Abstract

Soybean is a strategic commodity which is used as a raw material for food processing and consumed by most of Indonesian people. National demand cannot be covered by local production, due to imported one. This research indicated that soybean harvested area was influenced by local soybean real price, maize real price and last year harvested area. Soybean productivity was influenced by rainfall, maize real price and last year productivity. Local soybean price was influenced by soybean real price at producer level, imported soybean real price, quantity of imported soybean, productivity and last year soybean real price. Soybean real price at producer level was influenced by soybean production, imported soybean quantity, soybean consumption, BULOG monopoly and last year real price at producer level. Soybean import quantity was influenced by production and consumption. Imported soybean price was influenced by international price, exchange rates, import tariff, and last year import price. Combination policy of increase the soybean price and import tariff 20% would stimulate the producer to increase harvested area and production. Strategy to increase competitiveness and national soybean production are through productivity improvement and extended planting area programs. The priority to increase the production is to improve productivity and apply suitable technology. Extension of planting area to better region is conducted to increase cropping index. To anticipate trading liberalization negative effect to farmers’ welfare, protection policy by the government is still needed to control international price fluctuation and to strengthen local soybean competitiveness. Keywords: Strategic commodity, productivity, real price, import quantity, soybean

Abstract

Talas Beneng (Xanthosoma undipes K.Koch) merupakan sumber pangan lokal khas Banten yang banyak tumbuh di Kabupaten Pandeglang. Sebagian besar Talas Beneng diolah menjadi tepung dan dijual untuk digunakan sebagai bahan baku pembuatan produk bakery. Akan tetapi masih terdapat masalah dengan produk tepung ini, yaitu karakteristiknya tidak stabil dan mempunyai kandungan asam oksalat yang cukup tinggi yang dapat menimbulkan rasa gatal saat dikonsumsi. Tujuan penelitian ini adalah untuk memperbaiki kualitas produk tepung talas beneng melalui introduksi perlakuan proses yang baru, yaitu penghilangan tahapan perendaman. Parameter yang diamati adalah karakteristik fisik dan kimia tepung Talas Beneng yang dihasilkan dari produksi komersial (dengan perendaman) yang diproduksi oleh kelompok tani dan introduksi perlakuan proses baru (tanpa perendaman). Data yang diperoleh dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa introduksi proses perlakuan tanpa perendaman menghasilkan tepung dengan karakteristik kimia yang lebih baik, yaitu kadar abu, kadar karbohidrat dan serta pangan yang lebih tinggi, dan kadar air dan kadar oksalat yang lebih rendah. Warna tepung talas beneng yang dihasilkan mempunyai nilai a* dan b* yang lebih rendah, sedangkan nilai L* nya lebih tinggi dibanding produk tepung Talas Beneng komersial. Granula pati tepung Talas Beneng yang dihasilkan dari kedua proses tersebut berbentuk poligonal.

Abstract

Premix kernel as fortificant on the rice fortification has a very important role for the success of the fortification program. The important aspect of premix kernel besides the uniformity of micronutrient content is also mostly determined by its physical and sensory properties. The aims of this study were to determine the effect of process temperature and water addition to the physical and sensory properties of the premix kernel produced. The experiment used a factorial completely randomized design with factor (1) extruder temperature (90, 95, and 100oC) and factor (2) water addition (35, 40, and 45%). Premix kernel (1 kg) was made from rice flour (800 g), sago starch (200 g), glycerol monostearate (20 g), and iron (7000 mg) using hot extrusion technology. The results showed that the process temperature had a significant effect on the parameter of brightness, hue, length, width, and thickness of the premix kernel, while the addition of water had significant influence on all aspects of the tested parameters including brightness, hue, 1000-grain weight, length, width, and thickness of the premix kernel. Interaction of process temperature and addition of water also have a significant effect on hue parameters, 1000-grain weight, length, width, and thickness of the premix kernel. The interaction of process temperature and addition of water also significantly influenced the hue parameter, 1000-grain weight, length, width, and thickness of the premix kernel. The combination of 90°C process temperature treatment and 40% water addition produced the highest frequency for all test parameters. The triangle test showed that panelists could not distinguish the fortified rice with commercial rice in the form of both cook and uncooked rice.

Abstract

Purple sweet potato is rich in anthocyanin giving a potential application in food product development.  However, anthocyanin is relatively unstable and easily degraded during processing and storage. Understanding the stability and bio-accessibility of anthocyanin during processing, storage and simulated digestion is very important. The study aimed to investigate changes in anthocyanin degradation during processing, storage and simulated digestion of purple sweet potato pasta. The pasta was prepared through several processing steps, i.e. steaming the tuber, steaming the dough formula, extrusion, drying and boiling. Anthocyanin was analyzed at every stages of processing and storage of the pasta. The durability of the pasta during storage was analysed using an accelerated shelf-life testing method at 30, 40 and 50ºC for 28 days. The study showed that anthocyanin content decreased during the whole stages of processing and storage, but slightly increased during steaming. The highest loss of the anthocyanin occurred in the boiling process. Based on resistance to stomach and intestinal conditions, the bio-accessibility of anthocyanin was better in the digestive system in the stomach than that in the intestines. The increased anthocyanin appeared again in the colon. This study provides useful information for designing an effective method to minimize an extensive loss of anthocyanin of purple sweet potato for food product development.
