Effect of extraction methods on the nutritional characteristics of milkfish (Chanos chanos Forsskal) bone powder

Abstract

Milkfish (Chanos chanos forskal) bone is one of underutilized part of milkfish and considered as a waste from “satay bandeng” home industry in Banten. The aim of this research was to determine the effect of different extraction methods on the nutritional characteristics of milkfish bone powder. Milkfish bone powder was prepared using two different extraction methods (alkaline and acid). Milkfish filleting waste was boiled with water for 30 min, removed the remaining flesh from the frames, the frames were boiled with water for 2 hours, autoclaved, boiled in water (MBPW), sodium hydroxide solution 1 N (MBPAl) and hydrocloric acid solution 1 N (MBPAc) for 30 min at 80-90 °C, rinsed with water, dried at 50°C in oven drying for 24 hours, and ground. The observed parameters were % yield, moisture-, protein-, fat-, carbohydrate-, and ash- content. Milkfish bone powder was contained 27.88% protein, 7.85% lipid 51.42% ash, and carbohydrate 7.36%. The milkfish bone power extracted by acidic and alkaline method treatment (MBAc and MBAl, respectively) showed statistical significant difference in yield, protein-, fat-, carbohydrate-, and ash- content. The alkaline and acid- extraction methods showed higher ash content than water extraction method so these method could be used to extract the mineral content from milkfish bone.

Effects of Catfish (Ictalurus punctatus) Bone Powder on Consumers’ Liking, Emotions, and Purchase Intent of Fried Catfish Strips

“…Along with species, processing methods have been shown to influence the composition of fish bone powder [ 28 , 29 ]. Bechtel et al [ 4 ] reported channel catfish frames to contain around 20% lipid and 16% protein.…”

“…Bechtel et al [ 4 ] reported channel catfish frames to contain around 20% lipid and 16% protein. As an alkaline boiling media can denature and hydrolyze proteins and saponify fats [ 29 ], its use for fish bone powder production has been commonly employed, often followed by acid treatment to neutralize the bone mixture [ 5 , 10 , 11 ]. Others have tested the ability of ultrasonic irradiation [ 30 ], proteolytic enzymes and high-pressure wash [ 3 ] to remove excess material from frames.…”

The Effect of Zinc, Shell, and Fishbone Supplementations on Comb Width and Length of Bangkok Rooster

“…Fishbone of freshwater milkfish (Chanos chanos) originated from local markets in Daerah Istimewa Yogyakarta, Indonesia. This research adopted a fishbone processing method from the previous study [3]. Afterward, shell powder originated from the blood clamp (Anadara granosa) shell.…”

“…Fishbone and shell is the leftover of fish and oyster consumption. An accumulation of this waste becomes an environmental problem in several places [2,3]. Fishbone and shell may be useful as a feed supplement to enhance chicken performance.…”

“…Besides testosterone activity, proper protein intake also significantly influences reproductive performance. Fishbone possesses a high protein content beneficial as a protein source for animals [3]. Further study is crucial for the advanced application of shell and fishbone to boost reproductive performance.…”
