White shrimp (Litopanaeus vannamei) is one of the most popular seafood commodities, therefore, it has considerab le economic value. The aim of this study was to evaluate the effect of polyphosphate and sodium chloride addition in the soaking solution on the water holding capacity (WHC) of frozen white shrimp at a pilot scale (i.e. 12 kg), production cost efficiency and its sensory acceptance. Various comb inations of salt and phosphates concentration were evaluated to ob tain the most optimum condition for increasing the frozen shrimp WHC while the final product phosphate residue did not exceed 0.5%. The highest WHC was ob tained b y soaking the white shrimps in a solution containing 2.5% polyphosphate MTR 80-P and 1.0% NaCl. The phosphate residue concentration determined in the final product was ab out 0.27%. The final product multisample difference test (rating test) also confirmed that this comb ination was not detrimental to the perception of the consumers. Moreover, the use of soaking condition reduced the production cost (b ased on the raw material costs) b y Rp. 4.580,900/2.000 kg finished products or equals to Rp. 2.290/kg finished products. Conclusively, the addition of polyphosphate and salt in soaking solution at the optimum concentration increased the WHC of the frozen white shrimps, reduced production cost without changing the product sensory acceptance.

Dodol merupakan salah satu makanan tradisional Indonesia yang menggunakan tepung beras ketan sebagai bahan baku utamanya.  Proses pengolahan dodol secara tradisional memiliki keunggulan dapat menghasilkan dodol dengan tekstur dan umur simpan yang lebih baik dibandingkan dodol komersial. Namun membutuhkan waktu yang lama dalam proses pengolahannya, tenaga kerja yang banyak, dan biaya produksi yang tinggi. Oleh karena itu, berbagai upaya dilakukan untuk memodifikasi pembuatan dodol guna mempersingkat proses pemasakan, menghemat biaya dan memperbaiki kualitas dodol.  Termasuk juga mengendalikan faktor-faktor yang mempengaruhi kualitas dodol seperti bahan baku, proses pengolahan dan pengemasan. Dodol juga merupakan produk yang memiliki kandungan gizi yang relatif rendah dengan kadar gula yang tinggi sehingga tidak direkomendasikan bagi penderita diabetes melitus. Berbagai penelitian yang mengarah pada upaya perbaikan nilai gizi dalam mewujudkan dodol sebagai pangan yang sehat telah banyak dilakukan.  Tulisan ini menyajikan review berbagai upaya dan penelitian untuk berbagai tujuan di atas.Kata kunci : Dodol, makanan tradisional, nilai gizi, teknologi pengolahan

Cassava-rice ratio and cooking time-temperature combinations in baked and fried simulated chips making enriched with carrot, celery, curry leaves and skim milk were studied using completely randomized design. Research found that interaction between mix formula and cooking methods was significantly affected (p<0.05) the physical, sensorial and chemical characteristic of the simulated chips. The best baked simulated cassava-rice simulated chips was resulted from 80:20 ratio, baked at 140 ºC for 14 minutes, and the fried cassava-rice simulated chips with 60:40 ratio fried at 150 ºC for 2.5 minutes. The fried chips have finer microstructure and more preferable than the baked one. However, both best chips were potential to be further developed.

Broken and brewer rice as by product of rice milling can be developed into a functional product with higher economic value, i.e. higher resistant starch (RS) rice flour. This research was aimed to study the modification of broken and brewer rice flour by the combination of microwave and ultrasonication with heat moisture treatment (HMT) to enhance RS contents and its associated microstructural and pasting characteristics changes. The results showed that five modified rice flours that had the highest RS contents

Abstract:The study was aimed to obtain the optimum conditions for vacuum frying and predicting the moisture lost during rice straw mushrooms stem chip production. The raw materials were obtained from the local farmer around the campus. A completely randomized factorial experimental design and Duncan's multiple range tests were used to achieve the objectives. Three temperatures, i.e. 80, 90 and 100 °C and five frying time, i.e. 3, 6, 9, and 15 minutes with a 2 mm slice thickness were studied to determine the optimum condition and predict the moisture decrease. Results showed that t he vacuum frying time in general affects the chips color and oil uptake significantly (p < 0.01) and correlated with the moisture decrease. The chips moisture content decline significantly after vacuum frying at 90 °C and 100 °C for 3 minutes. While for the 80 °C vacuum frying, the significant decrease of moisture occurred due to the increase of vacuum frying time from 3 to 6 minutes (p < 0.01). The optimum conditions for a 2 mm slice thickness chips making are vacuum frying at 100 °C for 3 minutes. The chips moisture lost followed generally a two-stage of falling rate pattern during vacuum frying, and each could be well predicted by an exponential equation (R 2 = 0.99).
