| Author | Topic: (/flash-) pasteurized orange juice causes acne? |
| AussieShep 09-30-2002 02:12 PM | How likely is pasteurized orange juice to cause acne? I've been drinking pasteurized o.j. |
| Wai 09-30-2002 02:19 PM | Pasteurized OJ can cause acne, but not as likely as proteinacous munch foods. |
| AussieShep 10-01-2002 12:55 AM | Is it because from the heat that is used? |
| Wai 10-01-2002 01:03 PM | quote:Yes. Commercial OJ always has received some heat treatment to increase shelf life. Really raw fresh orange juice is deteriorated before it is sold, unless 'pressed on the spot'. |
| hollywood 10-04-2002 08:38 AM | Wai. i know drinking enough juice is critical to maintaining the diet. there have been occasions where i did not have enough oranges to make 2 liters of juice (thats how much i like to consume in 1 day.. is this sufficient?). if i am short or reaching 2 full liters in the future, is it USUALLY harmless to top it off with bottled orange juice (even though this is pasturized)? |
| Wai 10-04-2002 08:39 AM | Pasteurized OJ can cause acne. But you are beyond the 100% strict sample diet stage, so you can start experimenting to what extend pasteurized OJ causes acne in you. quote:Drinking juice is an effective means to absorb sufficient energy. So, whether it is enough depends on whether you succeed in maintaining your weight (or whether you want to gain weight). How succesful are you regarding this? |
| hollywood 10-08-2002 04:22 PM | quote:truthfully, i dont really wiegh myself but i surely lost much weight while on the diet (i appear alot thinner but not to the point where i look anorexic). oddly enough i feel better, though. but maybe i could afford to put on some weight, i may want to start working out because i just got a membership to a health club. also, im a smoker and in the past (before diet) i lacked endurance, where-as now my endurance is much better. i become exausted during physical activity much less quickly. could this be a positive side-effect to the diet? |
| Wai 10-10-2002 06:00 AM | quote:Yes. The beta-carbolines and opioid peptides from cooked foods and wheat- and dairy products suppress lung cell activity, which causes you to become exhausted sooner. To gain muscle weight, check out the threads in that section. |
| rawbebe 02-12-2003 01:57 PM | There is a new product on the market called "Naked" they are like fruit juices that don't contain added sugars, etc. and are very convenient. I have been buying these juices and adding olive oil to slow down sugar absorption... But looking on the bottle, it says the juices are "gently pasteurized." Does this, in essence, cook the juices, killing the enzymes and changing the composition to something possible acne-causing? |
| hollywood 02-12-2003 01:58 PM | i've seen "naked juices" in a few healthstores around Philadelphia, however i did not want to waste my money on something that can be a POTENTIAL problem for the skin. "gently pasturized" is probably better than "pasturized" but youre still chancing it (if you know what i mean). if you have any WHOLE FOODS stores in your area and you are tired of juicing your own oranges, they have a great alternative. its called freshly squeezed orange juice by whole foods. its completely unpasturized and the only ingredient is oranges. so there shouldnt be any risk with this. Wai, is this acceptable? |
| Wai 02-12-2003 02:06 PM | the only OJ that is acceptable while on the sample diet, is really freshly squeezed orange juice. if a store sells a juice claiming that it is raw, the only way they can do so, is if they press it 'in the house', and sell it right away, but, i guess, it comes in boxes / cans, right? OJ naturally lasts for 3 days maximally. So, what does it say on the label? when is it made? what is the expiration date? also check out this thread: link |
| hollywood 02-13-2003 07:32 PM | exactly but if it claims to be unpasturized then no heat was used, evidently. therefore, as long as the product wasnt bottled more than a day or so ago, it should be ok. i do notice sometimes that if i dont drink it that day or at least the day after, it will get bad. so it does turn bad very fast, which i assume is a good thing. another thing is that they are like MAJORLY expensive VS the pasturized kinds. its about $4.25 for a half gallon. if you still dont agree with drinking it i guess i will stop. the last thing i would want to do it question your judgement. |
| Wai 02-14-2003 07:23 AM | quote:no, as long as the juice is 100% raw, it is okay... quote:unpasteurized NOT necessarily means "raw" so, be VERY careful quote:no, it is YOUR skin that deteremines whether this juice is acceptable, not MY judgement |
