TECHNICAL COMMITTEE FOR JUICE AND JUICE PRODUCTS
SPRING MEETING
MARCH 31, 2000
PICCADILLY INN, FRESNO, CA
Ø Steve Kupina begins the meeting with introductions, then motions to approve the September meeting minutes.
Ø The membership report is discussed, everyone who has not paid are urged to pay dues. The treasurer’s report was not available. It will be sent out with the minutes of today’s meeting.
Ø Grants are discussed. Regarding the BMIS grant with Nick Low, PAI signed the funding for $12,000, TCJJP sponsored $5,000. It will begin May 2000 and will run for 2 years, final report in 6/2002. The Total Anthocyanins grant with Ron Wrolstad was discussed; the group had questions about the statistical design. It was noted that Ron must call the statistician and discuss the ruggedness stats with him. The group then questioned if this study is actually needed or not; the opportunity for it might have been missed. There is a European collaboration study currently in progress that Ron has been a part of. Steve Kupina will follow up with Ron.
Ron Wrolstad will provide a summary regarding the study.
q Nick Low had volunteered at the last meeting to get the grant form reviewed by an attorney. No information is available as yet, but Steve Kupina will contact Nick and get the information.
Ø There is discussion whether to use the money from TCJJP for collaborative studies
Ø Carla discusses questionnaires that were sent by the NIST to prioritize OJC, AJC, to the TCJJP members. It is proposed that the questionnaires will be sent to all members with the minutes. Each member is directed to complete the questionnaire and send to Karen Barnes at the address listed for her. The committees will then collect and analyze the results by June 1st.
Ø Eric moves to invite the NIST to the TCJJP meeting in Pennsylvania.
Ø There is discussion regarding Collaborative Studies and other research.
q European Commission Collaborative Studies-Ian took part, in regards to Anthocyanins and polymethoxyflavones,, both studies did well, the nitrate study was not successful, and did not go forward. Regarding. Carotenoids, the laboratories produced consistent chromatograms, but requires attention to detail. The research is finished and has been sent to the AOAC.
· Michelle Lee from Eurofins will get a copy of the report.
· Roy Lyon will find out if the document is on the EU website, and the logistics on posting it on the TCJJP website.
q Carbon 13 Ethanol Method-Roy Lyon will get information. The research is finished and is sent to AOAC.
q Metals, Sugars, and Vitamin C- David Hammond says that it has not been finished. There is a constant bias due to the levels are too close together. David Hammond and Eric Wilhemsen will look further at Metals and Sugars, and it is recommended that Eric also follow up on the Vitamin C.
q Cap GC HIS and HFCS-PVM done, it will be published in the AOAC-Mike McLaughlin says that there is a minimum of 15 labs, and they just received the data from the last lab.
q Cap GC Heat vs. Beet- The first paper has gone out, and was published in the Journal of Agriculture Food Chemistry. There is a problem with the second paper.
q HPLC –PAD- There is no work on this study for MIS, EV method did not work well. Ian Howard comments that the study is unreliable; an electrochemical detector is not the best for extending this method.
· Steve Kupina will clarify with Nick if he will continue or drop the study.
q Pulp Wash-Paul Cancalon comments that there is a problem because of microbiology, and further study is required. France is using the method currently, but the problem is that now that the in lines are connected, there is a question of how to check for ACB in evaporator condensate. Florin used as a marker will disappear if pulp wash is treated with resin. There is discussion regarding the water used in reconstitution of concentrate-portable vs. condensate. EV does not like simply potable water used in leaching, it will affect mineral composition; they believe condensate should be required for from-concentrate juices as the same as for single strength juice. Proposal for resolution-note for US Citrus to approach AIJN, for this as a topic for discussion. Committee decides to wait to see how it develops, and to support forums to voice their opinion. Committee understands that the TCJJP cannot change anything right now.
q Anthocyanins-Carla Barry will try to get something in writing in regards to approaching the AIJN to have this as a topic of discussion.
q Limonin-There will be a collaborative study this summer at 3 levels, 2 fruits (orange and Grapefruit). A request was sent out to all members that want to participate in the collaborative.
Participants may not enter into the collaborative study without a pre-trial check sample.
· Interested participants must either fax or email the proposal to Carla Barry; she will prepare the samples and send them out.
· Hans will send Carla protocols and information.
q Polyphenolics- There is approval from NFPA to take over, the chemist is ready, and the phosphate buffer will proceed. The committee will need to see some information in Pennsylvania. Tom Eisele voices concerns that Arbutin is still a problem; that it will not work for all types of fruit under the same operating conditions.
