The Blessed Oil of Solitude
California State Mission

Nuestra Senora de la Soledad
by Teresa Giovanzana

In 1998, Gabrielle Leonhard of the Mission Olive Preservation, Restoration, and Education Project (MOPREP) visited Nuestra Senora de la Soledad in the Salinas Valley. Gabrielle recalls, “The wind was blowing, dirt filled the air, a door was slamming open and shut, a dog barked in the far distance; yet the silence and emptiness were immense.” Soledad is solitude in Spanish; Our Lady of Solitude Mission, a name appropriately chosen by the Franciscan padres who established the Mission in 1791. Salinas Valley is wide with mountain ranges on both sides and the Salinas River running through it. In the foothills, approximately ten miles away from the mission, are the Pairaso Springs, where ancient mission grape vines have been found. This is probably the original location of the olive orchard, although no ancient trees are left. Historians know olive oil was produced at Mission Nuestra Senora de la Soledad, for a piece of the original press has been excavated from the center courtyard.

Gabrielle found twelve older olive trees at the Mission, planted in the 1920s and 1960s during the Mission’s restoration but, at least in known memory, never harvested. Gabrielle suggested oil could be made from the Mission’s own trees, which could be used for the Sacraments. Nick Bianchi, the mission’s museum curator, immediately embraced the idea and began planning the first harvest. MOPREP volunteers, Tim Noonan and Gabrielle, headed up this project and enlisted olive tree consultant Antonio Isern, and Allesio Carli, wine maker and olive oil master, at Pietra Santa Winery near Hollister. The team began to teach the volunteers about harvesting, irrigation, pruning, and proper horticultural care. Allesio continues to press their olives annually.

In the winter of 2000, Mission Soledad volunteers pressed its first harvest from the twelve old trees. Not since Mission secularization in the 1830s, had any mission produced its own sacramental oil. This was a historical event. Bishop Sylvester Ryan of the Monterey Catholic Diocese was thrilled to be able to consecrate oil from Mission Soledad for Chrism oil, one of the three sacramental oils found in every Catholic church. That spring, on the first Monday of Holy Week, Mission Soledad’s olive oil was consecrated in a very old, traditional, and symbolic mass where all clergy annually renew their vows. Before the end of the mass, the oil was decanted and given to all the fifty-seven churches and parishes within the diocese. Three days later, on Holy Thursday, the three sacramental oil decanters were ceremoniously brought into their new home churches during the evening mass. For the next year, Mission Soledad’s oil was used for every baptism, wedding, last rites, ordination, and anointing in the diocese.

Since Mission Soledad’s first harvest in 2000, olive oil production has continually increased each year. 2005’s harvest, the largest yield to date, resulted in thirty-five gallons of extra virgin to the diocese for this year’s Chrism mass. “No other Mission, nor diocese, is producing their own olive oil for the Chrism. I am very proud of Mission Soledad’s accomplishment and contribution to our community,” said Bishop Ryan.

MOPREP and Mission Soledad began a very long and fruitful collaboration on that windy day back in 1998. Since then, in 2001, the mission volunteers and MOPREP planted 150 trees next to the mission. The orchard took two years to plan, propagate, establish seedlings, and then plant. MOPREP propagated Mission Soledad’s olive trees from hard wood cuttings called truncheons, an ancient propagation method used by the padres. The truncheons were from Mission La Purisima’s ancient olive grove. Mission Soledad’s new orchard was the first that had been planted since the founding of the missions. Mission La Purisima’s ancient grove was undiscovered until MOPREP found it in 1998. Nick Bianchi, Mission Soledad’s museum curator and olive grove manager commented, “It was so exciting! The trees were returned to the ground of their ancestors!” Mission Soledad will harvest the olives from their new orchard for the first time this winter.

MOPREP is a volunteer effort in collaboration with many of California’s olive oil producers, the California Mission staffs and volunteers, and the local communities, funded by private donations and MOPREP fundraising, to preserve California’s cultural link to the olive tree. Volunteers coordinate horticultural care, replanting, and olive harvests for oil making, at any of the twenty-one California Missions that request their assistance.

