Fruit blend nectar concentrate 40% blowing, possible causes?

Hi All .

I need assistance , my product is blowing , it is a fruit blend nectar concentrate 40%.

Where do I start my investigation?

What microbiological results are you seeing?
Blowing juice-based products usually makes me think yeast, but it could be other things too.

Would be useful to know:

What's in it - preservatives etc?

Processing - pasteurised?

How is it packed?

How is it stored?

How quickly after production are the problems becoming apparent?

Hi Wendy,

I agree with pHruit, it sounds like Yeast contamination this is usually post processing contamination, but more information is required in order for you to receive sound advice.

Kind regards,

Tony

If it is a UHT type product packed in the usual brik type packaging, then a check of the sealing and for small scratches/pinholes would be a good place to start after the obvious micro contamination checking. Also look at a pattern -  is it the whole  production, only after a certain time, sporadic etc?

Regards

Kathy

Thanks Guys for the feedback. really appreciate it. I sent the contaminated bottles for micro testing , I checked the whole process of manufacturing and found out the there could be a list of where the contamination comes from.

I am waiting for results on sample.
