“California-Native Elderflowers: How the Volatile Profile Changes with Post-Harvest Processing”
Katie Uhl, University of California, Davis
and
“Comparative Analysis of a Variety of Chili Peppers including Synthesized Compounds and Sensory Evaluation”
Neil C. Da Costa, International Flavors & Fragrances, Inc.
Abstract, California-Native Elderflowers:
While elderflower products are commonly seen on grocery store shelves, the subspecies native to the western United States, Sambucus nigra ssp. cerulea, has not been studied before. This study evaluated fresh and dry flowers from elder shrubs growing in northern California, as well as teas made with fresh and dry flowers for their volatile profile as well as teas made with fresh and dry flowers for their volatile profile via headspace solid-phase microextraction (HS-SPME) gas chromatography mass spectrometry (GC/MS). When comparing the flowers of this subspecies of elder, there were some key differences between the flowers, including the presence of methyl eugenol in the California elderflowers. This compound has not been identified in studies on European (S. nigra ssp. nigra). In addition, the volatile profiles of the teas made with fresh and dry flowers were significantly different from the plain flowers, driven by the presence of short chain aldehydes. This is the first study to compare these four elderflower preparations, and the results highlight the potential of this subspecies of elderflower to be used to develop novel elderflower products that have unique organoleptic properties compared to other elderflower subspecies.
Biography: Katie Uhl is a PhD Candidate in Food Science at University of California, Davis under Dr. Alyson Mitchell. She also holds a bachelor’s in food science from The Ohio State University. Her research at UC Davis has been a part of a California Department of Food and Agriculture collaboration to understand the composition of the subspecies of elderberry native to the western United States, Sambucus nigra ssp. cerulea in order to increase the use of the berries and flowers in value-added foods. Through this project, she has gained a wide variety of analytical skills to study food components, and she hopes to use these skills as a food scientist.
Abstract, Comparative Analysis of Chili Peppers:
Chili peppers are increasingly in demand in modern culinary preparations for use in a variety of international dishes. In-depth volatiles analysis was conducted on several highly pungent chili peppers included habanero (capsicum chinense), green serrano and red chili (capsicum annuum), cumari (capsicum praetermissum) and red and green malagueta (capsicum frutescens) varieties. The main pungency imparting capsaicinoids have been reported. In addition, key to these volatile compositions are esters including the 4-methylpentyl analogues, ionones, macrocyclics, amides and trace sulfur molecules. Comparison of the compositional ratios of components plus synthesized molecules and their sensory evaluations, will be presented.

An Evening of Hops and Beer Chemistry
“Creating Flavor for an Ever-Evolving Craft Beer Industry: Breeding and Production of New Hop Varieties”
Marshall Ligare, John I Haas, Inc.
and
“How the Mighty Hop Brings Flavor To Your Favorite Brew”
Kelly Carroll Jr and Dana Daneker Gasiorowski, International Flavors & Fragrances, Inc.
Abstracts:
Creating Flavor for an Ever-Evolving Craft Beer Industry - The known historical record of beer production dates back over 2,500 years. Although the use of hops in brewing seems ubiquitous to most beer consumers today, the modern IPA is a very new style in the history of beer. This shift in craft beer styles was driven by consumer preference and the availability of new hop varieties to create citrusy and fruity flavors. This presentation will cover the production of modern flavor / aroma hops from seed to beer, including modern industrial practices for breeding, growing, processing and chemical analysis.
The Mighty Hop - Many of us grab our favorite craft brew anticipating the reward of amazing aroma, great flavor, unique taste, and refreshment, few of us truly understand the drivers of these unique aromas and tastes. The art of brewing is constantly evolving to include interesting new varietals of Hops (Humulus lupulus) which drive significant and unique flavor profiles. Hops contain a complex blend of essential oil, terpenes, alpha and beta acids, flavonoids, lipids, polyphenols, minerals, protein, and cellulose, the building blocks taking the mighty Hop from a lovely Cone to a rainbow of flavor. These reactions are complex, involving thermal and enzymatic degradation with many flavor compounds being created through further isomerization, oxidation, esterification, and hydrolysis. We will be discussing some of our favorite and most flavorful hops derived molecules. Whether you prefer your brew to be bitter with high citrus character or more mellow and fruity, you will gain a deeper appreciation for the power of this beautiful natural product.

Council Actions
Committee on Committees Actions
▪ The Council approved the Petition to Amend the Duties of the Committee on Chemists with Disabilities (CWD.)
• This petition sought to change the language in the duties of CWD from students to persons to be more inclusive to ACS members of all levels and backgrounds participating in the Society’s meetings and events.
▪ The Council approved the continuation of the Committee on Chemists with Disabilities.
• The Committee on Committee reviews each Society Committee no less often than every five years and advises the Board of Directors and Council whether they should be continued. ConC completed the performance review for the Committee on Chemists with Disabilities and recommended its continuation.
Committee on Budget & Finance Petition
▪ The Council approved the Petition to Amend the Use of Dues.
• The petition has two major components. The first changes the basis for developing the total pool of allotments available for local sections and technical divisions. The second eliminates the connection between dues revenue and C&EN.
• The total resource pool available for distribution to Local Sections and Divisions will be funded via a quasi-endowment established from the Society’s unrestricted investment balances. This replaces the previous pool that was funded through the allocation of 20% of dues revenue to local sections and divisions.
Committee on Divisional Activities Action
▪ The Council approved a division name change.
