Embodiment 1
[0031] A preparation method of jujube chips, comprising the following steps:
[0032] 1) Handling of raw materials:
[0033] Select dry dates with no mildew, no pests and diseases, no mechanical damage, large jujube meat, and large jujube shapes. Wash them with clean water for 2 to 3 times to remove the dust on the jujubes. Put the cleaned jujubes in a mass concentration of 0.4%. After soaking in the iso-VC sodium solution for 12 hours, take it out, weigh and remove the core, according to the mass ratio of jujube raw material: iso-VC sodium solution at a ratio of 1:4, put the de-nucleated red dates into 0.4% mass percent concentration Carry out color protection in the different VC sodium solution, obtain the jujube raw material after processing;
[0034] 2) Beating:
[0035] The processed jujube raw material obtained in step 1) and water are beaten in a beater according to the mass ratio of 1:4 (beating speed is 800 rpm, time is 30s), and the residue is filtered with a 40-me...
Embodiment 2
[0047] Most of them are the same as in Example 1, the difference is that in step 2), the beating time is 40s; in step 3), sunflower kernels are added, and the shape of the grinding tool is round; in step 4), the cooking temperature is 110 °C, the cooking time is 5 min; in step 5), the aging temperature is 1 °C, and the circulating cold air flow rate is 3 m / s.
Embodiment 3
[0049] Most of it is the same as Example 1, except that in step 2), the beating time is 35s; in step 3), pine nut kernels are added, and the shape of the grinding tool is animal shape. In step 4), the cooking temperature is 107°C, and the cooking time is 10 minutes; in step 5), the aging temperature is 2°C, and the circulating cold air flow rate is 4m / s.

Abstract
The invention discloses a preparation method of red dates chip. The method comprises the following steps: 1) raw material treatment; 2) beating; 3) sizing; 4) starch gelatinization; 5) starch aging; 6) hot wind drying; and 7) microwave puffing drying. The preparation method of the red dates chip provided by the invention has the following advantages: red dates slurry is added with starch and subjected to microwave puffing to obtain a non-fried recombinant red dates chip with good formability and sensory quality; the method has great significance for development and utilization of fallen red dates and inferior red dates; cooking gelatinization and low-temperature rapid aging can effectively remove water in blank, so as to improve taste, brittleness and comprehensive sensory quality of the red dates chip; the red dates chip product can be prepared into a variety of shapes, has crispy taste, rich red dates flavor, dark red color, uniform and fine surface, good puffing effect and promising market prospect; the process has low energy consumption and high drying efficiency; and different dried fruits and nutlets are added in the sizing process to improve nutritional characteristics of a finished product of red dates chip.
Description
technical field [0001] The invention relates to the field of food processing, in particular to a preparation method of jujube chips. Background technique [0002] Hotan is located in the southern Xinjiang region, at 36.6°-37.1° north latitude, and is recognized as a "fruit eugenics area" in the world. The 15 hours of sunshine provide more sufficient photosynthesis for Hetian jujube, and the frost-free period of more than 220 days throughout the year makes the maturity period of Hetian jujube longer. The irrigation of alkaline sandy soil and iceberg snow water makes Hetian jujube richer in minerals. It has the most suitable pollution-free alkaline sandy soil for jujube growth, abundant light and heat resources, and Kunlun Mountain glaciers and snow water resources rich in mineral elements. [0003] However, in the past, most of the development of red dates was limited to the production of dried dates, and the requirements for dried dates were relatively high. The taste and...
