Reducing harvested food waste
Currently working at the University of Newcastle as a lecturer and researcher, Dr Penta Pristijono chose to work in food science because of its universal relevance.
“Food is essential for the human body, regardless of demographic, age, gender or health status,” he said.
Penta began his own study journey with a Bachelor in Fisheries Science in Indonesia.
“My passion has always been food, especially food science.
“I enjoy good quality food, but some of my favourite foods, like seafood, are perishable.
“So, I decided to take on a bachelor’s degree in fisheries science to explore more about factors affecting food spoilage,” he said.
Penta then went on to undertake postgraduate studies in Australia, completing a Master of Food Technology and PhD in Food Science at the University of Newcastle. This is where he developed his interest in horticulture postharvest research.
Penta’s then completed post-doctoral research in horticulture postharvest at the University of Newcastle, which was funded by the ARC Industrial Transformation Training Centre for Food and Beverage Supply Chain Optimisation.
As a current lecturer in Food Science and Human Nutrition, at the Central Coast campus, Penta teaches students about food science and food quality management and is very proud of the program.
"There are a large number of food companies in the region, so our students will have opportunities to gain experience from local industries.
“Our program covers laboratory practical experiences on wide range of different topics which prepare graduates to enter the workplace in varied food industries.
“Our program also covers human nutrition topics, which prepares graduates to also enter nutrition professions,” Penta said.
Apart from lecturing, Penta continues to research in the area of horticulture postharvest.
“Initially, my horticulture postharvest research involved preventing the browning process of fresh-cut surface of apples and lettuces using nitric oxide gas and its donors’ compounds.
“I am now working on developing innovative postharvest technologies to extend the storage life of fruits and vegetables.
“This involves delaying the ripening and senescence process, as well as controlling postharvest pathogens,” he said.
Penta has now extended his research interest to developing alternative combinations of treatments with different packaging materials to prolong horticulture postharvest lifespans of stored fruits and vegetables further.
Penta’s passion came from his awareness of the levels of food waste, especially in the horticulture sector after harvest includes during transportation, processing, and storage.
“Fresh fruits and vegetables are living tissues which have a short shelf-life after harvest, and improper preservation results in an even shorter shelf-life.
“This directly affects farmers and consumers and is a new challenge to discover how we can produce more innovative ways to reduce waste,” Penta said.
Penta believes Food Science is an extremely important industry.
“As food scientists, we will always be facing new challenges of providing high quality food that meets consumer demands.
“I believe the food sector has huge opportunities for future careers as we attempt to solve these challenges.
“We are a highly dynamic sector and are constantly developing,” he said.
To future students considering studying a Bachelor of Food Science and Human Nutrition, Penta says to follow your passion.
“If you have passion about food, our Food Science and Human Nutrition programs provides practical training in a wide range of food topics with a very current and innovative approach.
“We also combine the nutrition aspects into the program which provide stronger impact on graduates’ readiness to enter the job market,” Penta said.

Career Summary
Biography
Profile
Dr Penta Pristijono awarded a Masters of Food technology and a PhD in food science from the University of Newcastle Australia, under supervision of Prof Ron Wills. This was followed by an ARC Industrial Transformation Training Centre for Food and Beverage Supply Chain Optimisation funded Post-Doctoral researcher at The University of Newcastle, investigating innovative non-chemical horticultural postharvest treatments to extend fruits and vegetables postharvest life. He is currently a Lecturer in Food Science.
Research
Research expertise is focused on Horticultural postharvest technology. His PhD research investigated the effect of Nitric Oxide (NO) to extend the postharvest life of fresh-cut and intact fruits and vegetables. During this research, he was the first to measure effectiveness of NO to prevent enzymatic browning in sliced Granny Smith apples and Iceberg lettuces. Key findings include consistent action of NO to delay the browning of fresh cut apple and lettuce, and NO inhibited mould growth on number of produce, and there was no consistent effect of NO to prevent ripening of climacteric produce. During his Post-doc, Dr Penta Pristijono investigated the effect of physical, gas and heat treatments for extending horticulture postharvest life. The innovative treatments include UV-C irradiation, ethylene (C2H4) gas, low pressure storage, hot water shower, 1- Methylcyclopropene (1-MCP) and edible coating, to delay senescence without refrigeration. Majors’ effects found includes significant degreening prevention of fresh produce by UV-C irradiation and mold reduction due to low pressure storage, leading to delaying fruit ripening and preventing fruits senescence during storage. Effects were especially apparent in tomatoes and limes treated with UV-C irradiation, and zucchinis and tomatoes stored at low pressure atmosphere.
Recent research has been extended to the use of other current innovative postharvest treatments include essential oils, amino acids, hydrogen sulphide (H2S) gas and auxins to extent postharvest life of green vegetables and citrus fruit. His research interest also to develop alternative combination treatments of current postharvest technologies with different packaging materials to further prolong postharvest life of fruits and vegetables. He has established successful collaborative research with Dr John Golding (NSW DPI) to extend the postharvest life of horticultural produces using current innovative postharvest technology that delay ripening, senescence process and control postharvest pathogens.

Florets were dipped in aqueous solutions of the amino acids at concentrations from 1.0 to 100 mM and stored at 10 °C. A 5 mM dip was found to be optimal in delaying senescence as measured by retention of green colour, vitamin C and antioxidant activity, and a lower level of ethylene production, respiration, weight loss, phenylalanine ammonia lyase (PAL) activity and ion leakage with the benefits being similar for all three amino acids. Arginine, cysteine and methionine have Generally Recognised As Safe (GRAS) status and should have few impediments in obtaining regulatory approval for commercial use if similar effects were found for other leafy vegetables.

The results revealed that solvents significantly affected the recovery of ES, TPC, TFC, and antioxidant properties. Absolute methanol and 50% acetone resulted in the highest extraction yields of TPC, whereas absolute methanol resulted in the highest extraction of TFC, and water had the highest recovery of vitamin C. 50% ethanol, and 50% acetone had higher extraction yields for TPC, and TFC, as well as higher antioxidant activity compared with their absolute solvents and water. TPC and TFC were shown to be the major components contributing to the antioxidant activity of lemon pomace.
