Almond protein
Protein-rich ingredient made from almonds (often partially defatted flour or isolates) used to boost protein in foods.
Should I eat Almond protein?
Almond protein is a straightforward plant protein from almonds that can meaningfully raise protein in foods. It’s a good option for most people without nut allergies; check brands for solvent‑free processing and reputable contaminant testing.
Summary
This ingredient is typically made by mechanically pressing almonds and milling the press cake into a protein‑rich flour; some products are further concentrated with water‑based steps. It supplies plant protein with a mild taste and retains some minerals and polyphenols, though vitamin E declines when the oil is removed. Published DIAAS data for almond protein are limited, so it’s often blended with other plant proteins to balance amino acids. Key cautions are the tree‑nut allergy status, the need for aflatoxin controls, and processing differences (mechanical vs. solvent extraction), with organic rules prohibiting volatile synthetic solvents.

Why is it used?
Origin
Almonds (Prunus dulcis) were domesticated in Southwest Asia and spread through the Mediterranean before arriving in California in the 18-19th centuries. Modern 'almond protein' often comes from the press cake left after almond oil extraction, milled into partially defatted almond protein flour; some producers further extract and precipitate proteins to make isolates or concentrates. California now supplies most world almonds and has driven efficiency efforts (e.g., drip irrigation) to reduce water per pound produced.
Process: Defat and mill; optionally extract and precipitate

Research Summary
Digestive Effects
Most people tolerate almond protein well. Larger single servings may cause a sense of fullness or mild gastrointestinal discomfort in some individuals, similar to other concentrated proteins. If you are new to nut‑based proteins, start with smaller servings and see how you feel. People with known nut sensitivities should be cautious and consult their clinician before use.
Limit Consumption
People with tree‑nut allergy must avoid almond protein; U.S. law requires the label to name the nut (e.g., almond). It is not suitable as the sole protein source for infants and should only be used in age‑appropriate foods. Those who prefer to avoid solvent‑extracted ingredients can choose organic or ask brands to confirm solvent‑free processing. Individuals who need to limit exposure to potential contaminants should buy from reputable companies that test for aflatoxins.
