It is only storing the last record because you are not creating a new JSONObject in your do...while loop. See my edited code.

JSONArray jsonArray = new JSONArray();
        JSONObject obj = new JSONObject();
        String DATABASE_NAME = "TEMPFOOD";
        String TABLE_NAME = "tempData";
        try{
            SQLiteDatabase mydb = openOrCreateDatabase(DATABASE_NAME, TempActivity.MODE_PRIVATE,null);
            Cursor allrows  = mydb.rawQuery("SELECT * FROM "+  TABLE_NAME, null);
            if(allrows.moveToFirst()){
                do{
                    obj = new JSONObject();
                    String Food_Name = allrows.getString(0);
                    String Value = allrows.getString(1);
                    String NOBAT = allrows.getString(2);
                    String TIME = allrows.getString(3);
                    String DATE = allrows.getString(4);
                    try {
                        obj.put("Food_Name", Food_Name)
                                .put("Value", Value)
                                .put("NOBAT", NOBAT)
                                .put("TIME", TIME)
                                .put("DATE", DATE);
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                    jsonArray.put(obj);
                }
                while(allrows.moveToNext());
            }
            mydb.close();
        }catch(Exception e){
            //Toast.makeText(getApplicationContext(), "Error", Toast.LENGTH_LONG).show();
        }
        String jsonText = jsonArray.toString();
