MARTHA STEWART - Whether you are baking, cooking, or mixing up a cocktail, knowing how to juice a lemon properly can make a big difference. The humble yellow fruit might not seem complicated, but factors like temperature, storage, variety, and even the way you cut it can all impact how much juice you get.

We're sharing how to pick, prep, and juice lemons for maximum yield—plus which tools work best, and which tricks are worth skipping. We spoke with two experts, one has decades of research into lemon varieties and cellular structure, and the other teaches students how to handle citrus in a professional kitchen. Their advice will help you learn how to get the most juice out of every lemon.

Start With a Good Lemon
Juicing starts with selection. According to Tracy Kahn, Ph.D, curator of the Citrus Variety Collection at the University of California, Riverside, the fresher the lemon, the juicier it is likely to be. “If it’s been sitting in cold storage or traveled a long way, it may have lost some moisture through the peel,” she says.

UCR Citrus Gifts expands online with citrus and honey-infused marmalades, soaps, and more

UCR Citrus Gifts expands online with citrus and honey-infused marmalades, soaps, and more ilseu Mon, 08/10/2020 - 15:44 More College News Imran Ghori | UCR News August 10, 2020

The fruits of UC Riverside’s research are even easier to enjoy with the Citrus Gifts collection expanding its line of products and making them available online.

The collection, featuring marmalades and olive oils from citrus and bee research, have been sold in campus stores for about six years. In June, the campus began selling them online to expand their availability to the wider campus community and alumni.

“This idea of creating this very unique UCR gift item is a way to take a piece of UCR home with you,” said Leslie Gerretse, senior manager for Hospitality Services.

The decision to make them available online reflected their popularity with customers, particularly as graduation gifts, she said. With the campus and its stores closed due to COVID-19, the department wanted to quickly make gifts available to students in a convenient way, Gerretse said.

Online sales have been strong since the website launch, she said.

The line, which began with citrus products, has expanded to include honey from beehives managed by the Entomology Department’s Center for Integrative Bee Research, or CIBER. Body care products made from honey and/or citrus such as soaps and a honey lip balm were added last year. Other products include a honey-infused balsamic vinaigrette and a citrus-flavored chocolate bar.

Despite UCR’s long history of citrus research – dating to its incarnation as the Citrus Experiment Station beginning in 1907 – it wasn’t until recently that the campus began commercializing its citrus.

Dining Services has collaborated with the Givaudan Citrus Variety Collection at UCR and local vendors to produce items that take advantage of the diversity of citrus cultivated on campus. The Citrus Variety Collection includes over 1,000 types of citrus and related species of trees collected from all over the world or developed on campus, said Tracy Kahn, the collection’s citrus curator.

“There isn’t another campus or collection in the United States that has this level of citrus diversity,” she said.

Kahn, Gerretse, and Robert Getman, general manager of the Scotty’s stores, are the main group brainstorming ideas for products. They work with independent, local vendors to produce the items, keeping on top of the diversity of citrus varieties available and which of them are in season.

The partners include Redlands-based olive oil maker Lot22; E. Waldo Ward & Sons, a preserves firm in the San Gabriel Valley city of Sierra Madre; health and beauty vendor Principle Body Care in Redlands; and Parliament Chocolate in Redlands.

Kahn said they look for unique ideas that take advantage of the wide variety of citrus in the Citrus Variety Collection.

For instance, the Tango mandarin marmalade is made of a citrus variety that was a product of the UCR Citrus Breeding Program headed by Mikeal Roose, a professor of genetics in the Department of Botany and Plant Sciences. Tango mandarin is also produced commercially in California and around the world. In California, Tango is commonly included in Cutie and Halo trademarked boxes.

The blood orange marmalade combines four different cultivars. A recent addition is the sweet pickled Indio mandarinquat, a tangy condiment that has been used as a barbecue sauce at the Barn restaurant on campus.

“There’s a passion associated with putting these together,” Kahn said.

A portion of the sales proceeds go to the Citrus Variety Collection and CIBER.

“It promotes UCR, it provides this very unique product to have and share and it supports the efforts of the Citrus Variety Collection and CIBER through our sales of those products,” Gerretse said.

Citrus Gifts are available for ordering online at citrusgifts.ucr.edu.

LOS ANGELES TIMES - It has been described as a Noah’s Ark for citrus: two of every kind.

Spread over 22 acres, UC Riverside’s 113-year-old Givaudan Citrus Variety Collection was founded as a place to gather and study as many citrus specimens as possible — right now, the inventory numbers at over 1,000. It’s an open-air temple where innovations in irrigation, fertilization, pest control, breeding and more have allowed California’s iconic $7-billion citrus industry to thrive for over a century.

Givaudan brings its Virtual Taste Trek to Riverside

Givaudan brings its Virtual Taste Trek to Riverside ilseu Wed, 02/12/2020 - 13:03 More College News Holly Ober | Inside UCR February 11, 2020

Imagine enjoying the sights and scents of a springtime stroll across the UC Riverside campus and through the Givaudan Citrus Variety Collection, except you’re sitting at a desk. Wearing virtual reality goggles. And inhaling artificial aromas carefully constructed to replicate the real thing.

Givaudan, the flavor and scent company that donated $3.5 million to protect UC Riverside’s precious citrus collection from the citrus disease huanglongbing, brought a cutting-edge sensory tool to Riverside last week. It consists of virtual reality googles attached to a computer and a chest containing tubes of scent chemicals. As the user watches Givaudan Citrus Variety Collection director Tracy Kahn take a Givaudan representative through the groves, scent drifts from a small vent near their nose whenever a fruit is cut open.

“It smells great and you can tell whenever you’re smelling something different,” Kahn said. “You can smell the campus in the introduction and can tell they filmed it in the spring.”

Givaudan brings clients who want them to develop new citrus scents and flavors to UCR’s citrus collection. For clients who can’t come to Riverside, the “Virtual Taste Trek” recreates the experience of walking through the collection to discover the scents and tastes they’ll commission the company to create. Faculty and administrators from UC Riverside’s College of Natural and Agricultural Sciences got to take the Virtual Taste Trek at last week’s event.

To develop the experience, Givaudan researchers took a variety of fruit samples in UCR’s collection and analyzed the specific compounds that give each its distinctive scent. The same esters, aldehydes, and other molecules scent and flavor all types of citrus, as well as Givaudan’s flavors and scents.

The Virtual Taste Trek contains 13 of the 1,000 citrus varieties found at UC Riverside, though that’s enough to discover a wide range of scent. The dominant and underlying notes for each type of fruit appear on the virtual reality display. Users can dial various components up or down, adding more cinnamon notes, for example, or toning down the fresh notes. The corresponding mixture is pumped from the tubes, allowing the user to create and test new scents on the spot.
