Abstract

Pulsed  electric  field  processing  represents  a  promising  non-thermal  technology which involves the application of pulses of high voltage (20-80 kV/cm) for less than one second  to  fluid  foods  placed  between  two  electrodes.  During  the  application  of  certain PEF conditions microbial inactivation occurs by causing a pore formation and destruction of  the  cell  membranes The  purposes  of  the  present  study  were  (i)  to  inactivated  of Staphylococcus  aureudecreas  using  pulsed  electric  field  and  (ii)  physicochemical properties of raw milk. Intensity field strength that used are  30 and 60 kV/cm, with pulses number  10,  20, and 30. The  results  showed  that  higher  decrease  of  population  of Staphylococcus  aureus  with intensity 60  kV/cm and pulses  number  30 (0,6  log cycle) and PEF methods give unsignificant effect on pH and total acid.Key words : pulsed electric field, population,  Staphylococcus aureus

Abstract

Wild yams (Dioscorea spp.) grow well in Indonesia known as Uwi, is the kind of tubers that grow in the community,but they have not been used optimally. Publicity about the characteristics and types has been limited. The tubers contain inulin, but also there have been no publication related.The purpose of this study was to uncover the characteristics of wild yam and inulin profiles contained in the tubers.The yams were obtained from various regions in East Java, among others Pacet Mojokerto, Karang Ploso and Kawi Mountains in Malang, Nganjuk, and traditional markets in Surabaya.The tubers were characterized for shape and size of tubers, skin color and flesh tubers, average weight and texture of the tuber, moisture content, ash content and levels of inulin, texture and flavor. The data were analyzed using Analysis of Variance (ANOVA) and further test Duncan’t Multiple Range Test (DMRT).Based on the characteristics of tubers, there were 10 types of wild yams, namely D1 (Dioscororea alata/ white yam), D2 (Dioscorea pinthaphylla/frog yam), D3 (Dioscorea hispida /Gadung), D4 (Dioscorea alata /purple yam with yellow skin), D5 (Dioscorea alata /purple yam), D6 (Dioscorea esculenta/gembili), D7 (Dioscorea alata/yellow yam), D8 (Dioscorea opposita/white yam with yellow skin), D9 (Dioscorea bulbifera/gembolo) and D10 (Dioscorea rotundata/ white yam with brown skin). The highest levels of inulin obtained in Dioscororea esculenta (gembili) ie 14.77 % (db). The water content rangedbetween 71.89- 85.07 % (wb), ash content 0.59- 1.83 % and texture between 0.012 to 0.055 (mm/g.dt). Organoleptic score was 2.75 to 4.55 texture and taste is from 3.20 to 5.00.ABSTRAKUwi merupakan jenis umbi-umbian yang tumbuh di Indonesia, namun belum dimanfaatkan secara optimal dan belumbanyak publikasi mengenai kharakteristik dan jenis-jenisnya. Uwi mengandung inulin, namun belum banyak publikasi yang mengungkap kadar inulin pada berbagai jenis umbi uwi tersebut.Tujuan dari penelitian ini adalah mengetahui kharakteristik fisik dan kimia jenis-jenis umbi uwi (Dioscorea spp.), serta profil inulin yang terkandung dalam masing-masing umbi.Beberapa jenis uwi diperoleh dari berbagai daerah di Jawa Timur, antara lain Pacet Mojokerto, Karang Ploso dan Pegunungan Kawi Malang, Nganjuk, dan pasar tradisional Surabaya. Karakteristik fisik yang diamati meliputi , bentuk dan ukuran umbi, warna kulit dan daging umbi, berat rata-rata dan tekstur umbi. Karakteristik kimia yang diamati meliputi kadar air, kadar abu dan kadar inulin. Karakteristik organoleptik pada uwi kukus yang diamati adalah tekstur dan rasa. Data yang diperoleh dianalisis menggunakan Analisis Varian (ANOVA) dan uji lanjut Duncan’t Multiple Range Test (DMRT).Dari hasil karakterisasi diperoleh 10 jenis uwi yaitu D1 (Dioscororea alata/uwi putih), D2 (Dioscorea pinthaphylla/ uwi katak), D3 (Dioscorea hispida/uwi gadung), D4 (Dioscorea alata/uwi kuning kulit ungu), D5 (Dioscorea alata/ uwi ungu), D6 (Dioscorea esculenta/gembili), D7 (Dioscorea alata/uwi kuning), D8 (Dioscorea opposita/uwi putih kulit kuning), D9 (Dioscorea bulbifera/gembolo), dan D10 (Dioscororea rotundata/uwi putih kulit coklat).Kadar inulin tertinggi diperoleh pada Dioscororea esculenta (gembili) yaitu 14,77 % (db). Kadar air berkisar antara71,89-85,07 % (wb), kadar abu 0,59-1,83 % dan tekstur   antara 0,012-0,055 (mm/g.dt). Skor organoleptik tekstur adalah 2,75-4,55 dan rasa adalah 3,20-5,00.

Abstract

Pedada fruit contains 56.74 mg/100 g of vitamin C and 79% of water.  One of the uses of this fruit is for a raw material of fruit ice cream. Objectives of this research was to evaluate quality of fruit ice cream made from padada fruit and young coconut juice with addition of Carboxy Methyl Celulose (CMC). Randomized completely design with two factors was implemented in this research. The first factor was proportions of pedada fruit and young coconut juice consisting of three levels, that was i.e., 25%:75%, 50%:50%, and 75%:25%.  The second factor was CMC concentrations consisting of three levels, that was i.e., 0.1, 0.2, and 0.3%.  The best quality of fruit ice cream was obtained from 25% padada fruit juice and 75% young coconut juice with addition of 0.3% CMC.  The physical and chemical characteristics of the ice cream were a melting time of 11.11minute/10g, an overrun of 5.71%, a relative viscosity of 8.15 (Poiseuille x103), a fat content of 0.06%, a protein content of 1.29%, and a vitamin C content of 0.76mg/10g. The sensory characteristics of the ice cream were brownish, rather sour and sweet, and pedada-fruit aroma.