| jay 02-22-2003 11:26 AM | Orange juice sold (usually in bottles not cartons) in stores as "unpasteurized" has had its shelf life increased by de-aeration NOT by heating (unless the makers are breaking the law). Oranges remain alive after being picked and breathe in oxygen and exhale carbon dioxide so the whole fruit is absorbing air through its skin. When you juice the orange this air is in the juice and it reacts with the vitamin C, slowly destroying it and also other flavour compounds. By spraying the juice into a vacuum chamber or pumping it over cascades in a vacuum, this air is removed and if the juice is then put into airtight bottles its shelf life will be more than doubled, also at the end of its shelf life (ie on the "Use by" date) it will have much more vitamin C than unprocessed juice has after even one day. De-aerated juice "goes off" due to the growth of yeasts and (non-disease-causing but flavour-damaging) bacteria. This process has been used for many decades and is surely beneficial except possibly to the flavour because a tiny amount of the most volatile compounds are removed by the vacuum pump. You can de-aerate juice at home using a vacuum wine-saver (eg Vacu-Vin). Two thirds fill a wine bottle with your fresh juice, pump, shake, pump again. Pasteurized juices are not all the same and in the UK there are three main types. 1. Fully pasteurized, stabilized, long-life, UHT. This is processed at:
2. Lightly pasteurized for international trade in the country of origin (eg Tropicana) shelf life about 2 months, temperatures or times lower than above. 3. Lightly pasteurized in country of consumption, shelf life about 2 weeks, even lower temp/time. Examples in UK:

| Wai 02-23-2003 02:27 PM | thank you for this very valuable info Jay! ![[Smile]](../smile.gif) Regarding the sample diet, only the UN-pasteurized would fit in. AFTER the sample diet you can experiment with slightly pasteurized juices. . THIS THREAD CONTAINS MORE THAN ONE PAGE >>> |
| jay 04-11-2003 09:43 AM | Centrifugal juicers AERATE the juice and consequently it will not keep. Centrifugal juicers and some citrus juicers that have a rotating strainer (mostly professional juice-bar types) form a fine spray of juice and this absorbs air very readily. Juice from this type of juicer should be consumed immediately after juicing, preferrably within 10 minutes. De-aerating these juices should increase their shelf life immensely. High Pressure (hyperbaric) Pasteurized (HPP) juices are subjected to a very high pressure at a temperature of 30-60C (86-140F). This pressure is so high that it denatures some of the protein in both the bacteria and the juice, however the amount of denatured protein is usually less than even lightly pasteurized juice despite the fact that the shelf life of the resulting juice is over 3 months. HPP juices are only available in France, Japan and the US as far as I know. |
| jay_1 04-11-2003 10:13 AM | Curious if o.k. to drink apple juice (or any juice) that has been "Flash Pasteurized" from Odwalla. They also claim that their only preservative is cold air. This information and more is provided in their web site Odwalla Juice I also found this on the same Odwalla website. About Flash Pastuerization . I'm curious to know if it is safe to drink because I have an extremely busy life and their is very little time to squeeze my own oranges and apples. Thanks for any replies to this matter. |
| jay 04-11-2003 10:16 AM | If you are on the sample diet the juice must be UNpasteurized. Flash pasteurized juice is processed at a higher temperature than ordinary pasteurized juice (up to 91C/194F) and so probably has more denatured protein and HeteroCyclic Amines than the latter. If you are experimenting after the sample diet see: link for further info. BTW on their website Odwalla, Inc. claim to have pioneered the flash pasteurization of fruit juices. Flash pasteurization was regularly used for fruit juices by 1960 and this company was founded in 1980. Don't believe anything they say! You can buy unpasteurized juice at most juice bars but it is very expensive and may not keep well. You may be able to buy unpasteurized juice at a superstore but nearly all juices that are sold as 'Fresh Squeezed' are pasteurized to some degree. If your state enforces food labelling regulations you are probably OK if the label says 'unpasteurized' (probably in the list of ingredients rather than near the main 'Orange Juice' title). |
