"In Pursuit of Innovation, Interdisciplinary Collaboration, Internationalization & Inclusive Development"

Agricultural Engineering: Agricultural & Bio-Processing


Brief Description of the Specialization

The field of Agricultural & Bio-Processing (ABPRO) covers the gamut of handling and storage of crops in fresh form from farm to market, to processing of agricultural materials into food, feed products, and industrial products. Loss reduction, quality retention, improved efficiency, and cost effectiveness of the various postharvest and processing operations are prime considerations in development of technologies for ABPRO. Coursework covers heat, mass, and momentum transfer, crop processing operations, physical properties of agricultural materials, and refrigeration systems. Students are also encouraged to enroll in elective courses in other colleges of UPLB to broaden their perspective and increase their understanding of biosystems. These electives generally include courses in animal science, postharvest horticulture, agricultural economics, and food science.


Postharvest Engineering – high-value commercial crops include fresh fruits, vegetables, and cutflowers. Due to their inherent perishability, a significant fraction of the volume produced yearly is lost due to improper handling, inappropriate packaging, and inadequate storage and transport facilities. More distant production areas, greater need for food safety, and stricter quality requirements all pose an increasing challenge to agricultural and biosystems engineers. This area of specialization of Agricultural Engineering is involved in the sorting and grading, packaging, temperature management, transport, and short-term storage of high-value crops. Development of equipment, facilities, and protocols to reduce losses, extend shelf life, and maintain quality of perishable crops in fresh form are the main objectives of this field of specialization.
Crop Processing – involves the transformation of raw agricultural materials into intermediate or finished products such as animal feed, crude oil extracts for biofuel production, industrial fibers. This field of specialization involves the determination of physical properties of raw materials, development of size reduction and extraction equipment and processes, evaluation of processed products, and drying and dehydration methods. Special emphasis is placed on drying and milling of Philippine crops such as rice and corn.
Food Engineering – is the integration of the fields of engineering, chemistry, and microbiology for developing solutions to processing of food materials into finished products with added value and a stable shelf life. This field of specialization involves the development of new food products, pharmaceuticals, food processing machinery, packaging materials and edible coatings, processing protocols, and treatments for processing plant waste.
Energy Engineering – involved in biomass and other alternative energy resource development (calculation of energy potentials, policy formulation, status of the industry), biofuels potential and sustainability, energy conservation and efficiency measures, and theory and design of combustion systems for agricultural commodities.
Thermal Processing – principles and application of psychrometry in postharvest engineering and crop processing applications, design of refrigerated storage systems, and thermodynamic analysis of postharvest and thermal systems.


Prospective Students

Enrollees of the program may come from among the graduates of food science and technology, agricultural engineering, and chemical engineering programs of UPLB, as well as other universities offering undergraduate programs in these fields.



This field of specialization gives students perspectives on both engineering and biological aspects of a problem in handling and processing a crop into a higher-value product. This allows them to develop solutions that are innovative, appropriate, and sustainable. Hence, they are well prepared for careers in postharvest handling and storage of durable and perishable crops, food engineering, animal feed production, or the biofuel industry. Note that all these areas are expanding nationally as well as globally as food safety and security, and scarcity of oil become issues of concern.
