Grape seed

We often hear about grape seeds in the context of oils. The fluid extracted from the seeds is suitable for everything: toning sensitive skin around the eyes, nourishing dry hair, aromatic massage and even cooking.

Is this really so and what is better to do with the product - eat or apply to the skin?

General characteristics

Grapes are a genus of plants that belong to the Vinogradov family.
The most significant species is cultivated grapes. It is this plant that provides raw materials for winemaking, gastronomic, medicinal and cosmetology industries.

Biological description of the plant

The plant forms long shoots called the vine. Seed appears in the first year of germination of a miniature shoot. From the formed buds, elongated, dense and well-developed vines grow throughout the year. Plant growth occurs due to the alternation of powerful elongated and newly formed shoots. Agronomists and gardeners are used to pruning grapes briefly, so this alternation is usually invisible. Flowering and fruiting of grapes occurs once a year.

The flowers are formed small, collected in inflorescences from a panicle and a complex brush. Flowers can be bisexual or split into true male / true female. Most varieties have bisexual flowers.

Grape fruits - berries of a round or ovoid form, which are combined by one loose or dense bunch. The color of the fruit depends on the variety. Several seeds are hidden inside each grape, but seedless varieties are also found, for example, white raisins.

Grapes are a non-waste product. Both the flesh and the bones are used by man. Oil is extracted from grape seed by hot extraction or cold pressing. It is added to food, cosmetic lines for skin and body care, used in pharmacology.

Is it possible to eat grapes with seeds?

Most fruit seeds and plant seeds that a person can chew do not pose a serious danger to a healthy body. One of the myths that surround this issue is the risk of appendicitis. In theory, grape seeds can actually provoke inflammation of the appendix of the cecum, but the likelihood of such a development of events is minimal. Doctors do not focus on this and do not attribute grape seeds to the main causes of inflammation of appendicitis.

Appendicitis becomes inflamed in only two cases - mechanical blockage or kink. A less common cause is an accidental ingestion of a foreign body that cannot be digested (toys, small parts, etc.).

Moreover, even if the body is not able to qualitatively absorb the whole bone (for example, due to illness), then a person can help himself - by chewing the product thoroughly. The bone rarely enters the body. We chew it and facilitate the work of the digestive tract.

Bones abound in fiber, tocopherol (vitamin E) and minerals.

They help cleanse the stomach, speed up metabolic processes and slow down the aging process. Moreover, the bones are considered conditionally "clean." They are inside the berry and protected from pathogenic bacteria.

The seeds of apricot, cherry, peach and plum should not be eaten as freely as grape. They contain the substance amygdalin or vitamin B17. Information about its anti-cancer activity turned out to be falsification, after which the FDA (Food and Drug Administration) banned the component due to its high toxicity.

What you need to know about grape seed oil?

This vegetable oil is a by-product of winemaking. It is used in several industries:

  • cosmetology (for the manufacture of facial, hair and body care products);
  • pharmaceuticals (for antioxidant drugs, normalization of pressure / cholesterol / visual organs, improving brain activity, treatment of attention disorders);
  • gastronomy (for cooking oil, which is used for frying, baking and salad dressing).

The popularity of the product has increased over the past few years, due to the demand for a healthy diet and lifestyle. From the shelves with organic products, oil migrated to ordinary sunflower oil, which is not inferior either in variety or in the number of producers.

The plant product is characterized by powerful antioxidant activity. It contains three important vitamins at once - retinol (A), tocopherol (E) and ascorbic acid (C). Another important element of the composition is chlorophyll. It brings the epithelium into tone and starts the process of restoration of both external and internal damage. Chlorophyll also helps prevent kidney stones.

Product Benefits

Grape seed oil is based on unsaturated fats. Is it good or bad? Modern society is just beginning to learn the basics of nutrition. Most people believe that fatty foods are a direct source of fat at the waist and do not distinguish between the fat from deep fat and grape seed fat. We will deal with the second.

Unsaturated omega fats, which make our vessels elastic, regulate cholesterol levels, activate blood circulation. In addition to internal health, they are also responsible for external attractiveness - they make the face shining, hair strong, teeth white, and nails long.

Unsaturated fatty acids abound in fish and seafood, but not everyone can afford a Mediterranean diet daily. The same omega can be found in cheaper plant foods. What is useful grape seed oil:

  • improves the functionality of the cardiovascular system, carries out a kind of prevention and protects it from diseases;
  • strengthens and increases the elasticity of blood vessels;
  • regulates cholesterol, prevents the formation of plaques and blood clots;
  • accelerates metabolic processes, increases the percentage of absorption of useful nutrients;
  • has a regenerating effect;
  • beneficial effect on the female reproductive system - helps to establish lactation, relieves pain during the menstrual cycle and menopause, supports the body during pregnancy;
  • helps increase libido in men, improves the functioning of the prostate gland;
  • improves the protective functions of the immune system;
  • helps fight acne and post-acne (with a competent individual dermatological approach).

