Background: Evaluation of the nutritional composition of genetically modified (GM) crops is mandatory for their deregulation. Chickpea is known for its high-quality protein and demonstrating that the seed protein quality of transgenic chickpea remains unaltered is important for its acceptance. Amino acid content, seed storage protein profile and the digestibility of chickpea protein are important determinants of seed protein quality. Thus, in the present study, we assessed the effect of Bt (Cry2Aa) gene expression on the Bt chickpea seed protein quality. Methods: We assessed the amino acid profile, in vitro protein digestibility and factors affecting protein digestibility like trypsin inhibitor, tannins and phytic acid contents of the transgenic Bt chickpea expressing a codon modified Cry2Aa gene and its non-transgenic counterpart. Furthermore, the seed storage proteins were also fractionated and separated on SDS-PAGE followed by mass spectroscopy of the major peptides. Result: Amino acid profile and factors affecting protein digestibility revealed no significant variations between transgenic and non-transgenic chickpeas. Seed storage protein profile confirmed the presence of legumin, vicilin and albumin. No potential change in the digestibility pattern of seed proteins was revealed. Our findings suggest no potential unintended changes in chickpea seed protein quality due to the expression of Cry2Aa gene.

This study applied SERVQUAL scale of Parasuraman et al to measure factors affecting customer satisfaction on service quality at Vietnam Technological and Commercial Joint Stock Bank - An Giang Branch (Techcombank An Giang). The study was conducted to survey 207 customers who have been using the service at Techcombank An Giang. The survey results were analyzed by the Cronbach's Alpha reliability test method, then used Exploratory factor analysis (EFA) to verify and evaluate the scale of service quality. The results of the regression analysis show that customer's satisfaction about service quality at Techcombank An Giang includes four factors: The factor with the highest level is the Empathy with Beta = 0.253, the second of factor is the Responsibility with Beta = 0.248, ranked third in the influence level is the Tangible with Beta = 0.235, and the lowest impact level is the Reliability with Beta = 0.144. The research also uses statistical methods to describe and test the differences of demographic factors with customer's satisfactionon service quality.The analysis results show that there is no difference between customer's satisfaction on service quality and factors such as gender, age, income, number of transaction banks, regular transaction banks, and time to use the service at Techcombank An Giang. Through the research results, the author would like to propose some ideas to improve the quality of services, thereby attracting new customers and importantly, keeping traditional customers because the development orientation of Techcombank is to take care of old customers to cross sell other products of the bank. The Stud results offer a basis for the branch to identify the factors influencing customer satisfaction on their service quality, thereby having an appropriate strategy to improve customer satisfaction.

Sugar palm (Arenga pinnata) is a feather palm native to tropical Asia. In Vietnam, it is named Búng Báng or Đoác and grown only on the highlands in the central or northern part of Vietnam. It is utilized for many purposes, especially for Ta Vat wine production - a characteristic and unique product of Co Tu ethnic minority. However, because of the natural fermentation used in the production, the product quality is inconsistent. The purpose of this study was to examine a new procedure of using palm sap for making Ta Vat wine. Some characteristics of the sap, which was collected at Nam Giang district, Quang Nam province are determined, proving the potential of the sap for making wine product. The quality of sap changes quickly at room temperature. At low temperature (4 - 60C), the changes in sap quality are apparently slower. Examining some factors affecting its quality during the wine fermentation process, we determined the best parameters for the fermentation process as follows: inoculum size of 3% with cell density of about 1x108 cells/ml, the addition of the extract from the bark of Ceylon ironwood (Mesua ferrea L.) 4%. Keywords: Arenga pinnata, sap, Ceylon ironwood bark, Mesua ferrea L., wine fermentation.
