( September 2018) ( Learn how and when to remove this template message) Pulpy juice really doesn’t freeze well as the liquid and pulpy bits tend to crystalise, and you end up with juice that is grainy and a little odd in texture. Seal quality is of utmost importance in aseptic systems to prevent the entry of microorganisms. When filling orange juice with a high content of floating pulp, special consideration should be given to the transversal sealing. 9.6.2
Glass bottles If a 200ml glass of orange juice has 10 grams of sugar per 100 ml, it will have at least 20 grams of sugar in a glass

We asked a panel of 64 consumers to blind-taste Innocent and Tropicana smooth orange juice alongside 10 cheaper own-label juices from supermarkets including Aldi and Asda and Tesco. I can recount several hot days when I had to down a couple glasses of cold orange juice; it’s always such a refreshing feeling. Orange juice, whether store-bought or freshly squeezed, is always delicious.

Aside from the unpleasant taste and odor, it is very unsafe to consume orange juice that’s gone bad. It is not possible to correlate directly the relative concentration of an aroma compound with its importance for flavour. For example, a compound that is 90% w/w of the aroma fraction may contribute very little to the flavour, whereas a compound that has only a 0.001% w/w share of the aroma fraction may have a very high impact on the flavour sensation. The reason is that the human nose and taste buds can respond very differently to compounds of different chemical structure. A big-brand orange juice came top in our taste test, but several cheaper supermarket rivals aren't far behind and cost much less.

As of 2020, consumption of orange juice was under preliminary research for the potential to improve nutrition and affect cardiovascular diseases. [11] Commercial orange juice and concentrate Frozen concentrated orange juice

Figure 9.4 shows the effect of temperature on the browning of orange concentrate. It is evident that browning results mainly from long-term storage at temperatures higher than 12°C. The suspension is unstable when the zeta potential is less than 25 mv in magnitude. Zeta potential is a measure of the magnitude of electrostatic forces between particles, which affect repulsion, and attraction between particles. A low zeta value signifies that the repulsive forces will not be able to overcome Van der Waals attractions between cloud particles and thus begin to agglomerate. Agglomeration of cloud particles will prevent free flow characteristics, which is essential in the juice. A high zeta potential will inhibit particle-particle agglomeration and maintain the free flowing nature as well as uniform dispersion in orange juice.

The robustness of PET bottles compared to glass is obvious, but they do not provide as good an oxygen barrier as glass. Standard PET bottles give a shelf life for orange juice of about three to four months; large volume bottles give a longer period. The inclusion of active (oxygen scavengers) and passive barriers in PET bottles may extend shelf life up to 12 months and more. Cold pressing: This is seen as the premier production method that enables juice to hold onto the full spectrum of antioxidants, nutrients, vitamins and minerals(and taste) from the fruit.However, keeping temperatures low also gives rise to the potential for bacteria to grow, giving cold-pressed juice a much shorter shelf life. It also raises the price point quite significantly. Orange juice contains harmful microorganisms that reproduce, even though you store it properly. When they’ve multiplied enough, they can cause diarrhea, stomach cramps, vomiting, and nausea when consumed. Orange juice is a suspension that consists of heterogeneous particles in a clear serum. A serum is the clear supernatant after the precipitation of the cloud through centrifugation. The previously mentioned cloud makes up a large part of the suspension.
