Collagen peptide GB is coming, but for how to choose good raw materials you really clear?

On October 25,2016,the National Health and Family Planning Commission(NHFPC)publicly solicited public opinions on the"National Standard for Food Safety Collagen Peptide"(hereinafter referred to as"National Standard").This means that for a long time"standard"problem in many enterprises is coming to an end,the national standard come on stage will play a positive promoting role to the development of the industry,but for terminal enterprise,not"disorder"the coherence of the law is not the same as the standard on the level of raw material selection,seeking differentiation on the baselines of national standard of high quality raw materials,It has become an urgent matter in front of terminal enterprises.

It's a collagen peptide,not a collagen.

Before the National standard(draft for comment)was issued,there were roughly four reference standards related to collagen/collagen peptide.They are QB2732-2005 hydrolyzed collagen industry standard,QB/T2879-2007 Marine fish oligopeptide powder industry standard,GB/T22729-2008 Marine fish oligopeptide powder national standard and SB10634-2011 freshwater fish collagen peptide powder industry standard.Apart from the different sources,the standard"target"itself can be divided into"hydrolyzed collagen","oligopeptide powder"and"collagen peptide powder".And the national standard will be"target"clearly on the"collagen peptide"rather than"collagen"or other,its intention can be seen.

Collagen is a kind of macromolecular protein ubiquitous in animals,mainly existing in the connective tissue(bone,cartilage,skin,tendon,toughness,etc.),accounting for 25%-30%of the protein in mammals,equivalent to 6%of body weight.The skin of many Marine organisms,such as fish,accounts for even more than 80%of their protein content.Collagen peptide is a mixture of low molecular weight collagen peptides prepared from collagen by enzymatic hydrolysis,and its molecular weight distribution is generally below 10000 Dalton.In addition to the many physiological activities of collagen,collagen peptide also has some properties that collagen does not have.Compared with collagen,collagen peptide has lower molecular weight and better digestibility.

For a long time,collagen was thought to have many benefits for skin,joints,and more.In fact,collagen is composed of a unique three-strand superhelix,which is very stable in nature.It cannot be decomposed by ordinary processing temperature and short time heating,which makes it difficult to digest and absorb,and is not easy to be fully utilized by the human body.In recent years,it has been found that some collagen hydrolysates with smaller molecular weight,collectively known as collagen peptides,can really exert physiological effects.At present,many international and domestic studies have shown that collagen peptide can exert various functions to the greatest extent.Perhaps it is on this basis that the national standard is defined as"collagen peptide"rather than collagen.

"Hydroxyproline"is not the"only Active Ingredient"

Three years ago,a health care product company was questioned about the authenticity of its products because hydroxyproline was not detected in the terminal products.The challenged company felt wronged,so it denied the"reliability"of using the amount of hydroxyproline to evaluate the authenticity of products on the grounds that the signature ingredient was oligopeptide-not hydroxyproline.It is also especially stated that the products involved are Marine fish skin collagen oligopeptide oral solution,not collagen oral solution,which is fundamentally different from each other,and it is unprofessional to evaluate oligopeptide with the method of evaluating collagen.

Now it seems that such doubts and justifications will be gradually sold as the national standard.The new National Standard clearly stipulates the physical and chemical indexes of collagen peptide,which requires hydroxyproline(based on dry basis)/(g/100g)≥3.0.

Why should the national standard specifically mention hydroxyproline content?It probably starts with the composition of collagen.Collagen is made up of 18 amino acids,of which hydroxyproline is only one.However,because it is rare in some other common proteins(such as soy protein),it can be used as one of the characteristic amino acids.The content of hydroxyproline is determined by the raw material source of this collagen.Moreover,in the same raw material,the content of hydroxyproline in different types of collagen is also different.Therefore,as far as the national standard is concerned,hydroxyproline is only one of the characteristic components of collagen,but not the only functional component.

Cross the national standard threshold details determine success or failure

Once the national standard is finalized and the standard is issued,molecular weight and hydroxyproline will no longer be the indicators to judge the quality of collagen peptide products,but as the basic threshold.In other words,in the future,as long as the product is in line with the national standard,there will be no dispute over the composition and content.So,what does the end health product/dietary supplement company need to distinguish between the collagen peptide raw materials themselves?This is probably from the source of collagen peptide raw materials.

For terminal enterprises,in the future,meeting national standards is only a necessary condition for supplier screening.The safety of the raw material source,production process and quality management and other details will become the key elements to judge the quality of the product.

When the standard has not been unified,we can barely use the development of standard regulations for product quality excuse.After the dust of the new national standard is settled,the standard will no longer be an obstacle to the development of the industry.The truly high-quality collagen peptide products must start with details and live with strength.
