As a long-term fava bean supplier working closely with food manufacturers, 植物ベースのプロテイン開発者, およびバルク原料購入者, 私たちはよく簡単な質問をされます:
ソラマメは本当に人々が主張するほど栄養価が高いのでしょうか?
The short answer is yes—but from a supplier’s perspective, nutrition facts are only meaningful when they are consistent, 測定可能な, and applicable in real production environments.
This article explains fava beans nutrition facts based on scientific evidence and our hands-on experience in supplying food-grade dried fava beans for commercial use.
What Are Fava Beans?
Fava beans (Vicia faba), also known as broad beans, are one of the oldest cultivated legumes in the world. They are consumed both as fresh green beans そして dried mature beans, with dried fava beans being the dominant form used in food manufacturing, plant protein processing, and bulk ingredient supply.
From a supply chain standpoint, dried fava beans are preferred because they offer:
Stable nutritional composition
Longer shelf life
Higher protein density per unit weight
そら豆の栄養成分表 (Per 100g)
Nutritional values can vary slightly depending on variety and processing, but the ranges below are well supported by analytical data and published research.
タンパク質含有量
Fava beans are a high-protein legume:
Dried fava beans: approximately 20–25 g of protein per 100 g, with some varieties reaching close to 30% protein on a dry matter basis
Fresh fava beans: approximately 8–10 g of protein per 100 g
From our experience supplying fava beans to food processors, this protein level makes them an excellent plant-based protein source, particularly suitable for:
Vegetarian and vegan diets
Protein fortification in cereal-based foods
Alternative protein formulations
Scientific studies confirm that fava bean protein has a balanced amino acid profile and good digestibility compared to many other legumes (Multari et al., 2015).
食物繊維
Fava beans are also rich in dietary fiber:
5–11 g of dietary fiber per 100 g
This fiber content contributes to:
Improved intestinal motility
Cholesterol reduction
Prolonged satiety and glycemic control
In commercial food applications, fiber-rich legumes like fava beans are frequently used in functional foods aimed at digestive health and weight management.
Vitamins in Fava Beans
Fava beans provide a broad range of vitamins, particularly B-complex vitamins, 含む:
Vitamin B1 (Thiamine)
Vitamin B2 (Riboflavin)
Vitamin B6
Folate (Vitamin B9)
Vitamin C
Vitamin K
Folate deserves special attention: it plays a critical role in DNA synthesis, red blood cell formation, and neural development, making fava beans nutritionally valuable for a wide range of populations (USDA, supported by peer-reviewed nutrition data).
Mineral Profile
Fava beans contain multiple essential minerals, のような:
Calcium – supports bone health
鉄 – essential for hemoglobin synthesis and prevention of iron-deficiency anemia
Potassium – helps maintain electrolyte balance and stable blood pressure
マグネシウム – involved in energy metabolism and muscle function
Zinc – supports immune function and growth
From a supplier’s quality-control perspective, mineral content stability is influenced by harvest maturity and drying methods, which is why standardized processing is critical for bulk supply.
Antioxidants and Bioactive Compounds
Beyond basic nutrition, fava beans contain several bioactive compounds, 含む:
Polyphenols
Flavonoids
These compounds exhibit antioxidant activity, helping to neutralize free radicals and potentially reduce the risk of chronic diseases such as cardiovascular disorders and metabolic syndrome (Boukid et al., 2019).
Other Functional Components in Fava Beans
Fava beans also contain naturally occurring compounds such as:
Phospholipids
Choline
L-DOPA (Levodopa)
L-DOPA is of particular scientific interest due to its role in dopamine synthesis and neurological function. While dietary intake alone is not therapeutic, studies confirm that fava beans are one of the richest natural food sources of this compound (Raina et al., 2014).
Low Fat, High Nutritional Density
Another advantage of fava beans is their low fat content, making them suitable for:
Low-fat diets
Heart-health-oriented food products
This combination—high protein, high fiber, low fat—is why fava beans are increasingly used in plant-based and clean-label formulations.
Why Nutrition Facts Matter to Buyers
From our role as a fava bean supplier, we see that buyers care less about theoretical nutrition values and more about:
Batch-to-batch consistency
Dry matter protein stability
Suitability for processing (milling, 押し出し, fermentation)
Well-documented nutrition facts allow manufacturers to formulate products with predictable outcomes, which is essential for scaling production.
最終的な考え: Nutrition Is Only Valuable When Supply Is Reliable
Scientific research clearly shows that fava beans are nutritionally excellent—rich in protein, dietary fiber, ビタミン, minerals, and antioxidant compounds, while remaining naturally low in fat.
しかし, from a supplier’s perspective, these nutrition facts only translate into real value when fava beans are:
Properly harvested
Carefully dried
Consistently graded and stored
That is why nutrition data and supply-chain expertise must go hand in hand.
FAQ
1. Are fava beans a good source of protein?
はい. Fava beans are considered a high-protein legume. Dried fava beans typically contain 20–25 g of protein per 100 g, and in some varieties protein content can approach 30% on a dry matter basis. This makes them an excellent plant-based protein source, especially for vegetarian and vegan diets.
2. How much protein is in fresh vs dried fava beans?
Fresh fava beans usually contain 8–10 g of protein per 100 g, while dried fava beans are much more concentrated, providing 20–25 g per 100 g due to lower moisture content. This is why dried fava beans are preferred in food manufacturing and bulk supply.
3. Are fava beans high in dietary fiber?
はい. Fava beans contain approximately 5–11 g of dietary fiber per 100 g, which supports digestive health, helps regulate cholesterol levels, and contributes to satiety. Their fiber content is one reason they are widely used in functional and health-oriented food products.
4. What vitamins are found in fava beans?
Fava beans are rich in B-complex vitamins, 含む vitamin B1, B2, B6, and folate (vitamin B9). They also provide vitamin C and vitamin K, which play important roles in metabolism, red blood cell formation, immune function, and bone health.
5. What minerals do fava beans contain?
Fava beans contain several essential minerals such as カルシウム, 鉄, カリウム, マグネシウム, リン, と亜鉛. These minerals support bone health, oxygen transport in the blood, electrolyte balance, immune function, and overall metabolic health.
6. Do fava beans contain antioxidants?
はい. Fava beans contain polyphenols and flavonoids, which are antioxidant compounds that help neutralize free radicals and may reduce the risk of chronic diseases, including cardiovascular and metabolic disorders.
7. Are fava beans low in fat?
Fava beans are naturally low in fat, making them suitable for low-fat diets and heart-health-focused food formulations. Their nutritional profile combines high protein, high fiber, and low fat, which is particularly attractive in plant-based food development.
8. Are fava beans suitable for food manufacturing and industrial use?
はい. From a supplier’s perspective, dried fava beans are widely used in plant protein production, functional foods, snacks, and bulk ingredient applications due to their stable nutritional composition, high protein density, and good processing performance.
9. Do fava beans contain any special bioactive compounds?
Fava beans naturally contain compounds such as choline, phospholipids, and L-DOPA (levodopa). L-DOPA is involved in dopamine synthesis and is one of the reasons fava beans are of scientific and nutritional interest.
10. Why is supplier quality important when evaluating fava beans nutrition facts?
Nutrition values are only reliable when the supply is consistent. Factors such as harvest maturity, drying method, moisture control, and storage conditions directly affect protein, fiber, and mineral stability. A reliable supplier ensures batch-to-batch nutritional consistency.
