The Estimation of Non-Protein Nitrogen in Blood by a Micro-Kjeldahl Method.

A Simplified Ultra-micro Kjeldahl Method for the Estimation of Protein and Total Nitrogen in Fluid Samples. of Less Than

Adaptation of the Micro-kjeldahl Method for the Determination of Nitrogen in Plant Tissues.

The micro-Kjeldahl method for nitrogen determination has been widely used in organic chemistry laboratories in recent years. The value of this method, developed through the brilliant researches of PiLcH, BANG, PARNAS and WAGNER, PREGL, and coworkers, has justified its application to industrial and clinical problems. Plant physiologists have not generally adopted quantitative micro-methods for n...

Effect of Protease-loaded Nanoliposome Produced by Heating Method on Yield and Composition of Whey and Curd during the Production of Iranian Brined Cheese

Background and Objectives: Fast proteolysis of cheese in ripening process may lead to the premature attack of casein, release of the majority of enzymes into the whey, and loss of cheese composition from curd to whey. In this study, the effect of liposomal Flavourzyme on proteolysis of Iranian white brined cheese, as well as on the yield and composition of whey and curd was investigated. Mater...

Coulometric Determination of Protein Nitrogen. Application to Direct Titration of Kjeldahl Digests.

A coulometric method is described for the determination of ammonia resulting from micro-Kjeldahl digestion of protein samples. The method has been applied to the direct titration of the ammonia in the digests. Routine titration of the ammonia resulting from lOsl. serum samples is described; the method has been applied to 1 -JLI. samples. Results are compared with standard macroand micro-Kjeldah...

مقایسه روش هچ با روش کجلدال در تعیین محتوای پروتئین خام برخی خوراک های دامی

The aim of present study was to evaluation of Hach method for determining of crude protein contents of some animal feeds. Twenty one samples of animal feeds and digesta, including a variety of forages, concentrate feeds and mixtures and digesta ruminal samples and 0.025, 0.05, 0.075, 0.1, 0.175 and 0.2 mg ammonium chloride were chosen and their nitrogen and protein contents were measured using ...
