Advisor: Nguyen V inh Tien, PhD. Content of the project: Examining the characteristics of chitosan films with 0 – 9% levels of cinnamldehyde: UV – Vis absorption spectrum and optical transmittance, equilibrium moisture content, water uptake, water solubility, tensile strength, elongation – at – break, water vapor permeability, antioxidant activity, in vitro antibacterial and antifungal activities, and in vivo antifungal activity on limes. Strengths: A high work load with a wide range of experimental techniques used to characterize the chitosan films incorporated with 0 – 9% cinnamaldehyde. In vivo antifungal tests of chitosan – 7 – 9% cinnamaldehyde on limes are promising.
Weaknesses: modern characterization techniques (XRD, FTIR, TGA, DSC) were not utilized to reveal structural changes in chitosan films after incorporating cinnamaldehyde. Approval for oral defense? Approved 5. Overall evaluation: Good 6.1/10 (in words: nine point one) Ho Chi Minh City, December 26th, 2021 ADVISOR (Sign with full name) 4 THE SOCIALIST REPUBLIC OF VIETNAM Independence – Freedom– Happiness -------- Ho Chi Minh City, December 28, 2021 PRE-DEFENSE EVALUATION SHEET Student name: Tran Thi Van An Student ID: 171 16001 Student name: Vu Thi Thu Huong Student ID: 17116012 Major: Food Technology Project title: Active packaging based on chitosan and cinnamaldehyde for meat and fruit. Name of Reviewer: Nguyen Quang Duy, M.
Content and workload of the project: Examining the characteristics of chitosan film samples with varying levels of cinnamaldehyde: UV – Vis absorption spectrum and optical transmittance, equilibrium moisture content, water uptake, water solubility, tensile strength, elongation – at – break, water vapor permeability, antioxidant ability, antibacterial and mold resistance of chitosan – cinnamaldehyde film on meat and fruit. Strengths: The project has clear objectives and appropriate methods to achieve the results. The English used in the report is academic and adequate. The project used modern analytical techniques to obtain and analyze the data.
Weaknesses: The authors should use the word "investigation" instead of "survey" in the report. The authors should extend the range of CNM concentration. Questions: Question 1: Why did the authors choose the concentration of CNM solutions in this research from 1 to 9% (v/v)? Question 2: Why did the authors study the antioxidant activity of CH – CNM films? Do you think that it would give better results in terms of antioxidant and antimicrobial activities if the concentration of CNM increased to more than 9% (v/v)? 5 4. Approval for oral defense? (Approved or denied) Approved.
Overall evaluation: (Excellent, Good, Fair, Poor) Good.
