Description

EFFICIENT AND HIGH-QUALITY PREPARATION METHOD OF FLAVOR VEGETABLE SOLUBLE RECONSTITUTED BEANS BASED ON KALE
Technical Field
The present invention discloses an efficient preparation method of high-quality
flavor vegetable soluble reconstituted beans based on kale, and belongs to the field of
food processing.
Background
The kale is a cruciferous brassica vegetable and has abundant nutritional
ingredients such as glucosinolate, chlorophyll, carotenoid and vitamin. The secondary
metabolite - glucosinolate contained in the kale can reduce the risk of suffering from
cancer and cardiovascular and cerebrovascular diseases. The chlorophyll contained in
the kale can be used as a natural pigment component so that food presents fresh green.
Moreover, the kale is also a good source of dietary carotenoid. A research report of
the Centers for Disease Control and Prevention shows that the kale ranks 15th in the
fruit and vegetable "power station". However, the kale is bitter and is rarely used for
raw food. At present, the development of the processing products of the kale is also
very limited, and is still in the initial stage. Yogurt contains more proteins,
carbohydrates, calcium and some vitamins compared with ordinary milk. Moreover,
the yogurt is fermented and is more suitable for human digestion and absorption.
Commercially available low-temperature yogurt has mild sour and sweet, but is
generally short in shelf life and harsh in storage conditions (under low temperature environment). The kale is mixed with the yogurt. The mixture is blended and dried to prepare a soluble reconstituted bean product. Not only the taste of the kale can be blended, but also the shelf life of the kale and the yogurt can be prolonged.
The soluble reconstituted bean is a small snack that can be dissolved in the
mouth, and is favored by consumers in recent years due to its characteristics of health
and low fat. At present, most processing modes of commercially available
high-quality soluble reconstituted beans are lyophilization, and have long drying time,
high energy consumption and expensive operating cost, thereby greatly limiting the
development and production of the soluble reconstituted bean products. Therefore, it
is extremely important to find an efficient drying mode to produce the high-quality
soluble reconstituted beans.
Infrared lyophilization is a novel drying mode that uses infrared radiation as a
heat source for lyophilization. Infrared radiation is an electromagnetic wave with a
wavelength range of 0.78-1000 mm. The heating process of infrared radiation does
not need a medium. Infrared radiation can directly reach the surface of an object
without heating the surrounding air, and thus has high thermal efficiency. Infrared
lyophilization combines the advantages of infrared radiation and lyophilization, has
higher drying efficiency than the traditional lyophilization technology, and can enable
the dried materials to have shapes and structures, tastes and nutritional quality
equivalent to those of the traditional lyophilization.
Microwave vacuum drying is a heating and drying mode based on vacuum
drying and using microwave as a heat source. A vacuum environment can evaporate
the water in the material to be dried at lower temperature. Microwave heating has certain penetrability and higher drying efficiency. Thus, this drying mode is low in used temperature and high in drying rate, can better retain the nutritional quality of the material, and is often used to dry heat sensitive material.
Infrared lyophilization and microwave vacuum drying respectively have
advantages and disadvantages. For example, infrared lyophilization has longer drying
time than microwave vacuum drying. The microwave vacuum drying has short drying
time, but is not suitable for drying slurry with higher moisture content because high
vacuum environment and microwave heating are easy to splash the slurry in a drying
chamber. The mixed drying mode combines the advantages of two drying modes,
overcomes the defects of the two drying modes, and efficiently produces high-quality
products.
The processing of the soluble reconstituted beans has been publicly reported.
Chen Zhiping (application number 201810792053.X) discloses a method for
preparing lyophilized fruit, vegetable, cereal and yogurt blocks. Fruit and vegetable
pulp, cereals and yogurt are blended, and then lyophilized for 18 to 40 h to obtain a
small snack with long shelf life, convenient eating and balanced nutrition. Zhan Kai
and Zhao Guiju (application number 201610024897.0) mix fruit, vegetables, cereals
and yogurt, season the flavor through dextrose and maltodextrin, add modified starch
and skim milk powder for adjusting nutritional ingredients, and conduct
lyophilization of 26-30h to invent a soluble reconstituted bean of fruit, vegetables,
cereals and yogurt. Wang Mingquan et al. (application number 201710826956.0)
disclose a lyophilized whey cheese soluble reconstituted bean and a preparation
method thereof. The major raw materials are whey cheese, fruit and vegetable powder, a thickener and an acidity regulator; and the used lyophilization time is 20-30h. Li
Yutong et al. (application number 201711436382.2) invent a yogurt soluble
reconstituted bean with normal temperature storage, good shelf life stability and
application for eating of infants through lyophilization. The major ingredients are
sucrose, single cream, protein powder, an emulsifier, pectin, gelatin, starch and
vitamins. Ma Fei et al. (application number 201510678061.8) mix pure milk, a rice
bran peptide solution, red date pulp, carrot pulp, honeysuckle, tangerine peel, sophora
flower, a pueraria extracting solution, caster sugar and fructose syrup, and conduct
lyophilization to invent a nutritious rice bran polypeptide soluble reconstituted bean.
