In this brief guide, we will answer ‘how do you juice a pineapple?’ Also, we will discuss some health benefits of pineapple and how you can pick the best produce to get the best quality juice.
How do you juice a pineapple?
After you have peeled and removed the eyes of pineapple, cut your pineapple into smaller cubes or chunks that you can juice through two ways.
In a blender – put the pineapple chunks or cubes depending on the size of your blender. Add some sugar or any sweetener based on your preference and the sweetness of your pineapple. Add water depending on the thickness you want and blitz until smooth.
Pass the juice through a fine mesh or cheesecloth to get rid of any leftover flesh or you can leave it as it is all fiber. Serve. You may add ice cubes with other ingredients if you want a slushy type consistency or you may pour your blended juice over ice cubes.
In a fruit juicer – simply feed your pineapple chunks into the fruit juicer until you have run out of pineapples. The juicer will do most of the work. Serve with ice or as it is.
What are the health benefits of pineapple juice?
Pineapples provide the following health benefits;
Just drinking a cup of pineapple provides you with a 30% supply of your daily vitamin C requirement. Vitamin C is a powerful antioxidant that boosts your immunity. The vitamin C content of fresh pineapple juice to be 84.2 mg/100 mL, while that for commercial pineapple juice made from concentrate varied between 12 and 42 mg/100 mL (1).
Reduces cancer risks
Bromelain – a natural enzyme in pineapple that is responsible for the tingling sensation in your mouth. This said enzyme can fight off free radicals and some cancerous cells. It may also help to slow down or stop the growth of cancer cells. The protein molecules from bromelain, such as piperazine chlorcyclizine (CCZ) (factor responsible for immunostimulant activity) and calpain–calpastatin system (CCS) (factor responsible for immunomodulatory activity), have been identified as powerful anticancer agents and could lead to a new class of cancer-fighting drugs (1).
Besides, The pineapple juice contains phenolic acids such as p-coumaric acid, caffeic acid, ferulic acid, sinapic acid, p-coumaroylquinic acid, feruloyl glucose, p-hydroxybenzoic acid, p-hydroxybenzaldehyde, and syringic acid. These phenolic compounds, added to the carotenoid compounds found in pineapple juice act as potent antioxidants and protect against cancer (1).
Anti-inflammatory in nature
Bromelain enzymes present in fresh pineapple juice have anti-inflammatory activities. Bromelain is said to be associated with lowering joint pain and aids in treating injuries (1). Studies reveal that Bromelain detaches particular cell surface molecules associated with lymphocyte and neutrophil migration to the site of inflammation. Also, significantly blocks activation and production of cytokines and inflammatory mediators in cultured leukocytes or human intestinal cells (2).
Aids in proper digestion
A single serving of pineapple in all forms regularly provides you with enough fiber that can also protect you from digestive-related problems like constipation, diarrhea and irritable bowel syndrome. The Bromelin present in pineapple juice also promotes the digestive processes by destroying the proteins in the stomach and intestine; consequently, broken protein molecules can be absorbed by the intestine and enter the bloodstream more rapidly (1).
Pineapple juice can aid in flushing toxins out of your body. This is due to the high amount of antioxidant compounds present in the pineapple juice (1).
How to pick the best pineapple?
There are two main ways to check to see if a pineapple is ripe. The first is to smell the bottom of the pineapple. It should smell fragrant and fresh. If it smells a little bit dirty or musty, the pineapple is getting old.
The second method is to tug at the fronds (leaves at the top). A really ripe pineapple will release a frond or two when pulled on.
How long does fresh pineapple juice last?
Juice is highly susceptible to spoilage, and microbial metabolism leads to deterioration of organoleptic and physicochemical parameters, thereby causing rejection of the product by consumers and financial losses for producers (3).
Freshly made juice is highly perishable therefore it is best to consume the juice within 24 hours. But if you want to stock your juice, it is best to store your juice in an airtight container and then place your container in the fridge.
This way your juice can be kept for 5 to 7 days. This is due to the enzymes in pineapple and sugar that acts as a preservative helping to keep the juice fresh for longer. Quality and shelf life of untreated juice depend on the raw material and the applied processes. Sensory defects during pineapple juice shelf life result from browning and carotenoid destruction. Pineapple juice therefore tastes “fermented”, “alcoholic”, and “chemical” after three to seven days of storage at 4°C (3).
How to make fresh pineapple concentrate?
If you plan on storing for longer than a week, pineapple concentrate is the best way. This will not only preserve your pineapple for a year but also let you enjoy pineapple whenever you wish to.
To make pineapple concentrate all you need is to only add just enough water to get the pineapple blended. Place this concentrate in an airtight container and place it in the fridge. Before serving, just dilute the juice with some water.
Why should you consume homemade pineapple juice?
Fresh juice contains more vitamins and minerals than any premade juice does. For example, previously mentioned vitamin C is a natural antioxidant, that often gets oxidized even before the pack or bottle reaches you while in homemade you still get most of it. Fresh pineapple juice contains a variety of minerals, especially manganese, as well as amino acids, various sugars, vitamins, and polyphenols. It is considered as a functional drink due to its health-promoting properties and has anti-inflammatory, antiatherosclerotic, antiaging, and many other healing properties (1).
Premade juice also contains a high amount of sugar, much more than needed. This only increases your risk of many diseases. In homemade juice, you can add just enough or even substitute with a healthier option.
Manufacturers of premade juice also eliminate all the fiber that is so beneficial for you. They do so to achieve a clearer juice so it appeals to the consumers more.
Premade juice often has added preservatives like sodium benzoate. This keeps the fruit fresh for longer and minimizes quality loss during storage. However, when ingested the preservative doesn’t seize their activity which may lead to constipation. Consumption of sodium benzoate above ADI (5 mg/ kg) resulted in hyperactivity, ADHD and allergic reactions. Sodium benzoate was considered genotoxic, clastogenic, neurotoxic, besides being responsible for changes in cell cycle and for having proven intercalation in the DNA structure (4).
However, there are new trends on juice processing aiming at the elimination of preservatives from the processed juices, while they reduce bacterial contamination with improved shelf life and preservation of antioxidant compounds, vitamins, and minerals. Pasteurization, ultrafiltration, high-pressure homogenization, ultraviolet irradiation, reverse osmosis, freeze drying, and many other techniques are used to improve the quality of pineapple juice (1).
