Comparing E640 - Glycine and its sodium salt vs E642 - L-lysine hydrochloride

Overview

E640 - Glycine and its sodium salt

Glycine (and its sodium salt, sodium glycinate) is a simple amino acid used in foods mainly as a flavor enhancer and taste balancer. Labeled in the EU as E640, it can round off harsh or bitter notes without adding strong flavor of its own.

E642 - L-lysine hydrochloride

L-lysine hydrochloride (E642) is the hydrochloride salt of the essential amino acid L‑lysine. Food makers use it mainly to add lysine to foods, helping improve protein quality, and it can subtly round out flavor in protein-rich formulations. It is authorized as a food additive in the EU and permitted as a nutrient supplement in the United States.

Popular questions

  1. Clean install on dell e640 which drivers?

    This appears unrelated to food additive E640; in foods, E640 means glycine and its sodium salt (sodium glycinate), used mainly as a flavor enhancer and buffering/chelating agent.

  2. Einstein e640 not working when hot?

    This isn’t about additive E640; glycine and its sodium salt are heat‑stable at normal cooking temperatures and are generally considered safe at typical food-use levels.

  3. How many times has einstein e640 flash fired?

    There’s no “flash count” for E640—it's the code for glycine/sodium glycinate, a food additive often used at quantum satis (good manufacturing practice) levels where permitted.

  4. How to do flash exposure bracketing with einstein e640?

    Unrelated to the additive: E640 (glycine/sodium glycinate) enhances savory/sweet notes and can help mask bitterness; it doesn’t involve any photographic exposure settings.

  5. How to fix a dell latitude e640?

    This seems unrelated to E-number E640; note that glycine may be produced synthetically or derived from animal sources (e.g., gelatin), so vegans should check sourcing or labeling.

  1. How long "freeze" nα-tosyl-l-lysine chloromethyl ketone hydrochloride ≥96% (tlc), powder?

    That refers to TLCK, a lab reagent, not the food additive E642. L‑lysine hydrochloride (E642) is typically stored dry at room temperature in airtight containers—not frozen—and remains stable for long periods if kept cool and dry.

  2. How long freeze nα-tosyl-l-lysine chloromethyl ketone hydrochloride ≥96% (tlc), powder?

    This is about TLCK, not the food additive E642. E642 (L‑lysine hydrochloride) is stored dry at ambient conditions in sealed packaging and does not require freezing; it’s stable when kept cool and dry.

  3. How to change fan in dell e642?

    This is unrelated to the food additive E642. L‑lysine hydrochloride (E642) is a food flavor enhancer/nutrient, not a laptop component.

  4. What does l lysine hydrochloride do?

    In foods it acts mainly as a flavor enhancer (E642), subtly boosting savory/sweet notes, and as a source of the essential amino acid lysine for fortification.

  5. What is difference between l lysine hydrochloride and lysine mono hydrochloride?

    None—“L‑lysine hydrochloride” and “L‑lysine monohydrochloride” are the same salt (E642); the latter just specifies one equivalent of HCl.