In the above five inventions, traditional lyophilization is used for processing and
producing the soluble reconstituted bean. Although the obtained product is nutritious
and good in quality, the used drying time is very long on average of 20-30h and the
energy consumption is high. The present invention uses a combined drying mode of
infrared lyophilization and microwave vacuum drying. The drying time of the soluble
reconstituted bean is greatly shortened, and a soluble reconstituted bean product with
good shape and appearance, high pigment retention rate, strong oxidation resistance
and good taste can be obtained. In terms of the main components of the formula, the
present invention is significantly different from the above five inventions in that: the
present invention uses whey protein powder with high human absorption rate and
reasonable amino acid composition as the nutrition enhancing component of the
vegetable soluble reconstituted bean, uses cassava pre-gelatinized starch to replace
the ordinary raw starch, gelatin, pectin and other components in the above inventions
to thicken and shape the pulp, and also uses the sweetener of xylitol to replace the frequently-used sucrose.
Ma Jie et al. (application number 201810271733.7) disclose a low temperature
puffed live bacteria yogurt soluble reconstituted bean and a preparation method
thereof. Yogurt, sucrose, skim milk powder, unsalted butter, maltodextrin and tapioca
starch are mixed, and subjected to reduced pressure puffing shaping and drying for
-17h through a low temperature puffing technology of 30-45°C to prepare a puffed
yogurt soluble reconstituted bean with loose and porous surface. The patent only uses
a low temperature vacuum puffing technology without the assistance of other heat
sources, and is long in drying time and difficult to control the shape of the soluble
reconstituted bean. In the present invention, firstly, infrared lyophilization is used to
dry and shape the slurry, and then microwave vacuum drying is used to accelerate the
drying process of the soluble reconstituted bean. The shape of the soluble
reconstituted bean obtained by this process is easy to control, and infrared ray and
microwave are used as heating sources, so that the drying efficiency is higher. In
terms of the main components of the formula, the tapioca starch used in the above
invention has a gelatinization temperature of about 60 to 70°C, and cannot be
gelatinized during low temperature (30 to 45 °C) processing, which may cause
difficult digestion of the product. The present invention adds easy-to-digest cassava
pre-gelatinized starch, so that the soluble reconstituted bean product can also have
good digestive performance at lower processing temperature (40-60°C).
Qiao Yingxin et al. (2019) makes a cheese soluble reconstituted bean through a
baking technology by using yogurt, corn starch, egg white, caster sugar and baby
milk powder as raw materials. Baking temperature is 90°C, and baking time is 60min.
The obtained cheese soluble reconstituted bean has thick milky flavor and better
sensory quality. Duan Qiuhong et al. (2018) bake egg white, yogurt and corn starch as
major raw materials in an oven at 100°C for 60min to obtain a yogurt soluble
reconstituted bean with rich aroma, delicate taste and instant dissolving in the mouth.
Kong Weihai (application number 201710810063.7) discloses a vinegar powder
soluble reconstituted bean suitable for infants to eat and a preparation method thereof.
Flour, fruit vinegar, yam flour, eggs, milk powder, fillers and citric acid as raw
materials are mixed, decorated and baked in an oven at 130-150°C for 10-15min to
prepare the soluble reconstituted bean. Yan Qiang discloses a preparation method of a
pitaya soluble reconstituted bean (application number 201711089152.3) and a
preparation method of a highly nutritious pumpkin soluble reconstituted bean
(application number 201711088112.7). Pitaya juice or pumpkin puree, egg yolk,
whole milk powder and honey as ingredients are baked in an oven at 180°C for
-30min to prepare the pitaya or pumpkin soluble reconstituted bean. The above five
studies use a high temperature baking mode to process the soluble reconstituted bean.
Although the processing time is greatly shortened, the high temperature (90-180°C)
will greatly lose the nutritional components in the soluble reconstituted bean. In the
infrared lyophilization and the microwave vacuum drying used in the present
invention, the set temperature is not greater than 60°C, and the nutritional quality of
the soluble reconstituted bean can be better maintained. In terms of the product
formula, the present invention uses high-quality whey protein to replace the egg
white or the egg yolk in the above invention to act as the protein enhancing
component of the product. Moreover, the cassava pre-gelatinized starch used in the present invention avoids the trouble of high-temperature gelatinization of the raw starch, and is suitable for processing under lower temperature conditions.
Summary
It would be advantageous to provide an efficient preparation method of
high-quality flavor vegetable soluble reconstituted beans based on kale. Kale and
yoghurt are used as main raw materials, and cassava pre-gelatinized starch syrup,
whey protein powder, skim milk powder, xylitol and citric acid are used as auxiliary
materials. The above materials are subjected to infrared lyophilization and microwave
vacuum drying to prepare a high-quality soluble reconstituted bean having good
shape and appearance, containing rich chlorophyll, carotenoid and total phenol and
having certain antioxidant capacity.
