LABORATORY OF FOOD TECHNOLOGIES AND FORMULATIONS
Academic Year 2024/2025 - Teacher: ELENA ARENAExpected Learning Outcomes
1) knowledge and understanding: Interactions between ingredients in food formulations. Water, salts, proteins, fats. Cookie production technology process parameters. Role and characteristics of the ingredients. Short dough and hard dough, characteristics and properties. Effect of ingredient substitution on the properties of the finished product. The leavened. Yeast Preparation: Definition DY, French System and American System. Strength, acidity evaluation. Bakery. Methods of baking (direct, indirect, with carryover). Pastification. Processes and quality of the finished product. Beverage industry: preparation of basic syrups (° Brix, sugar substitution, viscosity). Knowledge of food labeling law.
2) ability to apply knowledge and understanding: the course, through the application of case studies in the laboratory, aims to provide the tools for transferring the knowledge acquired in the various disciplines to food production. In particular, the student, through the modification of each single ingredient, understanding the role and interactions with other ingredients will be able to evaluate the changes in the properties and quality of the finished products and choose the optimal systems to use. Ability to develop a label.
3) autonomy of judgment: the course makes the student capable of analysis and critical evaluations concerning the choice of the appropriate ingredients for obtaining the intermediate or finished product having the desired qualitative properties.
4) communication skills: ability to support and communicate choices regarding the subjects within their competence
5) learning ability: at the end of the course the student is expected to have the ability to apply knowledge skills in different contexts, orienting study methods and reasoning towards a work perspective
Course Structure
The course includes both lectures (or at a distance) and laboratory tests.
Information for students with disabilities and/or DSA.
As a guarantee of equal opportunities and in compliance with current laws, interested students can ask for a personal interview in order to plan any compensatory and/or dispensatory measures, based on their specific needs and on teaching objectives of the discipline. It is also possible to ask the departmental contacts of CInAP (Center for Active and Participatory Integration - Services for Disabilities and/or DSAs), in the persons of professors Anna De Angelis and Daniela Verdi.

Learning Assessment
Learning Assessment Procedures
Verification of learning takes place through oral
interview and discussion of laboratory experiences. The evaluation of the
student's preparation will take place on the basis of the following criteria:
learning ability and level of depth of the topics covered, properties of
synthesis and exposition, and the student's ability to reason.
The vote follows the following scheme:
Unsuitable
Knowledge and understanding of the topic: Important
shortcomings. Significant inaccuracies
Ability to analyze and synthesize: Irrelevant.
Frequent generalizations. Inability to synthesize
Use of references: Completely inappropriate
18-20
Knowledge and understanding of the topic: At the
threshold level. Obvious imperfections
Ability to analyze and synthesize: Just enough skills
Use of references: As appropriate
21-23
Knowledge and understanding of the topic: Routine
knowledge Analysis and synthesis skills: It is capable of correct analysis and
synthesis. Argue logically and consistently
Use of references: Use standard references
24-26
