Reduce, Reuse, Recycle: A Sustainable Packaging Approach

Thursday, June 6th, 2013

Session 183
July 15; 1:30–3 p.m.
Room S404abc

This session begins by offering a brief overview of antimicrobial packaging with emphasis on sustainable packaging materials for meat and poultry products, as well as regulatory considerations. Next, the session speakers will delve into active packaging features, which work together with intrinsic food shelf life factors to extend the length of time that packaged foods are safe and acceptable. Many of those features are often as “natural” in origin as the packaged food, and have long partnered with product and package for shelf life extension without “artificial chemicals” objections. Growth of such applications has languished in spite of significant, untapped potential. The speakers will share a study that assesses drivers for new applications in the context of current market priorities and suggests how active packaging features can deliver fresher consumer choices in place of highly processed ones.

The last speaker will discuss the topic of sustainable packaging by highlighting a case study in Africa. The most economically-important, indigenous African grain legume is cowpea. The people of West and Central Africa, among the poorest and least-educated in the world, grow cowpeas for family food and to sell for needed cash. Unfortunately, trade in cowpeas is severely hampered by storage insects, especially the cowpea weevil. Unprotected cowpeas can be totally destroyed by the cowpea weevil after only two or three months. Faced with seemingly inevitable losses, cowpeas are often sold at harvest, when the price is lowest. Storage insecticides can be used to control cowpea weevils, but poor farmers often do not have access to these insecticides, and when they do, they often misuse them, resulting in health and environmental problems. In the case study, a non-chemical method for cowpea hermetic storage using a triple-layer plastic bag (called the PICS project) was introduced.

Packaging for Novel Processing Technologies

Wednesday, June 27th, 2012

To meet consumer demand for safe, more fresh-like foods with increased product shelf life, several nonthermal (e.g., high pressure, pulsed electric field) and advanced thermal (e.g., microwaves, Ohmic heating) have been developed as alternative technological solutions for food preservation. The use of these technologies has opened up exploration of unique materials and novel packaging technologies to withstand the processing conditions and ensure the safe shelf life of the foods. In addressing a similar need for extending safe product shelf life with commodities such as berries, novel antimicrobial packaging systems are being developed that can eliminate mold and adventitious pathogens simultaneously.

Session 240 Case Studies in Packaging for Novel Processing Technologies, which takes place on Thursday morning from 10:30 a.m. to 12:00 p.m. in Room N111, provides case studies for the commercialization of innovative laboratory discoveries across a spectrum of packaging systems and cross-cutting applications in processing technologies by high pressure processing, microwaves, and chlorine dioxide for fresh produce. Presentations will provide insightful scientific analysis of packaging barrier properties of innovative packaging materials in response to high pressure processing and microwave sterilization and their crucial role in preserving the quality and safety of foods over product shelf-life. An innovative antimicrobial packaging system currently based on a novel chlorine dioxide-producing chemical system invented by the Army and recently licensed to commercial industry will be highlighted.

Antimicrobial Packaging with Biopolymers May Solve Food Safety Issues

Tuesday, June 26th, 2012

Recently, recalls and outbreaks of cantaloupe, tomato, shell egg, and ground meat due to foodborne pathogen contamination have highlighted the need for effective decontamination methods to ensure the safety of foods. Foodborne illness poses a $77+ billion economic burden in the United States annually. As an additional hurdle to non-thermal processes, antimicrobial packaging can play an important role in reducing the risk of pathogen contamination, as well as in extending the shelf life of minimally processed foods. Currently, food applications of antimicrobial packaging systems are limited due to the availability of suitable antimicrobials, new polymer materials, regulatory concerns, and appropriate testing methods. Thanks to concerns about the environment and sustainability, it is critical to design packaging products that utilize renewable resources while providing consumers a better package for protecting and dispensing the foods they buy.

Session 096 Development of Antimicrobial Packaging with Biopolymers to Solve Food Safety Issues will take place on Wednesday morning from 8:30 a.m. to 10:00 a.m. in Room N115. The symposium will focus on the development and application of biopolymers in antimicrobial packaging that can be used for reducing or inhibiting foodborne pathogens. The speakers will address current problems and challenges; discuss the different approaches to development of antimicrobial packaging systems with biopolymers; present the physical, mechanical, and antimicrobial properties of packaging materials; demonstrate their applications in various foods; and propose future research directions and collaborations in this research area.

