Cooling ‘blood oranges’ could make them even healthier – a bonus for consumers

Cooling ‘blood oranges’ could make them even healthier – a bonus for consumers
2024-06-21
(Press-News.org) An orange teeming with antioxidants and other health benefits may be a shot in the arm for consumers and citrus growers, if the fruit is stored at cool temperatures, a new University of Florida study shows.

 

But it’s too soon to know if the so-called “blood oranges” are a viable crop for the Florida citrus industry, says Ali Sarkhosh, a UF/IFAS associate professor of horticultural sciences. Sarkhosh’s post-doctoral associate Fariborz Habibi explains further.

“Although blood oranges typically command higher prices than other common varieties, such as navel or Valencia oranges, it is unclear if farmers could substantially increase their per-acre income by adding them to their crop selection and then storing them for internal color development,” said Habibi, lead author of the study. “Improved fruit quality from the storage method presents a promising opportunity for the Florida citrus industry. However, further study is needed before recommending anything to growers.”

The fruit is rich in anthocyanins, which have been linked to various health benefits, including anti-inflammatory and antioxidant properties. They also contain other beneficial phytochemicals such as vitamin C, flavonoids and dietary fiber.

“Fruit can also develop internal color under similar conditions at home. However, the fruit in the supermarket should have a good internal color and be ready for consumption,” Sarkhosh said.

For this research, scientists harvested fruit from a research plot at the UF/IFAS North Florida Research and Education Center in Quincy.

Scientists found that storing the blood oranges at 40 to 53 degrees enhances anthocyanin, phenolic content, and antioxidants. When they lowered the temperatures 43 to 46 degrees, they also preserved fruit firmness, weight loss and sugar content.

“Attributes such as firmness are crucial for maintaining the overall quality, texture and taste of the blood oranges during storage,” said Habibi.

Blood oranges get their name from their deep red flesh. Their skin contains a type of antioxidant pigment. The fruit is commonly grown in countries like Italy and Spain, which have the Mediterranean climate – cold, but above 32 degrees -- that helps them grow. In the United States, blood oranges grow primarily in California, but are not grown commercially yet in Florida.

Anthocyanin develops when the fruit is exposed to cold temperatures between 46 and 59 degrees for at least 20 days. Such conditions are rare in Florida’s subtropical climate.

Body image and overall health found important to the sexual health of older gay men, according to new studies

2024-06-21
According to a National Poll on Healthy Aging, 93% of people in the U.S. between 50-80 years old report experiencing at least one form of ageism from other people. Internalized ageism is when a person believes ageist ideas about themselves, such as thinking they had a “senior moment” or thinking they are too old to learn new technology. Internalizing ageist stereotypes can impact older people’s mental and physical health, including sexual health. Various aspects of older adults’ sexual ...

Lab-grown muscles reveal mysteries of rare muscle diseases

Lab-grown muscles reveal mysteries of rare muscle diseases
2024-06-21
DURHAM, N.C. – Biomedical engineers at Duke University have developed a new technique to better understand and test treatments for a group of extremely rare muscle disorders called dysferlinopathy or limb girdle muscular dystrophies 2B (LGMD2B). The approach grows complex, functional 3D muscle tissue from stem cells in the laboratory, creating a platform that replicates patient symptoms and treatment responses. In its debut study, researchers reveal some of the biological mechanisms underlying the characteristic loss of mobility caused by LGMD2B. They also demonstrate that a combination of existing treatments may be able to alleviate some ...

Research finds causal evidence tying cerebral small-vessel disease to Alzheimer’s, dementia

2024-06-21
SAN ANTONIO, June 21, 2024 – Research led by in part by The University of Texas Health Science Center at San Antonio (UT Health San Antonio) finds that the most common cerebral small-vessel disease feature seen in brain magnetic resonance imaging is a primary vascular factor associated with dementia risk. Results of the major international study emphasize the significance of that feature, known as white matter hyperintensity (WMH) burden, in preventive strategies for dementia. “Our findings provide converging evidence that WMH is a major vascular factor ...

Navigating the Pyrocene: Recent Cell Press papers on managing fire risk

2024-06-21
As wildfires become more intense and the fire season grows longer across parts of the world, humans will need to adapt. In this collection of papers from Cell Press journals One Earth and Cell Reports Sustainability, an intersection of fire management researchers comment on what needs to change to ensure we can collaborate across stakeholders in a more fire-resistant future. The papers are publishing in advance of a Cell Press 50th Anniversary sustainabiltiy forum on the topic of “Navigating the Pyrocene: Managing fire risk in a warming world.” The virtual event, free to register, takes place Thursday, July 11, 2024 at 11:00 am ET.

Restoring the Great Salt Lake would have environmental justice as well as ecological benefits

Restoring the Great Salt Lake would have environmental justice as well as ecological benefits
2024-06-21
Inland seas around the world are drying up due to increasing human water use and accelerating climate change, and their desiccation is releasing harmful dust that pollutes the surrounding areas during acute dust storms. Using the Great Salt Lake in Utah as a case study, researchers show that dust exposure was highest among Pacific Islanders and Hispanic people and lower in white people compared to all other racial/ethnic groups, and higher for individuals without a high school diploma. Restoring the lake ...

Scientists document self-propelling oxygen decline in the oceans

2024-06-21
Scientists from the University of Copenhagen have made significant strides in understanding ancient ocean anoxia, with potential insights for today's marine environments. 500 million years ago the so-called Cambrian ‘SPICE’ event made oxygen levels in the oceans drop dramatically. Now, researchers from the University of Copenhagen have investigated how large-scale ocean anoxia, or oxygen-depleted conditions, developed during the event, and its potential consequences today. In the study, titled "Cascading oxygen loss shorewards in the oceans – insights from the Cambrian SPICE event" published in OneEarth ...

2024-06-21
HOUSTON ― Researchers at The University of Texas MD Anderson Cancer Center have demonstrated that therapeutically restoring ‘youthful’ levels of a specific subunit of the telomerase enzyme can significantly reduce the signs and symptoms of aging in preclinical models. If these findings are confirmed in clinical studies, there may be therapeutic implications for age-related diseases such as Alzheimer’s, Parkinson’s, heart disease and cancer. The study, published today in Cell, identified a small molecule compound ...
