Learning outcomes of the course unit

MODULE 1: Learning outcomes of the course will be the acquisition of a language formally correct regarding the course program in relation to the concept of food quality and quality control. Increase of the ability to express the content related to the steps of the food processes in a clear and straightforward manner, the ability of connections between the different parts of the course and between processes and operations of the food industry.
In addition, the student will gain expertise in the field of wine, pasta and vegetable products technology in order to show capacity to solve technological problems related to processes and products in these topics. MODULE 2: Learning outcomes of the course will be the acquisition of a language formally correct regarding the topics covered, particularly in relation to the concept of food quality and quality control, the ability to express the content related to the steps of the food processes in a clear and straightforward manner, the ability of connections between the different parts of the course and between processes and operations of the food industry. In addition, the student will gain expertise in the field of fat and meat product technology in order to present ability to solve technological problems related to processes and products in these topics during his/her future employment or during the attendance of an advanced degree courses in the same areas

Prerequisites

Basic knowledge on unit operations, food chemistry and food microbiology are requested

Course contents summary

MODULE 1: Fruit and vegetable processed products. Blanching and thermal treatments. Grain milling and pasta technology. Drying of foods. Food packaging and related technical meterials (paper, glass, plastics and metal cans. Polymer permeability and technical data. Wine making techniques. Haccp rules and applications. Cleaning and sanitation of processing lines. Waste recycling in the food industries. MODULE 2: In the first part of the course, the teacher will supply to the students a complete knowledge about the oil and fat technology explaining in detail all the steps of processing from raw materials to finished products.
In addition, detailed notions will be given on main fats and oils used in the food industry and their applications in various fields of food technology emphasizing their importance and their properties in these areas. Technological innovation in this field will be further discussed in this part of the course.
In the second part of the course, the teacher will discuss some meat products such as cooked products and raw cured products from the traditional Italian gastronomy, explaining in detail all the processing steps from raw materials to finished products.
In the third part of the course, the teacher will give fundamental notions about the concept of food quality in its various meanings. The biological, chemical and physical agents that may affect the food quality will be also discussed as well as the ISO rules

Teaching methods

Class lessons, guided tours, lab experience. The course will consist of teacher lectures and of seminars of addicts from food industry in the area of food technology.

Assessment methods and criteria

MODULE 1: The final exam is in the written form. From the answers given by the student, the teacher tests his/her ability to understand the different steps of food processing and the connections between these various steps. In addition, specific questions by the teacher will be proposed. From responses the teacher will assess the understanding of the principles of food technology and quality management applied to processes and products covered in the course.
The teacher will assess the degree of understanding of the subject by the completeness of the responses and the ability of the student to establish connections between the various topics giving a score commensurate with the expressed understanding and capabilities that will be the score achieved for the overcoming of the module. The final score of the course will be the arithmetic mean of the scores of the two modules.
The teacher will continously asks questions to the students during the lessons to understand the extent of comprehension of the class. MODULE 2: The final exam is a written exam. The written text consists of 5-7 questions about general topics relating to the whole program of the course. From the answers given by the student, the teacher tests his/her ability to understand the different steps of food processes topic of the course and the interconnections between these various steps. In addition, specific questions will be also present in the examination text from whose responses the teacher will assess the understanding of the principles of food technology and quality management applied to processes and products covered in the course. The teacher will assess the degree of understanding of the subject by the completeness of the responses and the ability of the student to establish connections between the various topics giving a score commensurate with the expressed understanding and capabilities that will be the score achieved for the overcoming of the module. The final score of the course will be the arithmetic mean of the scores of the two modules. There are no tests during the course but the teacher will continously asks questions to the students during the lessons to understand the extent to which the class itself is able to link content previously granted to those being delivered.
