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

The Belanda eggplant  is  one  of  multipurpose  fruit  commodity,  classified  as  a commercial commodity and has a cheap price, especially in the harvest season. The Belanda eggplant including climateric fruit have sour taste, contains many useful nutrients for health, the nutrient content of which is vitamin C, antioxidants, vitamin E, and many others. The addition of pectin and sorbitol can improve  the quality  of  physical, chemical, and organoleptic slice jam. The  research  method used Completely  Randomized Design(CRD) factorial pattern with two factors  and  three  replications.The  first  factor:  the  addition  ofpectin(0.25%, 0.50%, 0.75%, 1.00%), and  the  second  factor:  the  addition  of  sorbitol(5%, 10%, 15%, 20%). The  results showed  the  addition  of  pectin  treatment  of  0.25% and  the  addition  of  sorbitol15% yield  of acceptable slice jam consumers. The  treatment resulted  in water levels 21.169%, 28.444% antioxidant  activity,  gel  density  3.273  mm/gr.sec,  60.433% yield,  flavor  (neutral) 4.50  and texture (like) 6.67 .Key words : slice jam, Belanda eggplant, pectin, sorbitol

Abstract

ABSTRAKPenggunaan jagung saat ini masih perlu ditingkatkan dalam rangka peningkatangizi masyarakat. Salah satu usaha meningkatkan konsumsi protein jagung adalahdengan mengkombinasikan jagung dengan kacang koro pedang putih , sehinggadiharapkan dapat saling melengkapi dalam kontribusi kandungan asam amino yanglebih lengkap pada produk yang dihasilkan. Salah satu produk kombinasi jagung dankacang koro pedang putih adalah yoghurt. Tujuan penelitian ini adalah mempelajaripengaruh proporsi jagung dan kacang koro pedang putih dengan penambahan sususkim terhadap kualitas yoghurt yang dihasilkan. Penelitian ini menggunakanRancangan Acak Lengkap Pola Faktorial (2 faktor) dan 3 kali ulangan. Faktor pertamaadalah proporsi jagung dan kacang koro pedang putih ( 70:30, 60:40, 50:50) Faktorkedua adalah Konsentrasi susu skim ( 5%, 7%, 9%). Perlakuan terbaik adalahkombinasi proporsi jagung dan kacang koro pedang putih 60:40 dengan konsentrasisusu skim 9% . Produk yoghurt tersebut mempunyai kadar protein 4.31%, pH 4.0,lemak 0.99%, Total BAL 10.966 (cfu/g), total asam 0. 61%, Viskositas 2.175 cps,dengan total ranking uji kesukaan aroma = 138.5, warna = 137.5 dan skor tekstur =115Kata kunci: Yoghurt, Jagung, Kacang Koro Pedang Putih, Susu SkimABSTRACTThe use of corn (Zea mays) is currently needs to be improved in order toimprove public nutrition. One effort to increase the protein consumption of corn is thecorn combine with white legume (Canavalia ensiformis), which is expected tocomplement the contribution of amino acid content in the resulting product. One of theproducts the combination of corn and white legume is yogurt. The purpose of this studywas to know the influence of the proportion of corn and white legume with the additionof skim milk on the quality of yoghurt produced. This research used Factorial CompleteRandomized Design Patterns (2 factors) and 3 repetitions. The first factor is theproportion of corn and white legume (70:30, 60:40, 50:50). The second factor is theconcentration of skim milk (5%, 7%, 9%). The best treatment is a combination of theproportion of corn and white legume 60:40 with a concentration of 9% skim milk. Theyoghurt products have protein content 4:31%, pH 4.0, fat 0.99%, Total BAL 10 966(cfu/g), total acid 0. 61%, viscosity of 2,175 cps, with a total ranking of test A = 138.5aroma, color = 137.5 and scores texture = 115Keywords: Yoghurt, Corn, White Legume, Skim Milk

Abstract

ABSTRAKMengingat semakin pentingnya arti kesehatan bagi masyarakat terutama dipedesaan, maka perlu ada langkah-langkah inovatif dalam mengembangkan sumberdaya lokal seperti buah mangrove jenis pedada. Kelompok tani mangrove “ KAMPUNGMINA MANGROVE” telah memanfaatkan buah pedada untuk sirup dan sisa hasilpengolahan berupa ampas diproses menjadi tepung dan diaplikasikan untuk produkmakanan. Namun produk tepung dari ampas tersebut tidak memiliki nilai fungsionalkarena salah proses pembuatannya. Sehingga melalui program PTbM ini akandilakukan proses pengolahan tepung pedada yang memiliki nilai fungsional. Metodeuntuk memfasilitasi peningkatan ketrampilan kelompok tani mangrove tersebut yaitumemberikan sosialisasi, pelatihan pengolahan tepung dan metode pendampingan.Pelatihan ini lebih mengedepankan partisipasi aktif kelompok tani mangrove sertamemberikan pendampingan untuk keberlanjutan kegiatan produksi tepung pedada.Hasil pelatihan menunjukkan bahwa kelompok tani mangrove terampil dalammenggunakan alat pengering kabinet yang awalnya dilakukan secara manual.Bertambahnya wawasan para kelompok tani mangrove tentang manfaat tepung buahpedada terhadap kesehatan, dan aplikasinya pada produk pangan. Metodependampingan dapat memberikan dampak dalam memproduksi tepung buah pedada.Kata kunci : teknologi pengolahan, tepung pedada, petani mangrove, Wonorejo TimurABSTRACTGiven the growing importance of health for society, especially in rural areas, itis necessary innovative steps in developing local resources such as mangrove fruitspecies of pedada. Farmers group of mangrove call "KAMPUNG MINA MANGROVE"has utilized pedada fruit to produce syrup, the waste product from it was processedinto the flour and applied to food products. However, flour products from the wastedidn’t have functional value because there were many mistake in the process, so thePTbM program that is the solution of it. Methods of program used to facilitate theincreasing skills of the mangrove farmer groups i.e., provide socialization, trainingprocessing of the flour mangove and mentoring activities. The training emphasizes theactive participation of farmers group mangrove as well as provide assistance to thesustainability of production activities pedada flour. The results showed that the farmersgroup of mangrove being skilled in operating cabinet dryer that previously wasmanually, the increase of knowledge about function of pedada flour toward health, andits application pedada flour in food products. Mentoring methods can provide producingpedada flour.Keywords: processing technology, pedada flour , mangrove farmers, Wonorejo Timur village

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.
