OPTOD Optical Dissolved Oxygen & Temperature Sensor Optical technology:
The OPTOD sensor is based on luminescent optical technology and is approved by the ASTM International Standard Method D888-05.
Without calibration requirements, and thanks to an ultra low power technology, the OPTOD sensor is suitable for field work as well as long and short term monitoring.
With no oxygen consumption, this technology gives an accurate measure in all situations, even in very low oxygen concentrations.
Digital Technology:
The "smart" OPTOD sensor stores calibration and history data within the sensor. This allows you a "plug and play" system without re-calibration.
Digitally optimised measurement technology
* Optical luminescence technology requires minimal maintenance
* Digital sensor: Modbus RS-485
* No calibration required and therefore little to no drift occurs
* Robust and Watertight

Las 4NF- Lactose Substitute Non- Fat Solid is an Enzymatically Modified, Clean Label, Vegan, Gluten-Free, Plant-based and Non-GMO
starch used as a special additive for improving texture of Paneer. It is 100% naturally made which does not have any preservatives and Mono sodium Glutamate (MSG).
APPLICATIONS
1. Milk is first heated (pasteurizing) to 85�°C and held for 12 minutes.
2. Add 2% to 20% of LAS 4NF based on the Protein Content of the Milk to
the pasteurized milk and stir slowly to ensure full dissolving at 80C.
3. LAS 4NF itself contains coagulant. If necessary add coagulant as per the costumer requirement slowly to the milk by slow stirring, maintaining the
temperature at 70�° C.
4. Keep Slow stirring for complete separation of solids and whey.
(Indication: Whey will turn to light green color and small lumps of solids
will settle down)
5. The whey water is filtered through a fine mesh of muslin cloth. The separated particles remain in muslin cloth and it is held in hoofer.
6. Apply pressure on the covered solid spread evenly on hoofer, with a flat lid in lay till water droplets stop.
7. Then the Paneer is pre-cooled in pure water at room temperature for 10 mins or till the external sides can be held in hand water for 10 mins , then
dip in chilled water for 4 hours.
DOSAGE
Use 2 to 20% of LAS 4NF of total batch size, based on the protein content of the milk. For lower protein content in the milk higher LAS 4NF need
to be used.

APPLICATIONS:
As a Thickener:Tapioca starch 9M can be used as a thickener and in fruit pies, soups, puddings, breads, sauces, soy and meat products. It completely dissolves in the product when used as a thickener. Tapioca starch 9M thickens quickly, and at are relatively low temperature.
As a Stabilizing Agent:Tapioca starch 9M can with stand long cooking times without breaking down. Products made with tapioca will not lose their quality when frozen or reheated because tapioca retains its thickening capabilities throughout these processes.
In Baking and Confectionery:Chocolates, biscuits, cakes, ice creams, and vermicelli contain tapioca starch, and it is preferred due to its better gelling properties and usability as a thickening and bodying agent. The mixes break less, making it easier to mould the bakery and pastry products during production.Tapioca starch 9M is used in confectionery for different purposes such as gelling, texture stabilizing, foam strengthening, crystal growth control, adhesion, film foaming and glazing.
In Sauce and Ketchup Industry:Sauces made with corn starch turn spongy when frozen but tapiocastarch 9M gives good stability in frozen sauces. Tapioca starch 9M is a good choice if you want to correct a sauce just for preserving it.
In Beverage Industry:Tapioca starch 9M based sweeteners are preferred to sucrose inbeverages for their improved processing characteristics and product enhancing properties.
In Fillings and Pies:Tapioca starch 9M gives food a transparent, glistening sheen, whichlooks excellent in a pie filling. Tapioca starch 9M creates a perfectly smooth filling and imparts a high gloss for a tasty-looking food. It�¢??s the perfect product to use with high-acid fruits or a lattice-type pie.
For a creamy texture:Desserts, ice-creams, cheeses and other dairy products made withTapioca starch 9M become creamier, producing a more pleasant sensation in the mouth.
For a Characteristic texture:Tapioca starch 9M provides softer and spongier textures than otherthickeners. It gives the bread an airy feeling so typical of traditional bread and the crust becomes crisper.
Higher density for the meat industry:Tapioca starch 9M is a very suitable alternative to potato starch for meat industries, due to its high binding capacity.
