Various Preserved Vegetables


CANNED MUSHROOM

The mushroom commonly used for canning is the I. volvacea species. It looks like a tiny umbrella and its cap is white, occasionally tinged with gray, smooth in texture. This is the most popular mushroom not only in the Philippines, but in the entire Southeast Asian Region. Its growth is well suited to the tropical climate. It is best harvested at button stage and this is approximately on the 11th to the 14th day after spawn planting into bed. These, however, have a relatively short shelf life due to its high moisture content (85 to 95%). To preserve the produce for longer period the best known method applied is canning with 2% brine as medium. The canned product retains its fresh quality and has a shelf life of one year.

The technology for the production of canned mushroom involves the following steps:

1. Sorting for sizes and to remove buttons that do not meet the right specifications for canning; i.e., too mature, too dark or spoiled.
2. Trimming which involves cutting off portions of stem that contain soil or dirt and rather tough.
3. Washing in running tap water to remove all sorts of adhering dirt and clean up the buttons.
4. The buttons are then blanched in boiling water for 3-5 minutes prior to filling into cans with 2% brine.
5. Exhausting of the half-sealed is done to remove all entrapped gases.
6. Sealing is done with the use of an automatic can sealer and this is followed by sterilization at 1-psi for 17 minutes.
7. Cooling under running tap water follows and then the cans are wiped dry and stored.


SAYOTE-PIÑA JAM

1. Peel the sayote slice into thin strips.
2. Peel rare ripe pineapple, remove eyes and chop finely. Crush the fruit (piña in cans can be used as substitute for fresh ones).
3. Mix one part of sliced sayote to one part crushed pineapple.
4. Add ¾ cups refined sugar for every cup of mixture, 1½ tsp. kalamansi juice for every 4 cups of sayote-piña mixture, and stir thoroughly.
5. Boil in a kettle with constant stirring until the mixture is thick.
6. Hot-pack in bottles and seal immediately.


EGGPLANT JAM

1. Boil the eggplant, peel then mash.
2. Add 1½ cups refined sugar to ¾ cups mashed eggplant. Put vanilla flavoring and one tbsp. kalamansi juice for every cup of eggplant puree.
3. Add food color just to retain the color of eggplant.
4. Cook for 30 minutes until right consistency of jam (when it can be scooped out) is attained.
5. Hot-pack in bottles. Cool and store.


MIXED VEGETABLE PICKLES

Ingredients:
green papaya red & green pepper

How to make Cornmeal Soap


Corn has many uses. It can be used as feed for livestock, forage, silage or grain. Industrial uses include transforming the corn into plastics and fabrics. Other uses are in the production of syrups, such as the high fructose corn syrup, a sweetener. It can also be fermented and distilled to produce grain alcohol such as the bourbon whiskey. Recently, with the increase in the prices of oil, corn has been used a source of ethanol as an additive in gasoline (gasohol) for motor fuels to increase the octane rating. Human consumption of corn and cornmeal constitutes a staple food in many regions of the world.

This post will show how corns can be made into soap. Farmers who grow corn may not realize that they can make use of the corn they grow instead of selling it to local merchants. They can add value to their product by making cornmeal soap. The family can use this at home, or they can sell it to their neighbors and earn some money.

About Cornmeal Soap

Cornmeal soap is made from high-quality natural ingredients, including various kinds of vegetable oil, cornmeal and sesame seed. For this reason, this kind of handmade soap is very mild on the skin.

Cornmeal is added to the recipe to improve the quality of the soap. Cornmeal soap helps to unclog the pores and remove excess oil. The rough granules of cornmeal scrub dirt and oil from the skin.

Farmers can make their own cornmeal using the following recipe.

Recipe for Cornmeal Soap

Ingredients

* Coconut oil - 220 g
* Olive oil - 100 g
* Palm oil - 80 g
* Lye - 73 g
* Water - 140 g
* Cornmeal - 20 g
* Sesame seeds - 2.5 g
* Glycerin - 25 g
* Vitamin E - 2 g
* Fragrance - 8 g

Method

* Pour the lye into the water and stir well. Set aside until the temperature falls to 42 C.
* Mix the coconut oil, olive oil and palm oil together in an enamel pot. Heat the oils to a temperature of 42 C.
* Slowly pour the lye solution into the oil mixture and stir well. If the temperature of the mixture falls, heat the mixture up to 42 C again.
* Stir the mixture for up to one hour until it becomes 'trace', (i.e. clear). Then add the glycerin, Vitamin E, cornmeal and sesame seed. Stir for five minutes, then add the fragrance.
* Pour the soap into molds. Leave for at least six hours or overnight.
* Remove the soap from the molds, and cure in a shed for one month. This is to make sure there is no residual effect from the caustic lye.

POINTS FOR BEGINNERS

* The corn should be ground to a fine powder, otherwise it may irritate the skin.
* The sesame seed should be cut into small pieces rather than crushed. This is because crushing squeezes the oil out of the seed, and the ground sesame clumps together.
* You should wear an apron, rubber gloves, and safety goggles to protect yourself from the caustic lye solution.
* Avoid using utensils made of aluminium or other metals, because they react with the caustic lye solution. An earthenware pot should be used to treat the mixture.
* After the lye has been poured into the water, stir it immediately. Otherwise, the lye will clump together and be difficult to dissolve.
* When you pour the caustic lye solution into the oil mixture, make sure that the temperature of the lye and the temperature of the oil are the same.
* Protect the surface of the table you are using with old newspaper.
* The molds should be made of plastic, because it is easier to get the soap out.
* If it is difficult to get the soap out of the molds, put the molds into a freezer for three or four hours. You can then remove the soap easily.
* This recipe yields nine bars of soap, each weighing 60 g. The production cost is approximately US$0.25 per bar. This cost is calculated from the ingredients only, and does not include the cost of kitchen utensils. The recipe can be doubled or tripled, depending on the amount required.
* After the bars have been cured for one month, check the pH of the soap with litmus paper before it is used. The soap should have a pH of 8-10.

This method is not difficult to follow. It may be awkward at first, but when you get used to it, it becomes quite enjoyable. People often enjoy experimenting with the recipe. In Thailand, many groups of farmers from many provinces have become interested in making cornmeal soap.
