Up to 7,000 palms can grow per acre.In the Amazon flood plains acai palm treesform a canopy that protect plants from equatorial solar radiation from the sun.

1768: Açai Fruit Reported by Joseph Banks, botanist on Captain James Cook’s, The Endeavour.

1791: Acai Fruit documented by Portuguese explorers.

2,400 Palm Species in the World. Açai palm (Euterpe oleracea) one of 3 species of the Genus, Euterpe only found in the Amazon, especially in flood plains.

Açai fruit grows on palm trees inflorescence.

Immature fruit on inflorescence. Inflorescence with mature açai fruit ready for harvest

Açai palm can produce up to 1,000 kilos of acai fruit in a 7-10 year period.

Fruit is 2.5 cm, ~87% is seed, 13% pulp & skin

Açai palm inflorescencebranchesbeing removed 50 meters above ground to strip acai fruit into baskets.

Published Antioxidant Assays of FD Açai

1) Total ORAC: 1,027 umole TE/gram. Lipophilic ORAC highest of any fruit. Peroxyl radical scavenging capacity highest of

any fruit or vegetable. A few spices are higher. TEAC and FRAP assay’s confirm ORAC assay

(744.0 umole TE/gram; 249.0 umole TE/gram.) 2) Superoxide ORAC (1,614 SOD units). Highest of any

fruit or vegetable.3) High hydroxyl and peroxynitrite scavenging activity

(HORAC & NORAC assay)

4) Both a slow and fast antioxidant. TAO assay.

Human Pharmacokinetic Study ofAçai Juice with Pulp and without Pulp

8 Differences between açai with pulp or without the pulp?

1. A large portion of antioxidants are bound to the fiber in the pulp.

2. Antioxidants in the fiber of the pulp are released in the gut and then absorbed.

3. Juice with pulp had ~45% more antioxidants (total anthocyanins) than juice if the pulp was removed.

4. Juice with pulp was significantly higher in plasma antioxidant levels.

5. Antioxidant compounds were consistently higher for 4 hours.

Clarified (pulp removed) vs Unclarified Açai Juice Study in Healthy Adults

6. Peak antioxidant levels in the blood dropped sooner if pulp is missing.

7. The maximum concentration of antioxidants was 105% higher if the pulp was retained.

8. Half-life of juice with pulp was 110% longer (6.6 hours) than without pulp (3 hours).

Brain Health and Oxidative Stress

The brain only weighs 2% of the body’s weight, but it uses ~20% of the oxygen we breath.

It is susceptible to oxidative stress. Does not possess the same antioxidant defenses

used by the rest of the body. Is rich in fatty acids subject to oxidation.Is high in iron which can act as a catalyst, increases

risk of lipid peroxidation.

Oxidative Stress a Risk Factor Against Brain Health

Lipid peroxidation is associated with progressive damage to brain cells.

To protect against oxidative damage, the brain releases two enzymes.

Catalase converts hydrogen peroxide to harmless water and molecular oxygen.

Superoxide dismutase (SOD) converts superoxide to oxygen and hydrogen peroxide (H2O2), which catalase turns H2O2 into H2O and oxygen.

Açai Pulp Protects Against Oxidative Stress in the Brain

A Brazilian study found evidence that the pulp in açai might protect the brain from free radical damage.

The study pre-treated brain tissues of rats with açai.They exposed the tissues to hydrogen peroxide. The antioxidant polyphenols in acai significantly

reduced the levels of lipid and protein damage caused by H2O2.

Authors concluded that “açai could prevent the development of age-related neurodegenerative diseases.”

Clearly, more research is needed.

Evaluating Antioxidant Activity ofAçai in Human Cells

1) Does açai support healthy immune function? Studied reactive oxygen species formation using

polymorphonuclear cells (ROS PMN) assay 2) Does açai provoke cellular signaling between cells? Used cell-based antioxidant protection in

erythrocyte (CAP-e) assay.

