Proximate, Minerals and Anti-Nutritional Composition of Water Hyacinth (Eichhornia crassipes) Grass

Abstract

The peels of Eichhornia crassipes were evaluated for its proximate and anti-nutritional composition. The results show that the moisture, ash, crude protein, crude lipid, crude fibre, available carbohydrate and energy value were 89.20 ± 0.23% weight wet, 18.20 ± 0.21 %, 8.2 ± 0.18 %, 2.20 ± 0.03 %, 21.56 ± 0.10 %, 49.98 ± 0.48 % and 252.52 ± 0.50 kcal/100g dry weight respectively. The result of minerals analysis showed that the grass is a good source of both macro and micro elements with calcium as predominant. The result shows that the hydrocyanic acid, nitrate, oxalate and phytate were 0.56 ± 0.01 mg/100gDW, 0.38 ± 0.01 mg/100gDW, 0.33 ± 0.05 mg/100gDW and 4.06 ± 1.69 mg/100gDW. The results indicate that if the grass is properly exploited and processed, they could be a high quality and cheap source of carbohydrates and minerals supplement in the formulation of animal feeds.

Phytochemical Composition and Proximate Analysis of the Medicinal Plant Eichhornia crassipes L.

“…It has high cellulose content and act as an alternative fuel. It also serves as raw material for paper manufacturing, vermicompost, potash, biogas production and fish feed formulation (Suleiman et al, 2020). It has the capacity of natural antioxidants for retarding lipids peroxidation (Firoj et al, 2020).…”

Application of water hyacinth flour (Eichhornia crassipes) in artificial feed on the feed quality and feed conversion ratio for bileh fish (Rasbora sp.)

“…Hal ini diduga karena daun eceng gondok masih memiliki kadar protein yang tinggi, dapat dilihat dengan semakin meningkatnya nilai protein pakan seiring bertambahnya dosis penambahan tepung ecek gondok terfermentasi dalam pakan. Eceng gondok memiliki kandungan protein kasar sebesar 8,20 % dan kadar lemak rendah 2,20 % (Sulaeman et al, 2020). Hasil uji proksimat protein pakan disajikan pada Gambar 3.…”

“…Pakan dengan nutrisi seimbang, berkualitas baik, sesuai kebutuhan ikan dan harga ekonomis dapat meningkatkan pertumbuhan dan mewujudkan budidaya ikan berkelanjutan. Eceng gondok berpotensi dimanfaatkan sebagai alternatif sumber protein nabati dalam pembuatan pakan karena ketersediaannya melimpah di Aceh Barat dan memiliki kandungan protein kasar sebesar 8,20 % dan kadar lemak rendah 2,20 % (Sulaeman et al, 2020), serta mengandung asam amino esensial seperti metionin 1,31 %, tryptophan 1,42 %, isoleusin 5,47 % dan lisin 5,06 % (Hontiverros dan Serrano, 2015). Eceng gondok juga mengandung mineral seperti Ca 3,08 %, Mg 0,65 %, K 4,13 % dan P 0,28 % yang dapat menunjang pertumbuhan ikan (Akinwande et al, 2013).…”

Substitution of Water Hyacinth Flour (Eichhornia crassipes) in Feed on The Growth Performance of Bileh Fish (Rasbora sp.)

“…The population density of hyacinth water can be minimized by using it as an alternative raw material for fish feed because its nutritional content is still high. The nutritional content of hyacinth water varies depending on the habitat and season; crude protein content in water hyacinth ranges from 3.3-56.38%, lipids range from 0.65-10.21%, crude fiber ranges from 1.02-21.42%, and carbohydrates ranged from 33.49-58.2% [7][8] [9]. Hyacinth's high crude fiber content can be an inhibiting factor as a raw material for fish feed, hence it must be fermented to increase its nutritional value and digestibility.…”
