Problems solved by technology

Peanut butter is widely used in various fields such as noodle products and hot pot dipping sauce. However, peanut butter has high fat content and is not suitable for people with high blood pressure and diabetes. The middle and non-fat part naturally settles to form a hard solid substance during storage, resulting in reduced flavor quality and shorter shelf life of peanut butter

preparation example Construction

[0089] The preparation process of peanut oil may also include at least one of the following steps: screening, impurity removal, crushing, filtration, clear oil, clarified oil, degumming, deacidification, dewaxing, degreasing, decolorization, transesterification, hydrogenation and / or deodorization.

[0090] In a specific embodiment, the preparation of peanut oil further includes: at least one step of screening, impurity removal, filtration, clear oil, oil clarification, and degumming.

[0091] Usually, the peanuts are soaked in water for a period of time, so that the water absorption rate of the peanuts reaches 30% to 55%. After draining, place them on the germination equipment to make the peanuts in a critical soaking state (such as laying flat on a seedling tray with gauze, Add water to the lower layer of the seedling tray, keep the upper layer on the water surface and the bottom of the upper layer of the seedling tray in a critical infiltration state), carry out light germina...

Embodiment 1

[0141] Take 200g of peanut raw materials with the same particle size and mature plumpness, add 2000g of deionized water to soak for 6 hours after cleaning, the water absorption rate is 31.99%, drain, spread on the seedling tray, and place at constant temperature and humidity (25°C, 100%) In the light laboratory, irradiate at a wavelength of 455-350nm for 18 hours, dry the germinated peanuts, squeeze the oil with a screw oil press, and obtain peanut oil 1 after filtration.

Embodiment 2

[0143] Take 200g of mature and plump peanut raw materials with the same particle size, add 4000g of deionized water to soak for 12h after cleaning, the water absorption rate is 52.18%, drain, spread on the seedling tray, and place at constant temperature and humidity (25°C, 50%) In the light laboratory, irradiate at a wavelength of 455-350nm for 24 hours, dry the germinated peanuts, use a screw oil press to extract oil, and obtain peanut oil 2 after filtration.

Abstract

The invention provides a peanut product. The peanut product is prepared from peanuts germinated under illumination of a specific wavelength. The peanuts only need to be germinated under illumination of a certain wavelength and then are treated, so operation is easy; the resveratrol content of peanut oil can be obviously improved, and the nutrition and application performance of the peanut oil are improved; and the content of gamma-aminobutyric acid in peanut butter can be remarkably increased, and the nutrition and application performance of the peanut butter are improved.

Description

technical field [0001] The invention belongs to the field of edible oils and fats, and specifically relates to a peanut product and a preparation process thereof, and more specifically relates to a peanut oil or peanut butter and a preparation process thereof. Background technique [0002] Peanut is a plant containing natural resveratrol discovered after resveratrol, knotweed, and grape. Compared with the first three plants, peanut has the advantages of abundant resources, low price, popularity, and edibleness. It is a scientific work. the key research object of the author. Peanut is an important oil crop in my country, and oil production is its most important use. According to existing research, germination is an effective way to enrich resveratrol in peanuts. , is a non-flavonoid polyphenol compound, the chemical name is 3,5,4'-trihydroxystilbene, and the molecular formula is C 14 h 12 o 3 , resveratrol has a good anti-oil oxidation effect, but also has high biological ...
