Abstract

Textile material of polyester or polyamide fibres or filaments is dyed or printed with aqueous padding liquors or printing pastes which contain at least one dispersion dye and is then, directly or after an intermediate drying, brought into contact with liquid methylene chloride. The liquid methylene chloride is applied to the textile material in a separate step by atomising, spraying, brushing, padding, slop-padding or application of a foam thereof. The textile good is then allowed to dwell in order to fix the dye. In respect of dye utilisation (exhaustion), depth of colour and fastness properties the cold fixing process is at least as good as processes which require more expensive apparatus and more energy (for example thermosol or high temperature processes).

Description

(54) PROCESS FOR EXTRACTING VALUABLE NUTRIENT FROM THE LEAVES OF WATER LILY OR WATER HYACINTH (71) I, GODOFREDO GABATAN MONSOD, JR., a Filipino citizen of Quezon City, Philippines, do hereby declare the invention, for which I pray that a patent may be granted to me and the method by which it is to be performed, to be particularly described in and by the following state ment : This invention generally relates to a process of extracting valuable nutrients of the water lily or water hyacinth, Eichhornia crassipes (Mart.) Solms plant, consisting of vitamins, protein and chlorophyll and particularly to a product as a concentrate as produced by the process thereof.

The product obtained by this invention is a concentrate containing the valuable nutrients consisting of vitamins A and B complex of Bl, B2 and niacin, protein and chlorophyll and may typically have the following analysis based on a 100 gram sample Vitamin A as carotene 31.641 mg.

Vitamin Bl 0.32 mg.

Vitamin B2 1.14 mg.

Niacin 4.7 mg.

Protein 23.2 g.

Chlorophyll 4-8 g.

Crude Fibre 2.30 g.

Crude Fats 3.20 g.

Moisture 7.60 g.

Ash 21.50 g.

Non-Free Extract balance The concentrate containing the vitamins, niacin, protein and chlorophyll has been utilized by incorporation in human and animal foodstuffs. Various percentages of such concentrate have been tried and it has been found that 15% by weight is most effective to use. At 10%, the result is quite good but there is still a slight variation of fresh excretion although the odor completely disappears on drying the mixture. At 15% there is still slight variation of the odor from the distinctly obnoxious odor to a slight foul odor.

The feeds or foods wherein 10-15% by weight of the concentrate is incorporated are enriched since the concentrate contains a protein value of about 23.2% protein.

This value is considered high for a certain substance to be present. Protein is one of the very important aspects in the metabolic processes of any body either human or animal.

For human utilization in this invention, a reduced percentage is utilzed since an individual has a maximum requirement for vitamin A consumption. In this case the required amount of vitamin A for an average middle age individual is about 5,000 I.U. per day. Since 100 grams sample of the concentrate will give about 52,735 l.U. of vitamin A, this weight should be reduced to meet such requirements. The concentrate is added to the meal of the individual or molded in the form of a capsule or a tablet. This capsule or tablet can be taken in before or after meals.

The concentrate of the present invention will help to remove the obnoxious odor of human and animal manure so that these said manures can be utilized or re-utilized in another major industry such as the manufacture of fertilizer of which many countries are badly in need.

The concentrate of the present invention will also help to solve health and sanitation problems regarding the unsanitary disposal of the human and animal manures the sense that instead of disposing of it because of its foul odor, it can be stored up and utilized for example by the fertilizer industry.

It is, therefore, the main object of this invention to provide a process of extracting the valuable nutrients of the water lily or water hyacinth plant, consisting of vitamins, protein and chlorophyll, and the product produced by the process of the present; invention.

According to the present invention the vitamins A and B complex of Bl, B2 and niacin together with the protein and chlorophyll as a concentrate are extracted from the leaves of the water lily or water hyacinth plant. The leaves of the said plant are cut down from the stems, collecting and withering the leaves for from 48 to 72 hours at room temperature to reduce its water content, crushing the thus withered leaves in a crushing machine, feeding the crushed leaves into an expeller machine to express the juicy substance containing the valuable nutrients present in the leaves, storing the juicy substance in a settling tank to further reduce its water content and to allow solids to settle, collecting the settled solids by discarding the liquid portion, air-drying the solid portion containing the concentrate in a moderate temperature from 30 to 500C for 1 to 3 days, and pulverizing the dried material on a grinding machine to a particle size that passes through a 50 to 80 mesh U.S.

standard sieve. The pulverized concentrate can be stored in a moisture-free container in either powder, capsule or tablet form which is now ready for use.

WHAT I CLAIM IS:- 1. A process for extracting valuable nutrients including one or more of vitamins A and B complex of B,, B, and niacin, protein and chlorophyll, as a concentrate from the leaves of the water lily or water hyacinth plant which comprises the steps of feeding the crushed and dried leaves into an expeller machine to express the juicy substance containing the valuable nutrients present in the leaves, storing the juicy substance in a settling tank to reduce its water content further and to allow solids to settle, collecting the settled solids by discarding the liquid portion, air drying the solid portion containing the concentrate at temperature from 30 to 500C for 1 to 3 days, and pulverizing the dried material in a grinding machine to a particle size that passes through a 50 to 80 mesh U.S. standard sieve.

2. A process according to claim 1 substantially as herein described.

3. A concentrated product when made by a process according to claim 1 or claim 2.

4. A product according to claim 3 having approximately the following chemical analysis based on 100 gram sample: Vitamin A as carotene 31.641 mg.
