Abstract

The purpose  of this study was to determine the effect of the white maize starch by oxidation and acetylation-oxidation modification on gel formation and character of the resulting gel, and applying a modified white corn starch in manufacturing of marshmallow cream. White corn varieties Srikandi, Pulut and Canggal are used as raw materials to produce starch. Starch modification is conducted by oxidation and acetylation-oxidation. Quality analysis of the modified starch is freeze thaw stability, smallest gel formation concentration and gel strength. Corn starch, both native and modified applied in manufacturing of marshmallow cream. The results showed that the treated starch acetylation-oxidation provide the best freeze thaw stability with the least water released than native starch and modified starch oxidation. Starch modified by oxidation tend to have the highest Least Gelling Concentration (LGC). Gel produced from modified starch both oxidation and acetylation-oxidation has a gel strength greater than the native starch. Marshmallow cream that uses a modified starch by acetylation-oxidation, have the best received power in testing organoleptic by the panelists. Use of modified starch does not give a noticeable difference in color of the product, but it gives texture and the best spread power compared to products using original starch.

Abstract

ABSTRACT This research was aimed to study the energy potential of quicklime stone chemoreaction for the application to drying process of red chilli seeds. The experiment demonstrated that chemoreaction energy released from wafer reaction with CaO containing lime stone could be used for drying process of chilli seeds at ambient temperature to a very low moisture, varying of 2.5 - 3.7 % wb. The chemoreaction energy released from reaction between lime stone and plane water was 1.06 kJ/g lime stone. At excessive water condition partcle sizes of lime stone did not affect chemoresctton energy. but smstter size psttictes enhanced tile energy release from the reaction. Using three particle sizes of lime stone the energy efficiency for drying of red chilli seeds ranged 54.0 - 64.0 % and for plane water evaporation ranged 57.4 – 71.6 %. The energy effectiveness for chilli seeds drying was 4.7 kJ/g water and for plane water evaporation was 4.1 kJ/g, implying the presence of bound water in the chilli seeds. Diterima: 1 Juni 2006; Disetujui: 21 Maret 2007

Abstract

The physicochemical and functional properties of starches (tapioca) from five varieties Manihot utilisima Crantz (Thailand, Kasetsar, Pucuk Biru, Faroka and Adira-4) from Lampung were evaluated. All tapioca samples showed a typical A-type diffraction pattern, indicating that variety had no effect on it. However, the starch crystallinity was affected. Some parameters of physicochemical and functional of tapioca from five varieties varied significantly (p < 0,05). Analysis of correlation showed that amylose, fat, ash as well as crystalinity and swelling power affected some of pasting and gel texture parameters. Digestion of gelatinized starch was also affected by root varieties. Keywords: physicochemical properties, pasting, texture, crystalinity