Antioxidant Protection of Human ErythrocytesUsing the CAP-e Assay

1) Açai was able to significantly protect human cells from oxidative damage.

2) Reduce production of free radicals.

3) Reduce proinflammatory activity:

a) fmlp (p<0.001) b) Leukotriene B4 (p<0.05) c) Interlukin-8 (p<0.03)

Study of a complex Açai/fruit juice drink

Questions:1) Are the antioxidants in the juice absorbed after

consumption?2) Does it enter into circulation? 3) Does it enter into cells? 4) Does it protect human cells during oxidative

stress?Will 4 ounces a day of the juice enter human cells and

protect adults from oxidative stress within 4 hours?

Will adults have less lipid peroxidation in their serum within 4 hours during a state of oxidative stress?

Composition of Açai Fruit/Berry JuiceUnclarified, unfiltered, juice with water added only as needed to reconstitute powders, that contained no added extracts to superficially raise ORAC value, only whole fruit/berries including pulp concentrates.

Primary ingredient: Açai (Euterpe oleracea)White grape (Vitis L.) Nashi pear (Pyrus pyrifolia)Acerola (Malpihia glabra)Aronia (Aronia melanocarpa)Purple grape (Vitis L.) Cranberry (Vaccinium macrocarpon)Passion fruit (Passiflora edulis)Apricot (Prunus armeniaca)Prune (Prunus L.) Kiwifruit (Actinidia deliciosa)Blueberry (Vaccinium L.) Wolfberry (Lycium barbarum)Pomegranate (Punica granatum)Lychee (Litchi chinensis)Camu camu (Myrciaria dubia)Pear (Pyrus L.) Banana (Musa acuminata)Bilberry (Vaccinium myrtillus)

Cell-based Antioxidant Protection in Erythrocytes (CAP-e) Assay

�� A novel assay for evaluation of whether antioxidants in foods are capable of penetrating and protecting cells from oxidative damage.

�� Assay is qualitative in principle and does allow for semi-quantitative comparisons to standards such as gallic acid, Trolox, and ascorbic acid.

�� Ideally suited for food and natural products research. (Does not use quercitin as standard.)

The CAP-e constitutes a cell-based model for antioxidant testing that neither has the complexity of the PMN/monocytesassay, nor the risk of misinterpretation of a tumor cell-based assay.

In the CAP-e assay, the cells are exposed to test products in physiological saline.

The cells are allowed time to absorb compounds from the test product.

Any compounds not absorbed by the cells are then removed from the assay by centrifugation and washing.

The cells are exposed to a precursor dye that becomes fluorescent if exposed to oxidative damage.

Subsequently, an oxidative challenge (for example H2O2) is introduced. The fluorescence intensity equals the amount of oxidative damage.

Positive control wells are exposed to oxidative damage without antioxidant protection, and serve as a measure of optimal oxidative damage.

Any reduction of oxidative damage to the cells exposed to the test product is a measure of antioxidant protection.

Human Open Label Pilot Study Randomized, Double-Blind,Placebo-Controlled, Cross-Over Study

(M & F; n=12; 19 to 52 years of age)

ResultsDrinking 4 ounces of an açai/fruit juice complex

resulted in: 1) Increased antioxidant activity; 2) Increased levels of antioxidant compounds

entering cells to protect them from oxidative stress (p<0.03 1st hour; p<0.015 at 2nd hour)

3) 91% of healthy participants had less lipid peroxidation in serum within just 2 hours of consumption compared to placebo (p=0.01).

Results of a pilot and randomized, double-blinded, placebo-controlled, crossover study. J Agricultural Food Chemistry, 2008, 56(18): 8326-8333.

Both Human Studies Published

These results suggest that açai/fruit juice may have a beneficial antioxidant effect on lipids circulating in blood, warranting further research.

However, one should not extrapolate these results to say this would be true for all individuals until larger clinical trials are carried out.
