Cereal Products: Traditional and Innovative Technologies
A.Y. 2019/2020
Learning objectives
The course aims to provide students with the knowledge related to the characterization of cereals and their transformation into semi-finished and finished products using conventional and innovative technologies. The main objective of the course is to provide students with the knowledge on the modifications of the main macromolecules present in cereals during the technological process and their role in the physical, structural and sensory properties of the food.
Expected learning outcomes
At the end of the course the students will be able to define the commercial quality classes of cereals and flours. Students will be able to interpret technical specifications relating to the marketing of cereals and flours. At the end of the course the students will also be able to apply the appropriate technology in the different phases of a production process that uses cereals and flour to reach the highest quality level.

Course syllabus
RAW MATERIALS: CEREALS The international and national cereal sector: structure, market and the major issues. Morphological, physical and chemical properties of the kernel of major cereal crops. The pseudocereals in comparison with cereals. Quality indices and their evaluation. Criteria of (technological, commercial, etc..) classification for wheat and other cereals in Italy and worldwide. The major macromolecules in the grains: chemical, physical and structural features. The phenomenon of germination: control and prevention.
PRODUCTION OF SEMI-FINISHED PRODUCTS The milling sector in Italy. Process description of wheat milling: differences in milling diagrams between common and durum wheat. The milling of other cereals (corn, etc..). Assessment of rheological properties of flours. Innovation of first processing processes (hulling, parboiling, etc..). By-products utilization and enhancement: recovery of interesting components for secondary processing and / or for energy purposes industries. FINISHED-PRODUCTS PRODUCTION Pasta. The pasta-making process for dry pasta: macroscopic and molecular phenomena related to pasta-making. Technological innovations. The production of fresh pasta: main differences with the technological process for dried pasta. Cooking pasta: phenomena and their intensity, evaluation of cooked pasta quality. Production of enriched pasta.
Bread and other leavened products: Classification. Dough characteristics: the role of water, flour macromolecular components and other ingredients, improvers and enzymes; mode of/types of kneading. The proofing and the formation of a crumb structure. Cooking: stabilization of the structure. The phenomena related to bread aging (staling), their evaluation and slowing. Product (low glycemic index breads, fiber-enriched breads, etc.) and processing (continuous processes, with use of pre-ferment, frozen bread production, etc..) innovation.
Processing of gluten-free cereals (maize, rice, sorghum) and pseudocereals in products such as bread and pasta.
