Coordinated by IDH, the Sustainable Trade Initiative, and committed to by leading beverage companies, the covenant is a moral, not a legal, obligation. Enabling private sector companies to make proactive, non-competitive improvements across the juice industry supply chain — from raw materials to consumer-based products such as drinks, nectars, juices and smoothies. With the support of AIJN, the European Fruit Juice Association, the companies work together to increase social and environmental sustainability at farm and processing level by rolling out sustainability certifications throughout the supply chain. Globally, fruit juice and nectar consumption is at 38,5 billion liters — and 9,6 billion liters in the EU, the biggest consumption region. As the market grows, we recognize that sustainability is the way forward for the juice industry — and that we can and should play an important role in making our supply chains as healthful as our drinking habits.

IntroductionVIDEO ON THE TOPIC: Safe Handling of Raw Produce and Fresh-Squeezed Fruit and Vegetable Juices

Department of Agriculture's Food Guide Pyramid have increased the public's nutritional awareness. This knowledge, coupled with the consumer's desire for a healthier lifestyle, has greatly impacted the evolution of juice and juice-based drinks over the last few years. It's common knowledge that pure juices derived from fruits and vegetables are healthful, but beverage processors have started adding additional nutrients to pack juices with an even healthier punch. The quest for novelty also influences the design of these products.
Years ago, the juice menu consisted of orange, Concord grape and apple. Occasionally, grapefruit and pineapple were available, and at the time, seemed quite exotic. Now, virtually an infinite variety of juices and juice combinations exists on grocery and convenience-store shelves as well as at juice bars, which are springing up nationwide. New flavor combinations, as well as added ingredients, have helped boost juice's appeal. While oranges and apples lead the league in terms of volume of fruit processed into juice, it's the other fruits that add character to the category.
In addition, developments in aseptic processing, PET polyethylene terephthalate bottles and aseptically filled juice boxes have brought new dimension and markets to the juice industry. Juice is the liquid extracted from the cells of mature fruit. The definition of a mature fruit varies with each type. Typically, sugar and organic acid levels -- and their ratio -- indicate maturity stage. The extracted liquid is composed of water; soluble solids sugars and organic acids ; aroma and flavor compounds; vitamins and minerals; pectic substances; pigments; and, to a very small degree, proteins and fats.
The various sugars -- such as fructose, glucose and sucrose -- combined with a large number of organic acids the top three being citric, malic and tartaric , help give the fruit its characteristic sweetness and tartness.
Add the many flavor and aroma compounds, and a unique fruit flavor results. To complicate matters, just switch around a few of the sugars, acids or flavor compounds, and the outcome is a different variety of the same fruit.
Depending on your point of view, this can be either a windfall or a headache. Juice is extracted from fruit by mechanical means. The extraction process uses various types of presses, either batch or continuous, depending on the type of fruit being processed. Pretreating the fruit increases juice yield. Thick-skinned citrus fruits are cut in halves or quarters prior to pressing; apples and other pomes are ground; and grapes and berries are crushed. Various other pretreatments might include heat and adding enzymes.
Enzymes, particularly in the case of apple-juice production, include cellulase and pectinase. Cellulase degrades the cell walls, whereas pectinase breaks down the pectic substances found within, and between, the cell walls.
The pectins are found between the cellulose and hemicellulose of the cell wall and also in between the cells, acting as the glue that holds them together. Pectinase also decreases juice viscosity.
During mechanical processing, juice thickens due to the pectin content, similar to the thickening that occurs when making jam.
Once the juice has been depectinized, it's much easier to pump and concentrate. Use of pectinase and cellulase enzymes allows for increased juice yields, which isn't possible by simply pressing. While certain added enzymes increase and enhance juice production, naturally occurring enzymes, such as pectinesterase and invertase, must be inactivated by heat.
If these enzymes remain active, juice quality will deteriorate. On occasion though, the naturally occurring pectinesterase can be used to further process clarified juices. Destruction of the pectin will cause the cloud to destabilize, resulting in complete clarification. Enzymes also are used to clarify juice and produce byproducts, such as pulp wash and citrus oils.
Fruit juice can be classified either as cloudy or clarified. Cloudy juices -- often perceived as "natural" -- contain various compounds contributing to the haze. With clarified juices, these compounds are removed by biochemical enzymes , chemical binding agents or physical centrifugation and filtration means.
Fruit type, age and order of application will govern the type and order of the process or processes. Compounds creating the haze include polysaccharides, proteins, polyphenols, pulp and polyvalent cations. The polysaccharides consist of pectin, starch and gums. The polyphenols are primarily pigments and astringency compounds, such as anthocyanins and tannins. The polyvalent cations -- such as iron, copper, aluminum and calcium -- form insoluble complexes with proteins, pectins and polyphenols, and should be removed to produce a more stable product.
For the ready-to-drink RTD market, certain juices, such as orange and grapefruit, are expected to be cloudy. Others, such as grape and apple, are expected to be clear.
Unless the juice is to be bottled and sold as RTD-not-from-concentrate, or fresh-squeezed juice, it's probably concentrated. Benefits are two-fold. Concentration curtails microbial and enzymatic degradation due to either heat treatment, low water activity or low storage temperatures. It reduces storage and transportation costs, because the juice can be reconstituted at the manufacturing site at the time of finished-beverage production.
Processors can then freeze, can or aseptically pack the concentrate. During the evaporation process, volatile aroma compounds are evaporated off with the water. These compounds are recovered, and used to add topnotes to the concentrate or the reconstituted juice. Due to their structure, certain fruits -- such as apricots, passion fruit and papaya -- are inherently difficult to juice.
These fruits are processed into fruit pulps or purees. Sieving separates the edible portion from the skin, seeds and other fibrous matter. Guavas, also difficult to juice, are typically ground whole to produce the puree, which is passed through a fine screen to remove the stone cells.
Either way, the resultant semiliquid can be concentrated, and then frozen or canned, ready to be used for beverage production at a later date. A valuable citrus-industry byproduct is the essential oil. One ton of fruit yields about 8 lbs. Pressing releases oil from the outermost portion of the peel, or "flavedo. The oil is typically mixed with water, due to the extraction method, forming an emulsion.
Centrifugation breaks the emulsion; then the oil is clarified and separated from the waxy portion, resulting in cold-pressed oil. Another type of oil is essence oil, which is recovered during the juice-concentration process.
Either oil may be added back to the juice concentrate to restore its original flavor. Folded oils are oils which have terpenes removed. This process concentrates the remaining compounds. However, because of the loss of the terpenes and other flavor chemicals, a single strength oil and a folded oil -- even if used proportionately -- are not interchangeable.
Surplus oils also are sold to the flavor and fragrance industry. The organic acids create the tartness of a juice. The most common fruit acids are citric, malic and tartaric, but fumaric, succinic and benzoic, and many others may also be found. The total amount of sugar and acids, as well as the ratio of each, changes over the life of the fruit, both while on the plant and in storage. These ratios are reflected in the juice obtained from that particular fruit.
In processing, juice can be corrected for either sugar or acid to conform to the standard of identity for that particular juice. Fruit-juice flavor comes from a number of volatile substances in the oil and aqueous phases. Compounds found in the volatiles include: esters, acids, alcohols, aldehydes, ketones, lactones, and hydrocarbons, and various other miscellaneous organic compounds.
Prior to NLEA implementation, discerning the actual juice content of a beverage was difficult for the consumer. Many products implied that they contained juice.
Now a quick glance at the label answers the question. Orangeades and grapeades are fanciful names which should have orange or grape as the primary fruit, but no legal requirement exists governing use of the term "ade" on a label. Any fruit-flavored beverage may depict fruit on the label, but it also must contain the word "flavored" in the title, so as not to mislead the consumer.
A nectar contains either fruit juice or fruit pulp, combined with water and a sweetener -- either sugar or honey. If necessary, citric or malic acid may be added, in accordance with good manufacturing practices. Acidic, strongly or weakly flavored juices are often made into nectars. Nectars are generally thicker than juice, and possess more mouthfeel. Since most juice beverages have added water, sugar and acid, "nectar" is gaining popularity as a fanciful name.
The different varietals and growing conditions probably account for the differences. For instance, apple juice in the United States has a Brix of exactly So, although a manufacturer may use the same volume of juice, the actual percentage of juice will differ depending upon the exact standards in effect in the country of origin. This can mean the difference between being in compliance with regulations or not.
It also might affect production costs. If a larger-than-necessary juice amount is added, profits decline. Titratable acidity is a measure of all the dissociated and undissociated hydrogen ions. It typically measures the amount of acid found in the juice as citric acid. However, certain juices, such as apple juice, base their titratable acidity on malic acid.
Juice is a drink made from the extraction or pressing of the natural liquid contained in fruit and vegetables. It can also refer to liquids that are flavored with concentrate or other biological food sources, such as meat or seafood , such as clam juice. Juice is commonly consumed as a beverage or used as an ingredient or flavoring in foods or other beverages, as for smoothies. Juice emerged as a popular beverage choice after the development of pasteurization methods enabled its preservation without using fermentation which is used in wine production. Fruit juice consumption on average increases with country income level.

