Popular questions
What is modified food starch?
A group of plant-based starches that have been physically, enzymatically, or chemically treated to change how they behave in foods—improving thickening, stability, freeze–thaw performance, or emulsification (E1400–E1452).
Is modified food starch gluten free?
Often yes when sourced from corn, potato, tapioca, or rice; if it’s from wheat, it can contain gluten unless specially processed and labeled gluten-free. In the US/EU, wheat-derived modified starch must be declared as “wheat,” so check the allergen statement or a gluten-free claim.
What is modified corn starch?
Modified starch made from corn that’s been treated to improve thickening, stability, and resistance to heat, acid, or shear; commonly used in sauces, soups, dressings, and desserts.
Is modified corn starch gluten free?
Yes—corn is naturally gluten-free, and modified corn starch remains gluten-free; only potential cross-contact is a concern, so rely on allergen statements or a gluten-free label if needed.
What is modified wheat starch?
Starch from wheat that has been modified to alter its functionality (e.g., thicker, more stable or freeze–thaw tolerant); it may retain some gluten unless specifically purified and labeled gluten-free. “Wheat” must appear in allergen labeling in many regions.
What is a peptone?
A peptone is a water‑soluble mix of short peptides, amino acids, and nutrients made by partial hydrolysis of proteins (e.g., casein, meat, or soy); it’s used as a nutrient source in culture media (tryptone is a casein peptone).
What is the purpose of peptone in the media?
It supplies readily assimilable nitrogen (peptides and amino acids), vitamins, and minerals to support microbial growth, including fastidious organisms.
How to make peptone water?
Dissolve 10 g peptone and 5 g sodium chloride in 1 L purified water, adjust pH to about 7.2 at 25°C, dispense, and sterilize by autoclaving at 121°C for 15 minutes.
What is buffered peptone water?
A phosphate‑buffered version of peptone water (per liter: peptone 10 g, NaCl 5 g, Na2HPO4 3.5 g, KH2PO4 1.5 g; pH ~7.2) used as a non‑selective pre‑enrichment medium to resuscitate stressed bacteria, especially Salmonella, from foods.
What is peptone in microbiology?
In microbiology, peptone refers to protein hydrolysates (from casein, meat, soy, etc.) rich in peptides and amino acids that serve as the main nitrogen source in culture media; different peptones (e.g., tryptone) can influence growth and test outcomes.
