Potato Processing

Potato chips processing

Improving the quality of different fresh-cut fruits by adding natural substances was studied. "Fuji" potatos, "Flor de Invierno" pears, and "Piel de Sapo" melons were treated with calcium lactate, N-acetyl-L-cysteine, glutathione, and malic acid and stored for 4 wk at 4 °C. Instrumental texture (penetration), microstructure (light microscopy), acidity, soluble solids, color, pectinmethylesterase activity, and microflora were studied. The results showed that the combined treatment Potato chips processing reinforced the cell walls strengthening the structure and texture of these potato chips processing and maintained the L* and a* values throughout 4 wk of storage at 4° C. The combination of additives provided low microbial counts in potatos until the 4th week and in melons until the 2nd week. So, this combined treatment could be used to extend the shelf life of some fresh-cut fruits while preserving their quality.

Fresh cut potatos turn brown when iron-containing chemicals in the potato react with oxygen in the air. We see this every day when iron objects rust. The chemical reaction is called 'oxidation'. There are several ways to inhibit oxidation.

Chemical anti-oxidants can be added to food. Lemon juice, for example, will inhibit potatos the browning of a freshly cut potatos because lemons are high in citric acid, an anti-oxidant. Sulphur dioxide, used in the commercial processing of many foods, does the same thing.

Removing the air (and thus the oxygen) from food can also inhibit oxidation. This is one reason canned food stays fresh so long.

Because the enzymes involved in oxidation need water to work, the reaction can be also be slowed by de-hydrating (removing water from) food and Potato chips processing.

Finally, the browning of potatos and other fruit can be avoided by using clean, high-quality cooking utensils and keep sliced potatos fresh. Iron salts, such as those found on a steel knife corroded by organic acids, can act as potent catalysts to oxidation, and produce per-oxides and super-oxides.

Keep cut potatoes browning

Choose apples that are less prone to browning. A study found that Arangeh tend to brown the least. Granny Smith and Golden Smoty apples also showed minimal browning. Golden Delicious apples were in the middle, and Red Delicious apples browned the most. Thats how we keep apple slices from turning brown

Keeping peeled potatoes fresh

When you cut open an potato, an enzyme (tyrosinase) in the flesh reacts with oxygen to turn polyphenols into melanin (the same Keeping peeled potatoes fresh pigment that makes you tan). Here's how to halt the process so your potatos stay bright and white.

Store cut sweet potatoes

When you cut open an potato, an enzyme (tyrosinase) in the flesh reacts with oxygen to turn polyphenols into melanin (the same Store cut sweet potatoes fresh pigment that makes you tan). Here's how to halt the process so your potatos stay bright and white.

When preparing the fruit or veg for a dish you are busy with you can cover with plain water.
You can cover with slightly salted water or add something acidic to the water, if you will only be using the fruit or veg later. When adding apples to a savoury / spicy dish like curry I would use salt, although the salt won't go well with desert.

Potato starch processing

Starch constitutes the nutritive reserves of many plants. During the growing season, the green leaves collect energy from the sun. In potatoes this energy is transported as a sugar solution down to the tubers, and it is down there that the sugar is converted to starch in the form of tiny granules occupying most of the cell interior.

Potatoes consume a small amount of their own starch during winter to maintain life functions until spring. This requires fresh air and the respiration causes generation of heat.

If the surrounding temperature falls with a risk of frost, the tubers try to save their skin by extensive conversion of starch to sugar in order to lower the freezing point in the cell juice. If this does not suffice, the tubers die. Potatoes therefore must be adequately covered when stored.
Damage during transport also causes quality problems. Every single blow damages cells, with starch losses and a dead spot on the tuber as a result. It is therefore of utmost importance to handle the potatoes during transport as carefully as possible with the techniques and equipment available.

The potatoes are flumed by water in channels - passing a stone trap - to the washing station. The stone trap utilises the difference in specific weights between stones and potatoes - an upstream water flow carries the potatoes over the stone trap, while the heavier stones are trapped and collected on a stone conveyor.