Olive Waste Component Adds Antioxidants to Bread

Food Production Daily reports that a new bread containing an antioxidant found in olives has been launched in Spain. The bread contains concentrated hydroxytyrosol, one of the main antioxidants found in olives.  The product is touted as an anti-ageing and heart healthy food.

Hydroxytyrosol is a valuable but troublesome byproduct of olive oil milling. Unfortunately, it and most of the other antioxidants in olives end up in the olive water, not the oil.  They prevent oxidation but also kill bacteria in any kind of attempt to ferment or biologically treat the waste. Many city waste treatment plants refuse to accept olive waste for this reason, creating problems for olive mill operators.

There has been interest for years in finding a way to profitably extract the polyphenol antioxidants, making the disposal of the olive waste easier and creating a valuable food additive at the same time.

Genosa R&D is the supplier of the ingredient in Spain with the trade name of  Hytolive 2.  They have patented a process for extracting the hydroxytyrosol from waste from olive mills.

Puraots, a supplier of bakery ingredients, is distributing the product and has added it to their Nostrum brand bread which is already on the market in Spain.

In the United States, Dr. Roberto Crea at Supremo has been working on similar technology. His company, CreAgri, has marketed the antioxidants and other byproducts removed from olive waste to the cosmetic, nutritional and pharmaceutical industry. Their  dietary supplement containing hydroxytyrosol called Olivenol has been available for some years now. Dr. Crea claims that it contains the natural olive polyphenol with the highest level of free radical protection activity ever reported for any natural antioxidant compound. 

Similar products have appeared on the market from other vendors. They often claim to prevent atherosclerosis, cancer , solar skin damage and damage to the body from smoking.  Their ability to kill bacteria in a test tube has been used as a claim that they are antibacterial when consumed, something which has not been conclusively proved in rigorous scientific studies.

Polyphenol antioxidants are suspected to be one of the important components of the "Mediterranean diet" which is rich in fruits, vegetables and olive oil.  Hopefully this and similar technology will prove to be a health boon and solve an environmental waste disposal problem at the same time.

Recent rules ban the burning of pruned wood and other materials for many San Joaquin Valley orchard and field crops. Farmers have known about the pending ban and sought alternative ways to dispose of the waste material. For example, many farmers now chip or shred orchard prunings. Burning will still be allowed under certain circumstances, especially if needed to halt the spread of plant diseases. Courtesy Food and Farm News

Spain bakes, Olive Yields Shrivel

Drought  in Spain has sent olive oil prices soaring. Spain is the world's largest olive oil producer.  The harvest could fall up to 30% according to current estimates.  This winter's severe frost had already caused problems for producers with about 4 percent of olive trees lost.  Olive oil prices have gone up 20% over last year. The continuing strength of the Euro has also bumped imported oil prices, helping local producers compete.

Land worth Lots

Farmland values in California rose more than 9 percent this year, according to a new report from the U-S Agriculture Department. The annual report placed the average value of California farmland at more than $41-hundred dollars an acre. That’s nearly three times the national average. The U-S-D-A said farmland values rose throughout the country, fueled by low interest rates, high commodity production and prices, and demand for nonagricultural land uses.

Coals to Newcastle

Western Australian company Olea Australis Ltd has succeeded in selling olive oil to Italy. The oil comes from Oleas' Dandaragan plantation in Western Australia where over 1500 tons of olives were pressed for 265,000 liters of extra virgin olive oil.  Several Australian olive groves are being developed as joint ventures with European olive companies.

 

Mail  from the Internet:

Joel Asks: Need something on " methods of irrigation ". Am buying five acres with lots of olive trees in Morocco . There is no irrigation system but a good well . Who sells irrigation equipment, need some sort of piping -spraying system I presume . Pumps ? . What is the best soup to nuts book on growing olives .

Olive Oil News:

We have no recommendations for irrigation suppliers in Morocco but can suggest several good books on olive cultivation. Check out the newest editions of

Pruning and Training Systems for Modern Olive Growing
 

 Olive Production Manual

There may be local university or agricultural officers in Morocco who would be able to help you also  

Bruce Asks: Is there any simple test I can do to determine if oil is extra virgin? I heard that it clouds when chilled. Any ideas?

