Unlock the Power: Fresh Juice from Concentrate in 5 Easy Steps

Citrus juices are rich in components that can help reduce oxidative stress, and inflammation and support both acquired and innate immunity. 

Bioactives such as vitamin C, folate, and polyphenolic substances like hesperetin with its aglycone and the flavonoids of narirutin or naringenin are among these bioactives.

A study was conducted to compare the sugar content of 100% fruit juices that are labeled “no added sugar”. 

The results were within a few degrees Brix and the statistical analysis showed no significant differences.

Juice from Concentrate and Fruit Juice

Fruit juice, an increasingly popular beverage, is made by pressing or crushing fruits to juice.

It’s consumed by many for its perceived benefits and often combined with medication taken by patients. This raises concerns about drug-juice interaction. 

To date, neither non-randomized nor random controlled trials of juice-drug interaction have revealed any adverse clinical outcomes.

RCTs have also been conducted in controlled conditions on healthy volunteers.

No significant interactions between juice and drugs have been identified at this time for drugs with limited therapeutic windows, e.g. cyclosporine). 

In the presence of drugs that have less narrow therapeutic windows, such as apple juice and orange juice (but not GFJ), CYP3A4 activity and P-gp were significantly reduced. Aliskiren’s bioavailability was also decreased.

In multiple prospective cohorts, frequent consumption of 100% juice was associated with lower risks of metabolic syndrome or incident diabetes.

However, the association could depend on how it is defined in dietary assessment questions. 

Cohorts reporting non-defined juice intake show strong associations to abdominal obesity and type-2 diabetes, while those who report only GFJ don’t.

Further research is needed to clarify the effects of different types of fruit juice on body adiposity.

Vegetable Juice Concentrate Vegetable Juice

Fruit and vegetable concentrates have been associated with reduced systemic inflammatory processes, altered gene expression and lower blood lipid levels in overweight/obese adult. 

In a double-blind, placebo-controlled trial, 56 adults consumed F&V concentrate or a placebo for 8 weeks.

They showed significant reductions in total cholesterol and LDL levels but not in tumour necrosis factors-a.

A panel of 50 semi trained panellists evaluated the sensory properties of marula juice using a nine point hedonic system where 9 represents liking extremely and 1 represents disliked extremely. 

The juices made with freshly squeezed fruit were judged to have superior taste, color and flavour, as well as overall acceptability.

F&V concentrate juice scored the lowest on the taste scale because of its bitter-astringent taste.

In a number of prospective cohort studies, a correlation has been found between consuming 100% fruit juices and reducing cardiovascular disease risks.

However, interpretation can be difficult due to the inability to distinguish between non-defined sources and defined ones in the dietary assessment questions used in these studies. The definition of fruit in diet guidelines is often vague, and includes non-defined sources such as canned/bottled fruit drinks and vegetables.

Nut Juice vs. Juice from Concentrate

Fruits and vegetables can be accessed through juicing. Juicing, on the other hand, can increase oxalates in your body if you include certain fruits and vegetables that are high in oxalates. This could lead to health complications, especially if they are not removed before consumption.

The study examined the oxalate levels in green juices made from different spinach recipes, using two types juicers. The results showed that the masticating juicing machine extracted more total and soluble amounts of oxalates than the blender, but these differences were not statistically significant.

For analysis, 109 Valencia cultivar Oranges were collected from November 2015 to April 2016 at different harvest dates and positions of the fruit trees in Matao Region. The samples were then sanitized and weighed before being taken through a non-destructive, fast extraction process. This was done using MIR spectroscopy (MIR) and time domain nuclear magnet resonance (TD NMR) to get soluble pectin solution. Comparing the results with those of the reference method, natural clustering was observed. This allowed for differentiation between groups based on average SPC values.
