Abstract

Pentingnya ketahanan pangan telah lama disadari oleh pemerintah. Namun demikian, kondisi ketahanan pangan masih sangat memprihatinkan, terutama ditunjukkan oleh tingginya jumlah individu yang masih mengalami malnutrisi. Hal ini antara lain disebabkan oleh kurangnya upaya pemberdayaan industri pangan penghasil nilai tambah berbasis potensi lokal. Karena itu, menjadi sangat penting untuk mengembangkan konsep dan program kemandirian pangan: dimana (i)kontribusi sumber daya lokal/indigenous; (ii) tingkat keanekaragaman sumber pangan; dan (iii) tingkat ketergantungan impor pangan dan ingridien pangan, merupakan indikator yang sama pentingnya dengan indikator ketahanan pangan; yaitu kesehatan dan keaktifan individu. Teknologi pangan mempunyai peranan penting dalam pengembangan penganekaragaman pangan; khususnya di tingkat industri. Industrialisasi pangan lokal harus dilakukan dengan mengkreasikan nilai tambah sedemikian rupa sehingga produk yang dihasilkan mempunyai nilai lebih-atau paling tidak sama- dengan produk pangan berbasis beras (atau gandum) yang saat ini masih mendominasi menu pangan Indonesia. Penelitian dalam bidang ilmu dan teknologi pangan untuk mengeksplorasi karakteristik dan fungsionalitas unik pangan lokal; untuk mengindentifikasi dan memetakan preferensi dan kebiasaan konsumen lokal perlu dilakukan secara intensif.The importance of food security has long been well realized by the government. However, condition of food insecurity; as reflected by the high number of mal-nutritious individuals in Indonesia; is still alarming. This is due to the lack of effort in empowering the potent of local-based food industry that can produce added value. Therefore, it is highly important to develop the concept and program in food independency. Within this concept and program, (i) contribution of local/indigenous resources, (ii) level of diversity of food/dietary sources, and (iii) level of food ingredients and imported food dependency are as important as the indicators of food security, such as individual health and activity. Food technology has to play its role in developing food diversification; especially at industrial level. Industrialization of local-based foods should be conducted by creating added values in such a way that the local food products have a better value than or at least the same as that of rice (and wheat) based food products which are currently dominating traditional Indonesian menu. Research on the food Science and technology in order to explore the unique characteristics and functionalities of local foods, to identify and to map local preferences and consumers habits should be conducted intensively.

Abstract

Krisis pangan dan gizi merupakan permasalahan yang berdampak terhadap pembangunan di Indonesia. Tujuan penelitian ini adalah untuk mengembangkan protokol pencegahan dan penanggulangan krisis pangan dan gizi. Data yang digunakan terdiri dari data sekunder dan primer. Protokol krisis pangan dan gizi dikembangkan dengan melibatkan ahli dan narasumber dari pemerintah daerah di Sukabumi, Situbondo dan Bogor. Kondisi krisis pangan dan gizi dapat ditetapkan dengan sistem survailan menggunakan indikator yang valid, sensitif, dan mudah dikumpulkan. Model yang sudah ada yaitu “Sistem Kewaspadaan Pangan dan Gizi” dapat digunakan dengan beberapa modifikasi tertutama pada komponen indikator. Protokol pencegahan dan penanggulangan dikembangkan untuk kelompok rumah tangga rawan di masyarakat. Kelompok ini dapat ditetapkan berdasarkan 14 indikator nonmoneter yang dikembangkan oleh BPS, dengan prioritas yang mempunyai anak di bawah usia lima tahun dan atau ibu hamil. Upaya penyelamatan terutama dilakukan dengan memberikan makanan tambahan pada kelompok rawan ini. Penanggulangan diarahkan melalui bantuan ekonomi kepada rumah tangga sasaran. Pemerintah daerahperlu membentuk tim manajemen krisis pangan dan gizi yang disertai peran dan tanggungjawab yang jelas. Disarankan, pemerintah daerah mempunyai kewenangan dalam menetapkan kondisi krisis, yang disertai anggaran pelaksanaan protokol tersebut. Selain itu, dalam jangka panjang program seperti SKPG, Posyandu dan UPGK perlu diperbaiki dan ditingkatkan.Food and nutrition crises affect Indonesian development. This study aims to develop general protocol for prevention and recovery of food and nutrition crises. The data comprises of secondary and primary data. The crisis protocol is developed by involving experts and resource persons from Sukabumi, Situbondo and Bogor local governments. The crisis condition could be determined using mechanism of surveillances, valid, sensitive, and easy to generate indicators. The existing “Sistem Kewaspadaan Pangan dan Gizi” model could be applied with some modification on its components. The recovery and prevention protocolshould specifically be developed for vulnerable groups which can be determined using 14 non-monetary indicators developed by CBS, with special priority given to households with children under 5 years and/or pregnant mothers. The recovery is focused on feeding program for those groups. Prevention program is designed for the development of economic activities for the targeted households. The local government need to establish a crisis management team with well defined roles and responsibilities. It is proposed that Head of Local Governments should have authority to determine, declare crisis condition, and allocate budget to execute the protocol. In the long run, existing food and nutrition programs; especially SKPG, Posyandu and UPGKshall be up-graded and improved.

