Analysis and evaluation of muscle nutrition level of grass carp with 13 quality certifications
摘要
Abstract
In order to support the nutritional quality level of quality certified grass carp,a qualified testing institution was commissioned to conduct 30 nutritional tests on 13 quality certified grass carp produced from 13 Guangxi fishery pollution-free agricultural product production units.The results are(omitted from previous data):(1)The average(range)of ordinary nutritional components is:energy 374.15 KJ/100 g(366.14-456.78),protein 18.80％(15.0％-21.0％),fat 0.8％(0.1％-2.4％),ash content 1.14％(0.78％-1.30％),dietary fiber 0.86％(0.28％-2.35％),and carbohydrates 1.29％(0.17％-3.71％);(2)The average(range)of the top eight amino acids in high and low order detected is:glutamic acid(G1u)3.16％(2.74％-3.54％)＞aspartic acid(Asp)1.95％(1.59％-2.36％)＞lysine(Lys)1.85％(1.56％-2.16％)＞leucine(Leu)1.41％(1.18％-1.56％)＞arginine(Arg)1.18％(1.05％-1.30％)＞alanine(Ala)1.09％(0.90％-1.25％)＞valine(Val)0.88％(0.74％-0.98％)＞histidine(His)0.85％(0.56％-2.17％).Among them,the proportion of essential amino acids to total amino acids(EAA/TAA)is 37.54％-41.11％,and the proportion of essential amino acids to non essential amino acids(EAA/NAA)is 75.32％-86.47％,which meets the FAO/WHO ideal protein standard and whole egg protein standard;The six types of umami amino acids account for 43.91％-51.53％of the total amino acids(fresh sample),and the F-value is 2.28-2.49,which is close to the healthy human body value;The amino acid score(AAS)ranges from 0.85 to 1.66,the chemical score(CS)ranges from 0.65 to 1.50,and the essential amino acid index(EAAI)ranges from 0.78 to 0.98,indicating a balanced composition of amino acids and a rich and balanced composition of essential amino acids suitable for human absorption;(3)The average(range)of the 6 min-erals detected is:selenium 4.14 μ g/100 g(Tr-2 μg/100 g),zinc 0.43 mg/100 g(0.22-1.00 mg/100 g),iron 0.73 mg/100 g(0.31-4.34 mg/100 g),calcium 22.49 mg/100 g(3.5-54.2 mg/100 g),magnesium 15.18 mg/100 g(11.40-17.10 mg/100 g),sodium 29.34 mg/100 g(18.80-57.60 mg/100 g).Research has shown that 13 quality certified grass carp muscles are rich in nutrients and are high protein foods.They have a balanced ami-no acid composition and are a high-quality protein source.The essential amino acid composition is rich and suitable for human absorption,and they are also high-quality aquatic products rich in various trace minerals.This study pro-vides a nutritional quality foundation for local enterprises to upgrade from pollution-free grass carp brands to higher quality grass carp brands.[Chinese Fishery Quality and Standards,2024,14(06):27-37]关键词
