Abstract

Utilization of Moringa is still not well known, normally known as one of the veggie menu. In addition to direct consumption in fresh form, Moringa can also be processed into powder form that can be used as a base material for food products, such as processed cakes,biscuits and other processed. This study aims to determine the concentration of Moringa fruit juice that gives the best effect against chemical and organoleptic properties cake. The research was conducted from January to March 2018 in the Laboratory of Agro-Industry, Faculty of Agriculture, University,of Tadulako. Research using completely randomized design (CRD) and a randomized block design (RBD) the factors which consist of 5 level of concentration, ie 37,5%, 41,1%, 44,4%, 47,3% and 50% were repeated 3 times so that obtained 15 experimental units. Treatment significantly or very real then tested further using honestly significant difference test (HSD) level of 5% or 1%. The results showed that the chemical and organoleptic characteristics of the best there is on the cake with a concentration of moringa juice 50%, with a content of 29.84% moisture, 7.79% protein content, fat content of 23.52%, 0.60% fiber content.

Abstract

Penelitian ini bertujuan untuk mengetahui karakteristik kimia dan organoleptik daging buah  srikaya pada berbagai suhu pemanasan pulp dan untuk mendapatkan suhu pemanasan tertentu yang memberikan karakteristik kimia dan organoleptik terbaik pada pulp srikaya. Penelitian ini dilaksanakan pada bulan September sampai dengan November 2013, bertempat di Laboratorium Teknologi Hasil Pertanian, Fakultas Pertanian, Universitas Tadulako Palu. Menggunakan rancangan acak lengkap untuk analisis kimia dengan 4 taraf perlakuan  suhu pemanasan yaitu, tanpa pemanasan, 50oC, 60oC dan 70oC. Sedangkan untuk uji organoleptik menggunakan rancangan acak kelompok di mana pengelompokkan didasarkan pada masing-masing panelis, jumlah panelis yang dilibatkan sebanyak 15 orang.  Hasil penelitian menunjukkan bahwa peningkatan suhu pemanasan hingga 70oC menyebabkan penurunan terhadap mutu kimia antara lain kadar air, kadar serat dan vitamin C namun cenderung meningkatkan kadar gula reduksi. Selanjutnya pada mutu organoleptik, suhu pemanasan hanya berpengaruh terhadap uji warna. Suhu pemanasan 50oC memberikan pengaruh terbaik terhadap karakteristik kimia dan organoleptik buah srikaya.

Abstract

The study aims to find out a better concentration of dragon fruit peel extracted which capable to produce soybean and coconut milk products with stable color,  conducted in completely randomized design on two factors for chemical analysis, the first factor consisted of 3 levels dragon fruit peel extracted concentration of 20%, 30%, 40%, and the second were the product of soybean and coconut milk. The organoleptic test using a randomized block design in which the grouping was based on each panelist, the number of panelists with 15 people. Analysis parameters including color, aroma, taste, overall favorite. The results of  study showed that the better concentration of dragon fruit peel extracted was 40% that be able to produce high quality soy milk with natural color stable chemical characteristics included free fatty acid content of 0.01% and 1,15x107 cfu/ml of total microbial. Furthermore, the quality organoleptic, dragon fruit peel extract concentration of 20% were the best result that included aroma, taste and overall favorite scores were 5 (quite like), 4  (neutral) and 4 (neutral). The best concentration of dragon fruit peel extracted on soy milk the that concentration of 40% particularly  for free fatty acid  (0.69%) and total microbial (1,36x107 cfu/ml).  Futhermore, on organoleptic quality showed that the 20% concentration were the best score for aroma, flavour and overall favorite namely 5 (quite like), 4 (neutral) and 5 (quite like) respectively.

Abstract

The objectives of this study was to determined the concentration of gelatin that of the best in the production of jelly candy from sugar apple juice were physical, chemical and organoleptic characteristics. This study used completely randomized design with using sugar apple juice concentration as treatment consists of 4 degree i.e.6, 8, 10 and 12% (w/w). The organoleptic test using a randomized block design classification was based on each panelist, then the number of them panelist were involved 15 people. each treatment was repeated two times, so that would be obtained 8 samples. The treatment is significant in a further test with honestly significant difference test level of 5%.The results showed that the physical quality of the gelatine concentrations differences to have total soluble solid. The highest content of it made from gelatine 8% that is 1,94%, the solubility 12% (7.70%) and the water holding capacity at the 6% (2.82%), oil holding capacity at the 6% (2.15%), chemical quality such as water content at the8% (62.46%), vitamin C 6% (33.00% ) and dietary fiber at the 12%(7.46%). While the best of organoleptic test concentrations of gelatine at the 8% i.e the texture 4.20, colours 5.40, flavour 4.27, taste 4.27 and alike of comprehenship 4.80 which the were included neutral.

Abstract

Penelitian ini bertujuan untuk mengetahui kondisi optimum sintesis Carboxymethyl Cellulose (CMC) melalui kombinasi perlakuan Kalium Hidroksida (KOH) Natrium Monokhlor Asetat (NaMCA) dan suhu yang optimal serta identifikasi karateristiknya melalui rendemen, viskositas, Derajat Subsitusi (DS), Water Holding Capacity (WHC), dan Oil Holding Capacity (OHC). Penelitian ini menggunakan Response Surface Methodology (RSM) dengan 3 faktor dan 5 level masing ? masing NaMCA (3,18-6,68g) dalam 20 ml KOH (11,59-28,41%), 100 ml isopropanol pada suhu (46,59-63,41oC). Parameter pengamatan meliputi rendemen, viskositas, derajat subsitusi (DS), Water Holding Capacity (WHC), dan Oil Holding Capacity (OHC). Hasil penelitian menunjukkan bahwa kondisi optimum sintesis CMC terhadap karateristiknnya diperoleh pada kombinasi perlakuan pada konsentrasi KOH 20% (w/v), NaMCA 5 gram dan suhu pada 47,60oC, dengan diperoleh nilai rendemennya sebesar 7,5226 gram, DS sebesar 0,82, WHC sebesar 6,51 g/g, OHC 3,59 g/g, dan nilai viskositasnya 0,095 cp.