Abstract

Berkembangnya teknologi proses pengolahan pangan berdampak pada kebutuhan lipida dengan sifat khusus untuk diaplikasikan pada produk tertentu. Sifat lipida alami belum tentu sesuai dengan kebutuhan industri, baik dari segi sifat fisikokimia, gizi, maupun sifat fungsional lain yang diinginkan.  Karena itu, perlu dilakukan modifikasi untuk membentuk lipida dengan nilai tambah tertentu. Salah satunya melalui modifikasi stuktur molekuler lipida; yaitu untuk menghasilkan lipida terstruktur (structured lipids, SL). Lipida terstrukturadalah lipida yang termodifikasi, dengan penambahan dan/atau pengaturan posisi asam-asam lemak pada kerangka gliserolnya untuk tujuan menghasilkan lipida dengan nilai tambah sesuai aplikasinya.  Perbedaan jenis dan posisi asam-asam lemak pada kerangka gliserol akan menentukan sifat kimia, fisika, biokimia lipida dan fungsionalnya yang berpotensi memberikan nilai tambah tertentu. Sintesis SL dengan interesterifikasi secara kimia maupun enzimatis memungkinkan potensi aplikasi yang lebih luas, khususnya untuk industri pangan fungsional. Saat ini telah beredar di pasaran produk SL dengan nilai tambah tertentu; misalnya mudah diserap tubuh, kandungan kalori lebih rendah, dan mempunyai komposisi asam lemak mirip dengan lemak ASI untuk formulasi makanan bayi.  Minyak kelapa dan kelapa sawit sebagai hasil perkebunan, yang masing-masing memiliki keunggulan kaya asam lemak rantai menengah dan kaya asam lemak tak-jenuh merupakan bahan bakupotensial untuk pengembangan SL dengan nilai tambah khas.Pembuatan SL sesuai dengan kebutuhan industri pangan fungsional ini dapat meningkatkan daya saing produk perkebunan dalam pasar dunia. Hilirisasi riset perlu dikembangkan agarmampu menghasilkan inovasiyang dapat diaplikasikan di industri, yang melibatkan komitmen pemerintah maupun pelaku usaha.  ABSTRACTThe growth of process technology in food processing affecting the needs of lipid with special characteristics for specific products. The characteristic of natural lipid is not always suitable with industry requirement, either from its physicochemical characteristic, nutrition, or from other desirable functional characteristics. Therefore it is necessary to develop modification technique to produce lipid with desirable added value, such as generating structured lipids (SL). Structured lipids is modified lipid, with the addition and/or arrangement of the fatty acid position on its glycerol backbone.The difference of types and positions of fatty acids on glycerol backbone will determine the chemical, physical, biochemical characteristic and the functionality of the lipid. Structured lipids synthesed by chemical or enzymatic interesterification will potentially have broader potential of applications, especially for functional food industry. Currently, SL products with several added values, such as more easily absorbed, lower calorie content, or having fatty acid composition similar to that of breastmilk lipid for baby food formulation, have been introduced in the market. Coconut oil and palm oil are, respectively, known to be rich in medium saturated fatty acid and unsaturated fatty acids. Both oil are potential to be used for development of SL. Structured lipids production suitable for functional food industry could increase the competitiveness of coconut and palm oil as plantation comodities in world market. Downstream policy research by promoting research and development toward industrial application is needed, involving commitment from government and private sectors.

Abstract

Modification of corn starch will give different effects depending on the corn variety. Gel forming capacity increased with increase in concentration of the samples and least gel concentration was maximal in higher amylose starch. Initial pasting temperature of native starch reduced from following oxidation and acetylation. Among the samples, the highest pasting temperature was recorded in native and values for peak viscosity during heating. The modified starch has better stability than native starch and lower tendency for syneresis and improve the freeze thaw stability.Keywords: white corn starch, oxidation, acetylation-oxidation, corn variety

