Cocoyam Used as Substitute of Cassava in the Preparation of Starch Based Biofilms and Biocomposites by Casting Method

Cocoyam Used as Substitute of Cassava in the Preparation of Starch Based Biofilms and Biocomposites by Casting Method

3 Université de Kairouan - Av. Med Ibn Sahnoun, 3100 KAIROUAN (Tunisia) Abstract— Cassava starch is used extensively to produce isotropic, odorless, tasteless, colorless, non-toxic and biologically degradable films. The similarity in composition, mineral content, microscopic, thermal, physicochemical and rheological properties between cassava and cocoyam starches being reported in literature, it is expected that, cocoyam could be used to increase the supply in equivalent starch. In this work, the possibility to replace cassava by cocoyam starch in the preparation of biomaterials is investigated. In this aim, the preparation of biofilms without and with 2 and 3D mineral fillers by casting method is brought out in one hand with cassava and in the other hand, with cocoyam. The water barrier and the mechanical characteristics of the films obtained with cocoyam starch are compared to those prepared with the same method but using cassava starch. The results show that cocoyam starch based films exhibit poor water barrier and mechanical characteristics due to its brittleness, which have been improved by the use of fillers.

Development and Validation of a Stability Indicating HPLC Method for the Analysis of Desvenlafaxine Succinate in the Presence of its Acidic Induced Degradation Product in Bulk and Pharmaceutical Preparation

Development and Validation of a Stability Indicating HPLC Method for the Analysis of Desvenlafaxine Succinate in the Presence of its Acidic Induced Degradation Product in Bulk and Pharmaceutical Preparation

Elution was carried out using acetonitrile: phosphate buffer pH 3.8 (50 : 50 v/v) as a mobile phase at a flow rate of 0.7 ml/min and UV detection at 229 nm. The linear regression analysis data for the calibration plots showed good linear relationship in the concentration range 5-100 µg/ml (r 2 =0.9999). The values of slope and intercept were 34.295 and 12.564 respectively. The method was successfully validated in accordance to ICH guidelines acceptance criteria. The specificity and stability-indicating capabilities of the method was verified by subjecting DSV to acid hydrolytic stress condition. The acid degradation product was confirmed as 4-(1- cyclohexenyl-2-(dimethylamino)ethyl)phenol. Under the chromatographic condition, the degradation product was well resolved from the active pharmaceutical ingredients with significantly different retention time. Thus the proposed method was found to be stability- indicating and can be used for routine analysis of the drug without interference of acidic degradation product. The proposed method was successfully applied for the analysis of pharmaceutical formulation. The validity of the suggested procedures was further assessed by applying the standard addition technique which was found to be satisfactory. The results were statistically analyzed and compared with those obtained by the reported method.

Starch Nanoparticles – Two Ways of their Preparation

Starch Nanoparticles – Two Ways of their Preparation

Czech J. Food Sci., 36: 133–138. Starch nanoparticles (SNP) originate from the disruption of the semi-crystalline structure of starch granules. They are very useful in food packaging technology because they increase the mechanical and water vapour resistance of the matrix as well as hinder its recrystallisation during storage in high humidity atmospheres. In medicine, SNP are suitable as carriers in modulated drug delivery for immobilized bioactive or therapeutic agents. Depending on the method of preparation, nanoparticles with different physicochemical, technical or mechanical properties can be obtained. Two different methods of preparation were characterized and compared in this work: the first involving acid hydrolysis of the amorphous part of a starch molecule and the second focusing on the debranching of starch by enzymatic treatment with pullulanase.

PREPARATION AND EVALUATION OF STARCH PHOSPHATE- A NEW MODIFIED STARCH AS A DISINTEGRANT IN TABLET FORMULATIONS

PREPARATION AND EVALUATION OF STARCH PHOSPHATE- A NEW MODIFIED STARCH AS A DISINTEGRANT IN TABLET FORMULATIONS

University College of Pharmaceutical Sciences, Andhra University, VISAKHAPATNAM – 530003 (A.P.) INDIA ABSTRACT Starch phosphate prepared by reacting potato starch with di-sodium hydrogen orthophosphate anhydrous at elevated temperatures was found to be a white, crystalline, non-hygroscopic powder. Starch phosphate prepared exhibited excellent flow characteristics. Starch phosphate was insoluble in water and aqueous fluids of acidic and alkaline pHs. It also exhibited good swelling (400%) in water. It has no pasting or gelling property when heated at 100 o C in water for 30 min. As starch phosphate exhibited good swelling in water, it is considered as a promising disintegrant in tablet formulations and was evaluated as disintegrant in tablet formulations. Tablets of (i) sulfamethoxazole (100 mg) and (ii) paracetamol (120 mg) were prepared by wet granulation method employing starch phosphate at 5 and 10% strength as disintegrant and were evaluated. For comparison tablets were also prepared employing crospovidone (a super disintegrant) as disintegrant at 5 and 10% strength in the tablets. Paracetamol and sulfamethoxazole tablets formulated employing starch phosphate (both wet and dry addition) disintegrated within 3 min.

Preparation, characterization, and evaluation of sorghum flour with increased resistant starch content

Preparation, characterization, and evaluation of sorghum flour with increased resistant starch content

40 sample (Brewer, Cai, & Shi, 2012). Which method provides a similar in-vitro starch digestion most similar to the human digestive system is at question. Sorghum is more complicated to test for RS content than other grains. Its low protein and starch digestibility is unique among cereals. By testing with Englyst method, RS content of sorghum flour is high without efficient protease treatment (Xu, 2008). In fact, sorghum protein may act as a barrier to protect sorghum starch from enzymatic hydrolysis. The removal of sorghum protein by protease pretreatment helps expose the starch to digestive enzymes and is necessary to produce accurate results. A modified Englyst method with a longer time of protease treatment (2 h instead of 30 min) and different pH (2.0 instead of 1.3) was previously used to determine RS content of sorghum flour (Xu, 2008). The integrated TDF method, however, does not include a pepsin pretreatment step. Heat treatment was successful in increasing RS content of sorghum flour when evaluated by Englyst method (Chapter 1). The objectives of this chapter were to evaluate starch digestion of sorghum flour with and without heat treatment, and to investigate if a pepsin pretreatment step is needed in the integrated TDF method for testing RS content of sorghum flour.

Determination of mercury species in foodstuffs using LC ICP MS: the applicability and limitations of the method 

Determination of mercury species in foodstuffs using LC ICP MS: the applicability and limitations of the method 

The chromatographic resolution of methylmercury and inorganic divalent mercury peaks is sufficient even if a trace amount of one species is present in a large excess of the other. The ICP-MS detection is specific and sensitive enough to quantify mercury species at lower ng/g levels. To achieve reliable results, a proper calibration is necessary; fresh calibration solutions should be prepared on a daily basis. Moreo- ver, any source of sample contamination should be eliminated or minimised. Therefore, we kept the way of sample preparation very simple. As a ubiquitous element in chemical laboratories, mercury is prone to contaminate the samples, especially as inorganic divalent mercury. All chemicals should be checked for impurities of mercury. The precautions against contamination include namely a thorough cleaning of disposables (filters and syringes) and centrifuge tubes, which are used for sample extraction, and the insertion of an injection blank before each sample injection. In addition, several procedure blanks have to be included in each sample series.
