Types of Natural Extracts

The natural extracts produced by our company mainly include the following types:

LM Pectin

LM Pectin, or Low Methoxyl Pectin, is a type of pectin that has a lower degree of esterification (less than 50%) than high methoxyl pectin. It's derived from citrus peels and is used as a gelling agent, thickening agent, and stabilizer in food, particularly in low-sugar applications. LM Pectin requires calcium ions to form a gel, making it suitable for low- or no-sugar jams and jellies.

Serine

Serine is a non-essential amino acid vital for the human body, playing a critical role in various metabolic processes. It is involved in the synthesis of proteins, the formation of cell membranes, and the metabolism of fats. Serine is also essential for the production of neurotransmitters that contribute to the proper functioning of the brain and nervous system. Recognized for its role in cognitive health and muscle development, serine supports overall well-being and physiological functions.

Advantages of Natural Extracts

LM Pectin

LM pectin have many advantages, including:

Texture and stability: Lm pectin forms a softer, more elastic gel compared to hm pectin, making it suitable for applications where a delicate texture is desired, such as dairy products.

Flexibility in formulations: It doesn't depend on high sugar or acid levels to set, allowing food formulators to create a wider variety of products with different ph levels and sugar content.

Increased thixotropy: Lm pectin can exhibit increased thixotropy, meaning it can thicken or thin in response to shear stress, which can be beneficial in certain applications.

Cold-set gels: Lm pectin can form gels through calcium diffusion into the filling, allowing for cold-setting applications.

Serine

Serine have many advantages, including:

Cognitive health: Supports mental performance and brain function.

Muscle growth: Plays a role in the growth and maintenance of muscle tissues.

Metabolic function: Involved in the metabolism of fats and the synthesis of important cellular components.

Application of Natural Extracts

LM Pectin
LM pectin can be used for a variety of purposes, including: Widely be used as thickener; gelling agent; stabilizer; emulsifier. Pectin is used in the manufacture of jams, jellies, egg yolks sauce, essential oil stabilizers, to prevent cake hardening, to improve the quality of cheese, and to make juice powder.

Serine
Serine can be used for a variety of purposes, including: Schizophrenia. Taking D-serine by mouth along with standard antipsychotic therapy might improve symptoms of schizophrenia. But taking D-serine alone doesn't work as well as standard treatments. There is interest in using serine for a number of other purposes, but there isn't enough reliable information to say whether it might be helpful.

Special Precautions and Warnings of Serine

L-serine is commonly consumed in foods. The typical diet provides about 3.5-8 grams daily. Serine is possibly safe when used in higher doses as medicine. L-serine in doses up to 25 grams daily for up to 1 year, or D-serine in doses of 2-4 grams daily for up to 4 weeks, have been used safely. Side effects might include upset stomach and bloating.

Serine is possibly unsafe when taken in very high doses, such as 25 grams or more of L-serine daily or 8 grams or more of D-serine daily. High doses might lead to increased stomach side effects and seizures.

FAQ

Q: What is LM pectin used for?

A: LM pectin is used to help provide a gelled or creamy texture in acidic (including fermented) and neutral dairy & plant-based dairy products. HM pectin is used to protect the proteins in acidic conditions and provide a pleasant mouthfeel.

Q: What is the difference between pectin NH and pectin LM?

A: Pectin NH is a type of LM pectin that has been modified to set without the need for much calcium (pectin NH gels with calcium but unlike other LM pectins it requires much less calcium). Because there is less calcium in the gel, pectin NH is thermally reversible.

Q: What does pectin do to the gut?

A: Specific pectin structures may contribute to intestinal homeostasis by stimulating the growth of microbial communities and enhancing their metabolic activity or by affecting the attachment of bacteria to epithelial cells.

Q: What type of pectin is best for jam?

A: So whatever the type of pectin you are using can easily be deciphered by the method of the recipe. If there is sugar and acidity in the recipe then use HM pectin. If you are making sugar free jam, use LM pectin or pectin NH.

Q: What does serine do for the body?

A: Serine is critical for the production of the body's proteins, enzymes and muscle tissue. Serine is needed for the proper metabolism of fats and fatty acids. It also helps in the production of antibodies.

Q: What foods are high in serine?

A: The top three food groups were meat/poultry/fish, grain products and milk/milk products.

Q: What are the symptoms of serine deficiency?

A: Serine deficiency disorders primarily cause neurological problems like congenital microcephaly, developmental delays, seizures, and spastic quadriplegia. These symptoms can manifest in infants, children, or adults, depending on the specific type of deficiency.

Q: How can I increase my serine levels naturally?

A: Therefore, dietary intake of serine is rather important for those auxotrophs and even healthy individuals. Our daily food provides a certain amount of serine, and the highest contribution comes from soy, eggs, fish, milk, nuts, and so on.