Product Use Areas

Cosmetology

A herbal ingredient is added to cosmetics to moisturize (not nourish) the skin. It gives the epithelium a velvety structure, fills it with vitamins / minerals and envelops it with a pleasant sweetish smell. The product is often used for aromatherapy and as a protective nutrient before shaving.

The component can be used not only in salon, but also in home care. Based on it, you can prepare a scrub, moisturizing day / night cream or homemade shampoo. If a scrub or cream requires only a flight of imagination and compliance with the needs of the skin, it is more difficult with homemade shampoo - it should foam, not clog pores and thoroughly rinse hair. But the formula of homemade shampoo is simple - mix the necessary ingredients with a base mild soap. For example, Castilian is perfect for normal hair.

The main thing is to thoroughly massage the scalp when applying shampoo. The oil will saturate the skin with tocopherol, vitamins and collagen. The components contribute to the tone, rejuvenation of the skin and the formation of a silky hair structure. A basic mild soap will help neutralize the greasy effect, so washed hair will be smooth, silky and free of a viscous lipid film.

If you used to constantly use sulfate shampoos, then the transition to natural cosmetics will be long and possibly time-consuming. The main thing is to evaluate the reaction of the hair, wash it with organics more often and give time to adapt to a new beauty ritual.

Grape seed oil is classified as medium comedogenic. What does it mean?

Comedogenicity is one of the characteristics of cosmetics. It determines the ability of cosmetics to cause the formation of comedones. The more the ingredient pollutes the skin and clogs the pores (which interferes with the free removal of toxins through the epithelium), the higher the degree of comedogenicity.

Dermatologist James E. Fulton created his own list of comedogenicity of components, which is based not on individual, but on general cases. Comedogenic care products are much more likely to provoke the development of cosmetic acne. These are acne that appears due to improperly selected cosmetics.

Grape seed oil is in the middle of the list. Owners of especially sensitive or problematic skin need to carefully test cosmetics with a herbal ingredient so as not to aggravate the condition of the skin.

The specificity of the effect of comedogenic or non-comedogenic ingredient depends on the individual characteristics of the skin. For example, comedogenic coconut oil can provoke acne on oily skin, but nourish dry skin well. The same story with grape seed oil. To determine the skin's need for this particular product - test and follow the advice dermatologically.

Gastronomy

Grape seed oil has a subtle sweet taste and rich plant-nut aroma. Such a combination will perfectly complement vegetable salads, meat / fish dishes. Even the familiar pasta will be revealed from a completely new perspective, if you add new vegetable oil to the sauce. On the basis of the product, traditional sauces such as mayonnaise are prepared, added to pastries and pastries.

Grape seed oil has a high heating point of 216 ° C.

Heat treatment does not change the composition of the product and does not make it toxic. Grape seed oil is perfect for relatively harmless frying, baking and deep fat.

The product is resistant to oxidation, therefore, its implementation time is an order of magnitude higher than that of other vegetable oils, it is 12 months from the date of manufacture. Before opening containers, it is best to store oil at room temperature, avoiding ultraviolet exposure. After opening, put the container in the refrigerator - low temperature will not affect the composition, aroma, taste and texture of the product.

The medicine

An extract from grape seed is added to the medicine due to the abundance of polyphenolic compounds. They have a powerful antioxidant effect and:

  • strengthens the connective tissue of arteries, capillaries and veins;
  • solve the problem of blood microcirculation disorders;
  • relieve swelling;
  • prevent blood clots;
  • normalize pressure;
  • regulate cholesterol in the body
  • eliminate varicose veins.

Also, the component is added to medications to stimulate brain activity, in case of attention disorders, age-related deterioration of vision and destruction of the retina. Polyphenols also have a powerful antihistamine effect.

How to choose a plant product?

There are two methods for making oil - hot extraction and cold pressing.

Extraction involves extracting oil from the bone using a special solvent - extractant. The solvent is chosen on the basis of basic raw materials - it should not be mixed with the finished oil. When cold pressed, the bones are crushed, pressed and, in the literal sense, oil is squeezed out of them. The process takes place at low temperatures.

Nutritionists argue that hot extraction kills all the beneficial properties of the product, makes it toxic and harmful to the human body. Cold pressed, on the contrary, is as safe as possible for the chemical composition and for the useful properties of the finished product.

For cooking, always choose cold-pressed vegetable oils.

Give preference to oils that are stored in glass containers. This is a kind of confirmation of product safety. It is best if the glass bottle is dark, which further protects the product from ultraviolet radiation.

Sediment may form at the bottom of the container. This does not indicate poor quality, expired sales or improper storage conditions for the goods. The precipitate is formed due to the oxidation of fat - this is a natural process that does not affect the quality of the oil. If the liquid is slightly warmed up or left at room temperature, the precipitate will disappear.

The color of the grape oil should be dark green or yellow. Hue may vary depending on the plant pigment chlorophyll. The more it is, the greener the liquid. If possible, appreciate the aroma of oil. It should be light, nutty with bright plant notes. It is best to refuse a product with a putrid or repulsive odor.
