The simplest, yoghurt. :smile:


I have drafted a process diagram in two parts:

Tony has started this topic so that members can work through an example of a risk assessment together identifying hazards and control measures to try to improve understanding of the PRP, ORP, CCP cunundrum.

Please get involved whether or not you have Yoghurt knowledge or are an ISO / FSSC 22000 expert.

Regards,
Simon

Only thing i would have done differently is having strike pH and cooling separate. Also i didn't see an addition of sugar.

Obviously this is for a natural stirred yogurt.

Simon asked for it to be kept simple :smile: So Natural Stirred it is. I think we can add to it at a later date.

Sorry GMO missed your post:

Get some milk
Fortify it/adjust the fat level
Pasteurise/Homogenise
Cool to 40 C for Incubation
Add a nice bacteria
Let it grow and generate lactic acid so increasing the acidity/ reducing the pH and coagulating the proteins
Stop the incubation at the right pH say < 4.6 by cooling it. At the same time filtering which will also texturise
Pack it
Cool some more
Send off to customer

On waste, what happens to it as it's a product of animal origin? Can it be sold onto animal feed manufacturers or dried and used for some purpose? There is presumably a lot of calories and value in any waste and a high cost of disposal.

Other prerequisite programmes:

Training & recruitment of suitable staff
Does 13.5 include pre-employment screening and visitor screening?
Traceability in general (even though we don't have rework)

Thanks GMO,

13.6 requires

People known or suspected to be infected with, or carrying, a disease or illness transmissible through food shall be prevented from handling food or materials which come into contact with food.


There are a variety of routes for disposal. I think we should say that the prerequisite is that it is controlled so that it does not affect food safety.

Regards,

Tony

Hi Tony,

It’s certainly an interesting product. :thumbup:

Not sure how typical I am but, being a (totally-non-familiar-with-the-process) reader, I found that I had to do a little more basic process reading to appreciate yr flow chart / comments to GMO. I now hesitate to use the word “simple”, even with irony. :smile:

As a result, I might suggest the basic links and attachment below for anybody else in similar ignorance. Commercial variations of the steps/ numbers mentioned seem to be legion so the content is primarily illustrative although structured, I think, not too different to yr original, more detailed, layout.

Waste yogurt would need to have a Cat note (Cat 1,2 or 3) before it is removed from the manufacturing site.
The Dairy and the receiver needs to be registered with both the local EHO and DEFRA under the Animal By Products legislation

Dear Tony,

Thks for the starter.

Have "quality-safety" / micro. factors been intentionally omitted due unrequired for this specification purpose or are you simply awaiting suggestions ?

For local market only ? I noticed that legal composition data (and other things ??) may sometimes apply depending on destination. Just inquiring. :smile:

Thank you Charles. Yes a bit of a kick start.

I would like members to contribute their ideas as to what they would inlcude. Any suggestions for quality/safety & composition that you have are welcome.

It’s such a great ideato make an example of risk analysis, which would be useful for FS staff overthe whole World.

I’m a little disappointed.There are over 9000 members that are keeping an eye on these forums and askingfor help, taking documents. Isn’t it about time to give a little bit of yourknowledge back?

Come on, don’t be boring. Share. It's Christmas time Posted Image

Tony,

Wouldn't it be better to make some structure for this project?

Are we some place in ISO22000 - 7.3. Preliminary steps to enable hazard analysis?

7.3.3.1 Raw materials, ingredient and product-contact materials

Raw materials (from your product description example)

- Raw milk,

-skimmed milk powder

-milk proteins (???)

7.3.4.

Intended use:

As a snack yoghurt or as an ingredient for cold RTE (f.ex., in dressingfor pasta salads) Not for cooking.

Hi Inesa,

Thanks for your post. :thumbup:

Sorry if the structure wasn't outlined as we are encouraging members to contribute. I see the structure following Section 7 of ISO 22000 although I have a tendancy to jump around (It is one of my favourite songs) a little bit. :smile:


7.1 General - Skipped this
7.2 Prerequisite programmes (PRPs) - we've had contributions on this

So we are here 7.3 Preliminary steps to enable hazard analysis:
7.3.3.2 Characteristics of end products (More contributions welcome - I did this first as our members needed to know a product make up before we move to 7.3.3.1 Raw materials, ingredients and product-contact materials then 7.3.4 Intended use etc. etc.

By the way I did a basic flow diagram (7.3.5.1 Flow diagrams) to give members that are not familiar with the product an idea of the process.

I am not hung up on intended use although I believe that as a snack for children or the old folks would mean that we would want to apply stringent standards/controls.

So if anyone wants to contribute descriptions of ingredients and product-contact materials it would be appreciated:
Milk
Skimmed milk powder
Milk proteins
Printed Polyethylene terephthalate (PET) Pot
Printed Aluminium foil lid

Including the following as appropriate:
a) biological, chemical and physical characteristics
b) composition of formulated ingredients
c) origin
d) method of production
e) packaging and delivery methods
f) storage conditions and shelf life
g) preparation and/or handling before processing
h) food safety-related acceptance criteria or specifications

Kind regards,

Tony

Now you have 8999 awaiting yr input :biggrin:

I started to put some bits together but unfortunately got diverted to easier tasks, :beer: + cake. :x_smile: (No offence Tony, I do agree with Inesa, it's a very worthwhile project, but it is not simple IMO, despite Charles Chew's one line conclusion elsewhere in this forum :whistle: )
