The absorption and/or permeation of aroma compounds through polymers is based on the general equation that permeation (P) is a product of diffusion (D) and solubility (S), P = D×S. Consequently, only those aroma compounds with high diffusion and solubility coefficients in respective polymers are likely to be lost through permeation or absorption during storage. The solubility of a compound in a polymer can be estimated simply by making use of the fact that “like dissolves like”. When you want to defrost your frozen orange juice, you can either defrost it in the refrigerator or thaw with water. Thawing through refrigeration actually takes several hours, however it is an effective method. It is best to allow the frozen orange juice to sit in the freezer overnight. Frozen orange juice cubes will thaw a lot faster than a large container of juice. Thawing by refrigeration can take up to half a day. Freezer bags are great for freezing orange juice but there is a simple procedure to follow. Unlike other options of how to freeze your orange juice, you cannot pour your orange juice directly into the freezer bags.

In extrusion blow moulding (EBM), the HDPE resin is first melted in a hot screw and pushed through a steel disk (a die) to form a hollow pipe of polymer known as a parison. When the parison is sufficiently long, the two halves of the bottle mould close around it. Then pressurized air blows into the parison so it takes the shape of the mould, thus the bottle is formed. The bottle is blown with a sealed dome that must be cut off before filling. For Canadian markets, orange juice must be the fruit juice obtained from clean, sound, and mature oranges. [29] The juice must also contain a minimum of 1.20 milliequivalents of free amino acids per 100 millilitres, contain a minimum of 115 milligrams of potassium per 10 milliliters, and possess a minimum absorbance value for total polyphenolics of 0.380. [30] Sweeteners such as sugar, invert sugar, dextrose or glucose solids may be added. The orange juice must have a Brix reading of at least 9.7, excluding the sweetening ingredients, and contain between 0.5 and 1.8 percent of acid by weight calculated as anhydrous citric acid. [29] Added orange essences, orange oils and orange pulp adjusted in accordance with good manufacturing practice is permitted. Orange juice is also permitted to contain sugar, invert sugar, dextrose in dry form, glucose solids, a Class II preservative, amylase, cellulase and pectinase.

PET bottles for aseptic filling do not require heat setting as filling takes place at room temperature. They are usually of lower weight than hot fill bottles and allow more freedom in their design as vacuum panels or similar features are not needed. As a result, bottle costs are lower but aseptic filling is more complex and entails a higher capital investment. 9.6.4

Orange juice prepared from concentrate will last for five to seven days after being prepared for drinking, in the refrigerator, and last for up to one year in the freezer, while still maintaining its best quality. How Do You Thaw Frozen Orange Juice?

Barrier properties against aromas

The best way to thaw out your frozen orange juice is in the fridge. You just need to take it out of the freezer and pop the container into the fridge and allow it to defrost for several hours. It is best to defrost overnight so make sure you plan ahead! If your orange juice has pulp then it is worth straining it before freezing to avoid the grainy texture when you thaw it out. You should know that when a batch of orange juice has been freshly squeezed for freezing, you shouldn’t leave it out for too long – the juice should be frozen shortly after preparation. If you freeze low-quality juice, you’ll get poor results from freezing it. a b c d e Kyriakidis, N.B (November 1999). "Use of pectinesterase for detection of hydrocolloids addition in natural orange juice". Food Hydrocolloids. 13 (6): 497–500. doi: 10.1016/S0268-005X(99)00034-X. Polar polymers like polyester (PET), EVOH and polyamide (PA) basically show very low diffusion coefficients with polar and non-polar aroma compounds. This results in good barrier properties against both types. However, polar polymers are sometimes more difficult to heat-seal than polyolefins.

The amount of time needed to thaw frozen orange juice completely would depend on the quantity of frozen juice to be thawed. However, on average, this can take between two to twelve hours.

How Long Can You Freeze Orange Juice?

In the United Kingdom, orange juice from concentrate is a product of concentrated fruit juice with the addition of water. Any lost flavour or pulp of the orange juice during the initial concentration process may be restored in the final product to be equivalent to an average type of orange juice of the same kind. Any restored flavour or pulp must come from the same species of orange. [33] Sugar may be added to the orange juice for regulating the acidic taste or sweetening, but must not exceed 150g per litre of orange juice. [33] Across the UK, the final orange juice from concentrate product must contain a minimum Brix level of 11.2, excluding the additional sweetening ingredients. [34] [35] Vitamins and minerals may be added to the orange juice in accordance with Regulation (EC) 1925/2006.

Can you freeze orange juice? Yes, you can freeze orange juice. Freezing can be effectively used to preserve the quality of orange juice over a long period of time. Instead of leaving your orange juice out to spoil, just place it in the freezer to keep for months. If done correctly, your orange juice can be preserved for up to 12 months in the freezer.