• Effective January 1, 2023, the Division of Carbohydrate Chemistry (CARB) will change its name to the Division of Carbohydrate Chemistry & Chemical Glycobiology (CARB).
Committee on International Activities Petition
▪ The Council approved a Petition to Charter an International Chemical Sciences Chapter.
• This petition, contingent on approval by the ACS Board of Directors, allows for a new International Chemical Sciences Chapter in Switzerland.
Committee on Membership Affairs
▪ The Council approved the extension of market testing of the international dues discount program based on World Bank country income levels.
• The test provides reduced dues for international members residing in emerging nations, which host an ACS chapter, and as defined by World Bank income criteria.
• The test results to date have suggested a positive impact on membership through new members and the expanded inclusivity that a wider global community provides.
▪ The Council approved the 2023 Schedule of Membership.
• The 2022 Schedule went live a few short months ago, and the 2023 Schedule was designed to add more value and increased choice for membership by adding clarity and a more intuitive explanation of how our membership works.
• The 2023 Schedule of Membership did not change any dues, benefits, eligibility, or privileges from the 2022 Schedule.
Resolutions
▪ The Council passed several resolutions:
- in memory of Past President Nancy B. Jackson;
- in memory of deceased Councilors;
- to officers and members of the San Diego Local Section.
Highlights from Committee Reports
Budget and Finance
In 2021, ACS generated a net from operations of nearly $79 million, which was almost $48 million higher than budgeted. Total revenues were $660 million, which was 5.2% or $32.6 million over budget. Expenses for the year were $581 million, or 2.5% below budget. This overall result was attributed to strong revenue performance from the Society’s Information Services units (CAS and ACS Publications), reduced spending due to COVID-19 related impacts, and careful management of expenses across the ACS.
The Society’s overall financial position strengthened considerably in 2021 as Unrestricted Net Assets, or reserves, increased by $123 million to $676 million on December 31. The increase was primarily the result of the $79 million net from operations and growth of the Society’s investments totaling $71 million.
Nominations and Elections
The Committee on Nominations and Elections solicits Councilors’ input regarding qualified individuals for President-Elect and/or Directors for future consideration. Suggestions may be sent to nomelect@acs.org.
Committee on Committees
All Councilors, including new Councilors, were reminded to complete their online committee preference form for 2023 committee assignments. The preference form will be open to all ACS members and no one will be required to request permission to gain access to the form. The new form will allow users to review each committee by its main topic and focus, along with the skills and expertise needed to serve.
The committee preference form will open mid-April at CMTE.acs.org. Users will also be able to submit a skills assessment which will be used when considering which committees may best suit their talent.
ACTIONS OF THE BOARD OF DIRECTORS - EXECUTIVE SESSION
The ACS Board of Directors met in Executive Session on March 18 and March 19, 2022 at the ACS spring meeting in San Diego. They considered several key strategic issues and responded with numerous actions. The Board opened its session with a reflection on Diversity, Equity, Inclusion and Respect (DEIR), led by Immediate Past President, H. N. Cheng.
The Chief Executive Officer’s Report
The Board received an extensive report from the CEO on issues relating to ACS core values of safety and DEIR, membership, financials, the ACS Institute, strategic initiatives, and upcoming events and activities. Notably, the strategic initiatives include funding of up to $50 million over 5 years for sustainability, fostering a skilled technical workforce, accelerating digital research data projects, and accelerating life sciences growth.
The Board’s Committees and Task Forces
The Board received and discussed reports from its committees on Executive Compensation, on Professional and Member Relations, as well as the ACS Governing Board for Publishing, Budget and Finance and the Working Group on Structure/Representation. Some of these committees requested and obtained Board action on one or more items, as follows.
▪ The Board received an extensive briefing and approved several recommendations from its Committee on Executive Compensation. The compensation of the Society’s executive staff continues to be reviewed regularly by the Board.
▪ Upon recommendation of the ACS Governing Board for Publishing, the Board voted to approve the reappointment of one of its members. The reappointment will be announced once the individual has been notified and appropriate arrangements for their continued service have been made.
▪ Upon recommendation of the Committee on Professional and Member Relations, the Board approved five nominees each for the 2023 Priestley Medal, the 2023 Award for Volunteer Service to the ACS, and the 2023 Charles Parsons Award as well as a recommendation for an ACS nominee for the 2022 GRAND PRIX of the Fondation de la Maison de la Chimie.
▪ Pending the approval by Council of the Petition to Amend the Use of Dues, the Board of Directors resolved to authorize the creation of a quasi-endowment from proceeds in the ACS General Fund. This would have an initial principal amount of $85 million, the annual payout from which would fund individual technical divisions and local sections per the allotment policies established by the Committees on Divisional Activities (DAC) and Local Section Activities (LSAC). Further, the amount of funding available made available for this purpose would be the standard payout from this quasi-endowment or $3.2 million, whichever is greater.
Other Society Business
By consent, the Board ratified interim actions on moving the June 2022 Board meeting to Sunday, May 22- 23 in Atlanta, GA (so as to be co-located with the leadership institute); and approved the recommendation of the Office of Research Grants (with assistance from the Frasch Committee) for the 2022 Herman Frasch Foundation Grant in Agriculture Chemistry.
As is customary, the Board heard reports from the Presidential Succession on their current and planned activities for 2022 and 2023.
Also, the Board adopted the resolution in memory of ACS Past President Nancy B. Jackson, who passed away in January.
