Abstract Studies were made of proposed FAO methods for phosphorus in cheese and processed cheese products, citric acid in processed cheese products, and a polarographic method for sucrose in sweetened condensed milk. The FAO methods give precise and accurate results. Collaborative studies are recommended.

Abstract The precision of instruments used in 3 collaborative studies conducted within the Food and Drug Administration over a 4-year period (1981, 1982, 1984) for water activity (a„) determinations according to the official AOAC method is evaluated. Calibration responses of the instruments were tested for linearity over the a„ range from 0.75 to 0.97. Average absolute percent difference between predicted and assigned a, values for the linear model ranged from 0.3 to 0.7% for a fiber-dimensional hygrometer (Abbeon) and 3 electrical hygrometers (Beckman, Rotronics, and Weather Measure). The calibration responses for another electrical hygrometer (Hygrodynamics) were nonlinear. The fiber-dimensional hygrometer yielded mean a„ values and precision estimates that did not differ significantly from those obtained with the electrical hygrometers for (NH4)2S04 slush, KN03 slush, sweetened condensed milk, pancake syrup, and cheese spread. However, the mean a„ value for a soy sauce was 0.838 for the electrical hygrometers compared with 0.911 for the fiber-dimensional hygrometer. The fiber-dimensional hygrometer was affected by a volatile components) in the soy sauce that caused an erroneously high a„ value. Pooled estimates of reproducibility (5X) in the 3 studies were 0.008 for the fiber-dimensional hygrometer and 0.010 for the electrical hygrometers; these values were not significantly different from those reported in the study that verified the current official AOAC method.

<p>Abstrak<br />Produk susu bubuk dan susu kental manis merupakan produk turunan susu, yang banyak dikonsumsi khususnya balita. Kementerian Perindustrian berencana memberlakukan wajib SNI 01-2970-2006, Susu bubuk dan SNI 01-2971-1998, Susu kental manis dalam regulasi teknis pada tahun 2013-2014 untuk melindungi masyarakat dari masalah keamanan pangan dan kesehatan. Sedangkan tujuan dari penelitian ini adalah untuk menganalisa kesiapan pemberlakuan wajib SNI susu bubuk dan susu kental manis dari aspek ketersediaan standar, perdagangan produk (ekspor-impor), infrastruktur penilaian kesesuaian dan efisiensi produksi produk. Diperoleh hasil bahwa ketersediaan standar masih kurang, industri pengolahan susu baik susu bubuk dan susu kental manis masih besar ketergantungan terhadap bahan baku susu impor (perdagangan masih negatif) dan infrastruktur masih kurang memadai sehingga efisiensi masih rendah. Program pengembangan standar nasional untuk produk susu perlu ditingkatkan dan dilengkapi untuk meningkatkan kualitas produk olahan susu dengan mengadopsi dari standar internasional atau standar nasional negara lain dan harus mempertimbangkan kondisi dan kebutuhan masyarakat di Indonesia. Pengembangan lembaga penilaian kesesuaian perlu disesuaikan dengan arah kebijakan pemerintah diselaraskan dengan daerah pengembangan sentra susu dan industri dalam menunjang penerapan pemberlakuan wajib SNI susu bubuk dan susu kental manis di Indonesia.<br />Kata Kunci: susu bubuk, susu kental manis, Standar Nasional Indonesia (SNI).</p><p><br />Abstract<br />Powder Milk and condensed milk are derivative products, which are widely consume, especially by toddlers. Ministry of industry has plans to impose mandatory SNI 01-2970-2006, Powder Milk and SNI 01-2971-1998, Sweetened condensed milk in Technical Regulations 2013-2014 to protect the public from food safety and health issues. The purpose of this study is to analyze the readiness of implementation of mandatory SNI powder milk and condensed milk from availability of related standards, import-export trade, conformity assessment infrastructure and the efficiency of production. The results obtained indicate that the availability of related standards are deficient, dairy processing industries (for powder milk and sweetened condensed milk) have great dependency on imports of raw milk (negative trading), and the infrastructure is inadequate; as a result the efficiency is low. Development program of national standards for dairy products needs to be improved and equipped to improve the quality of dairy products by adopting international standards or national standards of other countries and should take into consideration the conditions and market needs in Indonesia. Development of conformity assessment bodies need to be adapted to the direction of government policy, is aligned with regional development centers and industrial milk in supporting the implementation of the implementation of mandatory SNI milk powder and SNI sweetened condensed milk in Indonesia.<br />Keywords: milk powder, condensed milk, National Indonesian Standard (SNI).</p>

Heat treatment is applied to dairy products to ensure microbiological quality and increase the shelf life. However, a suitable control of this process is necessary to guarantee nutritional and sensory quality. The aim of this study is to adapt the high performance liquid chromatography (HPLC) method for determination of lactulose and lactose content in commercial samples of UHT and sweetened condensed milk. The HPLC method used showed a good resolution of the analytes evaluated. The analyzed UHT milk samples presented levels for lactulose in accordance with the limit recommended by the International Dairy Federation. There was no significant variation in lactulose concentration for sweetened condensed milk samples. However, one sweetened condensed milk sample showed lactose level lower than the established values (10–12%).