· There appears to be more compounds in white grapes, not sure what they are. Diode array detectors may not all be equal. Carla suggests that if we all use the same methods, we can compare the fingerprints.
q Capillary Electrophoresis-Little progress in developing a Peer Validated Method. Requirements have been reviewed, but it has not moved forward due to time constraints. The question is asked if there is still interest for this to be done, due to the expense of the CE for the laboratories. Conclusion-Yes, cost is coming down, new methodologies are coming available. The list of collaborators for this research includes Lynn Hageman, Karen Barnes, and Roy Lyon. Steve will prepare the samples and send out prior to the next TCJJP meeting in Philadelphia.
Ø European Fruit Juice Directive Update-Ian Howard comments that on the December 7th, 1999, under the Finish Presidency, a document, 8 years in the making, was produced in regards to the labeling of Product fruit juice and Product fruit juice from concentrate. This legislation, even though the European parliament could possibly block it in some way, will probably be ratified and will hit the statute books by September/October. Companies will then have 18 months to change packaging and then will not be able to sell fruit juice without the specified labeling. Suggested-PACS run foul of Quid legislation. If a company uses orange juice as an ingredient, this new legislation will begin to affect their ingredient list. The French and Spanish are pushing this legislature. They felt that the labeling wasn’t clear in the distinction between orange juice which was fresh and that created from concentrate. Enzymes mentioned were pectinase and amylase, not cellulase.
Ø IFU Cuba Report- Hans Hofsommer comments that it was successfully completed in February, a meeting consisting of 400 people, (100 Cubans). The book is coming out and the lectures available. The methods discussed included those for starch, nitrate fruit juices, relative density, ring test on cellobiose, vitamin C, SO2, color, turbidity, dilution water issue, limonin, gluconic acid (molds in grapes), glycerol, heavy metals, and the enzymatic method. Report coming out later this year.
q Hans will give an update about the meeting, use TCJJP to get the most update information to everyone, propose that TCJJP collect information,
Ø Alicyclobacillus in Apple Concentrate-There is a 1999-detailed report about Abecitrus in orange juice. It grows at 42-53C, and takes 24 hours to grow to a taint. It can be found in tomato, white grape, apple, orange, and pineapple. It cannot be seen, there is no gas, there is some sediment, and spores are heat resistant. The D-value is at 65 min., and started with poor taste, but the problem could not be detected. It is found that some people could taste dibromophenols at very low levels, some not at all. Only 16% of the samples will develop a taint problem. It has not been seen in apple until this September, and ultrafiltration will remove the organism. It also may grow around 40C, at 25C no growth in orange juice. It is present in glucose syrup. and seems to be a non-uniform distribution.
q David Hammond supplied the home page address for Abecitrus to download the research paper on thermophilic bacteria-www.abecitrus.com.br.
q Eric will talk to Linda Harris at US Davis about the potential correlation and ACB information.
Ø Steve makes a motion for the members of the TCJJP to be the nominating committee for the Don Petrus Award. After discussion within the board, it is decided that the Don Petrus Award will be renamed to the TCJJP Award, it will be a bi-annual award and nomination forms will be available on the website after the fall meeting in Philadelphia. The first award will be given to Don Petrus.
Ø Minutes from the CODEX meeting are handed out, and discussion regarding the CODEX Guidelines. The minutes are reviewed and changes noted.
Ø Database- There are no changes, although there is more data to be entered.
Ø The next TCJJP meeting date has been set to begin at 8:30am to 2:30pm on September 14th, 2000 at the Adams Mark Hotel in Philadelphia, PA. It is in conjunction with the AOAC Annual Meeting September 10-14, 2000. Codex is on September 18, 2000.
Ø Volunteers for a nominating committee for the upcoming members vote will be as follows: Steve Kupina, Carla Barry, and Elia Coppola. The terms that are up this year: Roy Lyon, David Hammond. Positions needed are one board member, secretary and treasurer.
Ø Motion passes to continue to use temporary agency to take minutes at upcoming meeting.
Ø It was decided that Steve Cockram will look into the Bylaws by the next meeting date to determine how to 1) change bylaws, 2) increase chairman’s term to 2 years, and to 3) find the guidelines regarding changing the committee’s name to include “International”. A proposal will be drafted to split the secretary /treasurer position.
q Dana Krueger will be asked to look into getting an electronic version of the Bylaws. Martin Stutsman to scan and OCR(Optical Character Recognition).
Ø There is a proposal to have a meeting in the UK. The group discussed potential dates and the interest of the members.
· David Hammond will put together a program for the next meeting for a proposed itinerary and flight information.
Ø There is discussion about a TCJJP logo being created. It is agreed that a logo will be appropriate, and the committee decides to provide a prize for the best idea submitted. (The prize is still to be determined.) Various submitted logos will be created as JPEG files and will be posted on the website to be voted on. (Website-TCJJP@TCJJP.ORG)
Ø A question is raised about membership and the growth rate the committee has seen in the past years. There is a motion to invite the NJPA to the TCJJP meetings, and the potential of having a meeting in conjunction with the NJPA in Spring 2002.
Ø Meeting adjourned.
