Problems solved by technology

However, there are two key restrictive factors in the use of cassava as a feed material: 1. Fresh cassava contains linolenoside, which can cause hydrocyanic acid poisoning when gastric juice is digested and hydrolyzed
2. After fresh cassava is excavated, it will usually be completely moldy within 3 days and cannot be eaten

Embodiment 1

[0013] 100 kg of fresh cassava, 50 kg of lactic acid bacteria liquid, the lactic acid bacteria in the lactic acid bacteria liquid is Lactobacillus acidophilus, and the density of Lactobacillus acidophilus is 1×10 4 cfu / ml, soak 100 kg of fresh cassava directly in a container containing 50 kg of lactic acid bacteria liquid, let the cassava completely sink into the bacterial liquid, without sealing it, it can be stored at room temperature for 2 months without decay.

Embodiment 2

[0015] 100 kg of fresh cassava, 50 kg of lactic acid bacteria liquid, the lactic acid bacteria in the lactic acid bacteria liquid is Lactobacillus casei, and the density of Lactobacillus casei is 1×10 7 cfuml, slice 100 kg of fresh cassava and soak it directly in a container containing 50 kg of lactic acid bacteria liquid, let the cassava completely sink into the bacterial liquid, without sealing it, it can be stored at room temperature for 3 months without decay.

Embodiment 3

[0017] 500 kg of fresh cassava, 50 kg of lactic acid bacteria liquid, the lactic acid bacteria in the lactic acid bacteria liquid are Lactobacillus casei and Lactobacillus fermentum, and the density of lactic acid bacteria is 1×10 8 cfu / ml, cut 100 kg of fresh cassava into strips and soak them directly in a bucket containing 50 kg of lactic acid bacteria solution for 1 hour, then remove and drain the bacteria solution, then put the cassava strips soaked in bacteria into plastic bags and tie the mouth Keep airtight in a cool place away from light. It can be stored at room temperature for 6 months without rot.

[0018] Soaking cassava with lactic acid bacteria liquid can not only reduce or eliminate the toxicity of linalin through bacterial degradation and water solubility, but also use the natural antibacterial activity of lactic acid bacteria liquid to inhibit the growth of mold or other harmful bacteria, prevent cassava from spoilage, and prolong storage Expect.

Abstract

The invention discloses a method fore storing fresh cassava. The method comprises the step of soaking the fresh cassava into lactic acid bacteria liquid to be stored, wherein lactic acid bacteria are selected from one or more of lactobacillus casei, lactic streptococci, lactobacillus plantarum, lactobacillus bulgaricus, lactobacillus acidophilus, lactobacillus fermenti, lactococcus lactis, streptococcus thermophilus, leuconostoc mesenteroides, bifidobacterium and pediococcus acidilactici; and the flora density of the lactic acid bacteria liquid is 1*104 to 1*1012 cfu / ml. The method is simple and easy to operate, and fresh cassava can be stored for 6 months and can not be decayed.

Description

technical field [0001] The invention relates to a method for preserving fresh cassava. Background technique [0002] Cassava is one of the three largest potatoes in the world and is widely cultivated in tropical and subtropical regions. In the subtropical region of my country, cassava is the fifth largest crop after rice, sweet potato, sugar cane and corn. Cassava, as a high-yielding crop rich in energy substances such as starch and cellulose, can be used not only for human consumption and as industrial products, but also as feed raw materials for breeding, including livestock and poultry breeding and aquaculture. [0003] Although the price of cassava as a feed raw material is much lower than that of corn, rice and other food crops, if it can replace the amount of corn in large quantities, it can not only save food, but also greatly reduce the feed cost of aquaculture. However, there are two key restrictive factors in the use of cassava as a feed raw material: 1. Fresh c...
