Embodiment 1

[0019] One, the preparation of navel orange powder

[0020] Taking commercially available fresh Zigui navel oranges as raw materials, the nutritional indicators were determined according to the following methods:

[0021] Moisture measurement method: Turn on the blower in the oven, put the chopped navel oranges into a large petri dish, put the petri dish into the oven, and dry it for 48 hours at 55°C-60°C, turning over every two hours. Weigh after 48 hours. After the moisture drops below 10%, change to 105°C and dry continuously for 1 hour, then open the oven door slightly, wait for the temperature to drop slowly, cool for 10-15 minutes, and then enter the dryer to stabilize for 30 Minutes, weighed, and repeated drying at 105°C until the weight of the two weighings was constant. Moisture (%)=sample mass / total sample mass after drying;

[0022] Determination method of total protein: According to GB / T 5009.5, it is determined by Kjeldahl method;

[0023] Fat determination met...

Embodiment 2

[0058] One, the preparation of navel orange powder

[0059] Get commercially available fresh Gannan navel oranges as raw materials, measure its moisture, reducing total sugar, protein, fat, Vc and crude fiber content and other indicators according to the method described in embodiment 1 step one, the results are as shown in table 5:

[0060] Index determination of table 5 fresh sample navel orange

[0061]

[0062] The production steps of navel orange powder: raw material selection, cleaning, peeling, slicing, negative pressure far-infrared drying, uniform humidity, vacuum microwave puffing and drying, crushing, and packaging. The specific methods are as follows:

[0063] 1. Selection of raw materials: choose Pengna navel oranges with large fruit shape, bright orange red, crisp and tender flesh as raw materials;

[0064] 2. Cleaning and peeling: rinse with clean water and peel;

[0065] 3. Slicing: slice the cleaned and peeled navel oranges with a slicer, and the thicknes...

Abstract

The invention relates to a production process of navel orange powder and a product thereof and belongs to the field of deep processing of agricultural products. The production process comprises the following steps of: placing fresh sliced navel orange sheets in a negative-pressure far infrared dryer cavity to reduce the moisture content of the navel orange sheets to 50 to 55 percent, placing materials in a vacuum microwave dryer cavity, setting the microwave drying power to be between 2.2 and 3.2W / g and the vacuum degree to be between 0.075 and 0.090MPa, drying the navel orange sheets for 55 to 65 minutes to obtain bulked navel orange sheets, and finally performing supermicro crushing on the bulked navel orange sheets to obtain the navel orange powder. In the invention, the navel orange sheets are bulked, dried and crushed again, the whole drying process is finished under negative pressure and no any food additive is added, so that the instant solubility and the rehydration of the navel orange powder are improved, the colour and nutrient ingredients of the product are kept good and the product is easy to be digested and absorbed by human bodies.

Description

1. Technical field [0001] The invention relates to a production process of navel orange powder and a product thereof, belonging to the field of deep processing of agricultural products. 2. Background technology [0002] Navel orange is of high quality, seedless, juicy and bright in color. Navel oranges are rich in nutrition and contain various nutrients necessary for the human body. On average, every 100ml of fresh orange juice contains: 11-15% soluble solids, 11.0-13.0g total sugar, 0.80-0.95g citric acid, 0.9g protein, and 0.2% fat g, amino acid 203.9mg, vitamin A 0.127mg, vitamin B 1 0.08mg, vitamin B 2 0.03mg, vitamin C 55-75mg, and rich in calcium, iron, phosphorus and other elements. It is an excellent health-care and nutritious green food. Regular consumption has the effects of lowering cholesterol, decomposing fat, reducing the accumulation of non-ferrous metals and radioactive elements in the human body, clearing fire and beautifying skin, preventing and fighti...