Penelitian ini bertujuan untuk mempelajaripengaruh berbagai faktor perlakuan dingin terhadap kristalisasi danfraksinasi minyak kelapa, serta untuk menetapkan prosedur pendinginanyang efektif dalam menghasilkan fraksi minyak dengan kandungan MCTtinggi. Penelitian dilaksanakan di Laboratorium SEAFAST CENTER IPBdari bulan Maret 2012 sampai bulan Februari 2013. Fraksinasi dilakukandengan memanaskan minyak pada suhu 70°C lalu didinginkan padaberbagai laju pendinginan untuk mencapai beberapa variasi suhukristalisasi, diaduk dengan kecepatan 15 rpm, dibiarkan mengkristal padalama waktu yang berbeda (hingga 900 menit), serta difraksinasi denganpenyaringan vakum menggunakan kertas Whatman 40. Tiga tahappendinginan yang merupakan faktor kunci keberhasilan proses kristalisasiminyak kelapa yaitu tahap pendinginan awal dari suhu 70 hingga 29°C;tahap pendinginan kritis 29°C hingga suhu kristalisasi; dan tahapkristalisasi itu sendiri. Pada tahap pertama minyak kelapa didinginkansecepat mungkin untuk menurunkan waktu proses, tetapi pada tahap keduaharus dilaksanakan dengan laju pendinginan lambat (kurang dari 0,176°C/menit) untuk menghasilkan kristal yang berukuran besar dan tidak mudahmeleleh. Minyak dengan kandungan triasilgliserol tinggi dapat diperolehdari fraksi olein minyak kelapa. Pada perlakuan suhu kristalisasi 21,30-21,73°C untuk laju pendinginan kritis antara 0,013 hingga 0,176°C/menit,semakin rendah laju pendinginan kritis dan semakin lama proseskristalisasi maka kandungan MCT fraksi olein yang dihasilkan akansemakin tinggi.Kata kunci: minyak kelapa, laju pendinginan, kristalisasi, fraksinasi, MCTABSTRACTCoconut oil is the main source of medium chain triglycerides(MCT). Fractionation produce oil fraction containing MCT concentrate.This research aims to study the influence of various factors of coolingtreatment on the crystallization and fractionation of coconut oil, and toestablish effective cooling procedure to produce oil fraction with highMCT content. The research was conducted in Laboratorium of SEAFASTCENTER IPB from March 2012 to February 2013. Coconut oil washeated at 70°C then cooled at different cooling rate to reach variouscrystalization temperatures. The oil was then stirred at 15 rpm and allow tocrystallized at different period of time (up to 900 min), and finallyfractionated by vacuum filtration using Whatman #40 paper. Fractionationtemperatures was the same as crystalization temperature. The resultsshowed that there were three distinct cooling regimes critical tocrystallization process, i.e temperature range from 70 to 29°C; 29°C tocrystallization temperature; and crystallization temperature. In the firstregime, melted coconut oil might be cooled quickly to save time, but in thesecond regime need be done with a cooling rate of less than 0.176°C/minto produce physically stable crystal. Oil with high triacylglycerol contentcould be obtained from olein fraction of coconut oil. At the crystallizationtemperature 21.30-21.73°C for the critical cooling rate between 0.013 to0.176°C/min, the higher MCT content of olein fraction were produced bythe lower critical cooling rate and the longer crystallization process.Keywords: fractionation, crystallization, MCT, coconut oil, cooling rate.

Abstract

Lipase-catalyzed interesterification is used to synthesize a value added structured lipid (SL) from coconut oil and palm oil. SL is a modified lipid (triacylglycerols; TAG) with replacement and/or arrangement of fatty acid positions to change the fatty acid composition and/or their positional distribution in glycerol backbone. In this research, modification was conducted by enzymatic process, to produced SLs with some beneficial changes in chemical and physical properties.  Sepecifically, objective of this research was to study the oxidative stability of SL obtained from enzymatic interesterification of coconut oil and palm oil. Stability was studied using schaal oven test method and parameters tested were free fatty acid, peroxide value, anisidine value, total oxidation, and thio barbituric acid (TBA) value. Results showed that the type of lipase used and length of interesterification resulted in SL with different oxidative stability. Among SLs evaluated, SL produced with esterification process using lipase of Novozyme 435 for 5 hours has high oxidative stability. At the end of the observation, product that was stored for 4 weeks at 50 oC, contained free fatty acid value of 4.21 %, peroxide value of 2.88 meq O2⁄kg, anisidine value of 5.16, TBA value of 2.01 mg malonaldehyde/kg sample, and total oxidation of 10.92. Those result shows that oxidation stability parameter of structured lipid still meet the standard of palm oil  product and its derivatives AbstrakInteresterifikasi enzimatik dengan lipase digunakan untuk mensintesis lipida terstruktur (structured lipid/SL) dari bahan baku minyak kelapa dan kelapa sawit.

