Problems solved by technology

[0003] However, Torreya torreya processing enterprises are all directly packaged and sold with shells after being stir-fried and processed. There is a single shortcoming of processed products. If the coating is not thorough, the black seed coating remaining on the surface of the torreya kernel will affect the appearance and taste of the torreya kernel during eating
At present, there are few reports on the market about the process of declothing Torreya kernels, so the development of a process for undressing Torreya kernels is of great significance for enriching the processed products of Torreya torreya, and has certain development prospects

Embodiment 1

[0027] A preparation method for freezing uncoated torreya kernels, comprising the steps of:

[0028] (1) Early pretreatment: Remove defective seeds, screen seeds with consistent shape, size, and color, and mix them to ensure sample uniformity. The sun-dried seeds were stored in a 4°C refrigerator until roasting.

[0029] Torreya seeds are dried with a water content of 10±2% (w / w). Shell the torreya.

[0030] (2) Freezing treatment: secondly, the torreya seeds were placed in a -80°C refrigerator for 24 hours of frozen storage.

[0031] (3) Thawing treatment: take the Torreya seeds out of the refrigerator and put them into a refrigerator at 4°C for about 10 hours to thaw.

[0032] (4) Baking processing: Toast the torreya that has been thawed in (3), set the first baking temperature to 200°C, bake for 11 minutes, and salt the torreya after the first baking The soaking solution is a saturated salt solution with a concentration of about 20% (w / w), soaking for 11 minutes; the se...

[0036] A preparation method for freezing uncoated torreya kernels, comprising the steps of:

[0037] (1) Early pretreatment: Remove defective seeds, screen seeds with consistent shape, size, and color, and mix them to ensure sample uniformity. The sun-dried seeds were stored in a 4°C refrigerator until roasting.

[0038] Torreya seeds are dried with a water content of 10±2% (w / w). Shell the torreya.

[0039] (2) Freezing treatment: Next, place the Torreya torreya seeds in a -20°C refrigerator for 24 hours of frozen storage.

[0040] (3) Thawing treatment: take the Torreya seeds out of the refrigerator and put them into a refrigerator at 4°C for about 10 hours to thaw.

[0041] (4) Baking processing: Toast the torreya that has been thawed in (3), set the first baking temperature to 200°C, bake for 11 minutes, and salt the torreya after the first baking The soaking solution is a saturated salt solution with a concentration of about 20% (w / w), soaking for 11 minutes; the seco...

[0045] A preparation method for freezing uncoated torreya kernels, comprising the steps of:

[0046] (1) Early pretreatment: Remove defective seeds, screen seeds with consistent shape, size, and color, and mix them to ensure sample uniformity. The sun-dried seeds were stored in a 4°C refrigerator until roasting.

[0047] Part of the torreya seeds with a water content of 10±2% (w / w) were dried. Shell the torreya.

[0048] (2) Freezing treatment: secondly, the torreya seeds were placed in a -60°C refrigerator for 24 hours of frozen storage.

[0049] (3) Thawing treatment: take the Torreya seeds out of the refrigerator and put them into a refrigerator at 4°C for about 10 hours to thaw.

[0050] (4) Baking processing: Toast the torreya that has been thawed in (3), set the first baking temperature to 200°C, bake for 11 minutes, and salt the torreya after the first baking The soaking solution is a saturated salt solution with a concentration of about 20% (w / w), soaking for 11 mi...

Abstract

The invention discloses a processing method of skin-less Chinese torreya kernels and belongs to the field of processing of agricultural and sideline products. Chinese torreya kernels undergo earlier preprocessing, the moisture content is adjusted, freezing processing is executed, unfreezing is executed, and Chinese torreya baking and processing are completed; skin removal and package are executed.Compared with a traditional process, the skin removal rate is improved by adopting a freezing and skin-removing method, the obtained Chinese torreya kernels have better quality, and all constitutional components are not degenerated. The processing method is simple in operation, free of contamination, low in energy consumption and easy to process, is conductive to energy saving and environment protection and conforms to the principle of sustainable development. The comprehensive utilization rate of Chinese torreya and the added value of Chinese torreya products are improved, and a new way is explored for deep Chinese torreya processing.

Description

technical field [0001] The invention belongs to the field of agricultural by-product processing, and in particular relates to a processing method of Chinese torreya. Background technique [0002] Torreya grandis (Torreya grandis cv. Merrillii) is an excellent variation type of Torreya (Taxaceae) through artificial grafting and propagation. It is a national second-class protected plant and a rare economic forest tree species unique to my country. Kuaiji Mountain, Shaoxing City, Zhejiang Province is the main planting area of ​​Torreya torreya, among which Zhuji City has the largest planting area, the highest yield and the best quality. Torreya nutritive value is high, and oil, protein, amino acid content are more. Torreya torreya is rich in trace elements needed by the human body and is a highly recommended edible nut with high economic value. The content of unsaturated fatty acids in Chinese Torreya oil is extremely rich, accounting for 78.89% of the total fatty acids. A l...
