Lyophilization of Giloy stem
In traditional Indian medicine, Giloy is one of the most useful ayurvedic herb. Freeze drying is evaluated as a drying method in order to preserve Giloy properties. Freeze drying is known to be one of the most appropriate method for the preservation of natural and biological materials thanks to the oxygen free environment and the low operating temperatures.
Nitrogen and Protein Determination in Animal Feed according to the Kjeldahl method
The determination of protein in feed is a routine procedure for quality assurance and labelling. A simple and fast method for protein determination in feed products according to the ISO 5983-2:2009 and AOAC 954.01 regulations is introduced below. The sample is digested with sulfuric acid and Kjeldahl Tablets Titanium using the digest Automat K-438, followed by distillation and titration with the KjelMaster K-375 with KjelSampler K-376.
Nitrogen Determination in Pharmaceutical Active Peptides
Nitrogen and total protein determination in pharmaceutical products are described in the European Pharmacopoeia (Ph.Eur.) section 2.5.9 and 2.5.33 method 7 [1, 2]. In the Pharmacopoeia of the United States (USP), nitrogen determination is described in section 461 [3]. Therein, different titration techniques are specified. The Ph.Eur. describes back titration in the presence of the indicator methyl red mixed solution and the USP potentiometric boric acid titration.
Monitoring the Degumming Step of Crude Oils
The implementation of a BUCHI NIR-Online® process sensor after the degumming step provides full quality control of degummed oil. Within milli-seconds, different parameters such as phosphorus, moisure or free fatty acids, are continuously, simultaneously, and accurately measured with NIR.