Abstract

The study aimed to evaluate free glutamate content occurs naturally in prepared foods or dish menus. Fifteen selected Indonesian dish menus were categorized to three major groups, i.e. dish menu with monosodium glutamate (MSG) addition, dish menu with seasoning and/or condiment containing glutamate addition, and dish menu with MSG, seasoning and/or condiment containing glutamate addition. Each dish menu was prepared at the kitchen laboratory by standardizing the ingredients, composition and cooking process, followed by analysis of free glutamate content in dish menu, its raw material mix, and basic seasoning using HPLC method. The study results showed that raw materials such as chicken, fermented-tofu solid waste (oncom), meatball, cabbage, fried onion, tomato, and fried potato contributed to the free glutamate content in dish menus. Addition of MSG, seasoning and/or condiments de nitely contributed to free glutamate content in the dish menus, ranged 9.8-142.9% for MSG added and 7.9- 100% for seasoning and/or condiments added. The dish menus with MSG addition which contributed to higher free glutamate content were fried tempe, rice cake with vegetable soup in coconut milk, and spiced chicken soup. Meanwhile, the dish menus with seasoning/ condiment addition contributed to higher free glutamate content were stir-fry water crest, mixed vegetable in chicken soup, chicken rice porridge. Cooking practices could increase or reduce free glutamate content in dish menus, ranged from -86.2 to 43.3%.

Abstract

Red palm oil (RPO) contains high carotene which can be used as coloring agent and source of provitamin A. Drying technology by means of spray dryer is used in order to concomitantly reduce moisture content of RPO microencapsulates and maintain its carotene content. The objective of this research was to study the scale-up process of the RPO microencapsulate production from laboratory scale (8.3 mL/min) to pilot plant scale (300 mL/min). At laboratory scale, using Buchi 190 spray dryer, the optimum formulation of (Maltodextrin:Gum Arabic) : RPO was (35:15) : 40 or 0.8 parts of RPO compared to one part of microencapsulate coating. At pilot-scale (i.e., 300 mL/minute), the optimum formulation from lab-scale could not be considered as the optimum one based on carotene content as main parameter. At constant parameter inlet temperature of 215oC, outlet temperature of 110oC, pump pressure of 4.5 bar, cyclon speed of 2500 m3/hour, and flow rate of 300 mL/minute, the best microencapsulates could be produced at ratios of coating agent and RPO ranging from 1:0.3-1:0.6. At pilot scale, flow rate and droplet size were the most important factors in order to produce the dry microencapsulates.

Abstract

In Indonesia, commercially sterilized flavored liquid milk is regulated requiring minimum F0-value of 3.0 minutes. Due to batch thermal processing operation, a waiting time, period for product holding before sterilization process at room temperature, is necessary. Waiting time is identified as a critical factor due to potential increase in initial microbial load. Consequently, increase of waiting time might be associated with the need of higher F0-value. The objective of this study was to evaluate the effect of waiting time (0, 1, 2, 3, 4, 5, and 6 hours) and process temperatures (121.9, 122.6, and 123.9˚C) for fixed processing time (10 minutes) on the selected quality parameters of commercially sterilized flavored liquid milk. Our result showed no significant increase on the number of microbes, pH, and viscosity of the milk after waiting time up to 6 hours. After sterilization, all products tested with waiting time up to 6 hours and processing temperature at 121.9˚C (F0–value of 11.00-13.54 minutes), 122.6˚C (F0–value of 15.49-17.01 minutes), 123.9˚C (F0–value of 20.53-21.46 minutes) were organoleptically acceptable. However, decrease of vitamin B1 (6-7, 9.6-10.4, 22-23%), vitamin C (45-50, 100, and 100%) were observed at processing temperature of 121.9, 122.6, and 123.9˚C, respectively. These findings shows that the use of processing temperature of 121.9˚C (F0-value of 11.00-13.54 minutes) is consider to be the best alternative to produce commercially sterilized flavored liquid milk having waiting time up to 6 hours.