Olive Oil News responds: Unfortunately, there is no simple chemical test for extra virgin oil.  The taste buds of a certified taster is probably the quickest way to tell if an oil has a defect which would disqualify it from being considered extra virgin.  But even the best tasters cannot detect adulteration with cheaper hazelnut oil or additions of lower grades of refined olive oil.  Your best bet in the US is to look for a dated COOC seal of approval or buy oil which passes IOOC certification. 

For a discussion of clouding, see the newletter article from last December

Matthew Asks: I just wondered which is the best way to plant an actual olive. I've gathered together a few small olives, picked direct from a tree in Italy last week.

Olive Oil News responds: As olives are rarely grown from seeds, you are not going to find much in the way of information on this one. Most trees are grown from rooted cuttings off an existing tree.

Growing an olive from fresh olives is usually a frustrating experience as very few germinate but a tree dropping thousands of olives over hundreds of years will produce many seedlings as most tree owners will attest.  Olives do not need to pass through the intestine of some exotic animal before sprouting like some peculiar species.  The olive must have ripened to a black color on the tree to sprout, and of course can't have been pickled or salted in any way.

Janet Asks: What is the chemical or component in the olive oil that is peppery and sometimes makes people cough? Is it oleic acid? But it really doesn't burn tissue, does it?

Dr. Deane Answers:  Good question, It is not oleic acid because all olive oils have about the same amount and they are not all peppery. Many studies have been done to try to predict a flavor profile based on an oil's chemistry. In "The Handbook of Olive Oil" by Harwood and Arapicio they cite studies done by the authors which show that aglycons are responsible for the bitter and pungent sensory attribute, as well as tyrosol and possibly alpha-tocopherol. The phenols are related to astringent attributes. It is probably the combination of bitterness and astringency that causes the cough.

Paul asks: I have been using Extra Light Olive oil, but I wonder if the polyphenols
have been filtered out, or some of the other benefits have been lost.

Olive Oil News responds: Polyphenols are very small chemicals so they cannot be filtered out of an oil.

Lai asks: I understand olive oil is able to withstand moderate heat before free radicals are formed. Your web site mentions about smoking point and boiling point of olive oil. I would like to know if the smoking point is the temperature at which free radicals start to form?

Olive Oil News responds: As with most chemical reactions, free radical formation can occur at any temperature (even when refrigerated) but is greatly accelerated as the temperature goes up and the longer it stays there. There is no set threshold.

Jennifer asks:  I was recently in Tuscany and took the attached picture of an olive tree. Could you please tell me if each of the tiny green bulbs shown in the picture will become an olive?

How many olives would you expect an average tree to produce in one season?

Olive Oil News responds: Each of the blossoms has the potential to become a fruit. Whether or not they do so is dependent on pollination, weather, water, other stresses on the tree and even variety. 

Olive growers who want oil generally encourage all the olives to develop. For those growing olives for canning, removing many of the small olives using an abscission agent will leave a few large olives which get a higher price per pound. "Fruit set" is a complicated subject:  See also Alternate bearing

As for the total number of olives a tree can produce,  unfortunately there is no "average tree".  Some varieties produce huge quantities on trees the size of a bush while others are dry farmed into impressively tall trees but produce few olives. The size of the olive also varies from less than 2 grams to greater than 6. To complicate more, there is also no "average season" as olive trees usually bear more heavily in alternate years.

University of California experts figured 80 lbs per tree yield for their business cost analyses based on older mission trees.  Hedgerow high yield trees yield 15 to 25 pounds per tree (but the highest yield per acre - up to 6 tons - because of the number of trees).  Large old Mission trees have been known to yield up to 500 pounds each.

According to the World Catalogue of Olive Varieties published by the International Olive Oil Council, a medium olive weighs between 2-4 grams. Taking an average of 3 grams, the hedgerow "bushes"  would yield 3,000 olives.  The big mission tree might have 75,000  olives.