Abstract

Dry fractionation will produce a fraction of olein and stearin with different composition of high melting and low melting as well the distribution of triacylglycerol (TAG) in the form of trisaturated (St3), disaturated (St2U) and monosaturated (StU2). This research aimed to study the effect of critical cooling rate and crystallization temperature on the composition and profile of TAG changes as well the melting properties of the fractionated coconut oil products. Coconut oilwas heated at 70°C then cooledat differentcooling rate to reach various crystalization temperatures. The oil was then stirred at 15rpm and allowed to crystallize at different period of time, and finally fractionated by vacuum filtration using Whatman #40 paper. Fractionation temperatures were the same as crystalization temperatures. The results showed that the critical cooling rate was proportional to the solid-like to liquid-like ratio, the content of St3 and SFC profile of olein fraction but inversely proportional to the content of St2U and StU2 TAG. Interval crystallization temperature between 21.30 and 21.73 °C produced the S/L ratio, the content of St3 TAG and SFC profiles of olein fractions lower and the content of St2U and StU2 TAG higher than the temperature interval below or above it. Coconut oil fractionation more effective in higher crystallization temperature or lower critical cooling rate. In these cooling treatments, St3 TAG which has high melting pointwould be concentrated at stearin fraction, while St2U and StU2 TAG and MCTwould be at olein fraction. Therefore, it will increase melting properties of stearin fraction and decrease olein fraction.

Abstract

The uses of white corn in Indonesia’s food industries are still limited. To explore the potential uses, evaluation of functional properties of white corn flour is needed. The objective of this study was to evaluate the gelatinization properties of white corn flour, and its changes as affected by spontaneous fermentation of white corn grits and particle size of its flour.  White corn flour was prepared by soaking of white corn grits followed by drying and grinding.  Soaking was done in a closed pan at a controlled temperature, to promote spontaneous fermentation.  The fermented  flour was fractionated by particle size using multiple sieves of 100 mesh (150 µm), 150 mesh (106 µm) and 200 mesh (75µm) and analyzed for its chemicals, physicals and gelatinization characteristics. The result showed that the smaller particle size resulted in increased breakdown viscosity and the tendency to retrogradate. Overall, the  result showed that control of length of fermentation of corn grits and particle size could be used as a mean to control breakdown viscosity and tendency to the retrogradation of the corn flour.

Abstract

Basic  information on physical and chemical properties of Gayam (Inocarpus edulis Forst), one of the domestic commodities, is still very limited. The objectives of this research were to investigate chemical composition of gayam seed and the functional properties of gayam starch, especially the pasting behavior and the characteristic of its gel. Moisture, crude protein, lipid, ash, and carbohydrate content of gayam seed, respectively, were 50.11% (w/w), 11.66%, 8.21 %, 3.39% , and 76.74% (dw). The gayam starch granules were very strong and remain physically intact  during  heating up to 90°C. The highest swelling-power (24.76) occurred at 95°C, with low amylose leaching (0.27% dw) and solubility (0.25° Brix). Pasting behavior of starch suspension (10% w/v) showed the initial pasting temperature at 81°C and  peak viscosity 750 Brabender unit (BU) reached at 90 °C. The paste viscosity was relatively  stable at 95°C. The gel was formed during  cooling. The gel of gayam  starch was unstable at (-16°C) at which six times freezing-thawing cycles resulted in 66.95% water dripped. The gel characteristics may indicated the high amylose content. Scanning electron micrographs of freeze-dried gel revealed the sponge-strucuture. The data indicated  that gayam starch has great potential to be explored further  for industrial applications.

Abstract

The 3-monochloropropane-1,2-diol (3-MCPD) and 3-MCPD esters were found in any type of refined vegetable oil -mostly produced during the refining process- and recognized as emerging food contaminants. Several analytical methods have been developed and one of which was a Weißhaar's method. The study aims to validate the modified Weißhaar's method for analysis of 3-MCPD and 3-MCPD esters in refined palm oil. Ion fragments were used for identification and quantification of 3-MCPD and 3-MCPD-d5. 3-MCPD was determined by GC-MS after released from its ester by transesterification with sodium methoxide and derivatized with phenylboronic acid. The validation showed that liniarity response (r=0.994) was observed from a linear regression by using external standard and internal standard at a concentration range of 0.008 and 0.377 µg mL-1. The LOD of the validated method was 0.06 µg g-1 while its LOQ was 0.20 µg g-1, precision (relative standard deviation, RSD) was 6.16%, and accuracy (as percentage of recovery) was in the  range of 95.83-113.27%. This results indicated that the modified method was valuable and sensitive for detection of 3-MCPD and 3-MCPD esters. Using the validated method, 3-MCPD esters content of a commercial palm oil sample was determined and calculated as the difference between total 3-MCPD and free 3-MCPD, which was 13.24 µg g-1. Total 3-MCPD content of several palm oils were at a concentration range of 13.94-34.52 µg g-1. These results also showed that there was a correlation between 3-MCPD with diacylglyceride (DAG). Samples with DAG content gave a high test results of 3-MCPD with a coefficient of correlation of r=0.752.