This would help producers to minimise environmental impact while saving in both energy and water consumption — the story of this unmatched innovation unfolds below. The JNSD portion of the beverage industry is stable and conservative in many ways, with industrial practices built up over decades to ensure product safety and production efficiency. However, a range of consumers trends — from increased concerns for health and calls for more natural alternatives to growing environmental awareness -— are putting pressure on JNSD manufacturing to rethink traditional practices. We at Tetra Pak took the challenge and explored how we could make juice production more sustainable while maintaining product safety and shelf-life. We also wanted lower processing costs, to achieve these goals, we needed to find innovative solutions which save energy and water.

The book describes the processing of fruits from four perspectives: a scientific basis, manufacturing and engineering principles, production techniques, and processing of individual fruits. A scientific knowledge of the horticulture, biology, chemistry, and nutrition of fruits forms the foundation. A presentation of technological and engineering principles involved in processing fruits is a prelude to their commercial production. As examples, the manufacture of several categories of fruit products is discussed. The final part of the book discusses individual fruits, covering their harvest to a finished product in a retail market. As a professional reference book replete with the latest research or as a practical textbook filled with example after example of commodity applications, the Handbook of Fruits and Fruit Processing is the current, comprehensive, yet compact resource ideal for the fruit industry.

Over the last few decades, the GCC region has witnessed strong economic growth. This has altered the dietary patterns with increased consumption of processed and fast foods, which in turn have led to higher obesity rates among individuals. As a result, the governments in the region have started several initiatives toward promoting the consumption of healthier food and beverage options. Consequently, there has been an increase in the sales of fruit juices, which are considered a rich source of nutrients. They are also associated with various health benefits such as boosting energy, improving metabolism and reducing cholesterol. This, along with the changing lifestyles, has encouraged consumers to opt for ready-to-drink RTD beverages, as they are easily available and convenient to consume. Besides this, as the GCC countries have a sizable Muslim population, there is a high demand for halal food, which consists of natural, organic and ethically sourced ingredients with proven credentials. Due to this, manufacturers are producing natural fruit juices with no preservatives, colors or artificial additives.
