The addition of red palm oil in palm sugar will affect the content and retention of carotene as well as physical and sensory properties of the product during storage which were also influenced by packaging types. This study aimed to evaluate the changes in physical, chemical and carotene retention during storage of palm sugar. Palm sugar enriched with red palm oil was made by addition of two types of red palm oil (CPO and RPO ) and the amount of the addition (30 ml , 60 ml and 90 ml ) / 10 L coconut sap, after that packed with a single packaging (polypropylene, PP) and doublepackaging (PP + brown paper ) and stored for 2 months. After stored for 2 months, the level of total carotenoids of coconut palm sugar enriched with RPO decreased between 4.99 to 49.79 % with carotene content between 703 µg/100g up to 13383 µg/100 g. The decreased level of total carotene in first month and second month storage of coconut palm sugars enriched with RPO was higher (17.48 % and 24.47 %) compared to coconut palm sugar enriched with CPO (7.47% and 12.95 %) (p<0.05). The use of double packaging (polypropylene plastic + brown paper) is able to inhibit the decrease in total carotenoid up to 4.00 % to 6.67 %, better than the single packaging. The longer the storage, moisture content of product increased. However, after stored up to 2 months, the water content in all treatments was in range of SNI-01-3743-1995 standard (< 10 %) which is between 8.55 % up to 9.94 %.Keywords: Red palm oil, carotene retention, coconut palm sugar, storage, packaging ABSTRAKPenambahan minyak sawit merah pada gula kelapa akan berpengaruh terhadap kandungan dan retensi karoten, serta sifat fisik dan sensori produk selama penyimpanan yang juga dipengaruhi oleh jenis pengemas. Penelitian bertujuan untuk mengevaluasi perubahan sifat fisik, kimia dan retensi karoten selama penyimpanan gula kelapa. Gula kelapa yang diperkaya minyak sawit merah dibuat dengan penambahan dua jenis minyak sawit merah (CPO dan RPO) dan jumlah penambahannya (30 ml, 60 ml dan 90 ml) / 10 L nira kelapa, serta dikemas dengan pengemas tunggal (plastik polypropilene/PP) dan pengemas ganda (plastik PP + kertas coklat). Makin lama penyimpanan terjadi penurunan kekerasan tekstur, retensi dan kadar total karoten, sebaliknya untuk parameter kadar air dan kadar gula reduksi terjadi peningkatan. Setelah disimpan selama 2 bulan, kadar total karoten gula kelapa yang diperkaya karoten dari CPO maupun RPO turun antara 4,89 % - 49,79 % dengan kadar karoten antara 703 µg/100 g – 1338,3 µg/100 g. Makin banyak jumlah penambahan CPO maupun RPO, persentase penurunan total karoten selama penyimpanan makin kecil. Penurunan kadar total karoten bulan ke-1 dan ke-2 pada gula kelapa yang diperkaya RPO lebih tinggi (17,48 % dan 24,48 %) dibandingkan gula CPO (7,47 % dan 12,95 %) (p<0.05). Penggunaan pengemas ganda plastik polypropylene dengan kertas coklat (payung) mampu menghambat penurunan total karoten hingga 4,00 % sampai 6,67 % lebih baik dibandingkan pengemas tunggal. Makin lama penyimpanan, kadar air produk makin meningkat. Namun demikianhingga penyimpanan selama 2 bulan, kadar air produk pada semua perlakuan masih dalam kisaran standar SNI-013743-1995 (< 10 %), yaitu antara 8,55 % - 9,94 %.Kata kunci: Minyak sawit merah, retensi karoten, gula kelapa, penyimpanan, pengemas

Cake rusks were prepared by using different combinations of normal and red palm oil fortified shortening to explore the possibility of red palm oil (RPO) fortified shortening to enhance the vitamin A status in human dietary intake. The replacement of normal shortening with RPO up to 50% level was the most acceptable, however, the use of RPO shortening beyond this limit showed a somewhat oily after taste. Carotenoid contents in flour, normal shortening, RPO shortening and egg were 3.57 ppm, 5.85ppm, 405.39 ppm and 5.13 ppm, respectively. Moisture content increased from 3.11% to 3.22% after 28 days of storage. During baking, loss of carotenoid contents ranged from 12.07% to 14.91%. A minimum carotenoid content of 7.19 ppm were found in the cake rusks (T1) prepared with 100% normal shortening (NS) while a maximum of 105.64 ppm was observed in (T5) 100% RPO in the freshly prepared product. The mean carotenoid content in T3 (50% RPO 50% NS) was 57.80ppm however it ranged from 6.94ppm (T1) to 102.34 ppm in (T5). A gradual decrease (7–10%) in carotenoid contents during 28 days’ storage was observed. There was significant increase (0.04–0.08 mg malonaldehyde/kg) in thiobarbituric acid number during storage. Results regarding sensory attributes reflect that T3 comprising of 50% RPO and 50% NS got the highest score. Furthermore consumer response in the acceptability study also showed that T3 treatment of cake rusk is suitable for commercialisation.

