the instrument development process was 25 observed variables, consisting of 4 indicators, which valid and reliable, with T-values for each observed variable is above 2,58, and Construct Reliability values range between 0,76 to 0,853

Karakteristik dan Studi Kasus Penerimaan Mi Sagu oleh Masyarakat di Sulawesi Selatan (Characteristics And Case Study Of Sago Noodle\u27s Acceptability By Consumer In South Sulawesi)

Noodle is the most popular product for the Indonesian people. It could be served conveniently without inferior image. Development of transparent noodle would promote consumption of saga Therefore, sago image as staple food would increase as superior as rice grain or wheat. The objectives of the research were to evaluate transparent noodle quality made from two types of sago starches and their acceptability by consumer (case: South Sulawesi). Noodle was prepared by mixing the thy sago starch with "binder" (completely gelatinized starch and additive) into dough. The dough was pressed manually through a container with holes in the base. Wet noodle was boiled in water and taken out of the water as soon as the strand floated, and were immediately transferred into cold water, and held before draining. Vegetable oil was added to avoid sticking. Sago (Metroxylon sago) starch were obtained from Pancasan Bogor and Palopo South Sulawesi, respectively. Noodle was then analyzed for quality and introduced to the consumers in South Sulawesi. They were represented by elementary school students (n=40), adults (n=40) and housewife (n=28). The result indicated that the physical characteristics of sago starch originated from Pancasan Bogor and Palopo were alike. However, they were different in term of starch pasting characteristics. Based on its raw material, Palopo starch showed the highest yield. Consumer\u27s acceptability study indicated that transparent sago noodle was well accepted by more than 70% of consumers. The product contributed approximately of 7% of the daily calory intake (based on 2000 kkal RDI for Indonesian)