Open Innovation Programs Drive New Food CPG

Monday, June 25th, 2012

Among the 11 Pre-Annual Meeting Short Courses held prior to the 2012 IFT Annual Meeting & Food Expo, a new course—Commercializing Innovation in Food Products (Monday, June 25)—offered attendees an inside look at commercializing innovation from ideation, sourcing, intellectual property considerations, valuation, and implementation to market launch.

The term “open innovation” is relatively new; in fact, it wasn’t officially coined until 2003 by Henry Chesbrough who got companies thinking about a new way of conducting the product development process. While Chesbrough firmly believed that companies have excellent internal resources—meaning the employees have a great deal of knowledge—he was also willing to admit that there are many smart people outside of company walls. Therefore, he believed it to be vital to seek out external experts to get insight on how to solve certain product development problems.

Since 2003, many large companies have implemented the open innovation process and have used it to successfully launch new cutting-edge products in the marketplace. For example, General Mills launched the General Mills Worldwide Innovation Network (G-WIN) in 2010 to actively seek partners that can help the company deliver breakthrough innovation in categories such as packaging, technologies, and ingredients.

As Alfred Malouf, NineSigma, explained in the opening presentation to the Short Course, there are many advantages to utilizing open innovation for product development. “People can have preconceived notions about how something should be done, but maybe there is someone out there who has a better idea that may be simpler, costs less, and is easier to develop,” said Malouf. In addition, this can help save time that would be lost “reinventing the wheel” and accelerate the innovation process.

However, in order to be successful, an open innovation program has to be integrated and sustained across the value chain. “It is vital to get all the stakeholders along the value chain involved in the beginning,” said Malouf. Another mistake some companies make is that they use the open innovation program solely for large projects. Malouf believes it should be used for smaller, incremental projects as well.

Ritz ChipsTo give the short course attendees an example of open innovation at work, Malouf offered a case study of how NineSigma helped Kraft solve a packaging problem. As an open innovation service provider, NineSigma works as an intermediary between a client and solution providers. In this case, Kraft’s consumer research showed that while consumers love Ritz Chips, they aren’t fans of the re-sealable bag. NineSigma sought out solution providers and came back with nine proposals. One was from Biomimetics, which uses nature to solve human problems. In this case, they looked at how nature would repeatedly open and seal items. Kraft ended up contracting with Biomimetics to develop a biology report on closures used in nature.

At that point, Kraft was still faced with the challenge of how to take these solutions found in nature and apply them to packaging. So they reached out to Michigan State Univ.’s Packaging and Engineering School and created a student competition to develop a solution to the Ritz Chip packaging problem using one of the methods described in the Biomimetics report. The winning team’s concept is currently patent pending and will be on store shelves soon.

Malouf ended his presentation by reminding attendees that open innovation—in fact, any kind of innovation—is hard work and requires persistence. As illustrated by the Kraft case study, it is often the nontraditional paths that lead to some of the most exciting new technologies and products.

The ABCs of BPA

Saturday, June 11th, 2011

Bisphenol A (BPA) is widely used by food processors in can linings and other packaging applications. Recent toxicological concerns have led to recommendations to discontinue many, if not all, of the current uses. Legislation at the state level has called for bans on BPA’s use in baby bottles and other food-related uses. This would require adopting replacement substances and/or procedures that have other risks. There is substantial controversy surrounding how to quantify the risks, particularly for extremely low doses resulting from package leaching. In addition, there are major differences in the alternatives that could lead to decreased product safety and shelf life.

On Sunday afternoon from 1:30–3:00 pm in Room 394, Session 070 BPA and Its Alternatives: Quantifying the Risks will discuss the impact of implementing such changes, including the likely risks of BPA at low exposures (e.g., in the range of doses likely to be encountered as a result of leaching from packaging). The symposium will also explore alternatives to BPA, an evaluation of potential low-dose risks for these compounds as well as differences in performance, and the impact on packaging and manufacturing.

Speakers include representatives from the U.S. FDA, a metal packaging association, and a consultancy specializing in chemical regulations.