Beta-carotene-rich fat powder was prepared from the mixture of red palm oil/RPO (olein and stearin) and fully hydrogenated palm oil/FHPO by using spray chilling process. Effects of composition of fats used on fat powderflowability, were studied. Our research showed that spray chilling process may be used to produced β -carotene rich-fat powder. Our result also indicated that the use of higher composition of RPO to increase β-carotene content of fat powder tend to reduce the flowability of the resulting fat powder. The maximum ratio of RPO/FHPO used to produce free flowing fat powder was 50% (formula of F50) with β-carotene content of 167.71 ppm. Our research also showed that the melting point of molten mixture fat used was significantly correlated with flowability of the resulting fat powder. The higher melting point of molten fat, the lower the angle of repose or the better flowability of fat powder produced.Keywords: Fat powder, β-carotene, spray chilling, flowability ABSTRAKLemak bubuk kaya β-karoten telah dibuat dengan menggunakan campuran minyak sawit merah (MSM) fraksi olein dan stearin, serta minyak sawit terhidrogenasi penuh (FHPO) melalui proses pendinginan semprot. Penelitian ini dilakukan untuk melihat pengaruh komposisi campuran minyak tersebut terhadap karakteristik lemak bubuk yang dihasilkan, terutama sifat daya alir. Hasil penelitian menunjukkan bahwa proses pendinginan semprot bisa menghasilkan lemak bubuk kaya β -karoten. Penelitian ini juga menunjukkan bahwa peningkatan rasio MSM untuk meningkatkan kadar β-karoten akan menurunkan daya alir lemak bubuk yang dihasilkannya. Rasio maksimal MSM/FHPO yang dapatdigunakan untuk menghasilkan lemak bubuk yang mudah mengalir diperoleh sebesar 50/50 (formula F50), dimana lemak bubuk tersebut mempunyai kadar β-karoten sebesar 167.71 ppm. Titik leleh bahan lemak berkorelasi kuat dengan daya alir lemak bubuk yang dihasilkan, dimana semakin tinggi titik leleh akan menghasilkan lemak bubuk dengan daya alir yang lebih baik, yang ditunjukkan dengan sudut gulir yang lebih rendah.Kata kunci: Lemak bubuk, β-karoten, minyak sawit merah, pendinginan semprot, daya alir

Alginate-based microencapsulation of live cells may offer the opportunity to treat chronic and degenerative disorders. So far, a thorough assessment of physical-chemical behavior of alginate-based microbeads remains cloudy. A disputed issue is which divalent cation to choose for a high performing alginate gelling process. Having selected, in our system, high mannuronic (M) enriched alginates, we studied different gelling cations and their combinations to determine their eventual influence on physical-chemical properties of the final microcapsules preparation,in vitroandin vivo. We have shown that used of ultrapure alginate allows for high biocompatibility of the formed microcapsules, regardless of gelation agents, while use of different gelling cations is associated with corresponding variable effects on the capsules’ basic architecture, as originally reported in this work. However, only the final application which the capsules are destined to will ultimately guide the selection of the ideal, specific gelling divalent cations, since in principle there are no capsules that are better than others.

Physical, chemical, and isotopic analyses of individual radioactive and other particles in the micron-size range, key tools in environmental research and in nuclear forensics, require the ability to precisely relocate particles of interest (POIs) in the secondary ion mass spectrometer (SIMS) or in another instrument, after having been located, identified, and characterized in the scanning electron microscope (SEM). This article describes the implementation, testing, and evaluation of the triangulation POIs re-location method, based on microscopic reference marks imprinted on or attached to the sample holder, serving as an inherent coordinate system. In SEM-to-SEM and SEM-to-SIMS experiments re-location precision better than 10 μm and 20 μm, respectively, is readily attainable for instruments using standard specimen stages. The method is fast, easy to apply, and facilitates repeated analyses of individual particles in different instruments and laboratories.
